TestingLogger

@vendure/testing Source

The TestingLogger can be used in unit tests or e2e tests to make assertions on whether the various Logger methods have been called, and which arguments.

Here's some examples of how to use it in e2e tests and unit tests. In both cases we are using the Jest testing framework, but the TestingLogger should work with other similar frameworks (e.g. replacing jest.fn() with jasmine.createSpy()).

Example

// e2e test exampleimport { createTestEnvironment, TestingLogger } from '@vendure/testing';const testingLogger = new TestingLogger(() => jest.fn());const { server, adminClient, shopClient } = createTestEnvironment({  ...testConfig,  logger: testingLogger,});// e2e testing setup omittedit('should log an error', async () => {  // The `errorSpy` property exposes the Jest mock function  testingLogger.errorSpy.mockClear();  await doSomethingThatErrors();  expect(testingLogger.errorSpy).toHaveBeenCalled();});
