// This file consists of tests for COEP reporting. The tests make COEP
// violations and see whether reports are sent to the network as specified.
// We only have basic tests in this file - one for each kind of reports,
// because we can also test the reporting functionality with ReportingObserver,
// and that way is faster, easier to debug, and less flaky.
//
// For more detailed tests and tests with workers, see tests in other files
// such as
// - reporting-navigation.https.html
// - reporting-subresource-corp.https.html
// - cache-storage-reporting*.https.html
