Hapi Lab - 我如何在实验室实验之间共享状态

Question

所以我编了用户域我已经完成了，我认为这是一个很好的套房测试它是这样的：

var Code = require('code');
var Lab = require('lab');
var lab = exports.lab = Lab.script();
var server = require('../../');
var Jwt = require('jsonwebtoken');
var Nconf = require('nconf');
var apiConfig =  Nconf.get('api');

lab.experiment('Users', function () {

    var userId, payload, decoded, token;

    lab.test('create joi required', function (done) {

        var options = {
            method: 'POST',
            url: '/api/users',
            payload: {
                lastname: 'Bedini',
                username: 'whisher',
                email: 'me@ilwebdifabio.it',
                password: 'mysecret'
            }
        };

        server.inject(options, function(response) {
            var result = response.result;
            Code.expect(response.statusCode).to.equal(422);
            Code.expect(result.message).to.equal('child "firstname" fails because ["firstname" is required]');
            done();
        });

    });

    lab.test('create', function (done) {

        var options = {
            method: 'POST',
            url: '/api/users',

        };

        server.inject(options, function(response) {

            token = response.result.token;
            payload = options.payload;
            Code.expect(response.statusCode).to.equal(201);
            try {
                decoded = Jwt.verify(token, apiConfig.secret);
            }
            catch(err) {
            }
            console.log(decoded.scope);
            Code.expect(decoded.username).to.equal(payload.username);
            Code.expect(decoded.scope).to.be.an.array();
            userId = decoded.jti;
            done();
        });

    });

    });

    lab.test('update', function (done) {

        var updatevalue = Math.random().toString(36).slice(2);

    lab.test('destroy not owner', function (done) {

            done();
        });

    });

});

现在我也创建了产品域是一些路由需要访问令牌。

如何使用 'globals'

测试产品域

var userId, payload, decoded, token;

或者这种情况下怎么转？

@Matt Harrison 回答后

var getToken = function(){
    var user = {id:1,username:'abcdefghijklmnopqrstuvwxyz'};
    var token = JwtUtil.getUserToken(user).token;
    return token;
}
lab.experiment('Product', function () {



    lab.test('create', function (done) {
        var token = getToken();
        console.log(token);
        var options = {
            method: 'POST',
             headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/products',
            payload: {
                title: 'myproduct'
            }
        };

        server.inject(options, function(response) {
            var result = response.result;
            console.log(result);
            Code.expect(response.statusCode).to.equal(200);
           // Code.expect(result.message).to.equal('child "firstname" fails because ["firstname" is required]');
            done();
        });

    });


});

它工作正常我还有一个问题与

CONSTRAINT products_ibfk_1 FOREIGN KEY (userId) REFERENCES users (id) ON UPDATE CASCADE) stack: Error: ER_NO_REFERENCED_ROW

不确定我是否正确理解了你的问题，但我认为你在问：

How do I have shared state between lab experiments?

简单的答案是将 var userId, payload, decoded, token; 移动到上层 "global" 范围，这样它们就可以随处访问。

不过我的建议是不要这样做。您的测试用例应该彼此独立。您应该能够在不影响其他测试用例的情况下添加测试、重新排序和删除它们。否则，您就是在为自己制造一场维护噩梦。

如果您在多个测试用例中需要一个资源，只需为每个测试创建一个新资源：

lab.test('test the thing', function (done) {

    var token = getToken();
    expect(token).to.equal(...);
});

lab.test('test the other thing', function (done) {

    var token = getToken();
    expect(token).to.equal(...);
});

如果您需要更改资源然后测试某些内容，那就是单个测试用例：

lab.test('change something and then test it', function (done) {

    var token = getToken();
    token.prop = 'value';
    expect(token.prop).to.equal('value');
});
