Question

我想在Angular中创建消费者Pact测试。

我已将pact依赖项放入package.json：

   "@pact-foundation/karma-pact": "2.1.9",
   "@pact-foundation/pact-node": "6.21.3",
   "@pact-foundation/pact-web": "7.2.0",

然后我更新了karma.conf.js：

module.exports = function (config) {
    config.set({
        basePath: '',
        frameworks: ['jasmine', '@angular-devkit/build-angular', 'pact'],
        plugins: [
            require('karma-jasmine'),
            require('karma-chrome-launcher'),
            require('karma-jasmine-html-reporter'),
            require('karma-coverage-istanbul-reporter'),
            require('@angular-devkit/build-angular/plugins/karma'),
            require('@pact-foundation/karma-pact')
        ],
        client: {
            clearContext: false // leave Jasmine Spec Runner output visible in browser
        },
        coverageIstanbulReporter: {
            dir: require('path').join(__dirname, '../coverage'),
            reports: ['html', 'lcovonly'],
            fixWebpackSourcePaths: true
        },
        angularCli: {
            environment: 'prod'
        },
        // load pact web module
        files: [
            '../node_modules/@pact-foundation/pact-web/pact-web.js'
        ],
        pact: [{
            cors: true,
            port: 1235,
            consumer: "ui",
            provider: "testservice",
            dir: "pacts",
            spec: 2
        }],
        proxies: {
            '/test-service/': 'http://127.0.0.1:1235/test-service/'
        },
        reporters: ['progress', 'kjhtml'],
        port: 9876,
        colors: true,
        logLevel: config.LOG_DEBUG,
        autoWatch: true,
        browsers: ['ChromeHeadless'],
        singleRun: true
    });
};

现在，当我开始ng测试时，Karma尝试启动Pact服务器并引发错误：

有人知道如何解决此错误吗？也许有想法如何找出缺失的路径？

Answer 1

我已找到此错误的原因-我们的企业防火墙阻止了二进制文件的下载。我已经手动下载了二进制文件，现在协议可以正常运行了。

Answer 2

我也遇到了这个问题（使用Mac OS），并且在主机文件中添加了主机名作为别名即可解决此问题。

您可以通过在终端中运行hostname来查找主机名。它类似于mymacbook.local。

然后在/etc/hosts文件中添加/编辑这些条目，使它们看起来像这样：

127.0.0.1   localhost mymacbook.local
::1         localhost mymacbook.local

启动Pact服务器会引发Pact二进制错误
