CoScriptor

Another nicely done tool from IBM......

While its concept is nothing new (think Web Marco tools like iMarco, Selenium etc), it adds in a few really nice touches.

1. Collaboration + Tagging => You can share and use script from others together with a standard tagging system. What really separates it is the private database that let you define/customise "variables"
2. Firefox integration => No need to startup a separate/additional program
3. Stored in easy to read text => the "source code" literally reads like a use case ..... can't wait to see its future integration with Rational tools. This flexible parser is probably the coolest touch.
4. Step run and running of script => Amazing done, with highlighting and direct script/web interface editing possible to accommodate any deviations. While Selenium does this too, CoScriptor is much narrower in its scope and hence able to do this more intuitively.
   

Firefox users should really give this a spin.
