NAME
Test2::Tools::Compare - Tools for comparing deep data structures.
DESCRIPTION
Test::More had is_deeply(). This library is the Test2 version that can
be used to compare data structures, but goes a step further in that it
provides tools for building a data structure specification against which
you can verify your data. There are both 'strict' and 'relaxed' versions
of the tools.
SYNOPSIS
use Test2::Tools::Compare;
# Hash for demonstration purposes
my $some_hash = {a => 1, b => 2, c => 3};
# Strict checking, everything must match
is(
$some_hash,
{a => 1, b => 2, c => 3},
"The hash we got matches our expectations"
);
# Relaxed Checking, only fields we care about are checked, and we can use a
# regex to approximate a field.
like(
$some_hash,
{a => 1, b => qr/\A[0-9]+\z/},
"'a' is 1, 'b' is an integer, we don't care about 'c'."
);
ADVANCED
Declarative hash, array, and objects builders are available that allow
you to generate specifications. These are more verbose than simply
providing a hash, but have the advantage that every component you
specify has a line number associated. This is helpful for debugging as
the failure output will tell you not only which fields was incorrect,
but also the line on which you declared the field.

},
"Hash matches spec"
);
COMPARISON TOOLS
$bool = is($got, $expect)
$bool = is($got, $expect, $name)
$bool = is($got, $expect, $name, @diag)
$got is the data structure you want to check. $expect is what you
want $got to look like. $name is an optional name for the test.
@diag is optional diagnostics messages that will be printed to
STDERR in event of failure, they will not be displayed when the
comparison is successful. The boolean true/false result of the
comparison is returned.
This is the strict checker. The strict checker requires a perfect
match between $got and $expect. All hash fields must be specified,
all array items must be present, etc. All
non-scalar/hash/array/regex references must be identical (same
memory address). Scalar, hash and array references will be traversed
and compared. Regex references will be compared to see if they have
the same pattern.
is(
$some_hash,
{a => 1, b => 2, c => 3},
"The hash we got matches our expectations"
);
The only exception to strictness is when it is given an $expect
object that was built from a specification, in which case the
specification determines the strictness. Strictness only applies to
literal values/references that are provided and converted to a
specification for you.
is(
$some_hash,
hash { # Note: the hash function is not exported by default
field a => 1;
field b => match(qr/\A[0-9]+\z/); # Note: The match function is not exported by default
# Don't care about other fields.
},
"The hash comparison is not strict"
);
This works for both deep and shallow structures. For instance you
can use this to compare two strings:
is('foo', 'foo', "strings match");
Note: This is not the tool to use if you want to check if two
references are the same exact reference, use ref_is() from the
Test2::Tools::Ref plugin instead. Most of the time this will work as
well, however there are problems if your reference contains a cycle
and refers back to itself at some point. If this happens, an
exception will be thrown to break an otherwise infinite recursion.
Note: Non-reference values will be compared as strings using "eq",
so that means strings '2.0' and '2' will not match, but numeric 2.0
and 2 will, since they are both stringified to '2'.
$bool = isnt($got, $expect)
$bool = isnt($got, $expect, $name)
$bool = isnt($got, $expect, $name, @diag)
Opposite of is(). Does all the same checks, but passes when there is
a mismatch.
$bool = like($got, $expect)
$bool = like($got, $expect, $name)
$bool = like($got, $expect, $name, @diag)
$got is the data structure you want to check. $expect is what you
want $got to look like. $name is an optional name for the test.
@diag is optional diagnostics messages that will be printed to
STDERR in event of failure, they will not be displayed when the
comparison is successful. The boolean true/false result of the
comparison is returned.
This is the relaxed checker. This will ignore hash keys or array
indexes that you do not actually specify in your $expect structure.
In addition regex and sub references will be used as validators. If
you provide a regex using "qr/.../", the regex itself will be used
to validate the corresponding value in the $got structure. The same
is true for coderefs, the value is passed in as the first argument
(and in $_) and the sub should return a boolean value. In this tool
regexes will stringify the thing they are checking.
like(
$some_hash,
{a => 1, b => qr/\A[0-9]+\z/},
"'a' is 1, 'b' is an integer, we don't care about other fields"
);
This works for both deep and shallow structures. For instance you
can use this to compare two strings:
like('foo bar', qr/^foo/, "string matches the pattern");
$bool = unlike($got, $expect)
$bool = unlike($got, $expect, $name)
$bool = unlike($got, $expect, $name, @diag)
Opposite of like(). Does all the same checks, but passes when there
is a mismatch.
The is(), isnt(), like(), and unlike() functions can be made to dump
$got using Data::Dumper when tests fail by setting the "T2_AUTO_DUMP"
environment variable to "1". (Alternatively, "T2_AUTO_DUMP" can be set
to the name of a Perl module providing a compatible Dump() method.) The
"T2_AUTO_DEPARSE" environment variable can be used to enable
Data::Dumper's deparsing of coderefs.
QUICK CHECKS
Note: None of these are exported by default. You need to request them.
Quick checks are a way to quickly generate a common value specification.
These can be used in structures passed into "is" and "like" through the
$expect argument.
Example:
is($foo, T(), '$foo has a true value');
$check = T()
This verifies that the value in the corresponding $got structure is
true, any true value will do.
is($foo, T(), '$foo has a true value');
is(
{ a => 'xxx' },
{ a => T() },
"The 'a' key is true"
);
$check = F()
This verifies that the value in the corresponding $got structure is
false, any false value will do, but the value must exist.
is($foo, F(), '$foo has a false value');
is(
{ a => 0 },
{ a => F() },
"The 'a' key is false"
);
It is important to note that a nonexistent value does not count as
false. This check will generate a failing test result:
is(
{ a => 1 },
{ a => 1, b => F() },
"The 'b' key is false"
);
This will produce the following output:
not ok 1 - The b key is false
# Failed test "The 'b' key is false"
# at some_file.t line 10.
# +------+------------------+-------+---------+
# | PATH | GOT | OP | CHECK |
# +------+------------------+-------+---------+
# | {b} | <DOES NOT EXIST> | FALSE | FALSE() |
# +------+------------------+-------+---------+
In Perl, you can have behavior that is different for a missing key
vs. a false key, so it was decided not to count a completely absent
value as false. See the DNE() shortcut below for checking that a
field is missing.
If you want to check for false and/or DNE use the FDNE() check.
$check = D()
This is to verify that the value in the $got structure is defined.
Any value other than "undef" will pass.
This will pass:
is('foo', D(), 'foo is defined');
This will fail:
is(undef, D(), 'foo is defined');
$check = U()
This is to verify that the value in the $got structure is undefined.
This will pass:
is(undef, U(), 'not defined');
This will fail:
is('foo', U(), 'not defined');
$check = DF()
This is to verify that the value in the $got structure is defined
but false. Any false value other than "undef" will pass.
This will pass:
is(0, DF(), 'foo is defined but false');
These will fail:
is(undef, DF(), 'foo is defined but false');
is(1, DF(), 'foo is defined but false');
$check = E()
This can be used to check that a value exists. This is useful to
check that an array has more values, or to check that a key exists
in a hash, even if the value is undefined.
These pass:
is(['a', 'b', undef], ['a', 'b', E()], "There is a third item in the array");
is({a => 1, b => 2}, {a => 1, b => E()}, "The 'b' key exists in the hash");
These will fail:
is(['a', 'b'], ['a', 'b', E()], "Third item exists");
is({a => 1}, {a => 1, b => E()}, "'b' key exists");
$check = DNE()
This can be used to check that no value exists. This is useful to
check the end bound of an array, or to check that a key does not
exist in a hash.
These pass:
is(['a', 'b'], ['a', 'b', DNE()], "There is no third item in the array");
is({a => 1}, {a => 1, b => DNE()}, "The 'b' key does not exist in the hash");
These will fail:
is(['a', 'b', 'c'], ['a', 'b', DNE()], "No third item");
is({a => 1, b => 2}, {a => 1, b => DNE()}, "No 'b' key");
$check = FDNE()
This is a combination of F() and DNE(). This will pass for a false
value, or a nonexistent value.
$check = L()
This is to verify that the value in the $got structure is defined
and has length. Any value other than "undef" or the empty string
will pass (including references).
These will pass:
is('foo', L(), 'value is defined and has length');
is([], L(), 'value is defined and has length');
These will fail:
is(undef, L(), 'value is defined and has length');
is('', L(), 'value is defined and has length');
VALUE SPECIFICATIONS
Note: None of these are exported by default. You need to request them.
$check = string "..."
Verify that the value matches the given string using the "eq"
operator.
$check = !string "..."
Verify that the value does not match the given string using the "ne"
operator.
$check = number ...;
Verify that the value matches the given number using the "=="
operator.
$check = !number ...;
Verify that the value does not match the given number using the "!="
operator.
$check = number_lt ...;
$check = number_le ...;
$check = number_ge ...;
$check = number_gt ...;
Verify that the value is less than, less than or equal to, greater
than or equal to, or greater than the given number.
$check = float ...;
Verify that the value is approximately equal to the given number.
If a 'precision' parameter is specified, both operands will be
rounded to 'precision' number of fractional decimal digits and
compared with "eq".
is($near_val, float($val, precision => 4), "Near 4 decimal digits");
Otherwise, the check will be made within a range of +/- 'tolerance',
with a default 'tolerance' of 1e-08.
is( $near_val, float($val, tolerance => 0.01), "Almost there...");
See also "within" and "rounded".
$check = !float ...;
Verify that the value is not approximately equal to the given
number.
If a 'precision' parameter is specified, both operands will be
rounded to 'precision' number of fractional decimal digits and
compared with "eq".
Otherwise, the check will be made within a range of +/- 'tolerance',
with a default 'tolerance' of 1e-08.
See also "!within" and "!rounded".
$check = within($num, $tolerance);
Verify that the value approximately matches the given number, within
a range of +/- $tolerance. Compared using the "==" operator.
$tolerance is optional and defaults to 1e-08.
$check = !within($num, $tolerance);
Verify that the value does not approximately match the given number
within a range of +/- $tolerance. Compared using the "!=" operator.
$tolerance is optional and defaults to 1e-08.
$check = rounded($num, $precision);
Verify that the value approximately matches the given number, when
both are rounded to $precision number of fractional digits. Compared
using the "eq" operator.
$check = !rounded($num, $precision);
Verify that the value does not approximately match the given number,
when both are rounded to $precision number of fractional digits.
Compared using the "ne" operator.
$check = bool ...;
Verify the value has the same boolean value as the given argument
(XNOR).
$check = !bool ...;
Verify the value has a different boolean value from the given
argument (XOR).
$check = check_isa ...;
Verify the value is an instance of the given class name.
$check = !check_isa ...;
Verify the value is not an instance of the given class name.
$check = match qr/.../
$check = !mismatch qr/.../
Verify that the value matches the regex pattern. This form of
pattern check will NOT stringify references being checked.
Note: "!mismatch()" is documented for completion, please do not use
it.
$check = !match qr/.../
$check = mismatch qr/.../
Verify that the value does not match the regex pattern. This form of
pattern check will NOT stringify references being checked.
Note: mismatch() was created before overloading of "!" for match()
was a thing.
$check = validator(sub{ ... })
$check = validator($NAME => sub{ ... })
$check = validator($OP, $NAME, sub{ ... })
The coderef is the only required argument. The coderef should check
that the value is what you expect and return a boolean true or
false. Optionally, you can specify a name and operator that are used
in diagnostics. They are also provided to the sub itself as named
parameters.
Check the value using this sub. The sub gets the value in $_, and it
receives the value and several other items as named parameters.
my $check = validator(sub {
my %params = @_;
# These both work:
my $got = $_;
my $got = $params{got};
# Check if a value exists at all
my $exists = $params{exists}
# What $OP (if any) did we specify when creating the validator
my $operator = $params{operator};
# What name (if any) did we specify when creating the validator
my $name = $params{name};
...
return $bool;
}
$check = exact_ref($ref)
Check that the value is exactly the same reference as the one
provided.
SET BUILDERS
Note: None of these are exported by default. You need to request them.
my $check = check_set($check1, $check2, ...)
Check that the value matches ALL of the specified checks.
my $check = in_set($check1, $check2, ...)
Check that the value matches ONE OR MORE of the specified checks.
not_in_set($check1, $check2, ...)
Check that the value DOES NOT match ANY of the specified checks.
check $thing
Check that the value matches the specified thing.
HASH BUILDER
Note: None of these are exported by default. You need to request them.
$check = hash {
field foo => 1;
field bar => 2;
# Ensure the 'baz' keys does not even exist in the hash.
field baz => DNE();
# Ensure the key exists, but is set to undef
field bat => undef;
# Any check can be used
field boo => $check;
# Set checks that apply to all keys or values. Can be done multiple
# times, and each call can define multiple checks, all will be run.
all_vals match qr/a/, match qr/b/; # All values must have an 'a' and a 'b'
all_keys match qr/x/; # All keys must have an 'x'
...
end(); # optional, enforces that no other keys are present.
};
$check = hash { ... }
This is used to define a hash check.
field $NAME => $VAL
field $NAME => $CHECK
Specify a field check. This will check the hash key specified by
$NAME and ensure it matches the value in $VAL. You can put any valid
check in $VAL, such as the result of another call to "array { ...
}", DNE(), etc.
Note: This function can only be used inside a hash builder sub, and
must be called in void context.
all_keys($CHECK1, $CHECK2, ...)
Add checks that apply to all keys. You can put this anywhere in the
hash block, and can call it any number of times with any number of
arguments.
all_vals($CHECK1, $CHECK2, ...)
all_values($CHECK1, $CHECK2, ...)
Add checks that apply to all values. You can put this anywhere in
the hash block, and can call it any number of times with any number
of arguments.
end()
Enforce that no keys are found in the hash other than those
specified. This is essentially the "use strict" of a hash check.
This can be used anywhere in the hash builder, though typically it
is placed at the end.
etc()
Ignore any extra keys found in the hash. This is the opposite of
end(). This can be used anywhere in the hash builder, though
typically it is placed at the end.
DNE()
This is a handy check that can be used with field() to ensure that a
field (D)oes (N)ot (E)xist.
field foo => DNE();
ARRAY BUILDER
Note: None of these are exported by default. You need to request them.
$check = array {
# Uses the next index, in this case index 0;
item 'a';
# Gets index 1 automatically
item 'b';
# Specify the index
item 2 => 'c';
# We skipped index 3, which means we don't care what it is.
item 4 => 'e';
# Gets index 5.
item 'f';
# Remove any REMAINING items that contain 0-9.
filter_items { grep {!m/[0-9]/} @_ };
# Set checks that apply to all items. Can be done multiple times, and
# each call can define multiple checks, all will be run.
all_items match qr/a/, match qr/b/;
all_items match qr/x/;
# Of the remaining items (after the filter is applied) the next one
# (which is now index 6) should be 'g'.
item 6 => 'g';
item 7 => DNE; # Ensure index 7 does not exist.
end(); # Ensure no other indexes exist.
};
$check = array { ... }
item $VAL
item $CHECK
item $IDX, $VAL
item $IDX, $CHECK
Add an expected item to the array. If $IDX is not specified it will
automatically calculate it based on the last item added. You can
skip indexes, which means you do not want them to be checked.
You can provide any value to check in $VAL, or you can provide any
valid check object.
Note: Items MUST be added in order.
Note: This function can only be used inside an array, bag or subset
builder sub, and must be called in void context.
filter_items { my @remaining = @_; ...; return @filtered }
This function adds a filter, all items remaining in the array from
the point the filter is reached will be passed into the filter sub
as arguments, the sub should return only the items that should be
checked.
Note: This function can only be used inside an array builder sub,
and must be called in void context.
all_items($CHECK1, $CHECK2, ...)
Add checks that apply to all items. You can put this anywhere in the
array block, and can call it any number of times with any number of
arguments.
end()
Enforce that there are no indexes after the last one specified. This
will not force checking of skipped indexes.
etc()
Ignore any extra items found in the array. This is the opposite of
end(). This can be used anywhere in the array builder, though
typically it is placed at the end.
DNE()
This is a handy check that can be used with item() to ensure that an
index (D)oes (N)ot (E)xist.
item 5 => DNE();
BAG BUILDER
Note: None of these are exported by default. You need to request them.
$check = bag {
item 'a';
item 'b';
end(); # Ensure no other elements exist.
};
A bag is like an array, but we don't care about the order of the items.
In the example, $check would match both "['a','b']" and "['b','a']".
$check = bag { ... }
item $VAL
item $CHECK
Add an expected item to the bag.
You can provide any value to check in $VAL, or you can provide any
valid check object.
Note: This function can only be used inside an array, bag or subset
builder sub, and must be called in void context.
all_items($CHECK1, $CHECK2, ...)
Add checks that apply to all items. You can put this anywhere in the
bag block, and can call it any number of times with any number of
arguments.
end()
Enforce that there are no more items after the last one specified.
etc()
Ignore any extra items found in the array. This is the opposite of
end(). This can be used anywhere in the bag builder, though
typically it is placed at the end.
ORDERED SUBSET BUILDER
Note: None of these are exported by default. You need to request them.
$check = subset {
item 'a';
item 'b';
item 'c';
# Doesn't matter if the array has 'd', the check will skip past any
# unknown items until it finds the next one in our subset.
item 'e';
item 'f';
};
$check = subset { ... }
item $VAL
item $CHECK
Add an expected item to the subset.
You can provide any value to check in $VAL, or you can provide any
valid check object.
Note: Items MUST be added in order.
Note: This function can only be used inside an array, bag or subset
builder sub, and must be called in void context.
META BUILDER
Note: None of these are exported by default. You need to request them.
my $check = meta {
prop blessed => 'My::Module'; # Ensure value is blessed as our package
prop reftype => 'HASH'; # Ensure value is a blessed hash
prop isa => 'My::Base'; # Ensure value is an instance of our class
prop size => 4; # Check the number of hash keys
prop this => ...; # Check the item itself
};
meta { ... }
meta_check { ... }
Build a meta check. If you are using Moose then the meta() function
would conflict with the one exported by Moose, in such cases
meta_check() is available. Neither is exported by default.
prop $NAME => $VAL
prop $NAME => $CHECK
Check the property specified by $name against the value or check.
Valid properties are:
'blessed'
What package (if any) the thing is blessed as.
'reftype'
Reference type (if any) the thing is.
'isa'
What class the thing is an instance of.
'this'
The thing itself.
'size'
For array references this returns the number of elements. For
hashes this returns the number of keys. For everything else this
returns undef.
OBJECT BUILDER
Note: None of these are exported by default. You need to request them.
my $check = object {
call foo => 1; # Call the 'foo' method, check the result.
# Call the specified sub-ref as a method on the object, check the
# result. This is useful for wrapping methods that return multiple
# values.
call sub { [ shift->get_list ] } => [...];
# This can be used to ensure a method does not exist.
call nope => DNE();
# Check the hash key 'foo' of the underlying reference, this only works
# on blessed hashes.
field foo => 1;
# Check the value of index 4 on the underlying reference, this only
# works on blessed arrays.
item 4 => 'foo';
# Check the meta-property 'blessed' of the object.
prop blessed => 'My::Module';
# Check if the object is an instance of the specified class.
prop isa => 'My::Base';
# Ensure only the specified hash keys or array indexes are present in
# the underlying hash. Has no effect on meta-property checks or method
# checks.
end();
};
$check = object { ... }
Specify an object check for use in comparisons.
call $METHOD_NAME => $RESULT
call $METHOD_NAME => $CHECK
call [$METHOD_NAME, @METHOD_ARGS] => $RESULT
call [$METHOD_NAME, @METHOD_ARGS] => $CHECK
call sub { ... }, $RESULT
call sub { ... }, $CHECK
Call the specified method (or coderef) and verify the result. If you
pass an arrayref, the first element must be the method name, the
others are the arguments it will be called with.
The coderef form is useful if you need to do something more complex.
my $ref = sub {
local $SOME::GLOBAL::THING = 3;
return [shift->get_values_for('thing')];
};
call $ref => ...;
call_list $METHOD_NAME => $RESULT
call_list $METHOD_NAME => $CHECK
call_list [$METHOD_NAME, @METHOD_ARGS] => $RESULT
call_list [$METHOD_NAME, @METHOD_ARGS] => $CHECK
call_list sub { ... }, $RESULT
call_list sub { ... }, $CHECK
Same as "call", but the method is invoked in list context, and the
result is always an arrayref.
call_list get_items => [ ... ];
call_hash $METHOD_NAME => $RESULT
call_hash $METHOD_NAME => $CHECK
call_hash [$METHOD_NAME, @METHOD_ARGS] => $RESULT
call_hash [$METHOD_NAME, @METHOD_ARGS] => $CHECK
call_hash sub { ... }, $RESULT
call_hash sub { ... }, $CHECK
Same as "call", but the method is invoked in list context, and the
result is always a hashref. This will warn if the method returns an
odd number of values.
call_hash get_items => { ... };
field $NAME => $VAL
Works just like it does for hash checks.
item $VAL
item $IDX, $VAL
Works just like it does for array checks.
prop $NAME => $VAL
prop $NAME => $CHECK
Check the property specified by $name against the value or check.
Valid properties are:
'blessed'
What package (if any) the thing is blessed as.
'reftype'
Reference type (if any) the thing is.
'isa'
What class the thing is an instance of.
'this'
The thing itself.
'size'
For array references this returns the number of elements. For
hashes this returns the number of keys. For everything else this
returns undef.
DNE()
Can be used with "item", or "field" to ensure the hash field or
array index does not exist. Can also be used with "call" to ensure a
method does not exist.
end()
Turn on strict array/hash checking, ensuring that no extra
keys/indexes are present.
etc()
Ignore any extra items found in the hash/array. This is the opposite
of end(). This can be used anywhere in the builder, though
typically it is placed at the end.
EVENT BUILDERS
Note: None of these are exported by default. You need to request them.
Check that we got an event of a specified type:
my $check = event 'Ok';
Check for details about the event:
my $check = event Ok => sub {
# Check for a failure
call pass => 0;
# Effective pass after TODO/SKIP are accounted for.
call effective_pass => 1;
# Check the diagnostics
call diag => [ match qr/Failed test foo/ ];
# Check the file the event reports to
prop file => 'foo.t';
# Check the line number the event reports to
prop line => '42';
# You can check the todo/skip values as well:
prop skip => 'broken';
prop todo => 'fixme';
# Thread-id and process-id where event was generated
prop tid => 123;
prop pid => 123;
};
You can also provide a fully qualified event package with the '+'
prefix:
my $check = event '+My::Event' => sub { ... }
You can also provide a hashref instead of a sub to directly check hash
values of the event:
my $check = event Ok => { pass => 1, ... };
USE IN OTHER BUILDERS
You can use these all in other builders, simply use them in void context
to have their value(s) appended to the build.
my $check = array {
event Ok => { ... };
event Note => { ... };
fail_events Ok => { pass => 0 };
# Get a Diag for free.
};
SPECIFICS
$check = event $TYPE;
$check = event $TYPE => sub { ... };
$check = event $TYPE => { ... };
This works just like an object builder. In addition to supporting
everything the object check supports, you also have to specify the
event type, and many extra meta-properties are available.
Extra properties are:
'file'
File name to which the event reports (for use in diagnostics).
'line'
Line number to which the event reports (for use in diagnostics).
'package'
Package to which the event reports (for use in diagnostics).
'subname'
Sub that was called to generate the event (example: ok()).
'skip'
Set to the skip value if the result was generated by skipping
tests.
'todo'
Set to the todo value if TODO was set when the event was
generated.
'trace'
The "at file foo.t line 42" string that will be used in
diagnostics.
'tid'
Thread ID in which the event was generated.
'pid'
Process ID in which the event was generated.
NOTE: Event checks have an implicit etc() added. This means you need
to use end() if you want to fail on unexpected hash keys or array
indexes. This implicit etc() extends to all forms, including
builder, hashref, and no argument.
@checks = fail_events $TYPE;
@checks = fail_events $TYPE => sub { ... };
@checks = fail_events $TYPE => { ... };
Just like event() documented above. The difference is that this
produces two events, the one you specify, and a "Diag" after it.
There are no extra checks in the Diag.
Use this to validate a simple failure where you do not want to be
bothered with the default diagnostics. It only adds a single Diag
check, so if your failure has custom diagnostics you will need to
add checks for them.
