on discouraged to use it.

 Asserts that the function `block` does not throw an error. See
 [`assert.throws()`][] for more details.
 
+Please note: Using `assert.doesNotThrow()` is actually not useful because there
+is no benefit by catching an error and then rethrowing it. Instead, consider
+adding a comment next to the specific code path that should not throw and keep
+error messages as expressive as possible.

 When `assert.doesNotThrow()` is called, it will immediately call the `block`
 function.
