+2htdp comes with three different kinds of tests: 
+
+1. tests 
+   This directory contains end-to-end tests for big-bang and universe.
+
+   These tests are mostly automatic except for two of them which expect 
+   some interaction (move mouse, hold key). 
+   
+   The expected output is mostly some sign that the test is 'done' or 
+   that no random tests failed or some cpu time. Failures are indicated
+   with the word failure. 
+
+   To execute these tests, run 
+
+      $ ./xtest in this directory 
+
+2. utest, uchat
+   These two directories contain end-to-end universe program tests. 
+
+   To execute these tests, run 
+   
+     $ ./xrun in the respective directory 
+
+   In utest, xrun pops up two world screens that show a ball moving in one
+   of two canvases. Kill one world after another, then stop the universe. 
+   (It may also pop up additional world state and universe state screens.) 
+
+   In uchat, xrun pops up two chat room screens. Type in one, see the text
+   appear in the other when you hit return. 
+
+3. tests-failed 
+   This directory contains tests that are currently expected to fail. 
+
+
