Gem5Fixture is used to define a fixture for building the gem5 binary. Most tests are expected to define their own Gem5Fixture, however, as some might depend on the same binary (e.g., ./build/ARM/gem5.opt), they will try to re-define a fixture for the same target. This patchset changes Gem5Fixture to derive from UniqueFixture. In addition, this patchset changes the way global fixtures are discovered to work with the new Gem5Fixture class. Instead of enumerating them when test definitions are loaded, we do so after the tests have been filtered according to specified tags (e.g., include opt variant, exclude fast, debug variants).

Base Class for a test Fixture.
|
|
|
|
Fixtures are items which possibly require setup and/or tearing down after
|
|
a TestCase, TestSuite, or the Library has completed.
|
|
|
|
Fixtures are the prefered method of carrying incremental results or
|
|
variables between TestCases in TestSuites. (Rather than using globals.)
|
|
Using fixtures rather than globals ensures that state will be maintained
|
|
when executing tests in parallel.
|
|
|
|
.. note:: In order for Fixtures to be enumerated by the test system this
|
|
class' :code:`__new__` method must be called.
