What Is Continuous Testing?

Continuous testing is a software testing methodology that helps identify and address risks at all stages of the development pipeline. In other words, it means testing all potential code changes as early as possible. The goal of continuous testing is to minimize business risk and impact on users. 

As the impact of software became bigger and bigger over the years, the expectations of quality grew with it. Continuous testing became a useful tool to address the faster release cycles in order to combat any issues along the development process. Today, continuous testing is considered a standard part of the testing strategy of organization that knows the importance of delivering quality in a timely manner.

What Is DevOps Continuous Testing?

DevOps continuous testing means the same thing: testing code changes as early and often as possible. Continuous testing plays an important role in DevOps — and testing continuously is important for all DevOps teams.Testing in Continuous IntegrationTesting in Continuous Integration (CI) is an important step of the process. Automating tests and testing continuously helps ensure rapid delivery. 

Why Continuous Testing Is Important in DevOps

Continuous testing is important in DevOps to:

  • Improve quality.
  • Accelerate releases.
  • Reduce costs.

Automated tools help software developers make better release decisions with in-the-moment feedback about critical software defects. Continuous testing in Agile reduces costly manual testing. It balances the demand for quick delivery of features with high-quality code.

By treating test code as if it were production code, faulty code rarely finds its way into a production environment. Before software is ready to be released into the wild, testing continuously can give software vendors confidence that code changes will have maximum impact with minimal risk to their business' bottom line.

10 Continuous Testing Benefits

Continuous testing comes with many benefits. Here is an overview of the top 10 continuous testing benefits (with more information on each benefit below).

  1. Enables faster delivery of web and mobile apps.
  2. Allows for higher-quality code.
  3. Eliminates the testing bottleneck in DevOps.
  4. Provides useful, risk-based feedback.
  5. Allows for smarter release decisions.
  6. Continuous testing is more Agile.
  7. Creates a reliable and consistent testing process.
  8. It’s more efficient testing.
  9. It gives a more stable user experience.
  10. Enables integrated teams rather than siloed teams.

Risk-Based Feedback

Testing continuously helps ensure software features are ready for primetime well before release. Actionable feedback helps developers and managers discover and fix critical defects while code is being built, not afterward.

Risk-based insights from automated tools help cast a much wider safety net for business risk coverage than traditional (and time-intensive) manual testing.

 Instant feedback also helps developers make better design decisions in the moment — giving managers all the data they need to properly assess a release.

Smarter Release Decisions

Agile, DevOps, and Continuous Delivery have shortened the timeline for design, development, and delivery of software updates. Releases occur as quickly as every two weeks to 1,000s of times per day.

To stay competitive and deliver features customers want, it is increasingly necessary to use automated testing to keep up with accelerated release processes. Without thoroughly understanding business risk, poorly-vetted release candidates can cause more harm than good. 

Risk-based feedback using a continuous testing tool can help developers decide when and how to release new changes. Automated tools are helping more and more companies find a balance between increased code complexity and the demand for faster application delivery.

More Efficient Testing

Continuous testing benefits developers and managers by helping them conduct the right tests at the right times — allowing them to determine whether a shift left or a shift right is necessary in their delivery pipeline.

End-to-end testing with automated tools helps cut out the false positives and timeouts often seen in standard test environments. When testing is done at each stage of software development, developers can be confident they’re building a secure, highly-flexible framework.

This cuts out redundancy and saves valuable time. So, continuous testing ensures software companies have the strongest architecture in place for the future expansion of their applications — especially as users demand new features.

More Stable User Experience

One of the most important aspects of continuous testing is ensuring faulty code doesn’t reach users and disrupt their experience. Software developers must find a balance between delivering new features that users want while not disrupting the experience they’ve grown to love.  

Since software has become the primary method for connecting businesses with customers, one poor user experience can be counted as a business failure. 

In-depth testing ensures that all aspects of the user experience are preserved and accounted for. This helps maintain a vendor's brand and reputation once their software is ready for primetime.

Integrated Teams

Continuous testing helps ensure that each team member in the development pipeline works effectively and efficiently together. Long gone are the days of handing off production-ready code to siloed QA testers.

Since quality is assessed at all phases of the software development cycle — not just at the end — teams are better integrated and more aware of each step of the pipeline.

Today, software companies rely on continuous testing to ensure high-quality code is being built the moment development teams start to code.

5 Steps For Continuous Testing in DevOps

Here's how to do continuous testing in DevOps in 5 key steps.

1. Establish Stable Automation

The first step on the path to testing continuously is to establish stable automation. You'll have stable automation once:

  • All testing issues have been remediated.
  • Smart reporting clearly discerns between real issues and false negatives.

A key consideration in automation testing is a team’s skillset. Assess the experience level of your team so you can determine whether code-level scripting such as Selenium, Appium, or even Espresso/XCUITest makes sense.

Otherwise, you may want to select a codeless or low-code solution. If you choose a tool that does not match your team’s skillset, you will struggle to reach stable automation.

2. Run a Daily Cycle

Your next phase is to add a limited amount of scripts into a repetitive pattern that run at least once a day — automatically, unattended, and successfully on more than a single platform (mobile and/or web).

Note: you can't move forward unless you have your test scripts running robustly with little to no false negatives. When you are running with minimal false negatives you demonstrate to your organization that you have a reliable automation process.

This trust is a crucial milestone in the path to testing continuously.

3. Increase Coverage

Once stable automation is running reliably, the next phase is increasing test coverage.

Numbers can vary. The ultimate goal is to reach valuable and meaningful functional and non-functional test automation coverage. The actual coverage number may be 95% or even 90%. But remember, everything not automated will occur only at the end of the cycle, which impacts speed.

In this stage, focus on a low-maintenance yet up-to-date lab. Your lab should support scaling up. You will need dozens of concurrent exactions as well as smart reporting to filter the noise from the true failures.

4. Reach 95% Coverage

In the next step on the path to testing continuously, you strive to reach 95% coverage. To do this you will need additional layers of environment control and capabilities such as:

  • Network virtualization.
  • Service virtualization.
  • Sensor mocking.

In addition, you’ll need high-value, high-trust testing to run reliably from your CI. This will allow you to meet the continuous delivery maturity goal.

At this stage, your team will run dozens of concurrent executions. And your reporting needs to be able to scale to millions of lines of actions, huge amounts of data, screenshots, videos, and more. Also be aware that ineffective reporting solutions tend to break at this stage.

5. Do Continuous Testing Multiple Times/Day

The final stage is continuous testing.

At this stage, the process moves from automated testing “each night” to “multiple times a day”(CI/CD). The benefit of this is even faster feedback, more accuracy, and minimized risk.

Continuous delivery mandates this stage. This gives you even more flexibility during the development cycle and usually cuts defects fixing time by 50%.

How to Achieve Continuous Testing

What You Need in Continuous Testing For DevOps

Your DevOps continuous testing platform needs to be able to handle 4 stages: test creation, execution, lab setup, and analysis. Each of these stages must mature significantly for DevOps. 

Test Creation

Test creation needs to shift from being the most manual and time-consuming stage to simpler, high-coverage test automation.


Test Execution

Test execution cannot scale before it is robust and covering ample functionality. Once it scales, teams need to focus on increasing the platform coverage. Successful test execution can grow beyond  25+ permutations that run in parallel concurrently to reduce the overall execution time.


Testing Lab

The testing lab component is possibly the most important pillar for success. When the lab is unstable, outdated, and cannot support hundreds of concurrent executions across different mobile/OS permutations, continuous testing is slow and flaky. Mature DevOps relies on a lab that can support this exact level of scalability and elasticity.


Teams cannot move fast enough when they have no abilities to quickly analyze test results and filter noises among huge piles of test data. Mature CT in DevOps depends on being able to get quality visibility, analyze root cause analysis of issues, and optimize the overall quality activities in the pipeline.
