Off the top of my head:

• Unit testing in the sense of "testing the smallest isolatable unit of an application"; this is typically a method or a class, depending on scale.
• Integration testing
• Feature testing: this may cut across units, and is the focus of TDD.
• Black-box testing: testing only the public interface with no knowledge of how the thing works.
• Glass-box testing: testing all parts of a thing with full knowledge of how it works.
• Regression testing: test-cases constructed to reproduce bugs, to ensure that they do not reappear later.
• Pointless testing: testing the same basic case more than one way, or testing things so trivial that they really do not need to be tested (like auto-generated getters and setters)
