+# Tests for the performance schema
+
+# =============
+# DOCUMENTATION
+# =============
+
+# Verify how connections are counted into various tables:
+# - accounts
+# - users
+# - hosts
+#
+# The tests are written with the following helpers:
+# - include/connection_setup.inc
+# - include/connection_load.inc
+# - include/connection_cleanup.inc
+#
+# Helpers are intended to be used as follows.
+#
+# A Typical test t/connection_xxx.test will consist of:
+# --source ../include/connection_setup.inc
+# --source ../include/connection_load.inc
+# --source ../include/connection_cleanup.inc
+# and a t/connection_xxx-master.opt file
+#
+# Naming conventions for t/connection_xxx.test are as follows:
+# t/connection_<account><user><host>
+#
+# <account> corresponds to different sizing settings for 
+# the variable performance-schema-accounts-size
+# - (blank): accounts-size sufficient to represent all records
+# - 3a: accounts-size set to 3
+# - no_a: accounts-size set to 0
+#
+# <user> corresponds to different sizing settings for 
+# the variable performance-schema-users-size
+# - (blank): users-size sufficient to represent all records
+# - 3u: users-size set to 3
+# - no_u: users-size set to 0
+#
+# <host> corresponds to different sizing settings for 
+# the variable performance-schema-hosts-size
+# - (blank): hosts-size sufficient to represent all records
+# - no_h: hosts-size set to 0
