NAME
Test::Needs - Skip tests when modules not available
SYNOPSIS
# need one module
use Test::Needs 'Some::Module';
# need multiple modules
use Test::Needs 'Some::Module', 'Some::Other::Module';
# need a given version of a module
use Test::Needs {
'Some::Module' => '1.005',
};
# check later
use Test::Needs;
test_needs 'Some::Module';
# skips remainder of subtest
use Test::More;
use Test::Needs;
subtest 'my subtest' => sub {
test_needs 'Some::Module';
...
};
# check perl version
use Test::Needs { perl => 5.020 };
DESCRIPTION
Skip test scripts if modules are not available. The requested modules will be loaded, and optionally have their versions checked. If the module is missing, the test script will be skipped. Modules that are found but fail to compile will exit with an error rather than skip.
If used in a subtest, the remainder of the subtest will be skipped.
Skipping will work even if some tests have already been run, or if a plan has been declared.
Versions are checked via a $module->VERSION($wanted_version)
call. Versions must be provided in a format that will be accepted. No extra processing is done on them.
If perl
is used as a module, the version is checked against the running perl version ($]). The version can be specified as a number, dotted-decimal string, v-string, or version object.
If the RELEASE_TESTING
environment variable is set, the tests will fail rather than skip. Subtests will be aborted, but the test script will continue running after that point.
EXPORTS
test_needs
Has the same interface as when using Test::Needs in a use
.
SEE ALSO
- Test::Requires
-
A similar module, with some important differences. Test::Requires will act as a
use
statement (despite its name), calling the import sub. UnderRELEASE_TESTING
, it will BAIL_OUT if a module fails to load rather than using a normal test fail. It also doesn't distinguish between missing modules and broken modules. - Test2::Require::Module
-
Part of the Test2 ecosystem. Only supports running as a
use
command to skip an entire plan. - Test2::Require::Perl
-
Part of the Test2 ecosystem. Only supports running as a
use
command to skip an entire plan. Checks perl versions. - Test::If
-
Acts as a
use
statement. Only supports running as ause
command to skip an entire plan. Can skip based on subref results.
