Thread: How to test all files in a folder

Im doing some junit test. I have a bunch of files in a folder and have to test each one. Some of them freeze during the process that why i added the time out. I wanna do a loop to add all the files to the array and the run the test. As I have it now I have to put what indexes of the list i want to test manually. I tried doing a for loop but it tells me that the method is static and i cant add the files that way.
Thank you in advance...
