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.

Putting Together a Testing Team

As part of one of my consulting efforts, I worked with a mid-sized company that was looking to move toward a more agile manner of developing software. As with any shift in work style, there is some bewilderment and, for some, considerable anxiety. People are being challenged to leave their comfort zones and embrace a continuously changing, dynamic working environment. And, dare I say it, testing may be the most ‘disturbed’ of the software roles in agile development.

7 Skills of a Top Automation Tester in 2021

With new-age project development methodologies like Agile and DevOps slowly replacing the old-age waterfall model, the demand for testing is increasing in the industry. Testers are now working together with the developers and automation testing is vastly replacing manual testing in many ways. If you are new to the domain of automation testing, the organization that just hired you, will expect you to be fast, think out of the box, and able to detect bugs or deliver solutions which no one thought of. But with just basic knowledge of testing, how can you be that successful test automation engineer who is different from their predecessors? What are the skills to become a successful automation tester in 2019? Let’s find out.
