Pull the latest frommain andcreate a new branchstep2

git checkout maingit pullgit checkout -b 'step2

Before we continue, let’s create an account and set up our repository onCodecov

Create a Codecov account

Create an account on Codecov through oursignup page. We willConfigure Codecov for our demo repository in the next steps, for now just make sure your groups and repositories are syncing.

Set up theTeam Bot, make sure theRole allows the team bot to comment on PRs.

Now that we have set up our Codecov accounts, let’s upload coverage reports.

Add the Codecov token

For more information on tokens, seethe documentation.

ClickConfigure on our demo repo, selectUsing Codecov's CLI. We will only doStep 1 since we are using GitLabCI for this demo.

Toadd repository token as a secret to your CI Provider, from the demo repository's page on GitLab, go toSettings -> CI/CD. UnderVariables,Add Variable to add your token as shown below.

SelectAdd variable to save.

Create GitLabCI pipeline

We need to create a configuration file for GitLabCI. The CI workflow below will checkout the code, install requirements, run tests, and upload the coverage reports to Codecov.

Add the following code to a new.gitlab-ci.yml file at the root of your project

api:  image: python:latest  script:    - pip install -r api/requirements.txt    - pytest --cov api/    - curl -Os https://cli.codecov.io/latest/linux/codecov    - chmod +x codecov    - ./codecov upload-process -t $CODECOV_TOKEN

Commit the changes and run the CI workflow

Let’s commit our code and open a pull request. Run

git add .git commit -m 'step2: upload coverage reports to Codecov'git push origin step2

Next, go to the demo repository on GitLab and open a merge request, which will run our GitLabCI pipeline for the first time.

When opening merge requests, be sure to select your own repository as the target branch, orset your project's default target branch

🚧

Token not found

You should expect to see
['info'] -> Token found by environment variables
in the logs in your CI. If you are not seeing this, make sure that you have added the variable and that the CI pipeline has access to the variable.

You will see status checks on the MR from the CI. You can click on them to see the progress of the CI/CD. Once complete, you will receive status checks and a comment from Codecov.

codecov/patch andcodecov/project status checks

One of Codecov’s core uses is getting code coverage information directly in a developer’s workflow. The status checks shown above are part of that.

• Thepatch check is used for code changed in a PR, this is enabled by default.
• Theproject check is used to maintain a coverage percentage across an entire codebase, we will add this check in the next step.

A more mature repository may have a strictproject percentage, while a project new to code coverage may only expect new code to be well-tested (patch coverage). We will be setting some of these values in this section, but you can read more about status checkshere.

If you go to the project on Codecov, you will notice that the dashboard is blank. This is because no coverage information has been uploaded onto the main branch. We can fix this by merging the pull request!

Merge the MR on GitLab and wait for the CI/CD to complete.

When opening merge requests, be sure to select your own repository as the target branch, orset your project's default target branch
