Question

Hii i am new to junit test for android so my question is i have 6 EditText fields and one Button by pressing the Button it will check weather the field length of EditText fields are zero,if they are zero then it will show a Toast and otherwise it will go to another Activity so here is the my code

Button.OnClickListener okListener = new Button.OnClickListener() {
        public void onClick(View arg0) {
            if(text1.getText().toString().length()==0 || text2.getText().toString().length()==0||text3.getText().toString().length()==0||   text4.getText().toString().length()==0||text5.getText().toString().length()==0||    text6.getText().toString().length()==0||txt7.getText().toString().length()==0||txt8.getText().toString().length()==0){
                Toast msg = Toast.makeText(ActivityOne.this,
                        "Field shouldn't left blank", Toast.LENGTH_LONG);
        msg.show();
}

i got to know how to write the Testcases for if statement anybody has idea about how write Testcases for Toast. using Robotium also not a issue.

For example:

// JUnit class
Button.OnClickListener okListener = new Button.OnClickListener() {
            public void onClick(View arg0) {
                assertTrue(text1.getText().toString().isEmpty() || 
                            text2.getText().toString().isEmpty()||
                            text3.getText().toString().isEmpty()||
                            text4.getText().toString().isEmpty()||
                            text5.getText().toString().isEmpty()|| 
                            text6.getText().toString().isEmpty()||
                            txt7.getText().toString().isEmpty()||
                            txt8.getText().toString().isEmpty());
    }

public void testButtons() {
    yourButton.setOnClickListener(okListener);
    okListener.onClick(yourButton);
}

PS1: use String.isEmpty() instead of String.length() == 0.

PS2: I suggest you use an array/List for your EditText instead. Having one field for each is really a bad way of doing it. What happens if you add/remove one EditText? You would need to scan all your code to find that EditText and remove it. Using an array/List you only need to update the array/List.
