How To Write End-To-End Tests Using Cypress App Actions

When I started writing tests with Cypress, I was always going to use the user interface to interact and change the application’s state when running tests.

Rebuild Confidence in Your Test Automation

These days, development teams depend heavily on feedback from automated tests to evaluate the quality of the system they are working on.

Keeping Quality Transparency Throughout the organization

In general, software testers have a challenging job. Software testing is frequently the final significant activity undertaken prior to actually delivering a product. Since the terms “software” and “late” are nearly synonymous, it is the testers that frequently catch the ire of the whole business as they try to test the software at the end. It is the testers who are under pressure to finish faster and deem the product “release candidate” before they have had enough opportunity to be comfortable. To make matters worse, if bugs are discovered in the product after it has been released, everyone looks to the testers and says, “Why didn’t you spot those bugs?” The testers did not cause the bugs, but they must bear some of the guilt for the bugs that were disclosed.

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.

LIVE With Automation Testing For OTT Streaming Devices ????

People love to watch, read and interact with quality content — especially video content. Whether it is sports, news, TV shows, or videos captured on smartphones, people crave digital content. The emergence of OTT platforms has already shaped the way people consume content. Viewers can now enjoy their favorite shows whenever they want rather than at pre-set times. Thus, the OTT platform’s concept of viewing anything, anytime, anywhere has hit the right chord.
