Test Transforms

Test descriptions specify how to run a unittest or talos run. They aim to describe this abstractly, although in many cases the unique nature of invocation on different platforms leaves a lot of specific behavior in the test description, divided by by-test-platform.

Test descriptions are validated to conform to the schema in taskcluster/gecko_taskgraph/transforms/test/__init__.py. This schema is extensively documented and is a the primary reference for anyone modifying tests.

The output of tests.py is a task description. Test dependencies are produced in the form of a dictionary mapping dependency name to task label.
