1956843 - "./mach test <path to xpcshell test file> --profiler" should work

Status: RESOLVED FIXED

(Testing :: XPCShell Harness, enhancement)

Description

[Florian Quèze [:florian]]

Since bug 1628073, ./mach test <path to mochitests> --profiler opens a profiler tab in the default browser at the end of the test execution, which is very convenient to see what a test is doing, and debug failures.

Currently this doesn't work for xpcshell tests, and the best workaround is: MOZ_PROFILER_STARTUP=1 MOZ_PROFILER_SHUTDOWN="$(pwd)/xp.json" ./mach test <path to xpcshell test> ; samply load xp.json.

I think it would be easy to support xpcshell as well for the case of running a single test, which is what is the most needed to help debugging a test failure. Profiling multiple xpcshell tests requires more effort (as we would need to generate multiple separate profile files, and merge them somehow).
