我正在从事一个更像概念证明的项目。实际上,对我来说,这是一个POC,因为我确信它已经完成过。
我正在尝试在Visual Studio Code上使用Cucumber.js,Appium服务器/客户端,节点和Javascript。
有点背景。我是Java语言的新手,但对BDD / Cucumber和Appium的自动测试并不陌生。
我刚开始项目时遇到了障碍,我不明白哪里出了问题,或者从这里去哪里。搜索互联网并没有带我到任何地方-可能没有在正确的位置使用正确的关键字进行搜索。
让我解释一下。我已经在Visual Studio代码的工作区中创建了功能文件,如下所示
Feature: Change Font Size
Scenario: Set Font Size to Default
Given that I am on Font Size option
When I click the default option
Then The font size should be set to default
Scenario: Set Font Size to Small
Given that I am on Font Size option
When I click the small option
Then The font size should be set to small
我已经通过使用以下命令生成了粘合代码
Windows PowerShell
Copyright (C) Microsoft Corporation. All rights reserved.
Try the new cross-platform PowerShell https://aka.ms/pscore6
PS C:\Projects\VisualStudioCode\CucumberAppium> node_modules/.bin/cucumber-js
很好,因为这会生成我添加到我的js文件中的粘合代码/步骤定义。我的js文件如下所示。在运行了cucumber-js命令(如上所述)后,按原样获取了此代码]
const {Given,When,Then} = require('cucumber');
Given('that I am on Font Size option', function () {
// Write code here that turns the phrase above into concrete actions
return 'pending';
});
When('I click the default option', function () {
// Write code here that turns the phrase above into concrete actions
return 'pending';
});
Then('The font size should be set to default', function () {
// Write code here that turns the phrase above into concrete actions
return 'pending';
});
When('I click the small option', function () {
// Write code here that turns the phrase above into concrete actions
return 'pending';
});
Then('The font size should be set to small', function () {
// Write code here that turns the phrase above into concrete actions
return 'pending';
});
我还没有添加任何代码,但是当我运行此Run->无需调试运行时,我期望发生的至少是什么-因为没有代码。
但是我遇到了错误(如下所述)

我知道我可能忽略了某些事情。
如果有人能指出我正确的方向,我将非常感激。

谢谢!
您应该让黄瓜赛跑者知道步骤定义文件的位置。您可以使用nightwatchjs here找到一个实施良好的Cucumberjs项目。这可能有太多细节,但可以帮助您理解。
