1268496 - mach try should not assume a test path is always in the same job

Status: NEW

(Developer Infrastructure :: Try, defect)

Description

[Andreas Tolfsen ❲:ato❳]

When using `./mach try … PATH` producing a try syntax of something like "try: … --try-test-paths web-platform-tests:PATH", it should not assume that this test is always batched in the same job across platforms.

Example mach command:

    ./mach try -b do -p win64,linux64,macosx64 testing/web-platform/tests/navigation-timing

Resulting try syntax:

    try: -b do -p win64,linux64,macosx64 -u web-platform-tests-1 -t none --try-test-paths web-platform-tests:testing/web-platform/tests/navigation-timing

This causes the W(1) job to get triggered, which works fine on opt builds, but not on debug because the test is located in W(5) on Linux debug and W(6) on OS X and Windows debug.

Example try run:
