Tears down something previously set up in a test fixture.

Takes a lock name (matching the one used in initialize!) and a body to execute. The body will execute once to clean up resources. Locks the initializer block from running while deinitializing, ensuring thread-safe cleanup in multi-threaded test runners.

Example:

(defn printer-fixture [f]
  (initialize! ::print-job
    (prn "Good Job"))
  (f)
  (deinitialize! ::print-job
    (prn "We deinitialized")))

Implements intialize!/de-initialize! macro

Sets up something in a test fixture that runs once and won’t run again until deinitialized.

Handles multi-threaded test runners by using locks to ensure exclusive execution. Takes a lock name (typically a namespaced keyword) and a body to execute. The body will only execute once per lock name across all parallel test threads, even if the fixture is called multiple times.

Example:

(defn printer-fixture [f]
  (initialize! ::print-job
    (prn "Good Job"))
  (f))

Resets all locks created by the wrap macro.
