Is it possible to tell clojure.test to stop at the first test that fails?
not directly
"fail-fast" is a commonly found feature in alternative runners
a cheap trick you can do if needing something quick is wrapping a given is in assert
and if you like running tests from the repl, it can be easily done in pure clojure.test: https://github.com/reducecombine/.lein/blob/f01aec663ff4ac8f8e83f8eca93a13b2cf99aa4b/scripts/vemv.clj#L67-L79
(`reduced` does the fail-fasting)
I invoke that from my repl (aided by a yasnippet) daily
Yes, REPL is it. Thank you very much!
