Mismatch errors found
See original GitHub issueI have created two sample projects to test out backstopjs, but I am failing on both with error of “Mismatch errors found” when I run the backstop test command.
After installing it globally I ran the backstop init command that created the backstop_data folder and its subfolders on my root.
Then I executed the backstop test but it returns with missmatch errors and loads the html report in the browser. But the bitmaps_test director is never created either.
On one of the sample projects I ran has the same project structure and content as the one on https://css-tricks.com/automating-css-regression-testing/ site, but using the backstop test instead and executing the command on the root. The scenarios code is also the same as suggested on that page. So the url path is the same as suggested on that page.
Any suggestions what I may have done wrong?

I just had a thought. Did you try running
pkill -f "(chrome)?(--headless)"That would insure there are no zombie versions of chrome running (which can sometimes happen and cause weird failures). Maybe that helps?
Sorry, Nothing wrong on your side, my bad, it was a path error in the url setting. I tested it out on the same project as on the CSS-Tricks article https://css-tricks.com/automating-css-regression-testing/ page. But I changed the url path, as this time I ran the backstop init on the root and the index.html is on the root of that project.
Thanks for your help 😃
