问题：通过契约进行的消费者驱动的合同测试

Question

我正在为大学项目编写一个小型程序。我想用契约框架来测试它。不幸的是，尽管没有错误，但没有为我创建Pact.json文件。我的消费者用Java语言编写。在下面，您可以看到我的javascript文件，控制台输出和我的package.json文件的源代码：

const {Pact} = require('@pact-foundation/pact');
const axios = require('axios');
const path = require('path');


describe('Pact Consumer', () => {
    const provider = new Pact({
        consumer: 'consumer',
        provider: 'producer',
        port: 1234,
        log: path.resolve(process.cwd(), 'logs', 'pact.log'),
        dir: path.resolve(process.cwd(), 'pacts'),
        logLevel: 'INFO',
    });

    beforeEach(() => provider.setup());
    jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
describe('consumer', () => {

    beforeEach
    (() =>

            provider.addInteraction({
                state: "valid date",
                uponReceiving: "a request for JSON data",
                withRequest: {
                    method: "GET",
                    path: "/test",
                    headers: { Accept: "application/json" },
                },
                willRespondWith: {
                    status: 200,
                    headers: { "Content-Type": "application/json" },
                    body:
                        {
                            name: 'Scherr',
                            surname: 'Valerian',
                            age: 28,
                        },

                },


        }),


    );

});



describe('test', () => {
it('should return the correct data', () => {

      axios.get('localhost:1234/test').then(response => {
        expect(response[0].name).toBe('Scherr');
        expect(response[0].surname).toBe('Valerian');
        expect(response[0].age).toBe(28);
    })


});
});
    afterEach(() => {
        provider.verify();
    });
        afterAll(() => {
        return provider.finalize();
    });
});

控制台输出：

我非常感谢您的帮助，并在此先致谢

我无法在这里没有日志告诉您，但是有一点可以肯定：您对axios.get和provider.verify的调用是承诺，并且没有正确执行，这意味着某些事情的执行会混乱或无法执行实际上执行。

仅将return加两个前缀即可解决该问题。
