Answer: it’s painful… https://github.com/jaycfields/expectations/issues/70#issuecomment-237113313

I love how terse Expectations is but the lack of fixed symbol names causes all sorts of problems that the other test libraries just don’t have. In addition, Expectations does a fair bit of "magic" for its fixtures support (it loads a fixed namespace automatically behind the scenes) and when it does a test run — over one or more namespaces — it also does a fair bit of setup and teardown which makes it even harder to shoehorn into the model of pulling a bunch of :test metadata and just running functions...

I’ll probably have another run at it, but maybe not until next week (perhaps after I’ve gotten some feedback from folks on that ticket).

WARNING: CIDER's version (0.14.0-snapshot) does not match cider-nrepl's version (nil). Things will break!

I have [cider/cider-nrepl "0.14.0-SNAPSHOT”] in the plugin deps list.

is this warning caused by string mismatch ? does it affect usage ?

@yusup, I was encountering this error in Spacemacs and updating the CIDER package seems to have fixed that for me.
