+# 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

+# - events_waits_summary_by_user_by_event_name

+# - events_waits_summary_global_by_event_name
+# - events_stages_summary_global_by_event_name
+# - events_statements_summary_global_by_event_name

+# The tests are written with the following helpers:
+# - include/event_aggregate_setup.inc
+# - include/event_aggregate_load.inc
+# - include/event_aggregate_cleanup.inc
+#
+# Helpers are intended to be used as follows.
+#
+# A Typical test t/event_aggregate_xxx.test will consist of:
+# --source ../include/event_aggregate_setup.inc
+# --source ../include/event_aggregate_load.inc
+# --source ../include/event_aggregate_cleanup.inc
+# and a t/event_aggregate_xxx-master.opt file
+#
+# Naming conventions for t/event_aggregate_xxx.test are as follows:
+# t/event_aggregate_<account><user><host>
+#
+# <account> corresponds to different sizing settings for 
+# the variable performance-schema-accounts-size
+# - (blank): accounts-size sufficient to represent all records
+# - 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
+# - 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

+# Purpose
+#    Various checks for the content of the table socket_summary_by_instance.
+#
+# It is intentional that we do not try to cram as much checks as possible into
+# one single SQL statement.
+# Reasons:
+# - We check performance_schema here and NOT something like optimizer.
+# - This test should work even if some other feature has become buggy.
+# - In case some check gives unexpected results than we print the
+#   relevant content of the table and the values which we expect.
+#   In case of all checks in one statement such a printout would be too huge.
+#
+# IMPORTANT:
+#   The maximum number of rows which the table socket_summary_by_instance
+#   can keep is limited via the system variables max_socket_classes and
+#   max_socket_instances.  We are running with the default values here.
+#   They are sufficient high so that these limits cannot harm the current test.

+# Tests for the performance schema
+
+# =============
+# DOCUMENTATION
+# =============
+
+# Verify how table io is aggregated into various tables
+#
+# In the instance dimension:
+# - table_io_waits_summary_by_index_usage
+# - table_io_waits_summary_by_table
+# - table_lock_waits_summary_by_table
+# - objects_summary_global_by_type
+#
+# In the thread dimension:
+# - events_waits_summary_by_thread_by_event_name
+# - events_waits_summary_by_account_by_event_name
+# - events_waits_summary_by_user_by_event_name
+# - events_waits_summary_by_host_by_event_name
+#
+# Globally:
+# - events_waits_summary_global_by_event_name
+#
+# The tests are written with the following helpers:
+# - include/table_aggregate_setup.inc
+# - include/table_aggregate_load.inc
+# - include/table_aggregate_cleanup.inc
+#
+# Helpers are intended to be used as follows.
+#
+# A Typical test t/table_aggregate_xxx.test will consist of:
+# --source ../include/table_aggregate_setup.inc
+# 
+# ... statements to modify the default configuration ...
+#
+# --source ../include/table_aggregate_load.inc
+# --source ../include/table_aggregate_cleanup.inc
+#
+# Naming conventions for t/table_aggregate_xxx.test are as follows:
+# t/<instrument>aggregate_<mode><actors><objects>
+#
+# <instrument> corresponds to different instruments settings
+# - table: both table io and table lock are instrumented
+# - table_io: only table io is instrumented
+# - table_lock: only table lock is instrumented
+#
+# <mode> corresponds to different consumers settings
+# - off: global_instrumentation OFF
+# - global: global_instrumentation ON, thread_instrumentation OFF
+# - thread: global_instrumentation ON, thread_instrumentation ON,
+#           events_* consumers OFF
+# - history: global_instrumentation ON, thread_instrumentation ON,
+#           events_* consumers ON
+#
+# <actors> corresponds to different setup_actors settings
+# - 4u: every test user (user1, user2, user3, user4) is ON
+# - 2u: (user1, user3) are ON, (user2, user4) are OFF
+#
+# <objects> corresponds to different setup_objects settings
+# - 3t: tables t1, t2 and t3 are ON
+# - 2t: tables t1 and t3 are ON, table t2 is OFF
