I have a rather simple QGIS standalone Python app (2.8.2, Windows 7/64), with some published methods to create different types of geometric primitives (rectangles, circles).

class MyApp(QMainWindow, UI_MyApp)
    def __init__(self, ...)
    def circle(self, x, y, radius)

def run_tests()

def main()
    app = QApplication(sys.argv)
    map = MyApp()

Now I want to run some automated tests against these methods, in this example circle().

It doesn't matter if I include the test calls inside the class itself (as shown above, e.g. connected with a button in the UI) or kept in a separate module: in both cases all graphics are not drawn until run_tests() finished.

How can I implement a (separate) test module which can call methods of MyApp() application with immediate response after each call and thus acting like an API?


Have a look at the unittest documentation, it provides great examples for coding your functions so that they are easily testable.

You can then have a look at how to set up your project folder.

And then finally have a look at Best practices in writing automated tests for QGIS plugins
