Servoy has built-in support for Unit Testing. The integration adds the following to the Servoy environment:
Creating testcases is as straightforward as creating a function with a name that is prefixed by 'test_':
The JSUnit node in the Solution Explorer provides easy access to the different supported assert functions
Testcases can be added on application level in the global scope of on form level in the form scope.
Each scope can contain a setUp and/or tearDown function. The setUp function is called BEFORE running each testcase in the scope and the tearDown function is called AFTER running each test in the scope. The setUp and tearDown function allow the developer to create the right circumstances for testcases to run and cleanup afterwards. Note that the setUp() and tearDown() methods are called before and after EACH test methods, as each single test is supposed to be independant.
When testing asynchronous code, for example a queued method using the queueMethod method of the Headless Client plugin with a notifyCallback method or a executeAsyncRequest on the HTTP plugin with a success/errorCallback and the UnitTest needs to test the result of the callback method, application.updateUI(Number:milliseconds) can be used inside a loop to wait for the callback to be invoked and test it's result.
The difference between these two operators is that the equal operator does type conversion if the objects on both sides of the operator are of different types, while the strict equal operator does not.
