The airport parking lot calculation tool raised the attention of some managers. There seem to be too many bugs in the application. Since they want to have it re-written, write a regression test suite based on the old application, which may be executed against the new application as well. Assume that the same interface will be kept. Use RobotFramework for your automated tests.
As an oracle for your automated, use the rates mentioned on the official website: http://www.grr.org/ParkingRates.php
We prepared three example tests in RobotFramework that may get you started. Please find these examples at http://www.shino.de/ewt19/ewt19_parkcalc.zip
Please submit your test descriptions (the text files) alongside with any additional resources needed to run them with robot framework and the selenium library installed (that may include code as well).
