我正在配置运行 Protractor 测试，以下是 Azure devops 中添加的步骤

当我运行此管道时，它会在 webdriver-manager start --standalone 处受到打击。没有出来，所以它运行下一个命令开始测试。

Answer 1

没有出来，所以它运行下一个命令开始测试。

net 命令是任务Run Test Cases，对吧？如果是，我们可以单击任务并展开选项卡Control Options 并确保字段Run this task 设置为Even if a previous task has failed, unless the build was canceled。

那么如果任务Webdriver Start失败，管道会继续运行下一个任务Run Test Cases。

更新1

没有出来，所以它运行下一个命令开始测试。

最初的问题已经解决了。

由于您尚未启动或 webdriver 未正确启动，我们可以看到错误问题：ECONNREFUSED connect ECONNREFUSED 127.0.0.1:4444。如果上一个任务成功运行Webdriver，我们就不会看到错误信息了。

我们需要确保 Webdriver 启动，然后运行 ​​Protractor 测试。

Answer 2

我发现了问题所在。我们不需要明确的步骤来启动 Webdriver，而且我必须在 config.js 中注释一行
