RESTest: automated black-box testing of RESTful web APIs

Testing RESTful APIs thoroughly is critical due to their key role in integration. Existing tools for the automated generation test cases in this domain have shown great promise, but their is limited as they mostly rely on random inputs, i.e., . In this paper, we present RESTest, an open source black box testing framework for RESTful web APIs. Based on the API , RESTest supports the generation of test cases using testing techniques such as fuzzing and constraint-based , among others. RESTest is developed as a framework and can easily extended with new test case generators and test writers different programming languages. We evaluate the tool in two : offline and online testing. In the former, we show how can efficiently generate realistic test cases (test inputs and oracles) that uncover bugs in real-world APIs. In the latter, we RESTest’s capabilities as a continuous testing and monitoring . Demo video: https://youtu.be/1f_tjdkaCKo.
