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