Protected Member Functions | |
| bool | IsGoldenTestSuite () const override |
| This method is overridden on a test suite basis and establishes whether a given set of tests is intended to generate goldens. | |
 Protected Member Functions inherited from impeller::Playground | |
| void | TearDownContextData () |
| virtual void | EnsureContextIsUnique () |
| Make sure that when the context is later created that it will not be shared with any other playgrounds. | |
| bool | PlatformSupportsWideGamutTests () const |
| Returns true if the platform can support wide gamuts. | |
| bool | RenderingSupportsMSAA () const |
| Returns true if the rendering path supports MSAA rendering. | |
| SampleCount | GetDefaultSampleCount () const |
| Returns the default sample count of the rendering path. | |
| virtual bool | EnsureContextSupportsWideGamut () |
| Make sure that when the context is later created that it will support wide gamuts if the platform supports it. Returns whether the platform supports wide gamut. | |
| const PlaygroundSwitches & | GetSwitches () const |
| Return an unmodifiable reference to the current switches. The switches might change at the start of a test as it has a brief opportunity to call any of the Ensure* methods that define the environment it expects, but should be stable by the time any subsequent methods that might perform work are called. | |

This method is overridden on a test suite basis and establishes whether a given set of tests is intended to generate goldens.
The return value of this method is used to set the default value of |PlaygroundShouldWriteGoldenImage|, but an individual test is still allowed to enable a golden image by calling |SetEnableWriteGolden|.
Reimplemented from impeller::PlaygroundTest.
