24 Testing Scenarios you should not automate with Selenium

While there is a huge demand and need to run Selenium Test Automation, the experts always suggest not to automate every possible test. Exhaustive Testing is not possible, and Automating everything is not sustainable.

Project Goal Prioritization in Context of Your Organization’s Strategic Objectives

One of the most important skills for leaders to have is the ability to prioritize. To understand how we can organize all of the tasks that must be completed in order to complete a project, we must first understand the business we are in, particularly the project goals. There might be several project drivers that stimulate project execution and motivate a company to allocate the appropriate funding.

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.
