Unlocking the Secrets of Property-Based Testing

"So the fundamental proposition of property based testing is when the system gets too complicated, it is not possible for humans to write every test cases. So rather we want these test cases to be generated automatically." - Nikhil Barthwal

In this episode, I chat with Nikhil Barthwal about property-based testing. We go into how property-based testing can uncover the hidden bugs that often slip past human testers. With its capacity to automatically generate a multitude of test cases, this method helps us see beyond typical limitations. Nikhil also shares when property-based testing may not be ideal, like when it incurs high resource costs. He emphasizes that this approach serves as an assistant to testers rather than a replacement, enhancing productivity and reliability.

Nikhil Barthwal is passionate about developing decentralized systems. He has several years of professional experience in large corporations as well as in smaller start-ups and acts as a mentor for various start-ups. He is also a guest speaker at various international conferences and gives talks on topics related to decentralized systems and software quality.

Highlights:

• Property-based testing finds hidden bugs that humans miss.
• It generates many test cases automatically.
• Not ideal when it incurs high resource costs.
• It complements testers, not replacing them.
• Enhances productivity and reliability in testing.
