Abstract [en]

The goal of this thesis project is to improve industrial system testing efficiency. The thesis is mainly focused on the field of telecommunication. Testing is one of the most important steps before selling a product to customers and testing is also an important component of after sale maintenance. The work load for testers can be decreased and more projects could be carried out in parallel, if the testing efficiency can be improved.

The thesis project is carried out within the Ericsson Product Development Unit (PDU) Packet Core System Test section. The goal is to improve the system testing efficiency of the Evolved Packet Gateway, as system testing has gradually become one of the bottle necks for the whole product release. Ericsson wants to accelerate its pace in releasing new products to the market and releasing new software to their customers. An initial investigation was made to get a clear view about how the complete system testing procedure is currently carried out and then, an analysis was made based on this information. Ideas were collected for a proposed new implementation and finally a prototype for the most useful ideas was developed and evaluated to show how the system testing efficiency can be improved.

Finally, these ideas were proved to be valuable for Ericsson PDU Packet Core System Test section and two of them have been adopted and are already under developing.

Abstract [sv]

Målet med detta examensarbete är att förbättra effektiviteten inom industriell systemtestning.  Avhandlingen är främst inriktad på området för telekommunikation. Testning är ett av de viktigaste stegen innan försäljning av en produkt till kunder och testning är också en viktig komponent under underhållsfasen. Genom att förbättra effektiviteten i testerna kan arbetsbelastningen för testare minskas och flera projekt genomföras parallellt.

Examensarbetet har utförts inom Ericssons produktutvecklingsenhet (PDU) Packet Core, avdelning System Test. Avhandlingens mål är att effektivisera systemtestning av Evolved Packet Gateway (EPG), eftersom systemtest gradvis blivit flaskhalsen för hela produktens release. Ericsson vill påskynda takten som de släpper nya produkter på marknaden och ny mjukvara till sina kunder. En första undersökning gjordes för att få en tydlig bild av hur systemtest utförs för närvarande och därefter, gjordes en analys baserat på denna information.  Idéer samlades in för att föreslå en ny implementering och slutligen utvecklades en prototyp av en specifik idé och den harutvärderats för att visa hur effektiviteten hos systemtest kan förbättras.

Slutligen, var dessa idéer visade sig vara värdefullt för Ericsson PDU Packet Core System Test avsnitt och två av dem har antagits och håller redan på att utveckla.
