You're too lazy to open a file, type the unit tests and hitting CTRL+S but you're not lazy to open the REPL, type the unit tests and hit capture? If you can't automate 100% of the REPL-into-test feature, if you need two mindsets/styles/etc, if you still need to "find the behaviour codified in a test", then you're just duplicating in the REPL the same workflow and results of writing the tests in a file. They need to overlap 100%. Now, if they do, then it's awesome.
