Hapi实验室-如何在实验室实验之间共享状态？

Question

因此，我创建了用户域，我做了--我认为一个很好的套件测试--如下所示：

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',
            payload: {
                firstname: 'Fabio',
                lastname: 'Bedini',
                username: 'whisher',
                email: 'me@ilwebdifabio.it',
                password: 'mysecret'
            }
        };

        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('create sequelize unique', function (done) {

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

        server.inject(options, function(response) {
            var result = response.result;
            Code.expect(result.message).to.equal('username must be unique');
            Code.expect(response.statusCode).to.equal(422);
            done();
        });

    });

    lab.test('update at least one required', function (done) {

        var options = {
            method: 'PUT',
            headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/users/'+userId
        };

        server.inject(options, function(response) {
            var result = response.result;
            Code.expect(response.statusCode).to.equal(422);
            done();
        });

    });

    lab.test('update no password', function (done) {

        var options = {
            method: 'PUT',
            headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/users/'+userId,
            payload: {
                password: 'mysecret_update'
            }
        };

        server.inject(options, function(response) {
            var result = response.result;
            Code.expect(response.statusCode).to.equal(422);
            done();
        });

    });

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

        var options = {
            method: 'PUT',
            headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/users/'+userId +1,
            payload: {
                firstname: 'Fabio_update'
            }
        };

        server.inject(options, function(response) {
            Code.expect(response.statusCode).to.equal(403);
            done();
        });

    });

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

        var updatevalue = Math.random().toString(36).slice(2);
        var options = {
            method: 'PUT',
            headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/users/'+userId,

                email: 'me_'+updatevalue+'@ilwebdifabio.it'
            }
        };

        server.inject(options, function(response) {
            var result = response.result;
            Code.expect(response.statusCode).to.equal(200);
            Code.expect(result).to.equal(1);
            done();
        });

    });

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

        var options = {
            method: 'GET',
            headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/users/'+userId +1,
        };

        server.inject(options, function(response) {
            Code.expect(response.statusCode).to.equal(403);
            done();
        });

    });

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

        var options = {
            method: 'GET',
            headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/users/'+userId
        };

        server.inject(options, function(response) {
            var result = response.result;
            Code.expect(response.statusCode).to.equal(200);
            Code.expect(result).to.be.instanceof(Object);
            Code.expect(Object.keys(result)).to.have.length(8);
            done();
        });

    });

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

        var options = {
            method: 'DELETE',
            headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/users/'+userId+1
        };

        server.inject(options, function(response) {
            Code.expect(response.statusCode).to.equal(403);

    });

            method: 'DELETE',
            headers:{'Authorization' : 'Bearer ' + token},
            url: '/api/users/'+userId

        server.inject(options, function(response) {
            var result = response.result;
            Code.expect(response.statusCode).to.equal(200);
            Code.expect(result).to.equal(1);
            done();
        });

    });

});

现在，我也组成了产品域，并且有一些路由需要访问令牌。

如何使用“globals”测试产品域？

var userId，有效载荷，解码，令牌；

或者这个案子是怎么回事？

@Matt Harrison回答

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();
        });

    });


});

我还有另外一个问题

约束products_ibfk_1外键(userId)在更新级联上引用users (id)堆栈: Error: ER_NO_REFERENCED_ROW

我不确定我是否正确地理解了你的问题，但我想你是在问：

如何在实验室实验之间共享状态？

简单的解决办法是将var userId, payload, decoded, token;移动到“全局”范围的上层，这样就可以在任何地方访问它们。

不过，我的建议是，不要这样做，。您的测试用例应该是相互独立的。您应该能够添加测试、重新排序并删除它们，而不会影响其他测试用例。否则，你就会为自己制造一个维护噩梦。

如果需要多个测试用例中的资源，只需为每个测试创建一个新的资源：

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(...);
});

如果您需要更改一个资源，然后测试一些东西，那就是一个测试用例：

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

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