@procore/hammer-test-jest

The jest implementation of the test commands.

Quick Start

Run test commands from the hammer command. If this package is not already installed, or is out-of-date, you will be prompted to install/upgrade.

Alternatively, you can install it directly:

yarn add -D @procore/hammer-test-jest

Configuration

Custom configuration is done using the hammer configuration file. The customization key is jestOverride, and the configuration that should be returned should be compatible with the jest format.

export default {
    testJest(originalConfig) {
        const customizedConfig =
        // ... mutations, transformations, etc.
        return customizedConfig;
    }
}

NOTE: The default configuration should handle nearly all packages. If you find that you are doing a lot of customization, or the same change in multiple projects, consider reviewing your configuration with the UI Foundations team.
