About this repo

This is a minimal "Hello World" type webapp built with Spring Boot.

Command	What it does
`mvn compile`	Should result in a clean compile
`mvn test`	Runs JUnit tests on the code base
`mvn test jacoco:report`	Runs JUnit tests, and if all tests pass, computes code coverage. The code coverage report (Jacoco) can be found in `target/site/jacoco/index.html`
`mvn test pitest:mutationCoverage`	Runs JUnit tests, and if all tests pass, runs pit (pitest.org) mutation testing to measure effectivness of test suite
`mvn package`	Builds the jar file `target/gs-spring-boot-0.1.0.jar`
`mvn spring-boot:run`	Runs the code to startup a web server. Access it via `http://localhost:8080` on the same machine where the server is running. Use CTRL/C to stop it.
`java -cp target/hello-1.0.0.jar edu.ucsb.cs156.spring.hello.Application`	If done after `mvn package`, runs the code to startup a web server.
`java -jar target/hello-1.0.0.jar	If done after `mvn package`, this is another way to start up the web server.

The code in this repo is in support of jpa02 for Fall 2022 for CMPSC 156.

The code in this repo is based in part on the tutorial here: https://spring.io/guides/gs/spring-boot/, and the code here in the complete directory of this repo https://github.com/spring-guides/gs-spring-boot.git.

That code has been modified for use in UCSB CMPSC 156 as described below.

Java 17 support
- Converting pom.xml to use Java 17
JUnit 5
- Converting test code to use JUnit 5 instead of JUnit 4
Heroku Support
- Ensuring that the PORT environment variable is used to define the port on which Spring Boot starts the web server
- Providing a Procfile for deployment on Heroku
- Added a system.properties file in the main directory which specifies the Java version for Heroku.
Testing and CI
- Adding JUnit tests
- Adding jacoco as a plugin to measure test case coverage
- Adding pitest for mutation test coverage.
- Adding support for GitHub Actions to run the test cases, compute jacoco report, upload code coverage reports to Codecov.io, and produce pitest artifacts.
