-## This module implements the standard unit testing facilities such as
-## suites, fixtures and test cases as well as facilities for combinatorial 
-## and randomzied test case generation (not yet available) 
-## and object mocking (not yet available)
+## This module implements boilerplate to make testing easy.
 ##
-## It is loosely based on C++'s boost.test and Haskell's QuickTest
+## Example:
+##
+## .. code:: nim
+##
+##   suite "description for this stuff":
+##     test "essential truths":
+##       # give up and stop if this fails
+##       require(true)
+##
+##     test "slightly less obvious stuff":
+##       # print a nasty message and move on, skipping
+##       # the remainder of this block
+##       check(1 != 1)
+##       check("asd"[2] == 'd')
+##
+##     test "out of bounds error is thrown on bad access":
+##       let v = @[1, 2, 3]  # you can do initialization here
+##       expect(IndexError):
+##         discard v[4]
