Launch browsers with redirecting files (#2703) The test runner creates a secret key used for communication with the browsers to prevent third party processes from connecting as if they were running test suites, but this key is current leaking through the command arguments when starting the browser process. We are already using temp directories which should prevent external reads and the safari browser launcher already used this pattern. Extend the `redirect.html` pattern to chromium and firefox browsers.
Welcome! package:test is the standard testing library for Dart and Flutter. If you have questions about Dart testing, please see the docs for package:test. package:test_api and package:test_core are implementation details and generally not user-facing.
package:checks is a relatively new library for expressing test expectations. It's a more modern version of package:matcher and features a literate API.
