// SignedExchangeBrowserTestHelper helps writing browser tests for
// signed exchanges by:
// - Override signed exchange verification time epoch
// to that of the test SXGs in content/test/data/sxg.
// See kSignatureHeaderDate and kSignatureHeaderExpires for more details.
// - Setup URLLoaderInterceptor, which serves injected content via
// InstallUrlInterceptor.
//
// Typical usage would look like following:
//
// Installs a test mock certificate to the |mock_cert_verifier|
// to work with the test certificate used by the helper:
// SignedExchangeBrowserTestHlper helper;
// helper.InstallMockCert(mock_cert_verifier());
//
// Then installs a HTTP request interceptor for the cert chain
// for the same test mock certificate so that it can be fetched at
// the cert URL embedded in the test SXGs in content/test/data/sxg.
// helper.InstallMockCertChainInterceptor()
//
// Sets up HTTP request interceptors for the testing (e.g. SXGs,
// service worker resources).
// helper.InstallUrlInterceptor(
// GURL("https://test.example.org/scope/test.sxg"),
// "content/test/data/sxg/test.example.org_test.sxg");
