mockire

    1.1.4 • Public • Published

    This library allows developers to stub and clear the require built-in method.

    The Mockire interceptor is initialized as soon as the module is required.

    Use with caution.

    Methods

    • match(pattern, value): matches the module path against a regular expression.
    • exact(input, value): expects the provided path to be exactly as required.
    • clearStubs(): clears all stubs.
    • reset(): removes the monkey patch.
    • init(): initializes the interceptor.
    • clearRequireCache(): clears all modules stored in the require cache. Modules will be loaded again next time require is invoked.

    Use cases:

    Clearing cache before tests start

    const { clearRequireCache } = require('mockire');
    let server;
    describe('Unit tests', () => {
        before((done) => {
            clearRequireCache();
            server = require('./MyCustomServer');
        })
    } 
    

    Loads fake dependencies

    const { match } = require('mockire');
    match('MyProjectDirectory/config/env/*', { port: 8000, db: { host: 'localhost', port: '27017' } });
    const server = require('./MyCustomServer');
    
    describe('Unit tests', () => {
        before((done) => {
            server.start()
        })
    } 
    

    Creates virtual dependency

    const { exact, clearStubs } = require('mockire');
    if (!fs.existsSync('./path/customLib)) {
        exact('./path/customLib', { something });
    }
    const lib = require('./path/customLib');
    await lib.foo();
    clearStubs();
