1# $FreeBSD$ 2 3The files in this directory with suffixes `.t', `.d', `.r' and `.err' are 4used for testing ed. To run the tests, set the ED variable in the Makefile 5for the path name of the program to be tested (e.g., /bin/ed), and type 6`make'. The tests do not exhaustively verify POSIX compliance nor do 7they verify correct 8-bit or long line support. 8 9The test file suffixes have the following meanings: 10.t Template - a list of ed commands from which an ed script is 11 constructed 12.d Data - read by an ed script 13.r Result - the expected output after processing data via an ed 14 script. 15.err Error - invalid ed commands that should generate an error 16 17The output of the tests is written to the two files err.o and scripts.o. 18At the end of the tests, these files are grep'ed for error messages, 19which look like: 20 *** The script u.ed exited abnormally *** 21or: 22 *** Output u.o of script u.ed is incorrect *** 23 24The POSIX requirement that an address range not be used where at most 25a single address is expected has been relaxed in this version of ed. 26Therefore, the following scripts which test for compliance with this 27POSIX rule exit abnormally: 28=-err.ed 29a1-err.ed 30i1-err.ed 31k1-err.ed 32r1-err.ed 33
