test

Runs the unit tests for all of Gaffer’s python modules and libraries. These are run automatically as part of Gaffer’s build and review process, but it is useful to run them manually when developing for Gaffer or troubleshooting an installation.

Run all the tests :

gaffer test

Run all the tests for the scene module :

gaffer test GafferScene

Repeat a specific test 10 times :

gaffer test -repeat 10 GafferImageTest.ImageNodeTest.testCacheThreadSafety

-help

Prints names and descriptions of each parameter rather than running the application.

-threads

The maximum number of threads used for computation. The default value of zero causes the number of threads to be chosen automatically based on the available hardware.

-profileFileName

If this is specified, then the application is run using the cProfile profiling module, and the results saved to the file for later examination.

-testCases

A list of names of specific test cases to run. If unspecified then all test cases are run.

-repeat

The number of times to repeat the tests.

-performanceOnly

Skips tests that don’t compute performance metrics.

-outputFile

The name of a JSON file that the results are written to.

-previousOutputFile

The name of a JSON file containing the results of a previous test run. This will be used to detect and report performance regressions.

-stopOnFailure

Stops on the first failure, instead of running the remaining tests.
