我正在尝试在Jest中模拟AWS SES,但继续收到此超时错误:
Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.Error:
我已经删除了不相关的代码,并验证了它们可以正常工作。这是使用SES的代码:
import SES from 'aws-sdk/clients/ses';
try {
/** Initialize SES Class */
const ses = new SES({ apiVersion: '2010-12-01' });
await ses.sendTemplatedEmail(sesEmailParams).promise();
} catch(err) {
return next(internalErrorMessage);
}
这里是使用SES的测试:
import AWS from 'aws-sdk';
test('Should error when ses.sendTemplatedEmail.promise() fails', async (done) => {
const fakeSesPromise = {
promise: jest
.fn()
.mockImplementationOnce(() => Promise.reject(new Error('This is an SES error'))),
};
const fakeSes = {
sendTemplatedEmail: () => {
return fakeSesPromise;
},
};
AWS.SES = jest.fn(() => fakeSes);
await user.forgotPassword(mockRequest, mockResponse, mockNext);
expect(fakeSesPromise).toHaveBeenCalledTimes(1);
expect(mockNext).toHaveBeenCalledWith(internalErrorMessage);
done();
});
我已经尝试了其他建议的方法,但均以相同的结果结束。我假设它与aws-sdk
如何使用.promise()
函数有关。
任何帮助将不胜感激!
aws-sdk/clients/ses
模块,SES
类及其方法的单元测试解决方案。例如
user.js
:
import SES from 'aws-sdk/clients/ses';
const internalErrorMessage = 'internalErrorMessage';
export const user = {
async forgotPassword(req, res, next) {
const sesEmailParams = {
Source: 'Sender Name <[email protected]>',
Destination: {
ToAddresses: [],
},
Template: 'tpl',
TemplateData: 'data',
};
try {
const ses = new SES({ apiVersion: '2010-12-01' });
await ses.sendTemplatedEmail(sesEmailParams).promise();
} catch (err) {
return next(internalErrorMessage);
}
},
};
user.test.js
:
import MockSES from 'aws-sdk/clients/ses'; import { user } from './user'; jest.mock('aws-sdk/clients/ses', () => { const mSES = { sendTemplatedEmail: jest.fn().mockReturnThis(), promise: jest.fn(), }; return jest.fn(() => mSES); }); describe('61491519', () => { test('Should error when ses.sendTemplatedEmail.promise() fails', async () => { const mSes = new MockSES(); const mError = new Error('This is an SES error'); mSes.sendTemplatedEmail().promise.mockRejectedValueOnce(mError); const mockRequest = {}; const mockResponse = {}; const mockNext = jest.fn(); await user.forgotPassword(mockRequest, mockResponse, mockNext); expect(MockSES).toBeCalledWith({ apiVersion: '2010-12-01' }); expect(mSes.sendTemplatedEmail).toBeCalledWith({ Source: 'Sender Name <[email protected]>', Destination: { ToAddresses: [], }, Template: 'tpl', TemplateData: 'data', }); expect(mSes.sendTemplatedEmail().promise).toBeCalledTimes(1); expect(mockNext).toHaveBeenCalledWith('internalErrorMessage'); }); });
