Summary

Adds a complete test suite and JaCoCo coverage tooling to the project. 57 tests across 13 test classes achieve 92% instruction coverage and 80% branch coverage.

Changes:

  • pom.xml: Added spring-boot-starter-test, Mockito 4.x, ByteBuddy 1.12 (JDK 11+ compat), JaCoCo plugin; fixed packaging from pom to jar
  • TopicServiceTest (17 tests): All business logic — CRUD, filtering, sorting, string ops, NIO file methods, stream operations
  • TopicControllerTest (7 tests): All REST endpoints via standalone MockMvc
  • GreetingControllerTest (3 tests): Default/named greeting, ID increment
  • HelloControllerTest (3 tests): Datetime, string ops, file ops endpoints
  • Model tests (13 tests): Topic, Customer, Greeting, Quote, Value — constructors, getters/setters, toString
  • SimpleTimeClientTest (6 tests): Date/time operations, timezone support
  • TimeClientTest (3 tests): Static/default interface methods, invalid zone fallback
  • CustomPredicateTest (3 tests): Functional interface with String and Integer predicates
  • ApplicationTest (1 test): Spring Boot context load with mocked RestTemplate
  • Test resources: H2 datasource config, temp.txt for stream tests

Review & Testing Checklist for Human

  • Run JAVA_HOME=/path/to/jdk11 ./mvnw clean test jacoco:report and verify all 57 tests pass
  • Open target/site/jacoco/index.html to confirm coverage meets 85%+ threshold
  • Verify the pomjar packaging change in pom.xml is acceptable (required for compilation)
  • Review TopicServiceTest assertions match actual TopicService behavior (especially findIdHavingCharacter which filters for 'g')

Notes

  • The Application class has a CommandLineRunner that calls an external REST API (gturnquist-quoters.cfapps.io). The ApplicationTest mocks RestTemplate and overrides this runner to avoid external calls.
  • Controller tests use standalone MockMvc (no Spring context) to avoid issues with the Application class's @Autowired JdbcTemplate and @Bean RestTemplate in @WebMvcTest context.
  • Mockito 4.x and ByteBuddy 1.12 were added as explicit dependencies because the versions bundled with Spring Boot 2.0.2 don't support JDK 11+.
