Question

我可以使用以下命令在Firefox上运行我的测试：

 nightwatch -t tests/test4.js

我的nightwatchjs.json配置文件：

{
  "src_folders" : ["tests"],
  "output_folder" : "reports",
  "custom_commands_path" : "",
  "custom_assertions_path" : "",
  "globals_path" : "",

  "selenium" : {
    "start_process" : true,
    "server_path" : "selenium-server-standalone-2.44.0.jar",
    "log_path" : "",
    "host" : "127.0.0.1",
    "port" : 4444,
    "cli_args" : {
      "webdriver.chrome.driver" : "drivers/chromedriver"
    }  
  },

  "test_settings" : {
    "default" : {
      "launch_url" : "http://localhost",
      "selenium_port"  : 4444,
      "selenium_host"  : "localhost",
      "silent": true,
      "screenshots" : {
        "enabled" : false,
        "path" : ""
      },
      "desiredCapabilities": {
        "browserName": "firefox",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    },

    "chrome" : {
      "desiredCapabilities": {
        "browserName": "chrome",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    }
  }
}

但是，我无法使用Chrome运行测试。这是命令：

nightwatch -t tests/test4.js -e chrome --verbose

输出：

INFO Request: POST /wd/hub/session 
 - data:  {"desiredCapabilities":{"browserName":"chrome","javascriptEnabled":true,"acceptSslCerts":true,"platform":"ANY","name":"Test4"}} 
 - headers:  {"Content-Type":"application/json; charset=utf-8","Content-Length":127}
ERROR Response 500 POST /wd/hub/session{ sessionId: null,
  status: 13,
  state: 'unhandled error',
  value: 
   { message: null,
     localizedMessage: null,
     cause: null,
     class: 'java.util.concurrent.TimeoutException',
     hCode: 1023736867,
     screen: null },
  class: 'org.openqa.selenium.remote.Response',
  hCode: 31447144 }

由于某些原因，相同的主要配置选项适用于Firefox，但不适用于Chrome。有没有人有同样的问题？

谢谢，保罗

保罗！）尝试在chrome“desiredCapabilities”块中使用selenium CLI参数。并指定chromedriver二进制文件的路径。或者你可以在硒块中加入它来制作它

"cli_args" : {
      "webdriver.chrome.driver" : "<path to chromedriver>"
    }

http://nightwatchjs.org/guide#settings-file了解更多信息。

但我更喜欢使用bash脚本运行selenium服务器

#!/bin/bash
all="false"
chrome="false"
firefox="false"
phantom="false"
for var in "$@"
do
    if [ "$var" == "firefox" ];
    then
        firefox="true"
    fi
    if [ "$var" == "chrome" ];
    then
        chrome="true"
    fi
    if [ "$var" == "phantomjs" ];
    then
        phantom="true"
    fi
    if [ "$var" == "all" ];
    then
        all="true"
        firefox="true"
        chrome="true"
        phantom="true"
    fi
done

if [ "$firefox" == "true" ] && [ "$phantom" == "true" ] && [ "$chrome" == "true" ];
then
    all="true"
fi

if [ "$#" -eq 0 ];
then
    firefox="true"
fi

echo Selenium will started for chrome: "$chrome"
echo Selenium will started for firefox: "$firefox"
echo Selenium will started for phantomjs: "$phantom"
echo Selenium will started for all browsers: "$all"

if [ "$chrome" == "true" ];
then
    nohup java -jar lib/selenium-server-standalone-2.44.0.jar -Dwebdriver.chrome.driver="lib/chromedriver"&
    echo $! > sel_pid_head
    echo "Selenium server for Chrome and FireFox started"
    chrome="false"
    firefox="false"
fi

if [ "$firefox" == "true" ];
then
    nohup java -jar lib/selenium-server-standalone-2.44.0.jar&
    echo $! > sel_pid_head
    echo "Selenium server for FireFox started"
    firefox="false"
fi

if [ "$all" == "true" ];
then
    nohup java -jar lib/selenium-server-standalone-2.44.0.jar -role hub -port 4455&
    echo $! > sel_pid_headless
    echo "Selenium server for PhantomJS started"
    echo "Waiting 3 sec to register ghost driver into Selenium hub"
    sleep 3
    nohup phantomjs --webdriver=8080 --webdriver-selenium-grid-hub=http://127.0.0.1:4455&
    echo "PhantomJS registred in Selenium Server"
    echo $! > ghost_pid
    phantom="false"
    all="false"
fi

if [ "$phantom" == "true" ]
then
    nohup java -jar lib/selenium-server-standalone-2.44.0.jar -role hub -port 4455&
    echo $! > sel_pid_headless
    echo "Selenium server for PhantomJS started"
    echo "Waiting 3 sec to register ghost driver into Selenium hub"
    sleep 3
    nohup phantomjs --webdriver=8080 --webdriver-selenium-grid-hub=http://127.0.0.1:4455&
    echo "PhantomJS registred in Selenium Server"
    echo $! > ghost_pid
    phantom="false"
fi

在Mac OS上使用Nightwatchjs在Chrome中启动测试：“连接被拒绝了！是否启动了selenium服务器？”
