>>ASSERTION Good A
When a client sends a valid xname protocol request to the X server,
then the X server does not send back an error, event or reply to the client.
>>STRATEGY
Call library function testfunc() to do the following:
Open a connection to the X server using native byte sex.
Send a valid xname protocol request to the X server.
Verify that the X server does not send back an error, event or reply.
Open a connection to the X server using reversed byte sex.
Send a valid xname protocol request to the X server.
Verify that the X server does not send back an error, event or reply.
>>CODE

	test_type = GOOD;

	/* Call a library function to exercise the test code */
	testfunc(tester);

>>ASSERTION Bad A
When a client sends an invalid xname protocol request to the X server,
in which the length field of the request is not the minimum length required to 
contain the request,
then the X server sends back a BadLength error to the client.
>>STRATEGY
Call library function testfunc() to do the following:
Open a connection to the X server using native byte sex.
Send an invalid xname protocol request to the X server with length 
  one less than the minimum length required to contain the request.
Verify that the X server sends back a BadLength error.
Open a connection to the X server using reversed byte sex.
Send an invalid xname protocol request to the X server with length 
  one less than the minimum length required to contain the request.
Verify that the X server sends back a BadLength error.

Open a connection to the X server using native byte sex.
Send an invalid xname protocol request to the X server with length 
  one greater than the minimum length required to contain the request.
Verify that the X server sends back a BadLength error.
Open a connection to the X server using reversed byte sex.
Send an invalid xname protocol request to the X server with length 
  one greater than the minimum length required to contain the request.
Verify that the X server sends back a BadLength error.
>>CODE

	test_type = BAD_LENGTH; /* < minimum */

	/* Call a library function to exercise the test code */

>>ASSERTION Bad B 1
When a client sends an invalid xname protocol request to the X server,
in which the length field of the request exceeds the maximum length accepted
by the X server,
then the X server sends back a BadLength error to the client.
>>STRATEGY
Call library function testfunc() to do the following:
Open a connection to the X server using native byte sex.
Send an invalid xname protocol request to the X server with length 
  one greater than the maximum length accepted by the server.
Verify that the X server sends back a BadLength error.
Open a connection to the X server using reversed byte sex.
Send an invalid xname protocol request to the X server with length 
  one greater than the maximum length accepted by the server.
Verify that the X server sends back a BadLength error.
