3. Theansweris... Spock!

4. WhyGroovy and Spockfor a Java developer? Groovy powerfulsyntax codeless and do more Spock BDDstyletesting describe featuresthroughexecutablespecifications documentation and examples of legacycode Integrateswith Spring & DbUnit RunswithJUnit 4 => Maven, CI

5. Extendspock.lang.Specification classBankDaoSpecextendsSpecification Define a feature (test) method def “finds a bank by id"() { // blocks for 4 test phases setup: when: then: } HOW DO I TEST?

6. Featuremethod blocks 4 test phases in blocks Setup => setup: / given:/ where: Execute => when: / expect: Verify => then: / expect: Teardown => cleanup: and:

7. Data-driventests Withwhere block where: bankName << ['BPH', 'BOS', 'HSBC']

9. Use Spring DI (@Autowired, @Resource)

11. Wrapper for DbUnit

12. Spring integration – was useful whenSpring TestContextwasnotyetimplemented
