Tesly is a web-based test plan management system that allows you not only to store and track the results your test cases, but also to share the testing responsibility among members of your team. After creating your team, you can assign test cases to be executed by your team-mates, who will receive a notice of the test case assignment via email. Every time a test case is executed, you will immediately get the results of that test run via email. When you come back to the site, you'll be able to see at a glance the status of your testing, as well as review the history of testing activity.
Tesly is provided both as a hosted service and as a licensed product you can install on your own server. The hosted Tesly service has both free and paid subscription levels. With your free account you will be able to manage one project and have as many people as you wish on your team. Your team-mates will be able to see all the test documentation that you create, and you can assign tests to particular individuals or just make them available for others to view and run. If you wish to manage more than one project, or if you'd like to have the ability to create attachments and track issues, you can create a paid subscription.
