This repo is to show how you can take a simple Liberty application and use Testcontainers to run all your tests in a container.
- Java 11
- Docker Desktop
- Maven
First you will need to manually build your docker image. I have provided you with a Dockerfile in the /start directory you can use for creating your image. Firstly you need to package your application with the command mvn package from the /start directory.
Once the build is finished you need to build your docker image with the following command docker build -t testcontainers:test .
You can see if your image has been created by running docker images and look for the testcontainers:test image
Now that has bee created you can start testing your application
You can do this either by running Liberty in devmode and pressing enter once it is up and running by using the following command mvn liberty:dev. Then simply pres the return key and your tests will run.
Alternativly you can use the maven failsafe plugin to run your tests by running the following command mvn verify
Now you should see some output in your terminal in regards to the container being started and your tests all running again the endpoint in the container.
