Question

I have an Android Test Application in which I run several tests.
I use various assert calls such as assertEquals, assertTrue, assertNull and so on. When such an assert fails, I wish to save the stack trace to a file on the device. Does such a thing already exist or do you have any tips on how I could implement it?

Answer 1

You can just catch AssertionError

try {
    assertEquals(true, true);

} catch (AssertionError ex) {
    // code that write exception to file
}

Or more advanced you can use acra and implement your own ReportSender.
