Question

I am trying to check for images src in a HTML img tag using following code

extension.end_with?(/[.jpg|.gif|.png|.jpeg]/).should eq(true)

where
extension = “teaser_image610x450.jpg”

I also tried

 extension.end_with?(/[.]jpg|gif|png|jpeg/).should eq(true)

In both cases I am getting FALSE.
What is wrong with above code ?

Answer 1

You can use the following form:

extension.end_with?(".jpg",".gif",".png",".jpeg")

Or, something like this:

extensions = [".jpg",".gif",".png",".jpeg"]
if extensions.include?(extension)
  # do something here
end

I never saw this method being used with a regex before.
