Application Testing
You have now completed the development stages of a small, but workable
application. The next step is to test it.
As a developer, you can test your application without leaving the
developer application. The Test option on the developer main menu runs
your application as it appears to the end user. When you test an
application using the application testing option, you have access to some
facilities that are not available to end users. These facilities can
help you identify problems.
Any Problems?
Sometimes, things can go wrong when you test your application. The
application may not behave as expected or it may even abort and return
you to the developer main menu.
The remainder of this lesson assumes that nothing does go wrong. If
things don't work as you expected, refer to "Handling Problems". It
covers the most common problems that may occur.
If any problems you encounter are not explicitly described, refer to the
HP ALLBASE/4GL Developer Reference Manual for further information.
To test your application:
1. Return to the developer main menu and select the Test option.
This loads a new HP ALLBASE/4GL environment and executes the
initial action for the application. The initial action is either
a menu or process. This is defined in the administrator
definition for the application. The main menu for the application
should appear.
2. Activate Product Details
This executes the product_proc process. This process in turn
displays the product_scrn screen.
3. Enter data into the screen as follows:
Action Explanation
------------------------------------------------------------------------------
Enter abc HP ALLBASE/4GL alters the characters to upper-case.
It also responds with a message to tell you that
the data is less than the required minimum length.
(Remember that you specified that this field must
be six characters long.) This is a standard HP
ALLBASE/4GL field validation.
Enter 123456 Before moving the cursor to the next field HP
ALLBASE/4GL executes the product_key_read function
associated with this field. This function is an
after function because it is executed after the
field is committed. The function reads the product
file and searches for a record with a primary key
that matches the product number just entered. This
record does not exist, so HP ALLBASE/4GL displays a
warning message. For the HP TurboIMAGE/XL based
application, an HP TurboIMAGE/XL warning message is
also displayed.

the process driving the screen. The process writes
the new record to the file and then returns to the
start, displaying the screen again.
