Automated Testing

• Advantages of automated testing:
  • Less tedium
  • Spot unintended consequences
• Important things to do:
  • Every method gets at least one test case
    • Ideally, there will be tests for every key aspect of its contract
  • Every time a bug is found, a test case must be added that checks for it
• Using JUnit
  • Download junit-4.5.jar
  • Make eclipse aware of it by editing build path to add an external JAR
  • Create a test class
    • Test methods should be annotated with @Test
  • Run the test class
    • Select "Run As JUnit Test" from the Eclipse green arrow
• Examples:
  • Sprite4Tester.java
  • StackDemo3Tester.java
