I am using getElementsByTagName in order to get a list of images on
the page, and then checking the alt text against that in an excel
spreadsheet.
This works, unless there is only 1 img on the page, in which case I
get the error "undefined local variable or method `i' for #<Object:
0x30f9e4>"
I assume that this is because getElementsByTagName isn't returning an
array that I can use the "each" method ?
Any ideas how to solve this?
Here is the code:
def checkIMG(browser, record)
imgLocation = @site + record['Image Location']
altText = record['Alt Text']
locationFound = 0
imgs=
browser.document.body.parentElement.getElementsByTagName("img")
imgs.each do |i|
if i.src == imgLocation
@html.addtoReport("Location", 'PASS', "A:
'#{i.src}'<br>E: '#{imgLocation}'")
#puts " Location correct. Actual '#{i.src}' expected
is '#{imgLocation}'"
locationFound = 1
if i.alt == altText
@html.addtoReport("Alt Text", 'PASS', "A:
'#{i.alt}'<br>E: '#{altText}'")
#puts " AltText correct. Actual '#{i.alt}' expected
is '#{altText}'"
else
@html.addtoReport("Alt Text", 'FAIL', "A:
'#{i.alt}'<br>E: '#{altText}'")
puts " IMG ERROR '#{imgLocation}'"
puts " ALT ERROR Actual '#{i.alt}'"
puts " ALT ERROR Expected '#{altText}'"
end
end
end
