我为_getuser（）写了一个单元测试，但我没有看到控制台. log打印存根结果。测试覆盖显示行'let user=结果.user；控制台.log（'User'JSON.stringify（结果））；'未覆盖。为什么存根结果不会在LogInCommand类的getUser（）函数的控制台日志中打印。我看到单元测试中的结果显示未定义。
// userApi.js
'use strict';
const config = require('../../config/config');
const api = require('./apiService');
class UserApi {
constructor() {
}
getUser(userId) {
return api.get({
url: config.url,
qs: {
includeInactive: true,
id: userId,
startIndex: 0,
maxResults: 1
},
headers: {
Accept: 'application/json;',
'Connection': 'Keep-Alive'
}
});
}
}
module.exports = UserApi;
// LoginCommand.js
'use restrict';
const userApi = require('../../api/userApi');
class LogInCommand {
constructor() {
}
async _getUser(userId) {
let result = await new userApi().getUser(userId);
let user = result.user;
console.log('User'+JSON.stringify(result));
return user;
}
}
module.exports = LogInCommand;
//LoginCommand.test.js
describe('Test LogInCommand Class',function(){
it.only('_getUser function should return user', async ()=> {
let apiData= {
user:'abc'
};
let logincmd = proxyquire('../LogInCommand.js', {
userApi : { getUser : Promise.resolve(apiData) },'@noCallThru':true});
let obj= new logincmd();
let result= await obj._getUser(client);
});
});
在您当前的设置中，proxyquire配置不正确。Proxyquire将需求调用中传递的字符串值映射到所需的模拟/存根值。请尝试以下操作：
let logincmd = proxyquire('../LogInCommand.js', {
'../../api/userApi' : { getUser : Promise.resolve(apiData) },
'@noCallThru':true
});
下面的代码对我有用//userApi. js
'use strict';
const config = require('../../config/config');
const api = require('./apiService');
class UserApi {
constructor() {
}
getUser(userId) {
return api.get({
url: config.url,
qs: {
includeInactive: true,
id: userId,
startIndex: 0,
maxResults: 1
},
headers: {
Accept: 'application/json;',
'Connection': 'Keep-Alive'
}
});
}
}
module.exports = UserApi;
// LoginCommand.js
'use restrict';
const userApi = require('../../api/userApi');
class LogInCommand {
constructor() {
}
async _getUser(userId) {
let result = await new userApi().getUser(userId);
let user = result.user;
console.log('User'+JSON.stringify(result));
return user;
}
}
module.exports = LogInCommand;
//LoginCommand.test.js
describe('Test LogInCommand Class',function(){
it.only('_getUser function should return user', async ()=> {
class userApiStub{
constructor(){}
getUser() {
return Promise.resolve({
user:4
});
}
}
let logincmd = proxyquire('../LogInCommand.js', {
'../../api/userApi' :userApiStub },'@noCallThru':true});
let obj= new logincmd();
let result= await obj._getUser(client);
});
});
