Is it possible to find out if an Android application runs as part of an instrumentation test

Question

Is there a runtime check for an application to find out if it runs as part of an instrumentation test?

Answer 1

This work for me because no actual device is running

public static boolean isUnitTest() {
    return Build.BRAND.startsWith(Build.UNKNOWN) && Build.DEVICE.startsWith(Build.UNKNOWN) && Build.DEVICE.startsWith(Build.UNKNOWN) && Build.PRODUCT.startsWith(Build.UNKNOWN);
}
