Java Testing Koans to understand how to write unit tests with JUnit.

• This is a Java 7 project.
• This is an Apache Maven project.

Additional exercises cover JUnitParams, Hamcrest, catchException and AssertJ.

• Run tests with mvnw test.
• You should see some test failures and errors (but there are no assertions).
• Go through the test code starting from Session 1:
  • All assertions are commented and incomplete.
  • Uncomment the assertions and complete them making the tests pass.
  • You can run individual sessions using mvnw test -Dtest=*1*
