I often forget to add newly created tests to the testng.xml, which is used in our TeamCity build, and by the time I realize that they don’t run something is surely went wrong. What a bummer! Not any more, fortunately — IntelliJ IDEA makes sure no tests are missing. All it takes is to enable the Undeclared test inspection under TestNG in the Errors section of the Settings dialog.
