Hi,
I am new to Salesforce testing.When I try to push a trigger class it says your code coverage is below 75%.I need to deploy it urgently.I tried running all tests and by going to developer console to check code coverage for each class.
Here is the screenshot


I am thinking if I could exclude the classes with miminal coverage from the code coverage so that they do not lower the overall code coverage.I tried that by annotating each class by @isTest but even after that when I tried run all tests and went to develop console I could still see those classes with 0% coverage.
