Hi all,

I'm a newbie to software testing and planning to do a course on the same. I was going through the testing syllabus content of an institute in india and they say about 4 testing techniquies
1)Black box
2)White box
3)Incremental
4)Thread

I went through some testing tutorials and have a rough idea about the first two. Can some one give me an idea about the 3rd and 4th type of testing techniques? Also please help me in finding some good video tutorials which as a beginner in software testing would be helpfull for me in preparation.

Thankyou all in advance
