The existing Unity Test Tools package (see https://bitbucket.org/Unity-Technologies/unitytesttools/) contains a warning: "DEPRECATED This package will not be supported anymore. We introduced an integrated test runner in Unity 5.6 and will focus on developing it." The test tools package originally contained code for (a) unit testing, (b) integration testing and (c) assertions. Unit testing and assertions are now available in the Unity framework itself, but I cannot find anything for integration testing. So what is happening for integration testing in 5.6?
