Testing the Stock Trader microservices

Now that we've learned how to build our microservices, the next important step, before deploying them to an OpenShift environment, is to first perform some unit tests on them to make sure they are working as desired.

Testing the frontend microservice

We can perform such unit tests by using locally installed Docker on our laptops. Let's run the Docker container we just built for Trader, and try it out:

jalcorn@Johns-MBP-8 portfolio % docker run -p 9443:9443 -e JWT_AUDIENCE=test -e JWT_ISSUER=test -e TEST_MODE=true trader:latest
