Why Agile Is Great for Your Business

Agile project management is a great alternative to traditional methods, to address the customer’s needs and the delivery of business value from the beginning of the project. This blog describes the main benefits of Agile for both the customer and the business.

[LambdaTest Spartans Panel Discussion]: What Changed For Testing &#038; QA Community And What Lies Ahead

The rapid shift in the use of technology has impacted testing and quality assurance significantly, especially around the cloud adoption of agile development methodologies. With this, the increasing importance of quality and automation testing has risen enough to deliver quality work.

QA&#8217;s and Unit Testing &#8211; Can QA Create Effective Unit Tests

Unit testing is typically software testing within the developer domain. As the QA role expands in DevOps, QAOps, DesignOps, or within an Agile team, QA testers often find themselves creating unit tests. QA testers may create unit tests within the code using a specified unit testing tool, or independently using a variety of methods.

QA Innovation &#8211; Using the senseshaping concept to discover customer needs

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

Test strategy and how to communicate it

I routinely come across test strategy documents when working with customers. They are lengthy—100 pages or more—and packed with monotonous text that is routinely reused from one project to another. Yawn once more— the test halt and resume circumstances, the defect management procedure, entrance and exit criteria, unnecessary generic risks, and in fact, one often-used model replicates the requirements of textbook testing, from stress to systems integration.
