Pouria Derakhshanfar

Postdoctoral Researcher

Delft University of Technology

My name is Pouria Derakhshanfar. I am a postdoctoral researcher in the Software Engineering Research Group (SERG) of the Delft University of Technology. I am currently involved in an H2020 funded project called DevOps for Complex Cyber-physical Systems (COSMOS). I am also part of the Computational Intelligence for Software Engineering Lab (CISELab). Earlier, I obtained my Ph.D. in Computer Science from the Delft University of Technology, where I defended my dissertation, entitled “Carving Information Sources to Drive Search-Based Crash Reproduction and Test Case Generation”. During my Ph.D., I was involved in another EU H2020 funded project, called Software Testing AMPlification (STAMP), where I developed new search-based approaches for crash replication and test amplification in a DevOps context.

My career goal is to combine human and artificial intelligence to implement tools and techniques to ease software development and testing tasks in industrial software projects.

My Tools

Botsing (2018-current): An open-source search-based crash reproduction framework.
Cling (2019-current): An open-source search-based test generation tool for class integration testing.
ExRunner (2018-current): A bash-based infrastructure for running multiple instances of crash reproduction tools on 200 hard-to-reproduce crashes. ExRunner can be used to perform empirical evaluations of different crash reproduction techniques.
TestKnight (2021-current): A plugin for IntelliJ IDEA that helps developers in writing automatic tests. This plugin allows developers to design test-suites based on structural and side-effect analysis of the code as well as inspect how the test-suite evolves.
SDC-prioratizer (2021-current): A test case prioritization tool for self-driving cars. This tool prioritizes virtual tests for self-driving cars according to static features of the roads used within the driving scenarios.
TestKnight (2022-current): A plugin for IntelliJ IDEA that re-introduces how an automated test generator can be used in the development environment. With this tool, developers can ask TestGenie to generate a test case covering any testing goal (e.g., an uncovered line or branch in the software under test). The test generated by TestGenie will be suggested to developers a couple of minutes after the request. Then, the developer can either use the test as it is or the test can be modified and integrated into the automated testing framework.
