Contributing

Thank you for taking your time to contribute to the SAP Cloud SDK!

Project Structure

This project containes multiple packages, that are managed using lerna and yarn workspaces. Productive packages are located in the packages directory, test packages are located in the test-packages directory. All dependencies that are used in more than one of the packages are hoisted into the root project. Dependencies, that occur only once and binaries will be placed in the node_modules of that specific package. Some of the packages are interdependent, therefore yarn install won't work from within those packages. Run yarn install in the root directory instead.

Testing

In order to run all tests, execute:

$ yarn test

This will run unit tests for all our packages as well as integration tests and type tests. You can run those individually as described in the following.

Unit Tests

Unit tests shall test specific modules of a package, units that are tested for behavior. You can run all unit tests by executing:

$ yarn test:unit

To run unit tests for a specific package add the workspace name to the command. For the core package this would be:

$ yarn @sap-cloud-sdk/core run test

Integration Tests

Integration tests shall test how modules behave in combination. The integration tests are located in test-packages/integration-tests.

To run the integration tests, execute:

$ yarn test:integration

Type Tests

As this project is written in TypeScript, it shall be consumable by other TypeScript projects. We use dtslint to test that our resulting API meets our expectations. The type tests are located at test-packages/type-tests.

To run the integration tests, execute:

$ yarn test:type

Test Services

To simplify testing we are using tests services. The specifications for those can be found in test-resources. They are used from different tests on different levels. The service specifications are directly used by the unit tests of the generator. From the specifications, we generate two OData clients. First, we generate type script sources, that are generated into the test-utils of the core, where we replace all references to the @sap-cloud-sdk/core with a reference to the local sources. The resulting test service is used in the unit tests of the core package. Second, we generate a transpiled version of a non-modified OData client based on the specifications, that is located at test-packages/test-services. This is used in the integration tests and type tests.

If you need to extend the existing services, run the following to regenerate the OData clients.

$ yarn generate:test-services

Linting

To fix all linting issues, run:

$ yarn lint:fix
