我正在尝试使用Jest用Flux代码测试React。我对单元测试相当陌生。
我觉得我在嘲笑我的依赖方面做得不对(说实话,嘲笑的事情有点让我困惑)。
以下是我遇到的问题:
//LoginStore-test.js
jest.dontMock('../../constants/LoginConstants');
jest.dontMock('jsonwebtoken');
jest.dontMock('underscore');
jest.dontMock('../LoginStore');
describe("login Store", function(){
var LoginConstants = require('../../constants/LoginConstants');
var AppDispatcher;
var LoginStore;
var callback;
var jwt = require('jsonwebtoken');
var _user = {
email: 'test@test.com'
};
//mock actions
var actionLogin = {
actionType: LoginConstants.LOGIN_USER,
'jwt': jwt.sign(_user, 'shhh', { expiresInMinutes: 60*5 })
};
beforeEach(function(){
AppDispatcher = require('../../dispatchers/AppDispatcher');
LoginStore = require('../LoginStore');
callback = AppDispatcher.register.mock.calls[0][0];
});
...
it('should save the user', function(){
callback(actionLogin);
var user = LoginStore.getUser();
expect(user).toEqual(_user);
});
});
});
LoginStore.js文件:
var AppDispatcher = require('../dispatchers/AppDispatcher');
var BaseStore = require('./BaseStore');
var LoginConstants = require('../constants/LoginConstants.js');
var _ = require('underscore');
var jwt = require('jsonwebtoken');
//initiate some variables
var _user;
var _jwt;
var LoginStore = _.extend({}, BaseStore, {
getUser: function(){
return _user;
}
});
AppDispatcher.register(function(action){
switch(action.actionType){
case LoginConstants.LOGIN_USER:
//set the user
_user = jwt.decode(action.jwt);
//save the token
_jwt = action.jwt;
break;
//do nothing with the default
default:
return true;
}
LoginStore.emitChange();
return true;
});
module.exports = LoginStore;
jsonwebtoken
功能似乎根本不起作用。如果我记录actionLogin.jwt
,它只返回undefined
。知道我在这里做错了什么吗?
干杯
经过一番搜索,并试图找出不同的问题,我找到了答案。只需添加
"jest": {"modulePathIgnorePatterns": ["/node_modules/"]}
到您的package.json文件
