Shift Left Testing

Hey there, fellow software tester! Let’s talk about something that’s been revolutionizing the way we approach testing – left shift testing!

So what is left shift testing, you ask?

Well, it’s a way of bringing testing to the forefront of the software development process, rather than treating it as an afterthought. Instead of waiting until the end of the development cycle to test the software, left shift testing involves testing early and often, starting as soon as possible in the development process.

Why is this so important?

Because it helps catch defects and issues earlier in the process, when they’re easier and cheaper to fix. By incorporating testing into the development process, we can ensure that software is of higher quality and more reliable, which ultimately leads to happier customers.

There are some common mistakes that can be made when implementing left shift testing.

For example, some teams may focus too much on testing the user interface, rather than testing the underlying functionality. Others may skip important testing steps, such as boundary testing or negative testing.

What are some best practices for left shift testing?

One key principle is collaboration – testers should be working closely with developers and other stakeholders throughout the development process. Another important practice is test automation, which can help speed up the testing process and ensure consistent and reliable results.

It’s also important to focus on risk-based testing, where the most critical and high-risk areas of the software are tested first. And don’t forget about exploratory testing, which can help uncover unexpected issues and provide valuable insights into the software.


So there you have it – left shift testing is all about bringing testing to the forefront of the development process, catching issues earlier, and ensuring higher quality software. By avoiding common mistakes and following best practices, we can make left shift testing a valuable and effective part of our software testing toolbox.
