When releasing a C# MVC website through Devops release management the bundling failed. This caused the CSS file not to load on the released website, causing the UI to render incorrectly.
To ensure this doesn't happen again I want to run a selenium test on the build and take a screenshot of the homepage. I would then like to compare the screenshot with a specified image (of how the homepage should look) on the build, and fail if the images don't match.
What can I use to compare two images (on live screenshot and one saved image) on the CI Devops build server?
