Test filter files

Summary

This directory contains files that list tests that are not yet ready to run in a particular mode. For example - the site-per-process.browser_tests.filter file lists tests that should be excluded when running browser_tests in --site-per-process mode.

File syntax

Contents of test filter files follow the syntax below:

  • Empty lines are ignored
  • Lines starting with the ‘#’ character are treated as comments and ignored.
  • All other lines specify a single test name pattern.
    • Negative patterns: Patterns prefixed with the ‘-’ character specify tests to exclude from a test run.
    • Positive patterns: All other patterns specify tests to include in a test run.

A test will be executed if and only if it matches any of the positive patterns but does not match any of the negative patterns (please see documentation of --gtest_filter for more details and examples).

Please see [https://crbug.com/587527] for discussion how “positive” and “negative” test patterns should be combined in presence of both the --gtest_filter and the --test-launcher-filter-file command line flags.

Example test filter file for excluding a set of tests:

# crbug.com/417518: Get tests working w/ --site-per-process
-BrowserTest.OtherRedirectsDontForkProcess
-ChromeRenderProcessHostTest.*
-ReferrerPolicyTest.HttpsRedirect

# crbug.com/448592: Get extension browsertests working w/ --site-per-process
-IsolatedAppTest.CookieIsolation
-IsolatedAppTest.CrossProcessClientRedirect
-IsolatedAppTest.IsolatedAppProcessModel
-IsolatedAppTest.SubresourceCookieIsolation

Usage

When running tests on desktop platforms, the test filter file can be specified using --test-launcher-filter-file command line flag. Example test invocation:

$ out/dbg/content_browsertests \
    --site-per-process \
    --test-launcher-filter-file=testing/buildbot/filters/site-per-process.content_browsertests.filter

When running tests on Android, the test filter file can be specified using --gtest-filter-file command line flag. Example test invocation:

$ out/android/bin/run_content_browsertests \
    --site-per-process \
    --gtest-filter-file=testing/buildbot/filters/site-per-process.content_browsertests.filter

Applicability

Test filter files described here are currently only supported for gtest-based tests.

For excluding layout tests when running with a particular command line flag, see third_party/WebKit/LayoutTests/FlagExpectations/README.txt.

Adding new test filter files

Please use the following conventions when naming the new file:

  • Please include the name of the test executable (e.g. content_browsertests).
  • Please use .filter suffix.
  • Feel free to add other relevant things into the file name (e.g. the mode the file applies to - for example site-per-process).

When adding a new file, please update //testing/buildbot/filters/BUILD.gn.
