# Please keep builder names, builder configs and test definitions sorted.
# Builder names should be sorted alphabetically. Builder configs should have
# keys sorted in the alphabetical order except 'tests' key, which should always
# come last. Test definitions must have keys in the following order, but omit
# optional fields:
#  * name (required)
#  * suffix
#  * variant
#  * test_args
#  * shards
#  * swarming_dimensions
#  * swarming_task_attrs
#
# Please also format test definitions as a single line with ', ' separating
# fields, e.g.
#
#   {'name': 'v8testing', 'variant': 'extra', 'shards': 2}
#
# After formatting test definitions this way, please sort them alphabetically by
# test name. For all variants of the test with the same name, the
# least-qualified test (no variant, no test args) should come first. You may
# also deviate from the alphabetical order if necessary and group tests
# differently, but in this case please add a comment before each group and
# continue to sort tests using the rules above within each group.
