Edge 特定功能

微软Edge是用Chromium实现的，最早支持版本是v79. 与Chrome类似, Edge驱动的主版本号必须与Edge浏览器的主要版本匹配.

在 Chrome 页面 上找到的所有capabilities和选项也适用于Edge.

选项

Capabilities common to all browsers are described on the Options page.

Capabilities unique to Chromium are documented at Google’s page for Capabilities & ChromeOptions

使用基本定义的选项启动 Edge 会话如下所示:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    driver.quit()

    @driver = Selenium::WebDriver.for :edge, options: options
  end

      let options = new edge.Options();
      driver = await env.builder()
        .setEdgeOptions(options)
        .setEdgeService(new edge.ServiceBuilder(edgedriver.binPath()))
        .build();

Arguments

The args parameter is for a list of command line switches to be used when starting the browser. There are two excellent resources for investigating these arguments:

• Chrome Flags for Tooling
• List of Chromium Command Line Switches

Commonly used args include --start-maximized and --headless=new and --user-data-dir=...

Add an argument to options:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    driver.quit()

  end

        .build();

Start browser in a specified location

The binary parameter takes the path of an alternate location of browser to use. With this parameter you can use chromedriver to drive various Chromium based browsers.

Add a browser location to options:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Add extensions

The extensions parameter accepts crx files. As for unpacked directories, please use the load-extension argument instead, as mentioned in this post.

Add an extension to options:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Keeping browser open

Setting the detach parameter to true will keep the browser open after the process has ended, so long as the quit command is not sent to the driver.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        .build();

Excluding arguments

MSEdgedriver has several default arguments it uses to start the browser. If you do not want those arguments added, pass them into excludeSwitches. A common example is to turn the popup blocker back on. A full list of default arguments can be parsed from the Chromium Source Code

Set excluded arguments on options:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    it('Basic Edge test', async function () {
      await driver.get('https://www.google.com');
    });
  });

Service

Examples for creating a default Service object, and for setting driver location and port can be found on the Driver Service page.

Log output

Getting driver logs can be helpful for debugging issues. The Service class lets you direct where the logs will go. Logging output is ignored unless the user directs it somewhere.

File output

To change the logging output to save to a specific file:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        EdgeDriverService service = new EdgeDriverService.Builder()

    driver = webdriver.Edge(service=service)

        {

      expect(File.readlines(file_name).grep(/\[DEBUG\]:/).any?).to eq true

Console output

To change the logging output to display in the console as STDOUT:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    public void disableBuildChecks() throws IOException {

Log level

There are 6 available log levels: ALL, DEBUG, INFO, WARNING, SEVERE, and OFF. Note that --verbose is equivalent to --log-level=ALL and --silent is equivalent to --log-level=OFF, so this example is just setting the log level generically:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        String expected = "[WARNING]: You are using an unsupported command-line switch: --disable-build-check";
        Assertions.assertTrue(fileContent.contains(expected));

    driver = webdriver.Edge(service=service)

      @driver = Selenium::WebDriver.for :edge, service: service

Log file features

There are 2 features that are only available when logging to a file:

• append log
• readable timestamps

To use them, you need to also explicitly specify the log path and log level. The log output will be managed by the driver, not the process, so minor differences may be seen.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Disabling build check

Edge browser and msedgedriver versions should match, and if they don’t the driver will error. If you disable the build check, you can force the driver to be used with any version of Edge. Note that this is an unsupported feature, and bugs will not be investigated.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin
