Skip tests when modules not available
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.
