Each .qml file can consist of one or two stages. The + first stage is when the file is first displayed. The content is + grabbed and matched against 'base' samples defined in the .qml file + itself. The samples contain a pixel position, and RGB value and a + margin of error. The samples are defined in the .qml file so it is + easy to make the connection between colors and positions on the screen. + + If the base stage samples all succeed, the test emits + 'enterFinalStage' on the root item and waits for the .qml file to + update the value of 'finalStageComplete' The test can set this + directly or run an animation and set it later.
