Bingo for meetings- dockerize tests–part 9

Bingo is a small project, written in TypeScript , and developed with Alexandru Badita in launch break (one hour - more or less). You can find sources at . Those are my blog posts for Bingo : ( scroll below for the post)

(Now the actual blog post for Bingo Meetings project)

We have now full DDD and tests that should be run for the objects. However, we need a way to automatically have the tests run . The

easy way is to dockerize the tests – run in a container, grab the results, display somewhere.

First we should have the tests display in a nice form some data.  For this, jest have the “reporters” features – but no documentation . So I try to find and .


So what are the steps ?

  1. Create docker from node
  2. Copy sources ( add a .dockerignore to not copy node_modules)
  3. Install dependencies
  4. Run test
  5. run image  into container and grab the tests results


The docker file , named docker_ci_test.txt , has the following content

FROM node:8
COPY . ./
RUN yarn
RUN yarn test –reporters default jest-stare
CMD tail -f /dev/null

The bat that runs the image and grab results from the container

docker build ../src -f docker_ci_test.txt -t bingo_ci_test
docker run -d –rm –name bingo_ci_test_container bingo_ci_test
docker cp bingo_ci_test_container:/app/jest-stare .
docker container kill bingo_ci_test_container

Feel free to download the project from  and run the ci_test.bat file from dockerize folder.
