The GuiApp class

Learning Web UI test automation in Arjuna starts with the concept of GuiApp object.

A web application is represented using a GuiApp object. To automate your web application, you create an instance of GuiApp and call its methods or methods of its objects for automation purpose.

Web automation facilities in Arjuna use Selenium WebDriver as the underlying browser automation library.

Launching a Web Application

google = GuiApp()
google.launch(blank_slate=True)
google.go_to_url("https://google.com")
google.quit()

  1. You can create an object of GuiApp. By default, GuiApp uses Arjuna’s reference Configuration. In turn, it uses the corresponding options to launch the underlying automator. You can change this by passing the Configuration object using config argument of the App constructor.

  2. You can launch the GuiApp. Here, we pass blank_slate as True as no base URL is associated as of now with the GuiApp (see next section).

  3. Here the GuiApp uses the reference Configuration of Arjuna where default browser is Chrome. So, Chrome is launched as the browser.

  4. You can use its go_to_url method to go to Google search page.

  5. You can quit the app using quit method of GuiApp.

Associating a App with a Base URL

You can associate the GuiApp with a base URL by providing url arg while creating its object. Now the app knows where to go when it is launched. If this represents your situation (which mostly is the case), then it leads to much simpler code as follows:

google = GuiApp(url="https://google.com")
google.launch()
google.quit()

Setting GuiApp Base URL in Configuration

During initilization, GuiApp automatically looks for the ArjunaOption.APP_URL option in the Configuration object associated with it. It means you can provide this option in any of the following ways:
  • Modify Reference Configuration

    • Add this option in project.yaml file.

    • Provide it as a CLI option.

  • Use ConfigBuilder to update or create a new Configuration. Pass it as argument while instantiating GuiApp, for example:

cb = Arjuna.get_config().builder
cb.option(ArjunaOption.APP_URL, "https://google.com")
config = cb.register()

google = GuiApp(config=config)
google.launch()
google.quit()
