title: AWS CodeBuild Test Report Is Empty
body: <p>So I created and deployed a tutorial AWS CodeStar project [<a href="https://github.com/aamalik7196/Testv4]" rel="nofollow noreferrer">https://github.com/aamalik7196/Testv4]</a>. The files are created by AWS itself to run a simple Hello World sample project.</p>
  
  <p>the only change i changed is in the buildspec.yml file to create reports for testing as follows:</p>
  
  <pre><code>version: 0.2
  
  phases:
    install:
      runtime-versions:
        python: 3.8
      commands:
  
        # Upgrade AWS CLI to the latest version
        - pip install --upgrade awscli
  
    pre_build:
      commands:
  
        # Discover and run unit tests in the 'tests' directory. For more information, see &lt;https://docs.python.org/3/library/unittest.html#test-discovery&gt;
        - python -m unittest discover tests
  
    build:
      commands:
  
        # Use AWS SAM to package the application by using AWS CloudFormation
        - aws cloudformation package --template template.yml --s3-bucket $S3_BUCKET --output-template template-export.yml
  
        # Do not remove this statement. This command is required for AWS CodeStar projects.
        # Update the AWS Partition, AWS Region, account ID and project ID in the project ARN on template-configuration.json file so AWS CloudFormation can tag project resources.
        - sed -i.bak 's/\$PARTITION\$/'${PARTITION}'/g;s/\$AWS_REGION\$/'${AWS_REGION}'/g;s/\$ACCOUNT_ID\$/'${ACCOUNT_ID}'/g;s/\$PROJECT_ID\$/'${PROJECT_ID}'/g' template-configuration.json
  
    # post-build:
    #   commands:
    #     - echo In post build phase
  
  # only part added
  reports:
    TestReport: # CodeBuild will create a report group called "TestReport".
      files: #Store all of the files
        - '**/*'
  
  artifacts:
    files:
      - template-export.yml
      - template-configuration.json
  </code></pre>
  
  <p>the repo does contain a folder to perform a simple test. the build and deployment happens successfully [using AWS CodeStar] but when i go to see the reports tab its empty. i know for fact that the test ran as it is in the build log but the reports are empty.</p>
