I just finished my third selenium hobby project. The program that I have done was quite big and took a long time, with a lot of multithreading and coding. The program is basically a "cheap flights" program, where you pick a place you want to go (Hawaii for example), and when (2015-12-02 to 2015-01-01). The program then goes to 20-30 different airline companies and returns the cheapest or/and the fastest tickets.
This was very fun and I learned A LOT. Do you guys have any tips on more fun projects/programs you can do with selenium? Maybe anything fun that you have done with Selenium, beside test case automation?
