Test Plan

Tests on hardware and software must always be in accordance with a documented test plan. The key point about a test plan is that it not only documents what will be tested, but also the expected results. In addition, a test plan can identify additional areas which should be tested and the resultant plan more comprehensive.

Having completed the tests, the results need to be considered and a determination of whether or not, any results have failed to meet an acceptable standard. In particular, each failure should be allocated a 'severity level'. Without this gradation, an objective view cannot be taken. See also System Testing and User Acceptance Testing.
