how to run (using docker)

using docker

1. docker pull maven - pulls the latest maven image docker run -it --name my-maven-container maven bash interactively runs container based on this image and execute a command shell inside (in case this container is already running docker exec -it my-maven-container /bin/bash)

2. cd - changes the active directory to one of the current user (supposed to be root)

3. git clone https://github.com/ksiv/junit-run-from-application.git - pulld repo to current folder. git command is present in the latest image I checked with.

4. cd junit-run-from-application

5. mvn package - downloads all dependencies and compiles test class and our executable app

6. run java -classpath "./target/test-classes:/root/.m2/repository/org/junit/platform/junit-platform-engine/1.10.1/junit-platform-engine-1.10.1.jar:/root/.m2/repository/org/junit/platform/junit-platform-launcher/1.10.0/junit-platform-launcher-1.10.0.jar:/root/.m2/repository/org/junit/platform/junit-platform-commons/1.10.1/junit-platform-commons-1.10.1.jar:/root/.m2/repository/org/junit/jupiter/junit-jupiter-engine/5.10.1/junit-jupiter-engine-5.10.1.jar:/root/.m2/repository/org/junit/jupiter/junit-jupiter-api/5.10.1/junit-jupiter-api-5.10.1.jar:/root/.m2/repository/org/junit/jupiter/junit-jupiter-params/5.10.1/junit-jupiter-params-5.10.1.jar:/root/.m2/repository/org/opentest4j/opentest4j/1.3.0/opentest4j-1.3.0.jar" example.runner a
