Hello,

I know it seems like a dumb question but I'm trying to familiarize myself with testing apex code with apex language.  

I am unsure when to use system.assertequals(x,y), system.assert(condition) and system.assertnotequals(x,y) and I have noticed it being used quite a bit.  I've looked at the user guide and and this link http://wiki.developerforce.com/index.php/An_Introduction_to_Apex_Code_Test_Methods, but still require more of a plain english explanation on when and why these methods are used.

Can anyone help me on this.

Much thanks!
