Test automation: Flexible way

F-Secure is a global leader in providing security as a service through ISP's and mobile operators [1]. The company first used Agile more than 5 years ago and is still in the transition and building the true Agile culture. Test automation (TA) is one of Agile practices that the company has been focusing on and improving lately [2]. This paper describes how TA has been implemented in the company, benefits and drawbacks of different approaches, and key learnings. Our findings may be of interest and help for other Agile teams using or building a automation test system.
