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.
In this guide, you'll learn how to set up and use the Codecov integration to drive insights into code coverage.
Setup and configuration
Getting started
In order to connect Cortex to your Codecov instance, you’ll need to create a Codecov access token.
Configuration
Once you've created an access token, add it on the Codecov Settings page in the API token field.
If you do not see the settings page you're looking for, you may not have permission to access that page. Please contact your admin for assistance.
You can also add an optional Host at this step if you're using a custom Codecov instance. Make sure to enter the URL without the API path (e.g. https://codecov.getcortexapp.com
).
If you’ve set everything up correctly, you’ll see the option to Remove Integration in settings.
You can also use the Test configuration button to confirm that the configuration was successful. If your configuration is valid, you’ll see a banner that says “Configuration is valid. If you see issues, please see documentation or reach out to Cortex support.”
Registration
Discovery
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 will use the entity tag for discovery with many integrations, the repository is used for Codecov projects.
Entity descriptor
If you need to override automatic discovery, you can define the following block in your Cortex 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.
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.
From the Integrations tab in the sidebar, you can open the Codecov page to find 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()
Details
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.
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 a bunch of unique projects, you can use Codecov flags to evaluate each project with different test coverage metrics.
You can pull flags into Cortex by defining the flag
line in the entity descriptor block above.
If you choose to configure with flags, discovery will be disabled, so you'll also have to define the owner
, repo
, and provider
lines.
