SessionNotCreatedError: session not created Error in Protractor automation

Question

我有一个 angular 应用程序，我正在尝试对其进行运行 Protractor 自动化测试。但是当我尝试运行自动化测试时，出现以下错误。我有 Chrome 浏览器 86 并将 chrome 86 chromedriver.exe 放在 node_moules/protractor/selenium/ 下。但我仍然收到以下错误。

不知道在哪里设置请求量角器拾取的路径chrome86 驱动程序。任何帮助表示赞赏。

Answer 1

当我将 protractor/config.json 更改为指向 86

的最新 chromedriver 时，我能够解决问题

{
  "webdriverVersions": {
    "selenium": "2.52.0",
    "chromedriver": "86.0.4240.22",
    "iedriver": "2.52.0"
  }
}

然后手动下载文件放在protractor/selenium里，把扩展名改成chromedriver_86.0.4240.22.exe

Answer 2

无需下载每个新版本的 chromedriver 即可自动执行此操作是让 webdriver-manager 软件包完成其工作。

node node_modules/protractor/bin/webdriver-manager update
protractor <your_configuration_js>

注意：请参阅上面如何调用 webdriver-manager，它使用项目 npm 模块中的本地版本（而不是全局版本）。它可以很好地同步以下设置。

如果您在 量角器配置 中使用了上述步骤，则必须启用此键。这不需要每次开始测试时 use/execute webdriver-manager start。
