A Reconsideration of Software Testing Metrics

There is just one area where each member of the software testing community has a distinct point of view! Metrics! This contentious issue sparks intense disputes, and most conversations finish with no definitive conclusion. It covers a wide range of topics: How can testing efforts be measured? What is the most effective technique to assess effectiveness? Which of the many components should be quantified? How can we measure the quality of our testing performance, among other things?

QA Innovation – Using the senseshaping concept to discover customer needs

QA Innovation - Using the senseshaping concept to discover customer needs QA 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.

The Art of Testing the Untestable

It’s strange to hear someone declare, “This can’t be tested.” In reply, I contend that everything can be tested. However, one must be pleased with the outcome of testing, which might include failure, financial loss, or personal injury. Could anything be tested when a claim is made with this understanding?

Webinar: Building Selenium Automation Framework [Voices of Community]

Even though several frameworks are available in the market for automation testing, Selenium is one of the most renowned open-source frameworks used by experts due to its numerous features and benefits.

Stop Losing Money. Invest in Software Testing

I was once asked at a testing summit, “How do you manage a QA team using scrum?” After some consideration, I realized it would make a good article, so here I am. Understand that the idea behind developing software in a scrum environment is for development teams to self-organize.
