  6. Move the mouse pointer to the right hand side of the flow of events, click on the drop down menu (Menu) and select Main. This drop down menu is for selection of test case. Main is the default one.
    select main
    Now, the flow of events page is divided into three columns - Steps, Procedures and Expected Results. By walking through the steps, the use case is said to be completed. Procedures and expected results are made for testing purposes. Procedures are the steps needed to test a step, while expected results are the outcome expected by performing the testing procedures.

  7. We want to start by writing a valid test case. In step one, we shall test the entering of username by entering peter, assuming that peter is a valid and existing user, and expect to have name peter show on the username field. Enter Fill in peter as username in Procedures cell of step 1. There is no doubt that entering text in a field will have the text appear on the field, so we simply omit expected results here. If you like you can still enter Text "peter" show in username field, but just look a bit cumbersome.
    enter proc step1
  8. For step two Enter password, specify Fill in mypwd as password in Procedures cell. In order to make sure a proper password field is used, we need to specify the expected results by entering Five asterisk (i.e. *) characters are shown in Expected Results cell.
    enter proc step2
  9. For step three, specify Click [Submit] in Procedures cell. Enter Peter's Inbox is shown in expected results.
    enter proc step3
