Abstract [en]

Automated tests have become the most sought after method of testing

in today’s market. Automating systems is generally found to be

cheaper, faster and more reliable than manually operating them. For

this reason many companies decide to make the switch over to this inexpensive

yet efficient way of testing, only to realize that their costs

have in fact gone up. The reasons for this could be poor planning, automating

too much too soon or even automating unnecessary parts of

the system. This study takes a closer look at the effects of automating

tests used on interlocking systems. A tool has been developed as a part

of the automated tests at Bombardier. The main function of the tool is

to speed up the testing process by automatically generating test cases

rather than having a worker write them down. The aim of this paper is

to present this recently developed tool and show how its use significantly

reduces testing time, costs and workload compared to the manual tests

used today.
