{this.state.counter}
;\n }\n}\n```\n\nWe can write a test file that grabs the source from the global `sources` object and simulates messages:\n\n```js\n// @flow\nimport React from 'react';\nimport { mount } from 'enzyme';\n\nimport Component from './Component';\nimport { sources } from 'eventsourcemock';\n\nconst messageEvent = new MessageEvent('foo', {\n data: '1',\n});\n\ndescribe('update counter on SSE', () => {\n let wrapper;\n beforeAll(() => {\n wrapper = mount();\n sources['http://example.com/events'].emitOpen();\n });\n\n it('should initialise counter to 0', () => {\n expect(wrapper.state('counter')).toBe(0);\n });\n\n it('should display \"0\"', () => {\n expect(wrapper.text()).toBe('0');\n });\n\n it('should update the counter to 1', () => {\n sources['http://example.com/events'].emit(\n messageEvent.type,\n messageEvent\n );\n expect(wrapper.state('counter')).toBe(1);\n });\n\n it('should close the EventSource on unmount', () => {\n wrapper.unmount();\n expect(sources['http://example.com/events'].readyState).toBe(2);\n });\n});\n\n```\n\n## API\n### `sources: { [key: string]: EventSource }`\n`sources` holds the `EventSource` instances created.\n\n```js\nimport { sources } from 'eventsourcemock';\n```\n\n### `EventSource`\n`EventSource` mocks `window.EventSource`, providing methods to simulate messages and errors from the network.\n```js\nimport EventSource from 'eventsourcemock';\n```\n#### Constructor\n```js\nEventSource(\n url: string,\n options?: {\n withCredentials: boolean\n }\n)\n```\n\n#### Properties\n##### `__emitter`\nA reference to the [node `EventEmitter`](https://nodejs.org/api/events.html#events_class_eventemitter) instance used internally.\n\n##### `onopen`\nSee [eventSource.onopen](https://developer.mozilla.org/en-US/docs/Web/API/EventSource/onopen).\n\n##### `onmessage`\nSee [eventSource.onmessage](https://developer.mozilla.org/en-US/docs/Web/API/EventSource/onmessage).\n\n##### `onerror`\nSee [eventSource.onerror](https://developer.mozilla.org/en-US/docs/Web/API/EventSource/onerror).\n\n##### `readyState`\nSee [eventSource.readyState](https://developer.mozilla.org/en-US/docs/Web/API/EventSource/readyState).\n\n##### `url`\nSee [eventSource.url](https://developer.mozilla.org/en-US/docs/Web/API/EventSource/url).\n\n##### `withCredentials`\nSee [eventSource.withCredentials](https://developer.mozilla.org/en-US/docs/Web/API/EventSource/withCredentials).\n\n\n#### Methods\n##### `emit(eventName: string, messageEvent?: MessageEvent)`\nCalls each of the listeners registered for the event named `eventName`, providing `messageEvent` as argument.\n\n*Example*\n```js\nconst messageEvent = new MessageEvent('type', {\n data: 'message event data'\n});\nsource.emit(messageEvent.type, messageEvent);\n```\n\n#### `emitOpen()`\nSimulates the opening of a connection. It sets the ready state to open and invokes the callback.\n\n##### `emitMessage(message: any)`\nSimulates dispatching of a message, it invokes the `onmessage` callback.\n\n#### `emitError(error: Error)`\nSimulates dispatching an error event on the `EventSource` instance. Causes `onerror` to be called.\n\n*Example (jest)*\n```js\nconst onErrorSpy = jest.fn();\nconst error = new Error('Something went wrong.');\neventSource.onerror = onErrorSpy;\neventSource.emitError(error);\nexpect(onErrorSpy).toHaveBeenCalledWith(error);\n```\n\n##### `addEventListener(eventName: string, listener: Function)`\nSee [EventTarget.addEventListener](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener).\n\n##### `removeEventListener(eventName: string, listener: Function)`\nSee [EventTarget.removeEventListener](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/removeEventListener)\n\n##### `close()`\nSee [EventSource.close](https://developer.mozilla.org/en-US/docs/Web/API/EventSource/close).","users":{}}
