Robotframework桌面应用程序测试安装失败

Question

我想通过RobotFramework测试桌面电子应用程序。我下载了Selenium2Library，在网上看到了一些关于这方面的文章。我使用以下文本为变量创建vars.py：

"chromeOptions": {
                   "binary": "/Users/amar/Downloads/name-of-application-staging.app/Contents/MacOS/name-of-application-staging",
                    "args": ["--headless", "--no-sandbox"]
               }
              

*** Settings ***
Library    Selenium2Library
Variables    vars.py

*** Test Cases ***
Foo
  Create Webdriver    Remote    desired_capabilities=${binary_location}    command_executor=http://localhost:9515
  click element  hehe_element

robot test.robot

    WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist
    (Driver info: chromedriver=2.43.600229 (3fae4d0cda5334b4f533bede5a4787f7b832d052), platform=Mac OS X 10.13.6 x86_64)

Second keyword "Click element" never starts.
I'm using macOS.

Version of chrome: `Version 70.0.3538.67 (Official Build) (64-bit)`

Version of chromedriver: `ChromeDriver 2.43`


After trying to start through .py i get this error:
     Traceback (most recent call last):

Answer 1

请尝试以下代码：

def build_chrome_options():
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument("--no-sandbox")
    chrome_options.add_argument("--headless")
    chromeOptions.binary_location='/Users/amar/Downloads/name-of-application-staging.app/Contents/MacOS/name-of-application-staging'

    return chrome_options
