the class TestUtils method screenshotTest.

 * The screenshot test takes a screenshot of the screen and compares it to

 * If this is the first time the test is run then the screenshot is taken
 * and saved under the given name in the devices storage. The test passes
 * for this case but a warning is printed to the console. The name will have
 * .png appended to it so it will be identified.<br>
 * This test will only work on devices that support the ImageIO API with PNG
 * file format.
 *
 * @param screenshotName the name to use for the storage, must be unique!
 * @return true if the screenshots are identical or no prior screenshot exists
 * or if the test can't be run on this device. False if a screenshot exists and
 * it isn't 100% identical.
