Property-based testing: finding bugs that example-based tests miss
📰 Dev.to AI
Learn property-based testing to find bugs that example-based tests miss, ensuring your code's logic holds true at the edges
Action Steps
- Define a property for your function that should always hold true
- Use a property-based testing library to generate random inputs
- Write test cases that check the property for different input scenarios
- Run the tests to identify bugs at the edges of your logic
- Refine your function to ensure the property holds true for all inputs
Who Needs to Know This
Software engineers and developers can benefit from property-based testing to improve code reliability and robustness, while QA engineers can use it to identify edge cases
Key Insight

Property-based testing: finding bugs that example-based tests miss Example-based tests check specific inputs and expected outputs. They're the standard approach, but they only test what you think to test. Property-based testing generates random inputs and checks that certain properties always hold true. It finds bugs at the edges of your logic. A property is a statement that should always be true for your function. For a sort function, the property is that the output is sort
