Identifying and fixing software flaws early in SDLC is much more effective than doing so after release. With the right continuous testing solutions, IT professionals can easily detect and resolve software issues before they escalate into greater problems and businesses can ensure faster time to market and eliminate potential re-engineering costs. 

In this guide, we’ll briefly explain what continuous testing is and outline the top seven tools supporting this approach.

Key Takeaways

  • Understand the concept of continuous testing 
  • Explore our continuous testing tools list
  • Review the technical attributes of each solution
  • Learn how to get started with the instruments listed
  • Discover when to use each continuous testing tool

What’s Continuous Testing?

Continuous testing is an Agile and DevOps practice, where developers and QA testers execute automated tests from the beginning of development — all the way through to deployment. This approach lets programmers catch bugs early enough in the process and refine the performance of their code accordingly. In the longer perspective, continuous testing expedites software delivery and incurs fewer expenses — all without jeopardizing solution quality and user experiences. But for this practice to be truly effective, it needs a solid basis: specialized continuous testing tools.

Popular Continuous Testing Tools for Your Project

Although versatile solutions are accessible on the market, the truth is, there’s no one-size-fits-all continuous testing instrument. When considering a testing framework for your current project, focus on the types of functional and non-functional testing it supports, how well it integrates with your current tech stack and CI/CD workflow, and which platforms and devices it covers. Check our continuous testing tools list to come up with the right system for your needs:

Selenium

https://www.selenium.dev/selenium-ide/

Selenium is an open-source ecosystem for web application testing that comprises:

  • Selenium IDE — supports the creation of test cases and automated scripts without significant coding skills
  • Selenium WebDriver — allows for writing reliable website test suites that perform solidly across OSs, browsers, and devices
  • Selenium Grid — enables running several WebDriver scripts simultaneously for quick test execution

Key features of Selenium:

  • Cross-environment testing due to compatibility with various OSs (Linux, macOS, Windows) and browsers (Firefox, Google Chrome, Safari) 
  • Support for different languages (C#, Python, Ruby, Java, JavaScript)
  • Integration with CI/CD tools (Jenkins, GitLab, Azure DevOps, CircleCI)
  • Support for testing cloud-hosted web applications
  • Integration with cloud-based testing platforms (Sauce Labs, CloudTest, BrowserStack)
  • Extensive community with valuable resources 
  • Customization and extensibility

How and when it’s best to use Selenium

If you want to try this free platform, first install a programming language library along with a package manager. Next, set up Selenium WebDriver with its dependencies and download a browser driver. Upon these simple steps, start creating a test script. 

Selenium is the best option for functional automated web testing, including regression, user acceptance, smoke, sanity, exploratory, compatibility, and UI testing. 

Appium

https://www.automationtestinghub.com/appium-inspector-tutorial/

Appium is a non-proprietary test automation framework used for native, cross-platform, and hybrid mobile applications, while also offering basic support for web and desktop platforms. Its core parts are:

  • Appium Core — functions as a server and API to foster communication between test scripts and the targeted application 
  • Appium Drivers — connect the tool to specific platforms, OSs, and devices 
  • Appium Clients — create automated test scripts in the desired language
  • Appium Plugins — alter the instrument’s functionality 

Key features of Appium:

  • Support for JavaScript, Java, Python, and C#
  • Operation across platforms (iOS, Android, Windows)
  • Compatibility with Jenkins, Bamboo, and other CI/CD solutions
  • Support for testing cloud-hosted mobile systems
  • Integration with cloud-based testing platforms
  • Customization and extensibility

How and when it’s best to use Appium

To take advantage of Appium-driven testing, install the solution and a driver for your intended platform. Then, set up a client library in your preferred language and add any required plugins. 

This continuous testing tool is an ideal fit for performing functional testing of mobile applications: cross-platform, UI, sanity, regression, compatibility, and smoke.

Apache JMeter

https://www.redline13.com/blog/2021/04/running-a-jmeter-load-test/

One of the most effective continuous performance testing tools  in CI/CD pipelines is Apache JMeter. This free solution is perfectly suited for performance testing of web applications, services, protocols, database servers, and APIs, and can be augmented with tailored performance testing services. Using JMeter, technical specialists effectively gauge the way software operates under different loads; validate its response times, latency, reliability, and scalability; and quickly spot and correct issues.

Key features of JMeter:

  • Feature-rich Test IDE
  • Integration with CI/CD tools (Maven, Gradle, Jenkins)
  • User-friendly interface
  • Compatibility with Windows, Linux, and macOS
  • Extensibility, including data analytics and visualization plugins and scriptable samplers

How and when it’s best to use JMeter

To start using this tool as soon as possible, download it from the official provider and install it on any OS compatible with Java. Then, create a test plan with the Test IDE.

JMeter is an excellent pick when multiple kinds of CI/CD automated performance testing are needed

Jenkins

https://www.jenkins.io/blog/2016/04/11/run-your-api-tests-continuously-with-jenkins-and-dhc/

Next in our continuous testing tools comparison is Jenkins, an open-source server employed in CI/CD workflows to automate software creation, testing, and deployment. While not a testing framework at its core, this server triggers and orchestrates tests built with tools akin to Selenium. If you want to validate APIs or web, cloud, mobile, or desktop platforms, Jenkins adeptly controls test execution, ramping up the release of your system.

Key features of Jenkins:

  • Extensibility for CI/CD projects
  • Integration with testing frameworks (Selenium, Appium, JMeter)
  • Compatibility with numerous platforms and OSs
  • Support for parallel testing 
  • Huge plugin ecosystem integrable with version control systems, containerization platforms, and other DevOps solutions
  • Large and active community

How and when it’s best to use Jenkins

If you’d like to get started with this instrument, install at least Java JDK 11 and download the generic Java package from the official website. After that, start Jenkins on your device and finalize installation through your browser. 

It’s best to use this solution for unit, API, integration, regression, UI, performance, smoke, sanity, load, and cross-environment testing across any platform — depending on the testing framework used and your specific needs.
