Continuous delivery and continuous deployment offer testers opportunities for growth

Development practices are constantly changing and as testers, we need to embrace change. One of the changes that we can experience is the move from monthly or quarterly releases to continuous delivery or continuous deployment. This move to continuous delivery or deployment offers testers the chance to learn new skills.

What Agile Testing (Actually) Is

So, now that the first installment of this two fold article has been published (hence you might have an idea of what Agile Testing is not in my opinion), I’ve started feeling the pressure to explain what Agile Testing actually means to me.

13 Best Java Testing Frameworks For 2023

The fact is not alien to us anymore that cross browser testing is imperative to enhance your application’s user experience. Enhanced knowledge of popular and highly acclaimed testing frameworks goes a long way in developing a new app. It holds more significance if you are a full-stack developer or expert programmer.

A Step-By-Step Guide To Cypress API Testing

API (Application Programming Interface) is a set of definitions and protocols for building and integrating applications. It’s occasionally referred to as a contract between an information provider and an information user establishing the content required from the consumer and the content needed by the producer.

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.
