We know it: most people prefer to use pen and paper or a whiteboard to make software mockups because “it’s the fastest way”.
Well, if you count the time it takes to transfer the mockup from paper to a digital image, we think Balsamiq Mockups is faster, not to mention much easier and, dare we say it, more fun!
We optimized the user interface for speed: fewer buttons, more keyboard commands, full undo/redo, object snapping...you name it.
TestLink is a open source web based TEST MANAGEMENT and test EXECUTION system under the GPL license (i.e. free to use). The tool enables quality assurance teams to create and manage their test cases as well as organize them into test plans. These test plans allow team members to execute test cases and track test results dynamically, generate reports, trace software requirements, prioritize and assign.
The tool is based on PHP, MySQL, and includes several other open source tools. We support interface to Bug tracking systems as is Bugzilla or Mantis.
