Can anyone explain white box and black box testing?
I have also seen Alpha, Beta ... testing in the marking scheme. What is that?
Click to expand...

to explain white box and black box testing think of the entire system as a "box". In white box, you input data and see if the output is as expected. if not, you go thro the code and de-bug it. so in this case the box is transparent i.e the code is taken into consideration when testing.
In,black box, you just input data and see what the output is and the code is not taken into consideration here so here the "box" is thought of as "opaque"

This is how black box and white box was explained to me.....
If i get a better definition,ill let u know...
hope u understand this though

Alpha and beta testing are simple concepts. Alpha is done by the software devs ,who test the system and de-bug it ,and beta is done by the end use/client, (sort of like how win 8.1 was released to the public as a "beta version".) If the end user comes across any errors,etc they wud report it to the devs.
