将选项传递给 chrome 驱动程序 selenium

问题描述

我正在尝试禁用 Chrome 控制台的输出.如果我通过 --start-maximized 选项它工作正常.我可能有错误的命令?

I am trying to disable the output to the console for chrome. If I pass the --start-maximized option it works fine. I may have the wrong command?

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--silent"));
chrome = new ChromeDriver(_chromeservice,capabilities);

我也试过了

 ChromeOptions options = new ChromeOptions();
 options.addArguments("silent");
 chrome = new ChromeDriver(options);

输出

启动 ChromeDriver 端口=26703 版本=23.0.1240.0日志=/Brett/workspace/TestNG/chromedriver.log[1214/161331:ERROR:ipc_sync_channel.cc(378)] 取消挂起的发送[1214/161331:ERROR:ipc_sync_channel.cc(378)] 取消挂起的发送[1214/161331:ERROR:ipc_sync_channel.cc(378)] 取消挂起发送块引用

推荐答案

提示 Chromedriver ticket(关于 silent 选项)，我查看了 ChromeDriverService.java，找到了的引用"webdriver.chrome.logfile".

Hinted by this Chromedriver ticket (about the silent option), I looked in the source of ChromeDriverService.java, and found a reference to "webdriver.chrome.logfile".

将 -Dwebdriver.chrome.logfile="/dev/null" 添加到我的 java 命令后，日志再次变得可读:无用的 ChromeDriver 日志不见了，而 System.out.println 调用和异常仍然显示在控制台中.

After adding -Dwebdriver.chrome.logfile="/dev/null" to my java command, the logs became readable again: The usless ChromeDriver logs were gone, while theSystem.out.println calls and exceptions are still shown in the console.

我用以下参数启动java(Linux/Mac):

I start java with the following parameters (Linux / Mac):

DIR=path/to/dir/containing/selenium/and/stuff
cd "$DIR" && java -cp "$DIR
:$DIR/output
:$DIR/bin/selenium-server-standalone-2.33.0.jar" 
-Dwebdriver.chrome.driver="$DIR/bin/chromedriver" 
-Dwebdriver.chrome.args="--disable-logging" 
-Dwebdriver.chrome.logfile="/dev/null" 
AllTests

如果您使用的是 Windows:

If you're on Windows:

set DIR=path	odircontainingseleniumandstuff
cd "%DIR%" && java -cp "%DIR%;%DIR%output;%DIR%inselenium-server-standalone-2.33.0.jar" ^
-Dwebdriver.chrome.driver="%DIR%inchromedriver.exe" ^
-Dwebdriver.chrome.args="--disable-logging" ^
-Dwebdriver.chrome.logfile=NUL ^
AllTests

<小时>

我的类路径(-cp)的组成说明:我的测试位于$DIR/output"的目录中.Selenium jar 文件放在$DIR/bin/selenium-server-standalone-2.33.0.jar"中.AllTests"是包含 public static void main(String[] args) 的类的名称 - 这会启动我的测试.

Explanation for the composition of my classpath (-cp): My tests are located in a directory at "$DIR/output". The Selenium jar file is placed in "$DIR/bin/selenium-server-standalone-2.33.0.jar". "AllTests" is the name of my class containing public static void main(String[] args) - this launches my tests.

其他参数不言自明，请根据需要进行调整.为方便起见(在 shell/批处理脚本中使用)，我在变量 DIR 中声明了公共目录.

The other parameters are self-explanatory, adjust it to your needs. For convenience (used in a shell/batch script), I've declared the common directory in a variable DIR.
