How Testers Can Remain Valuable in Agile Teams

Traditional software testers must step up if they want to remain relevant in the Agile environment. Agile will most probably continue to be the leading form of the software development process in the coming years.

Assessing Risks in the Scrum Framework

Software Risk Management (SRM) combines a set of tools, processes, and methods for managing risks in the software development lifecycle. In SRM, we want to make informed decisions about what can go wrong at various levels within a company (e.g., business, project, and software related).

Options for Manual Test Case Development & Management

The purpose of developing test cases is to ensure the application functions as expected for the customer. Test cases provide basic application documentation for every function, feature, and integrated connection. Test case development often detects defects in the design or missing requirements early in the development process. Additionally, well-written test cases provide internal documentation for all application processing. Test case development is an important part of determining software quality and keeping defects away from customers.

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.
