Since forever Jetpack tests in the Firefox trees have been run using our custom python CFX tool which is based on a fork of an ancient version of mozrunner. This causes us a number of problems. Keeping up with tree visibility rules is hard. Some features from newer versions of mozrunner like crash stack handling aren't available and our attempts to update to the newer mozbase have been blocked on trying to get some of our forked code accepted. It also makes it hard for Mozilla other developers to run our tests as CFX has a very different syntax to the other test suites.
We've started investigating switching away from CFX and instead using the python automation that the mochitests use. This would work somewhat similarly to browser-chrome tests, runtests.py will startup Firefox and overlay some XUL and JS on the main window from where we can run the existing JS parts of the Jetpack test suites. There are many benefits here. The runtests.py code is well used and known to be resilient. It supports things like screenshots on failures and crash stacks that Jetpack tests don't currently handle. We'll use manifest files like the other test suites so disabling tests per platform will be easy. Excellent mach integration will make running individual tests simple. It also makes it possible to use commonjs style tests elsewhere in the tree. Release engineering should find managing the Jetpack tests a lot easier as they behave just like other mochitests. My initial experiment last week shows that this will work. The first part of our tests (package tests) is running and passing on my local machine and I expect to have the add-on tests working this week. I wanted to give everyone a heads up about this work to give you all a chance to ask questions or raise objections. The changes to runtests and the build system are minimal, just adding support for new manifest types really but I will be needing reviews for those. We'll also have to make the buildbot changes to switch over to use these new tests but I expect that to be pretty straightforward. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
