A few tests are examining code locations and looking af the resulting line numbers to verify that GoogleTest shows those to users correctly. Some of those locations change when clang-format is run. For those locations, I've wrapped portions in: // clang-format off ... // clang-format on There may be other locations that are currently not tickled by running clang-format.
