I'm trying to do instrumentation testing of an activity that uses fragments.
I'm trying to test the onSaveInstanceState by doing this:
/*************/
runTestOnUiThread(new Runnable() {
@Override
public void run() {
instrumentation.callActivityOnSaveInstanceState(activity,
outState);
}
});
instrumentation.waitForIdleSync();
assertEquals(MainActivity.MY_TITLES,
outState.getInt(MainActivity.SELECTED_TAB));
Log.d(TAG, "so far, so good...");
/*************/
That works fine, but that's the end of my test.
The test runner shows this:
---
Running tests
Test running started
Test failed to run to completion. Reason: 'Instrumentation run failed
due to 'java.lang.IllegalStateException''. Check device logcat for
details
Test running failed: Instrumentation run failed due to
'java.lang.IllegalStateException'
---
Looking in logcat, I see this:
---
02-19 08:25:58.840:

far, so good...

The thing that has me perplexed here is that IllegalStateException -
the code it ultimately points back to in the stack trace is in the
onPause() of my activity. I'm trying to commit a fragment transaction
and in the application it works fine - it just fails in my test.
I suspect I'm doing something out of order, but googled all morning
and can't find anything that seems to point me in the right direction.
Any hints?
