# This is a .pyl, or "Python Literal", file. You can treat it just like a
# .json file, with the following exceptions:
# * all keys must be quoted (use single quotes, please);
# * comments are allowed, using '#' syntax; and
# * trailing commas are allowed.

# Exceptions to the common test suites can only include removal from
# particular bots, and modifications on particular bots. By design,
# it's not possible to add one-off tests to bots. Instead they have to
# be added to one of the test suites in test_suites.pyl.
#
# Note that if you are excluding with variants, you will need to exclude
# per variant, with the identifier appended to the test suite name.
# For example, if you have ios_chrome_ui_eg2tests_module with variant
# SIM_IPHONE_6S_14_0 (identifier = "iPhone 6s 14.0"), you
# must exclude with the test name as:
# "ios_chrome_ui_eg2tests_module_iPhone 6s 14.0"

# The goal is to drive the number of exceptions to zero, to make all
# the bots behave similarly.
