yup @timgilbert that's exactly what capture-output does, It should also be enabled by default, so you don't need to add it yourself to tests.edn

if it's not working as it should could you file an issue?

note that you can disable this behavior with --no-capture-output or in tests.edn with :kaocha.plugin.capture-output/capture-output? false

(a good way to find out about configuration flags like this is with --print-config, that will show you your tests.edn, but normalized and with these defaults merged in)

Another PSA, there are still some issues with the Junit-xml output, the next release should make errors and failures render in a much more useful way. It'll also contain some affordances to work with kaocha-cljs.
