    In order to strike the perfect balance between speed and quality, teams that hope to achieve Continuous Integration and Continuous Delivery must also implement Continuous Testing.

    This is often easier said than done. It’s virtually impossible to have your team running tests at every moment — they do have lives outside of work after all, and it can be difficult to put dinner on the table while running a Selenium script at the same time. So how do you run your scripts, even if you aren’t at your desk?

    Fortunately, there are various hands-free options for continuous testing that you can implement, which will keep tests running for you while you eat, sleep, or maybe even get some exploratory testing done.

    Why Continuous Testing

    What’s the point of continuous testing? There are a few major advantages that will enable you to achieve more in your day-to-day.

    • Test while you sleep – With continuous testing, you can literally test in your sleep. By setting tests to run overnight, you can experience the luxury of coming in the next morning to have your test results waiting for you and knowing with a glance whether they passed. Just ask America’s Test Kitchen about how convenient it is.
    • Keep up with Agile, DevOps and CI/CD – When software development teams are constantly integrating, you need a testing strategy to ensure those new features, fixes, and changes are put through the quality process, no matter how frequently they’re implemented. Continuous Testing is the only way QA teams can keep up with constantly changing features, frequent integrations, and fast workflows.
    • Catch bugs in each regression – When there are constantly small changes to an application’s code, it can break something that was previously functioning. And you don’t want your customers to be the one to catch it. Continuous Testing will help you be first to spot new bugs, so you can quickly debug and release to users with confidence.
    • Level up your automation game – Automate your automation with continuous testing, and set your tests to run as often as you need. Then come back to test results or screenshots that tell you exactly what you need to know about the health of your applications. Plus, testing in parallel allows you to further accelerate Continous Testing to increase browser coverage without compromising runtime.

    Continuous Testing With a CI Server

    Selenium WebDriver has long provided teams with the ability to automate tests across browsers. But in order to run those tests continuously, a Continuous Integration tool such as Jenkins, VS Team Services, Buildbot, Bamboo, CircleCI, TravisCI, Codeship, or TeamCity is needed.

    By far, the most popular option is Jenkins, an open source automation server written in Java. In fact, according to the SmartBear 2018 State of Testing Survey, 66 percent of participants choose Jenkins to be their CI server. For development teams adopting Agile and DevOps workflows, Jenkins is a reliable tool for continuous integration and delivery.

    But what about testing teams that want to leverage Jenkins for Continuous Testing with Selenium? The CrossBrowserTesting integration with Jenkins lets you run automated functional tests with Selenium, Appium, and visual screenshot tests, which means that every time you run your build process, you can simultaneously run your testing suite across thousands of browsers.

    This is ideal for teams that already work with Selenium and a CI tool for deployment to start testing on a continuous basis. While Jenkins tends to be the most popular choice for CI and automated test scheduling, CrossBrowserTesting also integrates with TeamCity and VS Team Services, so no matter what tools you’re already using, it’s easy to integrate CrossBrowserTesting into your current workflow.

    Continuous Testing With a Record and Playback Tool

    For teams that may be less familiar with Selenium but still wish to automate, a record and playback tool might be a more practical option.

    Record & Replay enables teams to achieve automation across browsers, just like they would with Selenium, without requiring knowledge of scripting and frameworks. This has provided teams with a more accessible option for less technical team members, or those who are just getting started with automation, to create automated tests. As tools like Selenium IDE and its alternatives are brought back into the spotlight, these options are becoming more and more attractive to modern testing teams.

    But where record and playback tools will normally only run the test once to check if the test passes, how can testers implement Continuous Testing?

    With new Scheduling in CrossBrowserTesting, you can schedule a Record & Replay suite to run as often as you need them. For organizations that have less technical testers, this allows you to achieve continuous testing without requiring the skills to run Selenium and Jenkins or another automation server.

    Continuous Screenshot Testing

    Teams that solely focus on functional testing without incorporating visual testing will be disappointed when all their tests pass and users are still pointing out visual bugs.

    When visual elements can change from browser to browser or device to device and make the user’s experience difficult or impossible while still functioning correctly, it’s important to run compare screenshots in regression. Comparing these pages side by side and with their historical versions means you can be more aware of changes that break the application in order to debug before they reach the end user.

    While you could always run automated screenshots in CrossBrowserTesting, it required a manual motion to rerun those tests on a certain cadence. You can now set those screenshot tests to run with the new Scheduling feature, just like you can with Record & Replay.

    Continuous Testing for Every Team

    No matter what tools you’re already using, what technical level you’re at, or how far your team is in their test automation journey, there are options to help every team achieve continuous testing in CrossBrowserTesting.

    With options to schedule tests with Selenium, Record & Replay, and automated screenshots, you can take your automation to the next level and receive test results through email or Slack on a daily, weekly, or monthly basis that you decide.
