Developers and Bugs – why are they happening again and again?

Entering the world of testers, one question started to formulate in my mind: “what is the reason that bugs happen?”.

Best 13 Tools To Test JavaScript Code

Unit and functional testing are the prime ways of verifying the JavaScript code quality. However, a host of tools are available that can also check code before or during its execution in order to test its quality and adherence to coding standards. With each tool having its unique features and advantages contributing to its testing capabilities, you can use the tool that best suits your need for performing JavaScript testing.

How To Automate Toggle Buttons In Selenium Java

If you pay close attention, you’ll notice that toggle switches are all around us because lots of things have two simple states: either ON or OFF (in binary 1 or 0).

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.

Pair testing strategy in an Agile environment

Pair testing can help you complete your testing tasks faster and with higher quality. But who can do pair testing, and when should it be done? And what form of pair testing is best for your circumstance? Check out this blog for more information on how to conduct pair testing to optimize its benefits.
