Shift-Left Testing in the Enterprise and the Case for Open Source

Why continuous testing and open source are a perfect match

I recently visited the offices of CA Technologies (one of Abstracta’s partners) in Santa Clara, where I had the chance to discuss shift-left testing, continuous testing, and why and how to turn to open source solutions to accomplish them.

Check out the (then) live broadcast of our chat with CA Technologies’ Eric Odell, Director of Continuous Testing Solutions Marketing, and Refael Botbol, Performance Testing Domain Expert.

Main Takeaways

Shift-Left Testing vs. Continuous Testing

First off, if you are not clear about shift-left testing or continuous testing, continuous testing is the notion of testing throughout the development cycle, as opposed to only at the end, which is typical within waterfall environments. “Shift-left” testing is how this is accomplished, as it shifts the beginnings of testing to earlier stages, allowing developers to integrate testing into their daily activities and take more ownership of building quality code.

The #1 Hurdle of Shift-Left Testing

For shift-left testing to take off in an organization, a great change in culture must occur first. Teams are usually set in their traditional ways of working, and when they consider shifting, they must consider how the methods, processes, skills, tooling, etc. will need to change. Even more important, what will need to happen to get all the roles within the organization to align properly?

The Response to Shifting Left

The TCOE (Testing Center of Excellence) will find itself delegating some of its work to the developers, assigning them more testing activities. In the teams who do this best, the testers become “coaches”, training developers on how to write better code, avoid bugs, and own unit testing. The advantage of this is that the tester who used to be busy, frantically writing all of the test cases, now has time to delve deeper into the product, working on business cases, penetration testing, performance testing, and so on. This sharing of the responsibility for QA leads to a higher level of achieved quality, as more of the bases get covered.

Why Are Enterprises Shifting to Open Source?

Open source tools offer a high level of flexibility and have reached a maturity where you can see much more confidence in them today in the tech community. With the significant expansion of the open source community, seemingly endless contributors share their add-ons and solutions with the world, making everyone’s lives that much easier. Today there are also several companies who make solutions for enterprise to use on top of open source, such as BlazeMeter. Thus, it’s no surprise, as Eric Odell mentions, that

How to Convert Legacy Testing Scripts to Open Source

So, how do you actually make the jump? Undoubtedly, like all things worthwhile, it will require some effort up-front. Luckily, BlazeMeter has released an incredible, free tool that converts legacy scripts (LoadRunner HTTP to JMeter and LoadRunner TruClient to Selenium) to open source in a matter of minutes. The scripts may need some minor tweaking and perfecting afterward, but it will save the team a tremendous amount of man hours.
