get_data() uses oeqa test method name and an optional key to get data from image specific "testimage_data.json" file located in image deploy directory. Image recipes can provide custom versions of this file which configures generic tests for a specific image when testing with testimage.bbclass
For example, the parselogs.py runtime test needs image specific configuration when the image has new errors from the kernel which acceptable and can be ignored. Same machine can be used to generate multiple images with different runtime behavior so using image as the key and not machine.
