title: How to run my unit tests in github action workflow?
body: <p>So I developed a few tests for my Android app and I need to run the tests using github actions workflow. Here is my .yml file, but I don't know how to run the tests( and get their logs):</p>
  <pre><code>name: Java CI with Gradle
  
  on:
    push:
    pull_request:
      branches: Features
  
  jobs:
    test:
      name: Run Unit Tests
      runs-on: ubuntu-18.04
  
      steps:
        - uses: actions/checkout@v1
        - name: set up JDK 1.8
          uses: actions/setup-java@v1
          with:
            java-version: 1.8
        - name: Unit tests
          run: bash ./gradlew test --stacktrace
        - name: Unit tests results
          uses: actions/upload-artifact@v1
          with:
            name: unit-tests-results
            path: ./app
  </code></pre>
  <p>I'm not sure how to run all the app and then run all the tests, can someone give me a hint? I searched all the internet, I came across this code, but it doesn't work. My artifact is the whole app itself
  The tests are: <br>
  1.SignUpTest.java <br>
  2.SignInTest.java <br>
  3.AddToCart.java <br></p>
