From ed83a1cc0929bc3ffae234920b3e0414636b2751 Mon Sep 17 00:00:00 2001 From: Ruben Bridgewater Date: Mon, 9 Mar 2020 13:08:52 +0100 Subject: [PATCH] test: refactor and simplify test-repl-preview Use an object to indicate which part belongs to the input and which to the output. On top of that this also simplifies the expected output by automatically inserting the default repl line for previews and by automatically checking for the correct output line length.
