"""Manages and runs tests from the current working directory.
|
|
|
|
This will traverse the current working directory and look for python files that
|
|
contain subclasses of SpirvTest.
|
|
|
|
If a class has an @inside_spirv_testsuite decorator, an instance of that
|
|
class will be created and serve as a test case in that testsuite. The test
|
|
case is then run by the following steps:
|
|
|
|
1. A temporary directory will be created.
|
|
2. The spirv_args member variable will be inspected and all placeholders in it
|
|
will be expanded by calling instantiate_for_spirv_args() on placeholders.
|
|
The transformed list elements are then supplied as arguments to the spirv-*
|
|
tool under test.
|
|
3. If the environment member variable exists, its write() method will be
|
|
invoked.
|
|
4. All expected_* member variables will be inspected and all placeholders in
|
|
them will be expanded by calling instantiate_for_expectation() on those
|
|
placeholders. After placeholder expansion, if the expected_* variable is
|
|
a list, its element will be joined together with '' to form a single
|
|
string. These expected_* variables are to be used by the check_*() methods.
|
|
5. The spirv-* tool will be run with the arguments supplied in spirv_args.
|
|
6. All check_*() member methods will be called by supplying a TestStatus as
|
|
argument. Each check_*() method is expected to return a (Success, Message)
|
|
pair where Success is a boolean indicating success and Message is an error
|
|
message.
|
|
7. If any check_*() method fails, the error message is output and the
|
|
current test case fails.
|
|
|
|
If --leave-output was not specified, all temporary files and directories will
|
|
be deleted.
