+

+
+ 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",
