将选项传递给chrome驱动程序selenium [英] Passing options to chrome driver 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，它可以正常工作。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

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

输出

已启动ChromeDriver端口= 26703版本= 23.0.1240.0
log = / Brett / workspace / TestNG / chromedriver.log

推荐答案

这是 Chromedriver ticket （关于 silent 选项），我查看了 ChromeDriverService .java ，并找到对webdriver.chrome.logfile的引用。

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".

添加 -Dwebdriver.chrome后。 logfile =/ dev / null到我的 java 命令，日志再次变得可读：无用的ChromeDriver日志消失了，而 System.out.println 调用和异常仍显示在控制台中。

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.

我启动 java ，包含以下参数（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

如果你在Windows上：

If you're on Windows:

set 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.exe" ^
-Dwebdriver.chrome.args="--disable-logging" ^
-Dwebdriver.chrome.logfile=NUL ^
AllTests

我的类路径的组成说明（ -cp ）：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是我的类的名称，包含 public static void main（String [] args） - 这将启动我的测试。

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，可根据您的需要进行调整。为方便起见（在shell / batch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.
