Project Management Methodology and Unit Testing

Unit testing is checking computer code which has been written to ensure each individual component is checked to ensure all inputs produce their desired outcomes.

Unit tests should be created as each component is written and kept upto date then as the code is enhanced as time progresses.

When unit testing progams, consider and document;

• Never believe you will not make mistakes, in fact assume, by default you will, then test you did not.
• Take time to test each individual component.
• Test line by line, function by function, component by component.
• Use unit testing tools and processes to ensure a level of automation in your testing as less things will be forgotton.
• Ensuring a full unit testing saves a considerable amount of rework post delivery of the code.
• The hardest code faults to find are sometimes where you did something obvious, as you wont think to check the obvious.
