我正在使用 MEAN 堆栈和 Webdriver 构建一个应用程序进行测试。
目前我正在使用 Mocha 的 beforeEach 和 afterEach 钩子在测试之间清理数据库,例如:
describe('Links', function() {
// drop DB collections
beforeEach(function(done){
//create database objects
});
afterEach(function(done){
// drop DB collections
});
});
有没有办法设置 wdio.conf.js 以便在每次测试之前和之后自动发生这种情况?配置的
before:
和 after: function() {}
作为 beforeAll / afterAll 运行,而不是针对每个测试运行。
是的,请参阅此网址:http://webdriver.io/guide/testrunner/gettingstarted.html
如果启动 wdio 配置,将生成一个名为 wdio.conf.js 的文件,此文件中存在在测试之后或之前启动脚本的函数,我显示包含此文件的函数示例:
// =====
// Hooks
// =====
// Run functions before or after the test. If one of them returns with a promise, WebdriverIO
// will wait until that promise got resolved to continue.
//
// Gets executed before all workers get launched.
onPrepare: function() {
// do something
},
//
// Gets executed before test execution begins. At this point you will have access to all global
// variables like `browser`. It is the perfect place to define custom commands.
before: function() {
// do something
},
//
// Gets executed after all tests are done. You still have access to all global variables from
// the test.
after: function(failures, pid) {
// do something
},
//
// Gets executed after all workers got shut down and the process is about to exit. It is not
// possible to defer the end of the process using a promise.
onComplete: function() {
// do something
}
重要的是,如果您异步启动脚本,并且在清理数据库时等待回调,那么您需要一个承诺,否则下一步钩子将启动而不等待上一个函数钩子,例如:
onPrepare: function() {
return new Promise(function(resolve, reject) {
sauceConnectLauncher({
username: 'the_pianist2',
accessKey: '67224e83a-1cf7440d-8c88-857c4d3cde49',
}, function (err, sauceConnectProcess) {
if (err) {
return reject(err);
}
console.log('success');
resolve();
});
});
},
