SIMON is an automated testing application developed by WM-Data Consulting in Växjö, Sweden. Previously the test cases, called BIFs, run by SIMON to test the applications under test has been written manually in a very time consuming manner offering no protection against errors in the structure or misspellings. This thesis investigates a replacement to the manual method when creating the BIFs; my own developed application called the BIF-Editor. The usage of the BIF-Editor guaranteed correct syntax and structure and made the creation of the BIFs faster, but did it increase the quality of the BIFs? So to evaluate the BIF-Editor, the quality regarding path coverage of BIFs manually created was compared with BIFs created during the same elapsed time using the BIF-Editor. This evaluation showed that the usage of the BIF-Editor increased the quality of the BIFs by making the creation safer, but primarily faster which enabled the user to produce more BIFs than previously possible resulting in a raised path cover.
