In Cider, I can use
C-c , to run the tests for the current namespace. This will work whether I'm currently in the source namespace or the test namespace itself (and indeed, this magic behavior is discussed in detail in the README).
Given that Cider already knows how to find the test namespace for a given source namespace (and I'd assume that finding the reverse is a similar problem), is there a function that I can use to quickly switch from a source buffer (e.g.
src/example/core.clj) to its test buffer (e.g.
test/example/core_test.clj) and vice versa?
