What this snippet does

Running tests in a stage makes a failing suite fail the build itself.

Expected output

Why practise typing this

Typing multi-stage builds code builds muscle memory for the symbols and indentation Docker uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
