How To Create Custom Menus with CSS Select

When it comes to UI components, there are two versatile methods that we can use to build it for your website: either we can use prebuilt components from a well-known library or framework, or we can develop our UI components from scratch.

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.

Migrating Test Automation Suite To Cypress 10

There are times when developers get stuck with a problem that has to do with version changes. Trying to run the code or test without upgrading the package can result in unexpected errors.

QA Management &#8211; Tips for leading Global teams

The events over the past few years have allowed the world to break the barriers of traditional ways of working. This has led to the emergence of a huge adoption of remote working and companies diversifying their workforce to a global reach. Even prior to this many organizations had already had operations and teams geographically dispersed.

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.
