Statement testing exercises, the potential executable statements in the code. Coverage is normally measured by the number of statements executed by the tests divided by the total number of executable statements in the test object. This is normally expressed as a percentage. In decision testing, decision tests, exercise the decisions in the code and tests the code that is executed based on the decision outcomes.
