 # gn_isolate_map.pyl - A mapping of Ninja build target names to GN labels and
 # test type classifications for the tests that are run on the bots.
 #
 # This mapping is used by MB so that we can uniformly refer to test binaries
 # by their Ninja target names in the recipes and not need to worry about how
 # they are referred to in GN or GYP specifically (the GYP target name is pretty
 # much always the same as the Ninja target name, since GYP target names are not
 # hierarchical).
 #
-# The 'type' field is used to determine what the command line for the test
+# The "label" field specifies the matching GN label for the given ninja
+# target.
+#
+# The "type" field is used to determine what the command line for the test
 # needs to be; valid values are:
 #
-# "windowed_test_launcher"
-# : the test is a gtest-based test that uses the 'brave-new-test-launcher'
-#   from //base/test:test_support and needs to run under Xvfb if run on
-#   an X11-based platform (use_x11=true).
+#  "windowed_test_launcher"
+#  : the test is a gtest-based test that uses the "brave-new-test-launcher"
+#    from //base/test:test_support and needs to run under Xvfb if run on
+#    an X11-based platform (use_x11=true).
 #  "console_test_launcher"
-#  : the test is a gtest-based test that uses the 'brave-new-test-launcher'
+#  : the test is a gtest-based test that uses the "brave-new-test-launcher"
 #    from //base/test:test_support but does not need Xvfb.
 #  "gpu_browser_test"
 #  : the test is a subset of the browser_tests that will be run against
 #    a real GPU.
 #  "raw"
 #  : the test is a standalone executable; it may take an optional list of
-#    command line arguments in the 'args' field, but otherwise needs no
+#    command line arguments in the "args" field, but otherwise needs no
 #    extra files or special handling.
+#  "script"
+#  : the test is a python script; the path to the script is specified in
+#    the "script" field.
 #  "unknown"
 #  : (the default), which indicates that we don't know what the command line
 #    needs to be (this is a fatal error).
+#
+# The optional "executable" field can be used to override the name
+# of the binary to run. If the field is not specified, the binary
+# name will be assumed to be the same as the ninja build target name.
+# On Windows, ".exe" will be automatically appended if need be, so
+# the executable name (and target name) should not contain an ".exe".
+#
+# The optional "args" field can be used to append extra command line
+# args onto the command line determined by the "type". If not specified,
+# it defaults to an empty list (no extra args).
+#
+# The optional "label_type" field can be used in conjunction with
+# "type" == "console_test_launcher" or "type" == "windowed_test_launcher"
+# to indicate that even though the command line
+# to use follows the test_launcher patterns, the actual GN label refers
+# to a different type of thing (usually a "group") and so MB can find
+# the generated runtime files in the right place. This is used, for
+# example, in content_site_isolation_browsertests .
+#
+# The optional "script" field is used when "type" == "script", and
+# specifies the GN path to the corresponding python file, e.g.
+# "//testing/scripts/foo.py".
