Agile in Distributed Development – A Formula for Success

Agile has unquestionable benefits. The mainstream method has assisted numerous businesses in increasing organizational flexibility as a result, developing better, more intuitive software. Distributed development is also an important strategy for software companies. It gives access to global talent, the use of offshore outsourcing to reduce operating costs, and round-the-clock development.

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.

20 Best VS Code Extensions For 2023
