I use a method where I take the text on the screen and put it into a master
reference file.
Then i write the test screen text into a compare file
Then I use FileUtils to compare the two files.
You could use HTML instead of text for the scrape.
Whey text or html instead of bitmaps. I replay on different computers and
browsers which can vary the quality of the captures.
Rough Example:
require 'fileutils'
def archiveTheScreenAsMaster()
# Get the text from the screen in question
sScreenText = browser.text.to_s
# Store as a file in the test archive as a master
myFile = File.new("masterScreen.txt","w:UTF-8")
myFile.puts sScreenText.to_s
myFile.close
end
def compareTheScreen()
sScreenText = browser.text.to_s
# Store as a current view file to compare
myFile = File.new("todaysSceen.txt","w:UTF-8")
myFile.puts sScreenText.to_s
myFile.close
# Now compare with FileUtils
if FileUtils.compare_file(masterScreen.txt","todaysSceen.txt") then
puts 'PASS'
else
puts 'FAIL"
end
end
