Check out this recent webinar, its really helpful and every minute is worth it.
You should subscribe to the Salesforce Developers YouTube channel. It has several webinars on Apex Testing from various events like DreamForce etc. which are far more useful and time saving than reading several PDFs and gaining a little.

Single action
Test to verify that a single record produces the correct, expected result.

Bulk actions
Any Apex code, whether a trigger, a class or an extension, may be invoked for 1 to 200 records. You must test not only the single record case, but the bulk cases as well.

Restricted user
Test whether a user with restricted access to the sObjects used in your code sees the expected behavior. That is, whether they can run the code or receive error messages.

Positive behavior
Test to verify that the expected behavior occurs through every expected permutation, that is, that the user filled out everything correctly and did not go past the limits.

Negative behavior
There are likely limits to your applications, such as not being able to add a future date, not being able to specify a negative amount, and so on. You must test for the negative case and verify that the error messages are correctly produced as well as for the positive, within the limits cases.

Test Methods
Apply testMethod or @isTest to methods
      • Demarcates a single self-contained test
      • Signature characteristics:
