FYI: Another mechanism to add output messages for tests that fail, instead of cout, is use the gtest feature.

EXPECT_TRUE(<put condition here>) << <put your log message here>;

This way, you only output that error message if the test assertion fails.

You can also use: GTEST_LOG_INFO. We have a few places in test that do that already.

In cases like this, where you want to fail a test if it reaches this point, rather than using EXPECT_TRUE(false), you can see GTEST_FAIL with an output message appended to it

Here are a couple example usages of that:

azure-sdk-for-cpp/sdk/eventhubs/azure-messaging-eventhubs/test/ut/eventhubs_admin_client_test.cpp

Lines 68 to 69 in d609c00

	GTEST_LOG_(ERROR) << "Response: " << bodyAsString;
	GTEST_FAIL();

azure-sdk-for-cpp/sdk/identity/azure-identity/test/ut/azure_pipelines_credential_test.cpp

Line 573 in d609c00

GTEST_FAIL() << "GetToken should have thrown an exception due to an invalid tenant ID.";
