I was unable to find tests from the given argument(s).

You should specify a test directory, filename, test suite name, or

abbreviation. If no arguments are given, there must be local file

changes and corresponding IMPACTED_TESTS annotations in moz.build

files relevant to those files.

It's possible my little brain doesn't know about the type of test you are

trying to execute. If you suspect this, please request support by filing

a bug at

https://bugzilla.mozilla.org/enter_bug.cgi?product=Testing&component=General.

mach test accepts arguments specifying which tests to run. Each argument

can be:

* The path to a test file

* A directory containing tests

* A test suite name

* An alias to a test suite name (codes used on TreeHerder)

If no input is provided, tests will be run based on files changed in

the local tree. Relevant tests, tags, or flavors are determined by

IMPACTED_TESTS annotations in moz.build files relevant to the

changed files.

When paths or directories are given, they are first resolved to test

files known to the build system.

If resolved tests belong to more than one test type/flavor/harness,

the harness for each relevant type/flavor will be invoked. e.g. if

you specify a directory with xpcshell and browser chrome mochitests,

both harnesses will be invoked.

"""Autotry is in beta, please file bugs blocking 1149670.

Push the current tree to try, with the specified syntax.

Build options, platforms and regression tests may be selected

using the usual try options (-b, -p and -u respectively). In

addition, tests in a given directory may be automatically

selected by passing that directory as a positional argument to the

command. For example:

mach try -b d -p linux64 dom testing/web-platform/tests/dom

would schedule a try run for linux64 debug consisting of all

tests under dom/ and testing/web-platform/tests/dom.

Test selection using positional arguments is available for

mochitests, reftests, xpcshell tests and web-platform-tests.

Tests may be also filtered by passing --tag to the command,

which will run only tests marked as having the specified

tags e.g.

mach try -b d -p win64 --tag media

would run all tests tagged 'media' on Windows 64.

If both positional arguments or tags and -u are supplied, the

suites in -u will be run in full. Where tests are selected by

positional argument they will be run in a single chunk.

If no build option is selected, both debug and opt will be

scheduled. If no platform is selected a default is taken from

the AUTOTRY_PLATFORM_HINT environment variable, if set.

The command requires either its own mercurial extension ("push-to-try",

installable from mach mercurial-setup) or a git repo using git-cinnabar

(available at https://github.com/glandium/git-cinnabar).
