Options for Manual Test Case Development &#038; Management

The purpose of developing test cases is to ensure the application functions as expected for the customer. Test cases provide basic application documentation for every function, feature, and integrated connection. Test case development often detects defects in the design or missing requirements early in the development process. Additionally, well-written test cases provide internal documentation for all application processing. Test case development is an important part of determining software quality and keeping defects away from customers.

How Testers Can Remain Valuable in Agile Teams

Traditional software testers must step up if they want to remain relevant in the Agile environment. Agile will most probably continue to be the leading form of the software development process in the coming years.

How to Recognize and Hire Top QA / DevOps Engineers

With the rising demand for new services and technologies in the IT, manufacturing, healthcare, and financial sector, QA/ DevOps engineering has become the most important part of software companies. Below is a list of some characteristics to look for when interviewing a potential candidate.

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.

And the Winner Is: Aggregate Model-based Testing

In my last blog, I investigated both the stateless and the stateful class of model-based testing. Both have some advantages and disadvantages. You can use them for different types of systems, depending on whether a stateful solution is required or a stateless one is enough. However, a better solution is to use an aggregate technique that is appropriate for each system. Currently, the only aggregate solution is action-state testing, introduced in the book Paradigm Shift in Software Testing. This method is implemented in Harmony.
