What is the role of test automation in agile and DevOps? DevOps is critical in the enterprise. And to be successful, you’ll need to have a good strategy for testing.
A DevOps testing strategy must be focused on continuous testing. Testing cannot be DevOps or Agile unless it’s continuous.
An important part of DevOps is continuous integration/continuous delivery (CI/CD). And between CI and CD, there should be continuous testing.
Without continuous testing, there will be:

Here are some benefits you can expect from a strong strategy.
Deliver faster feedback. You don’t want your developers to have to go back to code they worked on 1–2 weeks ago to fix a bug. You want them to get faster feedback, so they can fix issues right away. And you can release faster.
Cover more platforms by implementing a strategy that scales test automation. This can be challenging, as mobile and web platforms are fragmented. But, when you utilize the right test automation tools, you can ensure coverage across more platforms in faster time.
Finally, reduce time constraints on test executions. Execution time needs to be shorter. When you run at scale, in parallel, and with the right tools, you can accelerate the time to market.
How do you ensure a solid strategy so you can experience the benefits? To do that, you need to follow these testing in DevOps best practices.
The ideal state for most organizations is continuous testing. But organizations are struggling to find a solid foundation for test automation. Here are our best practices for developing a testing strategy.
To build a successful strategy for DevOps testing, you’ll need to scale test automation — on web and mobile.
There are 3 ways organizations are scaling web testing today:
There are also 3 ways organizations are scaling mobile testing today:
There are two major solutions for scaling test automation for web and mobile (and across browsers). One option is to use open source frameworks (e.g., Cucumber). The other option is to do codeless (e.g., Selenium).
To have a successful strategy, you’ll need automation across all of your testing types. This includes functional tests as well as nonfunctional tests, including performance, accessibility, and unit code coverage.
Automation within CI and outside CI is at the core of Agile and DevOps. Ensuring that automation continuously adds value — and meets the goals above — requires a stable test automation suite.
Your test automation suite must be continuously reviewed, audited, maintained, and refactored when needed.
As product code changes, so do testing. Make sure your teams are looking into the test scenarios and updating them whenever it’s required.
Another important step for your strategy is to use supporting frameworks.
Here are some examples of where to use supporting frameworks:
To release high quality fast, teams should rely on a robust lab:
In addition, such lab should be able to support all of the advanced automation capabilities. This includes audio, location, image, and other digital related capabilities that teams need to automate.
At the heart of each testing activity there’s a test report. The more detailed and actionable the report is, the faster developers can figure out the root cause of failures and move forward.
Ensure that you’re using a robust reporting platform as part of your entire testing activities.
Headless browsers play a role in your testing strategy for web apps. These are developer-friendly tools. Using headless browsers helps developers deliver a more stable build to test engineers. Plus, headless browsers — like Google Puppeteer — are free.
This plays a role in scaling test automation, so you can succeed with your DevOps test strategy.
Your strategy for DevOps testing won’t succeed unless the full team is involved.
To do test automation at scale for each pull request and code change, you need everyone:
What sets leading companies apart in the world of test automation? In this session, Johnny Lam, Solutions Engineer, draws on his experience working shoulder to shoulder with trailblazing global companies — from Fortune 500 to startups — to strategize, implement, and execute their test automation initiatives. What have they done to speed up and scale their testing cost-effectively? Get the answers in this session.
To succeed in your strategy for DevOps testing, you’ll need more than the best practices. You’ll need the right tools.
