comparison scripts/runtest.sh @ 1485:8700cbe1cb29 draft

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Move testsuite out of scripts/test into its own top level tests directory, and make ctrl-c kill "make test" more reliably.

5 # This file defines two functions, "testing" and "optionflag"
6
7 # The following environment variables enable optional behavior in "testing":
8 # DEBUG - Show every command run by test script.
9 # VERBOSE - Print the diff -u of each failed test case.
10 # If equal to "fail", stop after first failed test.
11 # SKIP - do not perform this test (this is set by "optionflag")
12 #
13 # The "testing" function takes five arguments:
14 # $1) Description to display when running command
15 # $2) Command line arguments to command
16 # $3) Expected result (on stdout)
17 # $4) Data written to file "input"
18 # $5) Data written to stdin
19 #
20 # The exit value of testing is the exit value of the command it ran.
21 #
22 # The environment variable "FAILCOUNT" contains a cumulative total of the
23 # number of failed tests.
24
25 # The "optional" function is used to skip certain tests, ala:
26 # optionflag CFG_THINGY
27 #
28 # The "optional" function checks the environment variable "OPTIONFLAGS",
29 # which is either empty (in which case it always clears SKIP) or
30 # else contains a colon-separated list of features (in which case the function
31 # clears SKIP if the flag was found, or sets it to 1 if the flag was not found).

34 export SKIP=

36 # Helper functions

38 # Check config to see if option is enabled, set SKIP if not.
