It is a lightweight and free tool that supports both manual and automated tests. It can also be used to create and run custom tests.

Once installed, it is used to automate tests of any.NET and Java application. It can run both in-browser and in a headless mode. The tests can be distributed to the agents so that they run without being connected to the Internet, which makes it suitable for offline environments.

It allows the user to manage all test runs from a central server and, once the test execution is complete, it allows the user to view all the results. All the test files and the test results are stored in a server for later analysis.
