使用AShot和Watir拍摄屏幕截图

Question

我正在尝试使用带有Selenium的AShot来进行屏幕截图。

require 'selenium/webdriver'
require 'javalib/ashot-1.5.4.jar'
driver_path = 'C:ProgramDatachocolateylibchromedrivertoolschromedriver.exe'
Selenium::WebDriver::Chrome::Service.driver_path = driver_path
base_url = 'https://www.google.com/'
driver = Selenium::WebDriver.for :chrome
driver.navigate.to base_url
ashot = Java::RuYandexQatoolsAshot::AShot.new
png = ashot.takeScreenshot(driver)
test_pod_name = 'c:datagoogle_screenshot.png'
File.write(test_pod_name, png)
puts "Writing to: #{test_pod_name}"
driver.close

但我收到了这个错误消息：

有趣的是，错误转储没有引用AShot，但错误源于安装AShot的行。

Selenium webdriver方法中有一个用于捕获屏幕截图的开放方法。你可以使用类似的东西

@driver.save_screenshot('c:datagoogle_screenshot.png')
