JUNIT OR TESTNG? Please Mention what videos to skip?

Hi

I have enrolled for selenium training videos. I know there are 45 Modules or videos. As Ashish(selenium Trainer) had mentioned in
his training videos that we can either skip JUNIT OR TESTNG.

[color=#FF0000:2h51p6vg]Please mention which video I can avoid

1) If I want to skip JUNIT

2) iF I want to skip TESTNG

This would help me prepare for Selenium soon

Thanks
