java 将选项传递给 chrome 驱动程序 selenium

Passing options to chrome driver selenium

提问by Lazadon

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?

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？

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

I also tried

我也试过

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

Output

输出

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

受此Chromedriver 票证（关于silent选项）的暗示，我查看了 的来源ChromeDriverService.java，并找到了对"webdriver.chrome.logfile".

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

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

I start javawith the following parameters (Linux / Mac):

我从java以下参数开始（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

If you're on Windows:

如果您使用的是 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

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.

我的类路径 ( -cp)的组成说明：我的测试位于“$DIR/output”目录中。Selenium jar 文件放在“$DIR/bin/selenium-server-standalone-2.33.0.jar”中。“AllTests”是我包含的类的名称public static void main(String[] args)- 这将启动我的测试。

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.

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

When I was setting chrome up with

当我设置 chrome 时

  selenium-chrome-driver-2.48.2.jar
  chromedriver 2.20
  selenium-java-2.48.2.jar

none of the above answers worked for me, Since I see some of the answers are a few years old, I will post what worked for me.

    ChromeOptions chromeOptions = setupChromeOptions();
    System.setProperty("webdriver.chrome.logfile", "\path\chromedriver.log");
    System.setProperty("webdriver.chrome.driver", "\path\chromedriver.exe");
    System.setProperty("webdriver.chrome.args", "--disable-logging");
    System.setProperty("webdriver.chrome.silentOutput", "true");
    driver = new ChromeDriver(chromeOptions);

  selenium-chrome-driver-2.48.2.jar
  chromedriver 2.20
  selenium-java-2.48.2.jar

以上答案都不适合我，因为我看到一些答案已经有几年了，我会发布对我有用的内容。

    ChromeOptions chromeOptions = setupChromeOptions();
    System.setProperty("webdriver.chrome.logfile", "\path\chromedriver.log");
    System.setProperty("webdriver.chrome.driver", "\path\chromedriver.exe");
    System.setProperty("webdriver.chrome.args", "--disable-logging");
    System.setProperty("webdriver.chrome.silentOutput", "true");
    driver = new ChromeDriver(chromeOptions);

Try "--disable-logging" instead.

试试“ --disable-logging”。

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

As of Selenium 3 at least, you can use ChromeDriverService and its inner class Builder to be able to launch the driver in silent mode.

至少从 Selenium 3 开始，您可以使用 ChromeDriverService 及其内部类 Builder 来以静默模式启动驱动程序。

A oneliner for that:

一个oneliner：

new ChromeDriver(new ChromeDriverService.Builder().withSilent(true).build());

The constructor is straight-forward, you create a new service builder setting silent to true (that's the critical part) and you finally build it into a ChromeDriverService which is required by ChromeDriver's constructor.

构造函数很简单，您创建了一个新的服务构建器，设置为 true（这是关键部分），最后将其构建到 ChromeDriver 的构造函数所需的 ChromeDriverService 中。
