我正在尝试使用注册功能测试 Hapi.js 插件：
exports.register = function(server, options, next) {
server.route({
method: 'POST',
path: '/register',
config: {
payload: {
allow: 'application/json'
},
validate: {
/* deleted for brevity */
}
},
handler: function(request, reply) {
if (!server.app.mongoose) {
server.log('error', 'Failed to find an active MongoDB connection.');
return reply(Boom.badImplementation());
}
var response = reply().hold();
var mongoose = server.app.mongoose;
var User = mongoose.model('User');
var password = request.payload.password;
return new Promise(function(resolve, reject) {
bcrypt.genSalt(10, function(err, salt) {
if (err) {
server.log('error', 'Failed to generate bcrypt salt: ' + err);
return reject();
}
bcrypt.hash(password, salt, function(err, hash) {
/* deleted for brevity */
user.save(function(err, savedUser) {
if (err) {
server.log('error', 'Failed to save user to the database: ' + err);
return reject(Boom.conflict());
}
server.log('debug', 'Registered new user with e-mail validation code: ' + validationCode);
resolve({});
});
});
});
}).then(function(data) {
response.statusCode = 201;
response.source = data;
response.send();
return response;
}, function(err) {
if (!err)
err = Boom.badImplementation();
response.statusCode = err.output.statusCode;
response.source = err.output.payload;
response.send();
return response;
});
}
});
next();
};
我的测试文件在这里：
const Lab = require('lab');
const expect = require('code').expect;
const server = require('../');
const lab = exports.lab = Lab.script();
const mongoose = require('../plugins/mongo.js').mongoose;
lab.experiment('Registration', function() {
lab.before(function(done) {
mongoose.connection.collections['users'].drop(function(err, resp) {
if (err) {
console.error(err);
} else {
console.log(resp);
}
});
var User = mongoose.model('User');
/* deleted for brevity */
user.save(function(err, savedUser) {
if (err) {
server.log('error', 'Failed to save user to the database: ' + err);
done(err);
}
done();
});
});
lab.test('/register endpoint with empty payload', function(done) {
server.inject({
method: 'POST',
url: '/register',
payload: {}
}, function(response) {
expect(response.statusCode).to.be.equal(400);
expect(response.result.message).to.match(/^child "\w+" fails because \["\w+" is required\]$/);
done();
});
});
lab.test('/register endpoint with invalid email', function(done) {
server.inject({
method: 'POST',
url: '/register',
payload: {
...
}
}, function(response) {
expect(response.statusCode).to.be.equal(400);
expect(response.result.message).to.be.equal('child "email" fails because ["email" must be a valid email]');
done();
});
});
lab.test('/register endpoint with short password', function(done) {
server.inject({
method: 'POST',
url: '/register',
payload: {
...
}
}, function(response) {
expect(response.statusCode).to.equal(400);
expect(response.result.message).to.startWith('child "password" fails because ["password" length must be at least');
done();
});
});
lab.test('/register endpoint with invalid password', function(done) {
server.inject({
method: 'POST',
url: '/register',
payload: {
...
}
}, function(response) {
expect(response.statusCode).to.equal(400);
expect(response.result.message).to.startWith('child "password" fails because');
done();
});
});
lab.test('/register endpoint with existing username', function(done) {
server.inject({
method: 'POST',
url: '/register',
payload: {
...
}
}, function(response) {
expect(response.statusCode).to.equal(409);
done();
});
});
lab.test('/register endpoint with valid payload', function(done) {
server.inject({
method: 'POST',
url: '/register',
payload: {
...
}
}, function(response) {
expect(response.statusCode).to.equal(201);
done();
});
});
});
一切都很好，直到我添加了“使用现有用户名的 /register 端点”。
现在，lab 命令的后续调用成功退出，然后测试 5 和 6 失败（它像这样继续下去，一次成功，然后一次失败）。基本上，看起来结果状态代码在成功测试启动后被交换。
看起来像一个同步问题，但我找不到原因。有任何想法吗？
