This page outlines some of the Marionette methods +that can be useful to you. + +Please note that the best tools for debugging are the `ones that ship with +Gecko`_. This page doesn't describe how to use those with Marionette.

Either because it happens too fast, the window isn't big enough or +you are manipulating a remote server! There are two methods that can help you +out. The first is :func:`~Marionette.screenshot`:: + + marionette.screenshot() # takes screenshot of entire frame + elem = marionette.find_element(By.ID, 'some-div') + marionette.screenshot(elem) # takes a screenshot of only the given element + +Sometimes you just want to see the DOM layout. You can do this with the +:attr:`~Marionette.page_source` property. Note that the page source depends on +the context you are in:: + + print(marionette.page_source) + marionette.set_context('chrome') + print(marionette.page_source) -- cgit v1.2.3
