About • Organisation • Testing & Status • Licensing

This repository holds business rules to determine whether a person is deemed fit-for-travel into a country-of-arrival (CoA) based on their vaccination, test, and recovery status, as encoded using the Digital COVID Certificate. The status of the business rules here is unofficial: the actual rules will be available from the DCGC Gateway. Its main purpose is to help with developing interchangeable business rules.

This repository performs automatic validation and testing on all the rules, and their tests, contributed to it. This validation and testing runs on every Pull Request, but can also be run locally from the commandline, as follows:

$ (cd tooling ; sh build.sh)

The “CertLogic Validation” GitHub Action performs this exact same command. It requires a UNIX-like shell, Git, curl, and a recent Node.js (with the NPM package manager) to be installed.

After having run this command once, you can just run the validation/testing as follows:

$ (cd tooling ; npm test)

Validation encompasses the following:

• The JSON file of every rule is validated against this JSON Schema.
• The Logic field of every rule is validated as a CertLogic expression, which is a format/language that's specified here.
• The specified AffectedFields field is checked against the fields of the DCC payload accessed from the Logic field.
• ...more validations and checks to follow

Testing means that all rules' tests are executed using the JS-implementation of CertLogic. JSON files containing tests must adhere to this JSON Schema.

All rules are also executed against every DCC found in the DCC test data repo. The results are exposed as an artifact (called rules-on-testData.json) of the "Validation and Testing of Rule Sets" GitHub Action.

This repository contains the following:

• GitHub Actions configuration
• tests: testing material called by the “Business Rule Validation” GitHub Action
• tooling: testing material called by the “CertLogic Validation” GitHub Action
• EU: EU template/recommendation rules
• DE, FI, NL, etc.: actual rules for EU Member States

• If you found any problems, please create an Issue.
• Current status: Work-In-Progress + see above.
