调整量角器配置以在非无头模式下进行调试

Question

执行量角器测试时，它在--headless模式下成功，但是当我删除--headless选项时，它失败了，指出：user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir。

如您所见，我没有使用那个特定的论点，所以我不知道该怎么做。

更新：当crome浏览器选项卡打开时，data:,位于地址栏中。

错误

此错误的原因是在不同的配置文件上运行多个 chrome 浏览器实例。当量角器启动测试时，Chrome 会创建一个默认配置文件，并在该配置文件上运行测试。如果有多个 chrome 实例正在运行，Chrome 会在 --user-data-dir 参数中询问您的用户定义的配置文件。

这意味着在开始测试之前，您应该确保没有挂起的 chrome 进程正在运行。检查正在运行的进程并删除这些进程。然后，请确保在配置文件中添加如下所示的onComplete部分，以便在测试完成后关闭Chrome浏览器实例。这是代码片段。

onComplete: async () => {
await browser.driver.close();
await browser.driver.quit();
}

尝试一次！可能会解决您面临的问题。
