Hello,
I am trying to integrate Junit to my application for unit testing. I
know I am missing something. Below is the code, please help me
identify the root cause.
I am able to send keys to the default focused edittext, but am unable
to press a button on the same screen. I have printed the id of the
button and it corresponds correctly to the hex id on R on my project.
And am unable to send a button click to that button. I know I am
missing something real obvious to some. I guess I should pick up the
reference of the button from the activity itself, but for that i need
to make the button public. That beats the purpose of using junit
right, I mean I need to have debug code in my production ready
application :).
Also if I replace the runOnUiThread (runnable code) with a
@UiThreadTest, I get a Runtime exception (the android doc seems to
suggest that I should have one of them to avoid having this exception,
but the doc seems outdated and wrong).
Please help. ;-) this time I will wait for responses and wont fix it
myself.
package com.my.android.test;
