怎么利用 ChromeDriver 和 Selenium对 CEF应用进行自动化测试-java实现
Overview
ChromeDriver and Selenium are tools for automated testing of Chromium-based applications. The tests themselves can be written in a number of languages including Java, JavaScript and Python. ChromeDriver communicates with the Chromium-based application using the DevTools remote debugging protocol (configured via the --remote-debugging-port=XXXX command-line flag passed to the application). Detailed ChromeDriver/Selenium usage information is available here:

Java Tutorial
This tutorial demonstrates how to control the cefclient sample application using the Java programming language on Windows. Usage on other platforms and with other CEF-based applications is substantially similar.
Install the Java JDK and add its bin directory to your system PATH variable.
Create a directory that will contain all files. This tutorial uses c:\temp.
Download ChromeDriver from https://sites.google.com/a/chromium.org/chromedriver/downloads and extract (e.g. chromedriver_win32.zip provides chomedriver.exe). This tutorial was tested with version 2.14.
Download selenium-server-standalone-x.y.z.jar from http://selenium-release.storage.googleapis.com/index.html. This tutorial was tested with version 2.44.0.
Download a CEF binary distribution client from Downloads and extract (e.g. cef_binary_3.2171.1979_windows32_client.7z).
Create Example.java:
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
public class Example {
public static void main(String[] args) {
// Path to the ChromeDriver executable.
System.setProperty("webdriver.chrome.driver", "c:/temp/chromedriver.exe");
ChromeOptions options = new ChromeOptions();
// Path to the CEF executable.
options.setBinary("c:/temp/cef_binary_3.2171.1979_windows32_client/Release/cefclient.exe");
// Port to communicate on. Required starting with ChromeDriver v2.41.
options.addArguments("remote-debugging-port=12345");
WebDriver driver = new ChromeDriver(options);
driver.get("http://www.google.com/xhtml");
sleep(3000); // Let the user actually see something!
WebElement searchBox = driver.findElement(By.name("q"));
searchBox.sendKeys("ChromeDriver");
searchBox.submit();
sleep(3000); // Let the user actually see something!
driver.quit();
}
static void sleep(int time) {
try { Thread.sleep(time); } catch (InterruptedException e) {}
}
}
Your directory structure should now look similar to this:
c:\temp\
cef_binary_3.2171.1979_windows32_client\
Release\
cefclient.exe (and other files)
chromedriver.exe
Example.java
selenium-server-standalone-2.44.0.jar
- Compile Example.java to generate Example.class:
> cd c:\temp
> javac -cp ".;*" Example.java
- Run the example:
> cd c:\temp
> java -cp ".;*" Example
When the example is run ChromeDriver will:
Output to the console:
Starting ChromeDriver 2.14.313457 (3d645c400edf2e2c500566c9aa096063e707c9cf) on port 28110
Only local connections are allowed.
Launch cefclient.exe.
Submit a Google search for "ChromeDriver".
Close cefclient.exe.
