Description

When looking at (log) output from tests written with clojure.test, I would like to be able to identify the output associated with each test. A mechanism to expose the current test var within an :each fixture would enable this.

One mechanism might be to bind a test-var var with the current test var before calling the each-fixture-fn in clojure.test/test-all-vars.

Or just pass the Var directly into the fixture. Vars are invokable.

I don't think that works, since the the function passed to the fixture is not the test var, but a function calling test-var on the test var.

*testing-vars* already has this information, but it's not visible to the fixture functions because it gets bound inside test-var.

Perhaps the :each fixture functions should be called in test-var rather than in test-all-vars. (The namespace of a Var is available in its metadata.) But then we have to call join-fixtures inside test-var every time.

Try this patch: clj840-2.diff.

This makes *testing-vars* visible to :each fixture functions, which seems intuitively more correct.

BUT it slightly changes the behavior of test-var, which I'm less happy about.

Might it make sense to provide a function on top of testing-vars to return the current test-var?

No, that function is first

I agree with having the dynamic vars as part of the extension interface, but would have thought that having a function for use when writing tests would have been cleaner. Just my 2c.
