Introduction. Third-party scripts can cause negative load-time effects. Why is this an issue? Well, in Google’s view, a poorly-optimized page should not rank highly. Instead, search results should favor pages with fundamental design strengths—including JavaScript minification, rapid execution time, and render-friendly scripting. In reflection of this belief, Google has planned the gradual release of a major update to its search algorithm that is scheduled for June through August of 2021.

Dynatrace news. AWS Lambda is the fastest growing technology for serverless workloads and helps developers innovate faster. It removes the burden of managing underlying infrastructure and is broadly adopted for cloud-native application environments. But serverless functions don’t exist in a vacuum. It’s critical that you understand how they impact your customer-facing web applications, mobile apps, or APIs and how they interact with other functions, services, and classic technology stacks.

Projects these days are becoming increasingly complex and any potential risk of failure needs to be managed using available resources that won’t compromise the product’s quality.

In today’s world where ‘data is the new oil’ ( as said by Clive Humby), not giving proper attention to data-driven testing is not justified. If you have an application that needs data input in some form then it will require data-driven testing. Additionally, when during testing your application – there are testing scenarios that require multiple permutations/combinations of input data in your application, then you might have to think of using a test automation tool for automating them.
