Test As You Go

Combining testing with version control only works if you're continually writing tests.

• If all the little pieces work, there'll be less pain putting them together

• Best tests come when the problem is fresh in your mind

• If you don't like testing, best to do it in small doses
  • Avoid the big, dull testing swamp at the end

• You won't be tempted to skimp on testing at the end of the project

• The code is always at high quality
  • Good for project visibility, no bug hunt at the end
  • Means you can make partial releases (incremental development)

• Gives instant feedback

• Ferret out design problems early

• Keeps your code testable and well formed
