Fault-Based Testing and the Pesticide Paradox

In some sense, testing can be more difficult than coding, as validating the efficiency of the test cases (i.e., the ‘goodness’ of your tests) can be much harder than validating code correctness. In practice, the tests are just executed without any validation beyond the pass/fail verdict. On the contrary, the code is (hopefully) always validated by testing. By designing and executing the test cases the result is that some tests have passed, and some others have failed. Testers do not know much about how many bugs remain in the code, nor about their bug-revealing efficiency.

Why does DevOps recommend shift-left testing principles?

Companies are using DevOps to quickly respond to changing market dynamics and customer requirements.

20 Best VS Code Extensions For 2023

With the change in technology trends, there has been a drastic change in the way we build and develop applications. It is essential to simplify your programming requirements to achieve the desired outcomes in the long run. Visual Studio Code is regarded as one of the best IDEs for web development used by developers.

QA Innovation – Using the senseshaping concept to discover customer needs

QA Innovation - Using the senseshaping concept to discover customer needsQA testers have a unique role and responsibility to serve the customer. Serving the customer in software testing means protecting customers from application defects, failures, and perceived failures from missing or misunderstood requirements. Testing for known requirements based on documentation or discussion is the core of the testing profession. One unique way QA testers can both differentiate themselves and be innovative occurs when senseshaping is used to improve the application user experience.
