Integration Test Coverage with jacoco-maven-plugin

Integration Test Coverage with JaCoCo - Presentation Link

This is an example project showing how to generate coverage reports for integration tests run against a remote server. The server will be run in docker, and the integration tests (written in Cucumber) will hit the remote urls.

Pre-requisites

1. Docker
2. Maven
3. JDK 8

Module Layout

server

Simple spring boot application that manages contacts and phone numbers backed by a postgres database
NOTE - requires postgres db running locally if server is running in IDE. To run, spin up a docker container just for postgres with command

docker run -p5432:5432 -i -t postgres:9.6.7

integration-tests

Integration tests written with Cucumber BDD

multi-module-server

Same as the server module, but broken into separate modules for web and persistence layer

Running int test coverage

1. Build the server module and run docker image

   cd server
   mvn clean package
   docker-compose build
   docker-compose up
   

2. Run the integration tests (in a new terminal)

   cd integration-tests
   mvn clean test -Pone
   

3. Stop server (in same terminal docker-compose up was run)

    Ctrl^C
    docker-compose down
   

4. Examine results in integration-tests/target/coverage-report/html

Running test test coverage with multi-module-server

1. Build the server module and run docker image

   cd multi-module-server
   mvn clean install -f modules/pom.xml
   mvn clean package
   docker-compose build
   docker-compose up
   

2. Run the integration tests (in a new terminal)

   cd integration-tests
   mvn clean test -Pmulti
   

3. Stop server (in same terminal docker-compose up was run)

    Ctrl^C
    docker-compose down
   

4. Examine results in integration-tests/target/coverage-report/html
