Uploading files with Capybara in RSpec tests
You can easily upload files with Capybara when testing with RSpec
Capybara is a great tool for testing your Rails app. Recently I had cause to test uploading files through a particular UI. Here is how you go about in Capybara.
attach_file("Upload Your File", Rails.root + "spec/fixtures/file.pdf")
What this tells Capybara is look for a file upload input with the label “Upload Your File” and then inserts the file specified.
I found I needed the Rails.root for the file to upload correctly.
In order to tidy up your tests I would recommend making a helper method called something like
pdf_upload_file which would return
Rails.root + "spec/fixtures/file.pdf"
