# Utility for testing the web server. Test cases:
# Assume the device supports 'n' simultaneous open sockets
#
# HTTP Server Tests
#
# 0. Firmware Settings:
# - Create a dormant thread whose sole job is to call httpd_stop() when instructed
# - Measure the following before httpd_start() is called:
# - current free memory
# - current free sockets
# - Measure the same whenever httpd_stop is called
# - Register maximum possible URI handlers: should be successful
# - Register one more URI handler: should fail
# - Deregister on URI handler: should be successful
# - Register on more URI handler: should succeed
# - Register separate handlers for /hello, /hello/type_html. Also
# ensure that /hello/type_html is registered BEFORE /hello. (tests
# that largest matching URI is picked properly)
# - Create URI handler /adder. Make sure it uses a custom free_ctx
# structure to free it up
# 1. Using Standard Python HTTP Client
# - simple GET on /hello (returns Hello World. Ensures that basic
# firmware tests are complete, or returns error)
# - POST on /hello (should fail)
# - PUT on /hello (should fail)
# - simple POST on /echo (returns whatever the POST data)
# - simple PUT on /echo (returns whatever the PUT data)
# - GET on /echo (should fail)
# - simple GET on /hello/type_html (returns Content type as text/html)
# - simple GET on /hello/status_500 (returns HTTP status 500)
# - simple GET on /false_uri (returns HTTP status 404)
# - largest matching URI handler is picked is already verified because
# of /hello and /hello/type_html tests
#
#
# 2. Session Tests
# - Sessions + Pipelining basics:
# - Create max supported sessions
# - On session i,
# - send 3 back-to-back POST requests with data i on /adder
# - read back 3 responses. They should be i, 2i and 3i
# - Tests that
# - pipelining works
# - per-session context is maintained for all supported
# sessions
# - Close all sessions
#
# - Cleanup leftover data: Tests that the web server properly cleans
# up leftover data
# - Create a session
# - POST on /leftover_data with 52 bytes of data (data includes
# \r\n)(the handler only
# reads first 10 bytes and returns them, leaving the rest of the
# bytes unread)
# - GET on /hello (should return 'Hello World')
# - POST on /false_uri with 52 bytes of data (data includes \r\n)
# (should return HTTP 404)
# - GET on /hello (should return 'Hello World')
#
# - Test HTTPd Asynchronous response
# - Create a session
# - GET on /async_data
# - returns 'Hello World!' as a response
# - the handler schedules an async response, which generates a second
# response 'Hello Double World!'
#
# - Spillover test
# - Create max supported sessions with the web server
# - GET /hello on all the sessions (should return Hello World)
# - Create one more session, this should fail
# - GET /hello on all the sessions (should return Hello World)
#
# - Timeout test
# - Create a session and only Send 'GE' on the same (simulates a
# client that left the network halfway through a request)
# - Wait for recv-wait-timeout
# - Server should automatically close the socket
# ############ TODO TESTS #############
# 3. Stress Tests
#
# - httperf
# - Run the following httperf command:
# httperf --server=10.31.130.126 --wsess=8,50,0.5 --rate 8 --burst-length 2
#
# - The above implies that the test suite will open
# - 8 simultaneous connections with the server
# - the rate of opening the sessions will be 8 per sec. So in our
# case, a new connection will be opened every 0.2 seconds for 1 second
# - The burst length 2 indicates that 2 requests will be sent
# simultaneously on the same connection in a single go
# - 0.5 seconds is the time between sending out 2 bursts
# - 50 is the total number of requests that will be sent out
#
# - So in the above example, the test suite will open 8
# connections, each separated by 0.2 seconds. On each connection
# it will send 2 requests in a single burst. The bursts on a
# single connection will be separated by 0.5 seconds. A total of
# 25 bursts (25 x 2 = 50) will be sent out
# 4. Leak Tests
# - Simple Leak test
# - Simple GET on /hello/restart (returns success, stop web server, measures leaks, restarts webserver)
# - Simple GET on /hello/restart_results (returns the leak results)
# - Leak test with open sockets
# - Open 8 sessions
# - Simple GET on /hello/restart (returns success, stop web server,
# measures leaks, restarts webserver)
# - All sockets should get closed
# - Simple GET on /hello/restart_results (returns the leak results)
