Best Practices For a DevOps Testing Strategy
DevOps is critical in the enterprise. And to be successful, you’ll need to have a good strategy for testing.
What Is a DevOps Testing Strategy?
A DevOps testing strategy must be focused on continuous testing. Testing cannot be DevOps or Agile unless it’s continuous.
Without continuous testing, there will be:
- Escaped defects.
- Late delivery of software.
- Unhappy customers.
Benefits of a DevOps Testing Strategy
Here are some benefits you can expect from a strong strategy.
Deliver Faster Feedback
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
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.
Reduce Test Execution Time Constraints
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 the best practices.
Best Practices For Developing a DevOps Testing Strategy
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.
Scale Test Automation
To build a successful strategy for DevOps testing, you’ll need to scale test automation — on web and mobile.
To Scale Web Testing
There are 3 ways organizations are scaling web testing today:
- DIY (e.g., Selenium Grid in-house).
- Containerized computing (e.g., using Docker and Selenium).
- Cloud (e.g., Selenium Grid with Perfecto).
To Scale Mobile Testing
There are also 3 ways organizations are scaling mobile testing today:
- Cloud testing labs (e.g., Perfecto).
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).
Automate All Testing Types
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.
Maintain A Stable Test Automation Suite
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.
Use Supporting Frameworks
Another important step for your strategy is to use supporting frameworks.
Here are some examples of where to use supporting frameworks:
- Provide a testing structure (BDD/ATDD) (Mocha, Jasmine, Jest, Cucumber).
- Provide assertion functions (Chai, Jasmine, Jest, Unexpected).
- Generate, display, and watch test results (Mocha, Jasmine, Jest, Karma).
- Generate code coverage reports (Istanbul, Jest, Blanket).
- Provide a browser or browser-like environment with control of scenario execution, UI testing, and more (Protractor, Nightwatch, Phantom, Casper, Selenium, WebDriver.io, TestCafe).
- Provide mocks, spies, and stubs (Sinon, Jasmine, enzyme, Jest, testdouble).
Rely on an Enterprise Class Lab
To release high quality fast, teams should rely on a robust lab:
- That can scale.
- That is secured.
- That is always available for all types of testing.
- That is up to date with all latest mobile and web platforms.
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.
Use Advanced Reporting and Analysis
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.
Use Headless Browsers
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.
Include the Full Team in Testing
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:
- Business testers to do exploratory and structured manual testing — utilizing codeless test automation.
- Software developer in testing (SDET) to create functional and non-functional code-based test automation scripts (via Selenium, Appium, etc.)
- Software developer to create unit and build acceptance tests.
Tools You Need to Succeed With Your DevOps Testing Strategy
