Currently, it doesn't detect when the apk file cannot be installed, so it proceeds to run the tests and reports back 0 tests. Need to throw an explicit exception.
Reopened, as although it throws an exception when the file does not exist, it doesn't throw if adb reports that there is a problem with the apk file - for example a certificate mismatch.
