internal/xds/clients/grpctransport/grpc_transport_test.go:185–253

TestBuild_Failure verifies that the Builder returns error when incorrect ServerIdentifier is provided. It covers the following scenarios: - ServerURI is empty. - Extensions is nil. - Extensions is not ServerIdentifierExtension. - Credentials are nil.

(t *testing.T)

// - Extensions is not ServerIdentifierExtension.
// - Credentials are nil.
