I use Robotium as the library for Junit test for my Android application. I wrote some tests which works well. But when I try to write a test for native ActionBar's Up/Home button click, it failed.
My test code is very simple:
Solo solo = new Solo(getInstrumentation(), getActivity());
...
solo.clickOnActionBarHomeButton(); // I expected it will click the Up/Home button of ActionBar
I expected the above code will click the Up/Home button of native ActionBar, but it is failed, nothing was happening on action bar. Why??
P.S. I am using an Android 4.2.1 device.
