SAMINT-MILI 2036 Master’s Thesis 30 credits May 2020 Agile Practices in Commercial SaaS Teams A case study on the adoption of agile practices in non-software teams Bruno Petersen Master’s Programme in Industrial Management and Innovation Masterprogram i industriell ledning och innovation Abstract Agile Practices in Commercial SaaS Teams Bruno Petersen Faculty of Science and Technology Agile software development methods have seen great success in software Visiting address: Ångströmlaboratoriet teams. Research on the topic of adopting agile methods in development teams Lägerhyddsvägen 1 is extensive. In the literature key enabling factors are identified and numerous House 4, Level 0 benefits of agile ways of working are named. Less attention has been payed to Postal address: the non-software functions in software development organizations, though. Box 536 Moreover, little is known about how well the enabling factors and benefits for 751 21 Uppsala software teams translate to other teams in the organization. The goal of this Telephone: study is to evaluate what benefits agile methods provide to non-software teams, +46 (0)18 – 471 30 03 whether the enabling factors are similar and what the challenges and drawbacks Telefax: for adopting agile methods in commercial teams are. Using the case of the +46 (0)18 – 471 30 00 Swedish Software-as -a-Service company Funnel, which introduced agile Web page: practices into their commercial teams, these questions are tackled. The study http://www.teknik.uu.se/student-en/ finds that knowledge transfer and governance are core areas that need to be engaged in during the adoption process. With decisions being made more autonomously ensuring the exchange of relevant information is crucial. -

Model-Based Fuzzing Using Symbolic Transition Systems
Model-Based Fuzzing Using Symbolic Transition Systems Wouter Bohlken [email protected] January 31, 2021, 48 pages Academic supervisor: Dr. Ana-Maria Oprescu, [email protected] Daily supervisor: Dr. Machiel van der Bijl, [email protected] Host organisation: Axini, https://www.axini.com Universiteit van Amsterdam Faculteit der Natuurwetenschappen, Wiskunde en Informatica Master Software Engineering http://www.software-engineering-amsterdam.nl Abstract As software is getting more complex, the need for thorough testing increases at the same rate. Model- Based Testing (MBT) is a technique for thorough functional testing. Model-Based Testing uses a formal definition of a program and automatically extracts test cases. While MBT is useful for functional testing, non-functional security testing is not covered in this approach. Software vulnerabilities, when exploited, can lead to serious damage in industry. Finding flaws in software is a complicated, laborious, and ex- pensive task, therefore, automated security testing is of high relevance. Fuzzing is one of the most popular and effective techniques for automatically detecting vulnerabilities in software. Many differ- ent fuzzing approaches have been developed in recent years. Research has shown that there is no single fuzzer that works best on all types of software, and different fuzzers should be used for different purposes. In this research, we conducted a systematic review of state-of-the-art fuzzers and composed a list of candidate fuzzers that can be combined with MBT. We present two approaches on how to combine these two techniques: offline and online. An offline approach fully utilizes an existing fuzzer and automatically extracts relevant information from a model, which is then used for fuzzing. -

These bottlenecks include finding and setting up test environments, test configurations, and test results implementation. These issues are not industry specific. They can be experienced in manufacturing, service businesses, and governments alike. They can be reduced by having a thorough understanding and a disciplined, mature implementation of Continuous Testing and related recommended engineering practices. The best place to start addressing these challenges is having a good understanding of what Continuous Testing is. Marc Hornbeek, the author of Engineering DevOps, describes it as: “A quality assessment strategy in which most tests are automated and integrated as a core and essential part of DevOps. Continuous Testing is much more than simply ‘automating tests.’” In this whitepaper, we’ll address the best practices you can adopt for implementing Continuous Quality and Testing on the AWS Cloud environment in the context of the DevOps model. -
