Codecov

Codecov is a code coverage reporting platform that that monitors how much of your code has been tested and validated. Codecov analytics can be used to drive visibility into your microservice architecture and understand coverage trends over time.

Integrating Cortex with Codecov allows you to:

• View code coverage details for entities directly in Cortex

• Create Scorecards that track progress and drive alignment on projects involving your Codecov code coverage metrics

How to configure Codecov with Cortex

Prerequisites

Before getting started:

• Create a Codecov access token.

Configure the integration in Cortex

1. In Cortex, navigate to the Codecov settings page:

   1. In Cortex, click your avatar in the lower left corner, then click Settings.

   2. Under "Integrations," click Codecov.

2. Click Add configuration.

3. Configure the Codecov integration form:

   • API token: Enter your Codecov access token.

   • Host: If you're using a custom Codecov instance, enter your host URL.

     • Make sure to enter the URL without the API path (e.g., https://codecov.getcortexapp.com).

4. Click Save.

How to connect Cortex entities to Codecov

Auto discovery of Codecov projects

Cortex will use the GitHub, GitLab, Bitbucket, or Azure DevOps repository as the "best guess" for the corresponding Codecov project, since Codecov projects are connected to repositories. For example, if the GitHub repo associated with your Codecov instance is my-org/repo, then the entities in Cortex should also be associated with my-org/repo.

You can find the repository for a given entity in its YAML, defined in a block like the one below:

x-cortex-git:
  github:
    repository: cortexapps/sample-repo

If the Codecov project you want to associate isn't the same as the repository, you can override this in the Cortex entity descriptor.

While Cortex uses the entity tag for discovery with many integrations, the repository is used for Codecov projects.

Editing the entity descriptor

x-cortex-static-analysis:
  codecov:
    owner: org-name
    repo: my-project
    provider: AZURE_DEVOPS | BITBUCKET | BITBUCKET_SERVER | GITHUB | GITHUB_ENTERPRISE | GITLAB | GITLAB_ENTERPRISE
    flag: flag

Field	Description	Required
owner	Name of the Git organization	✓
repo	Git repository (without the organization)	✓
provider	One of the Git providers in the sample YAML	✓
flag	Pulls from isolated and categorized coverage reports

The value for repo should be the full repository because Codecov maps projects by repo.

Flags

Codecov's flags are used to categorize coverage reports for various features and tests in a given project. Flags allow you to set different statistics for different areas of your code base. For example, if you have a monorepo with multiple unique projects, you can use Codecov flags to evaluate each project with different test coverage metrics.

To pull flags into Cortex, define the flag line in the entity descriptor block.

If you choose to configure with flags, discovery will be disabled; you would need to define the owner, repo, and provider lines.

Expected results

Entity pages

With the Codecov integration, you can find code coverage details on an entity's details page as long as that entity is associated with a repo linked to your Codecov instance.

Click Code & security in the entity's sidebar to see the code coverage for that entity.

Scorecards and CQL

With the Codecov integration, you can create Scorecard rules and write CQL queries based on Codecov code coverage metrics.

See more examples in the CQL Explorer in Cortex.

Code coverage

Code coverage for an entity's Git repository (out of 100)

Definition: codecov.codeCoverage()

Example

For a Scorecard focused on development maturity, you can set a rule to make sure code coverage for a given entity is at least 95%:

codecov.codeCoverage() >= 95

Set a threshold that is both challenging and realistic so there's an incentive for developers to improve.

Setting up a rule based on code coverage can serve as a secondary check to confirm an entity is synced with Codecov and reporting frequently.
