One or more embodiments are described for function-message identifier oriented test case generation for seamlessly supporting continuous globalization verification testing in agile computer program product development. An example computer-implemented method includes identifying a newly added globalization function in a modified source code, the globalization function including a message to be output via a user-interface, the message being in a first language. The method also includes generating function-message data that associates a function identifier of the globalization function with a message identifier of the message. The method also includes generating, automatically, a test case for verifying the globalization function outputs the message via the user-interface in a second language using the function-message data. The method also includes creating and broadcasting a test report to a development team, the test report indicating a result of executing the test case.
