Can't see test summary

Hey,
Using my circleci yaml (same as documentation) I can’t seem to see test results in the end of each build:

Javascript Node CircleCI 2.0 configuration file

Check https://circleci.com/docs/2.0/language-javascript/ for more details

version: 2
jobs:
build:
docker:
# specify the version you desire here
- image: circleci/node:8.1.0

  # Specify service dependencies here if necessary
  # CircleCI maintains a library of pre-built images
  # documented at https://circleci.com/docs/2.0/circleci-images/
  # - image: circleci/mongo:3.4.4

working_directory: ~/repo

steps:
  - checkout

  # Download and cache dependencies
  - restore_cache:
      keys:
      - v1-dependencies-{{ checksum "package.json" }}
      # fallback to using the latest cache if no exact match is found
      - v1-dependencies-

  - run: yarn install

  - save_cache:
      paths:
        - node_modules
      key: v1-dependencies-{{ checksum "package.json" }}

  - run: mkdir ~/junit

  # run tests!

  - run:
      command: ./node_modules/mocha/bin/mocha --recursive --reporter mocha-junit-reporter
      environment:
        MOCHA_FILE: junit/test-results.xmll
      when: always
  - store_test_results:
      path: ~/junit
  - store_artifacts:
      path: ~/junit

Any ideas?
