Project is a mixture of clj, cljs, cljc, not sure if that matters.

This regression is very recent (I only noticed it last night when I rebooted Intellij after a few days, and also noticed Cursive uses nRepl now).

When the expected / result in a test is over a certain size there is no marker shown for test result, and no diff available in the case of failed tests. Finally, some output is written to the REPL, e.g.

Ran 2 tests containing 9 assertions.

There is no prn statement anywhere in the code, that is coming from the test runner.

Screenshots follow of four cases, each case is the editor pane post-test run (and other tests in the same ns showing marker / diff as expected):

1. Test passes, output muted

2. Test fails, output muted

3. Test passes, output fine (all I have done is reduce the size of both expected and result)

4. Test fails, output fine (same as [3] but failing test)

Test follows:

Anyone else experiencing this? It's killing my productivity.

[voj]

I've got this too. When the asserted result is too large, it's printed partially on the REPL, and no result markers are drawn, no diff is available.

Running a test on the command line with lein test still works fine.

• Clojure 1.9.0

My colleague does not have this problem, and he is using the same Clojure and Intellij but his Cursive is

[voj]

Downgrading to v1.8.0-2018.3 did indeed fix this problem for me.

[d-t-w]

Thanks @voj, I'm on the EAP as well so perhaps that it and it'll get wrapped up in a stable release.

[jsbed]

+1 It's been happening to me as well. Doesn't seem to be related to Clojure's version.

[MattVane]

+1 its definitely the version of cursive (and is present in the 1.8.2 EAP), but I'm on IDEA 2019.1, so no downgrade available without taking everything back a version.... :(
It seems to be any test with a lot of output causes some sort of overflow into the REPL, which then means cursive can't parse the output and display test status in the gutter,

I'm using test-refresh with the :test-refresh/focus selector for now, but its nowhere near as good... Please please fix!

[neuromantik33]

+1 So annoying. Can't downgrade either since I'm running 2019.1 as well

[cursive-ghost]

My apologies for the delay with this - this is fixed for the next build.

This code actually hasn't changed in Cursive for a long time. My theory is that upgrading Cursive caused a new version of lein to be used, which caused a new version of nREPL to be used, and due to nREPL's new streaming output this caused some messages to be partially sent when large, whereas previously they were completely sent.

I'll try to get this out ASAP, I know this has been annoying.

[d-t-w]

Thanks Colin! If it helps in any way I did notice that the version of nREPL being used by Cursive did bump up to 0.4 before the Cursive release that specifically included that upgrade. So sounds like you might be on the right track.

[cursive-ghost]

It also depends on how you're running your project. If you're using lein, then the version of nREPL is the one that lein uses. But coincidentally, recent versions of Clojure also started using recent versions of Leiningen (mostly because of all the churn in the tooling world because of the nREPL split), and since the most recent version of lein is the one used by default, a side effect of upgrading Cursive will also be upgrading nREPL.
