使用AShot和Watir截图

Question

我正在尝试使用带有Selenium的AShot来截图。

require 'selenium/webdriver'
require 'javalib/ashot-1.5.4.jar'

driver_path = 'C:\ProgramData\chocolatey\lib\chromedriver\tools\chromedriver.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:\data\google_screenshot.png'
File.write(test_pod_name, png)
puts "Writing to: #{test_pod_name}"

driver.close

但是我收到了这个错误消息：

有趣的是，错误转储并没有引用AShot --但是错误是由AShot行产生的。

Answer 1

Selenium中有一个开放的方法--webdriver方法，用于截图。您可以使用类似于

@driver.save_screenshot('c:\data\google_screenshot.png')
