i have just created login screen project.I wrote the testcase for that.I dont know how to enter the text in textbox in JUnit test case. i just did like this

         public void testlogin() {
    final String n1 = "adithi";
    final String p1 = "adithi";
    String name, pass;
    editUname.clearComposingText();
    editPswd.clearComposingText();
    TouchUtils.tapView(this, editUname);
    sendKeys("adithi");
    TouchUtils.tapView(this, editPswd);
    sendKeys("adithi");

    activity.runOnUiThread(new Runnable() {

          public void run() {


            signinbtn.performClick();
          }
        }); 

        name = editUname.getText().toString();

        pass = editPswd.getText().toString();

    Log.e("name",name); 
    Log.e("Password",pass);
    assertEquals(n1, name);
    assertEquals(p1, pa开发者_开发百科ss);

Its a simple one and I have done a small mistake in giving input to JUnit.we must give as

       sendKeys("A D I T H I");

It works now.

Note. I'm not a Java person but..

Your test is failing because well its failing, your code is not running as you expected.It says expected:<Karthika> but was:<>

So the string from your UI is probably null. You're putting the string Karthika in the UI, then your test expects both strings to be adithi, but it fails saying it was null.

1. Somewhere the text in your UI goes null.
2. I think it should be assertEquals(actualvar, whatyouexpect); like assertEquals(name, n1);
