Virtuous' Unit Test Suite
This configuration uses Jest for running the tests. It is only an extension of the default Jest configuration.
Installation
NPM
npm install --save-dev @virtuous/unit-tests
Yarn
yarn add --dev @virtuous/unit-tests
Usage
All test files should follow the naming convention of *(spec|test).js
. But that is not mandatory.
You can also put your test files into one or multiple __tests__
folder(s).
NOTE: It is considered a best practice to create __tests__
folder(s) AND have the file endings like *.spec.js
or *.test.js
!
Test Setup
You have two options of how to create a configuration for Jest:
- You can create your own configuration following the Jest Documentation
- You can use Virtuous' pre-defined configuration and extend it as you wish.
NOTE: Using and extending the Virtuous configuration is the preferred way!
1. Using Virtuous' configuration
Create a file called jest.config.js
in the root of your project.
Add the following line to it:
module.exports = require('@virtuous/unit-tests/jest.config');
2. Extending Virtuous' configuration
Create a file called jest.config.js
in the root of your project.
Add the following line in the beginning of the file:
const defaultConfig = require('@virtuous/unit-tests/jest.config');
This will load the default configuration. Now you can extend it by spreading the defaultConfig
into a newly created configuration object:
module.exports = Object.assign({}, defaultConfig, {}
[Your config goes here],
});
Example Configuration
Here is an example showing how to extend the default configuration:
const defaultConfig = require('@virtuous/unit-tests/jest.config');
module.exports = Object.assign({}, defaultConfig, {
moduleNameMapper: {
'^Components(.*)$': '<rootDir>/components',
'^Styles(.*)$': '<rootDir>/styles',
},
});
