Automated regression testing is now possible. RemoteLaunch will connect to your automated testing tools, allowing SpiraTest automation to manage all of your manual and automated testing activities. Automated test scripts can be used to run regression testing on applications to make sure that bugs are fixed or new features don't break existing functionality. They are often used in conjunction with manual testing, which is more efficient for testing new capabilities and features. Automated testing must be performed on a wide range of devices, browsers, platforms, and environments to ensure complete coverage. RemoteLaunch® and SpiraTest® allow you to manage the automated test process. You can track the automated tests against your project's requirements. This gives you a complete view of both manual and automated testing.

Serenity BDD makes it easier to write automated acceptance and regression test scripts that are more manageable and easy to maintain.

Serenity will tell you not only which tests were executed but also what requirements were tested. Serenity BDD has the advantage that you don't have to spend time building and maintaining your automation framework. Serenity's goal is to make it simple to quickly create well-structured and maintainable automated acceptance criteria using your favorite BDD or traditional testing library. You can work with Behaviour-Driven-Development tools like Cucumber or JBehave, or simply use JUnit. You can integrate with requirements stored outside (such as JIRA, or any other test case management tool), or use a simple directory-based approach for organizing your requirements.

The JCov open source project is used for gathering quality metrics related to the production of test suites. JCov will be open to allow the verification of regression tests being executed in OpenJDK. JCov's main purpose is transparency in test coverage metrics. OpenJDK developers will have the opportunity to use a code-coverage tool that is in 'lock step with Java language and VM development. This is why we promote standard coverage based JCov. JCov, a Java implementation of a code-coverage tool, provides a way to measure and analyze dynamic Java program code coverage. JCov allows you to see uncovered execution paths and method coverage. It can also show the source code of a program annotated with coverage information. JCov is most useful for testing to determine execution paths.

Reflect makes it easy to create regression tests and is easy to maintain. Reflect is a great tool for high growth teams to find bugs quickly and without slowing down their development speed. End-to-end testing shouldn't take too much time. Reflect the browser provides a better interface than a code editor. It's as easy as entering a URL, and then using your web application to create a test. Reflect records your actions and creates a repeatable test you can run as many times as you like. No installation required. Visual regressions (i.e., site-wide changes) can be detected with other website automation software. Visual regressions (i.e. bugs in the UI that do not affect the functionality of the site) are not possible with other website automation software. This is because automation tools operate at a lower level than users interact with your application.

An open-source Ruby Library for automating tests. Watir interacts the same way as a human with a web browser, clicking links, completing forms, and validating texts. It requires Ruby 2.6+, and Selenium 4, which was released just last week. It's been a very long road since Watir 6.0, which was released nearly 5 years ago. This version was a major reenvisioning of Watir’s default approach to automating, particularly as it related to Selenium. It was designed to combine Watir's original philosophy with the power and flexibility of Selenium. Watir 7, on the whole, is a more stable and performant implementation. WatirSpec can be used to test your gem code before requiring it. This will ensure that the code won't break anything else in Watir. Watir is tested on Linux using the latest versions supported browsers, and all active Ruby version. Coveralls is used to run Watir's code to encourage PRs. This ensures that all paths in the code are tested.
