The Software Verification Plan mentions the verification methods and their identifier. The mentions of "TestType" is basically representing these terms, but is using a different language.
Some examples, how things are currently used:
RecordProperty("TestType", "Requirements-based test");
RecordProperty("TestType", "Interface test");
::testing::Test::RecordProperty("TestType", "Verification of control flow");
This should be changed according to process:
RecordProperty("TestType", "requirements-based");
RecordProperty("TestType", "interface-test");
::testing::Test::RecordProperty("TestType", "control-flow-analysis");
