使用selenium - java时，在var/tmp内创建带有屏幕截图[SomeRandomnumber.png]的文件名

import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.apache.commons.io.FileUtils;
import java.io.File;
import java.io.IOException;

System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");

WebDriver driver = new ChromeDriver();

driver.get("https://www.example.com");

File screenshotFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

String fileName = "SomeRandomnumber.png";
String filePath = "/var/tmp/" + fileName;

try {
    FileUtils.copyFile(screenshotFile, new File(filePath));
} catch (IOException e) {
    e.printStackTrace();
}
