A few weeks ago, I landed a new capability to the testing framework to make it easier to write tests where you need chrome Javascript to cause changes in the Native UI. For instance, my initial goal was to use this to test the nsIPromptService. margaret has also used it to test the new Home banner API. Its in some ways a much less polished version of the JavscriptTest framework nalexander wrote. Nick's stuff is great if you're just testing some JS. This is helpful if you've got chrome JS that will trigger/interact with Java UI.
Usage is pretty simple, just put a file in mobile/android/base/tests/roboextender and it will be installed as an addon in the test framework's profile. To load the file just load a chrome url "chrome://roboextender/content/myTestPage.html". That page loads with full chrome privileges, and can load JSM's or access XPCOM components, making it simple to send messages from the page back to java (where you can assert). It also runs locally on the device, which is nice if you're having difficulties connecting to the js-http server on your local computer. Sending messages to the page SHOULD be possible with some reflection, but is left as an exercise to the reader :) Margaret's home banner test is a pretty concise example: http://mxr.mozilla.org/mozilla-central/source/mobile/android/base/tests/testHomeBanner.java http://mxr.mozilla.org/mozilla-central/source/mobile/android/base/tests/roboextender/robocop_home_banner.html?force=1 testHomeBanner.java in this case loads the chrome://roboextender/content/robocop_home_banner.html#test url. Note the hash there tells the chrome to run a particular function. You don't really need to do that if you're only running one function in this test, but its a nifty way to put multiple different tests in one html file (just load the page with a different hash). The test page can then send data back to the java ui, so Java should register for the events it expects: // robocop_home_banner.html Services.androidBridge.handleGeckoMessage(JSON.stringify({type: "TestHomeBanner:MessageShown"})); // testHomeBanner.java eventExpecter = mActions.expectGeckoEvent("TestHomeBanner:MessageShown"); // do something (load the page?) eventExpecter.blockForEvent(); you can also send data back with the event by using: String data = eventExpecter.blockForEventDataWithTimeout(MAX_WAIT_MS); and then assert based on the message contents. Happy testing! Wes _______________________________________________ mobile-firefox-dev mailing list [email protected] https://mail.mozilla.org/listinfo/mobile-firefox-dev
