We're developing an application and have earlier used manual testing. The manual test are written to make sure that the application fulfills the requirements document which is the base of the development.
The good thing with manual tests are that they can be written in parallell with the application development and the testing can begin as soon as the application is finished.
We would like to work in the same way but using automated tests. Has anyone any experience with writing automated scripts without the application that is to be tested?
As basis for the script we have the requirements and the HIS document (Human Interface Specification document) which describes how each window and dialog is supposed to look in the finished application.
