Description:

When evolving software we may introduce new corner cases that can pass unnoticed through the test cases in our automated test suite. Since developers rely on other's test suites when changing their code, the more developers work on a module, the more likely it is they slip a bug trough the test suite; that's something we though we had to live with. However, property based testing is emerging as a new hope, our last experiences say that it helps to create test suites more robust to software evolution without forcing us to write tons of "just-in-case test cases."
