Running Tests

Prerequisites

Before running tests, you must build the release binaries:

cargo build --release

Running Integration Tests

Use the following command to run integration tests:

yarn test:integration <jest cli options>

For example:

• Run all tests: yarn test:integration
• Run a specific test file: yarn test:integration path/to/test.ts
• Run tests matching a pattern: yarn test:integration -t "pattern"
• Run in watch mode: yarn test:integration --watch

Reading spawn logs

You can access the logs of any Yarn command spawned within a test by adding the JEST_LOG_SPAWNS=1 environment variable.

Creating temporary projects

You can setup temporary projects by:

1. Creating a new temporary folder
2. Adding an empty package.json file
3. Running yarn switch link path/to/target/Release/yarn-bin inside this temporary folder
4. Subsequent yarn commands should then use the local binary
