 - Add macros `before-each` and `after-each`, which are run before/after each nested test case.
 
+- Add function `set-ns-context!` which sets the current namespace's context to be the given vector. Works like `clojure.test/use-fixture`.

 ### Changes
 
 - Changed primary branch from `master` to `main`.

-Context functions of the same kind are run in the order they're defined. When executing a given suite or test-case, all `(before)` hooks are run once, then each `before-each` hook is run, then the `(around)` hooks are called on the nested tests (if they exist), then each `(after-each)` hook is run, then all `(after)` hooks are run once.
