Starting &#038; growing a QA Testing career

The QA testing career includes following an often long, winding road filled with fun, chaos, challenges, and complexity. Financially, the spectrum is broad and influenced by location, company type, company size, and the QA tester’s experience level. QA testing is a profitable, enjoyable, and thriving career choice.

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.

Keeping Quality Transparency Throughout the organization

In general, software testers have a challenging job. Software testing is frequently the final significant activity undertaken prior to actually delivering a product. Since the terms “software” and “late” are nearly synonymous, it is the testers that frequently catch the ire of the whole business as they try to test the software at the end. It is the testers who are under pressure to finish faster and deem the product “release candidate” before they have had enough opportunity to be comfortable. To make matters worse, if bugs are discovered in the product after it has been released, everyone looks to the testers and says, “Why didn’t you spot those bugs?” The testers did not cause the bugs, but they must bear some of the guilt for the bugs that were disclosed.

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.
