Effects of Developer Testing

• Better team motivation
• Emphasis is on doing it right the first time - no
  flood of bugs
• Better team understanding test are good
  documentation
• Quality stays high
• Bugs are found early before they cause problems
• Developer tests are the software immune system
• Improved software design
• Solid unit level regression tests enables
  refactoring as needed
• Testable code is loosely coupled
• Schedule is shorter
• Without constant debugging rework you have more
  time
• Features and functionality are completed on time
  (or early)
• Lower development costs
• Lower initial development costs with early
  detection
• Lower maintenance costs going forward

Automation Lowers Costs

• Manual Developer Testing
• Typical JUnit tests have more code than the
  application under test
• More code for setup/teardown than for
  verification
• Static tests get stale as the code changes
• What developers do not think of when coding, is
  also not thought of when testing
• Automation in Developer Testing
• Lower cost ? higher adoption
• Covers more cases, even hard to imagine corner
  cases
• Tests stay current when the tested code changes
• Automated reporting, improving visibility,
  soliciting management participation
