Skipping Tests

Tests can be skipped conditionally using the skipif directive:

#VVT: skipif : python_expression

python_expression is evaluated and cast to a bool. If the result is True the test will be skipped. For example

#VVT: skipif : sys.platform == "Darwin"

would skip the test if run on Apple hardware.

When a test is skipped, vvtest reports the reason as "python_expression evaluated to True". The reason attribute can be supplied to provide a user defined reason for skipping. For example,

#VVT: skipif (reason=Test does not run on Apple hardware) : sys.platform == "Darwin"

Checking module availability

A test may be skipped if a module is not importable by using the importable function. importable(module_name) evaluates to True if module_name can be imported otherwise, False. For example,

#VVT: skipif : not importable("numpy")

would skip the test if numpy was not available.

Evaluation namespace

python_expression is evaluated in a minimal namespace consisting of the os module, sys module, and importable function.
