GitHub Actions

Prerequisites

Add the CIFUZZ_DOWNLOAD_TOKEN from downloads.code-intelligence.com as a secret to the GitHub project via "Settings" -> "Secrets and variables" -> "Actions" to access it in the actions.

For more details on what you can do with CI Fuzz and its outputs in your pipeline, check the general CI/CD-Setup page.

Example workflow

The following GitHub Actions workflow shows an example of how you can run CI Fuzz in GitHub Actions.

• If you want to commit your Findings to the repository, uncomment the contents: write permission and the Commit Findings and corpus to repository step.
• If code scanning isn't available or not needed in your project, comment the security-events: write permission and the Upload code-scanning report step.

name: Fuzzing with CI Fuzz

# Runs all Fuzz Tests in this repository with CI Fuzz.

# You need to set CIFUZZ_DOWNLOAD_TOKEN as a repository secret. Get the token
# from https://downloads.code-intelligence.com/.

# Run workflow each time code is pushed to default branch of the repository,
# for every pull request to the default branch and on a schedule. Allow to
# run this workflow manually.
# The scheduled workflow runs every day at 03:50 UTC.
