# This file defines two functions, "testing" and "optionflag"
|
|
|
|
# The following environment variables may be set to enable optional behavior
|
|
# in "testing":
|
|
# VERBOSE - Print the diff -u of each failed test case.
|
|
# DEBUG - Enable command tracing.
|
|
# SKIP - do not perform this test (this is set by "optionflag")
|
|
#
|
|
# The "testing" function takes five arguments:
|
|
# $1) Description to display when running command
|
|
# $2) Command line arguments to command
|
|
# $3) Expected result (on stdout)
|
|
# $4) Data written to file "input"
|
|
# $5) Data written to stdin
|
|
#
|
|
# The exit value of testing is the exit value of the command it ran.
|
|
#
|
|
# The environment variable "FAILCOUNT" contains a cumulative total of the
|
|
# number of failed tests.
|
|
|
|
# The "optional" function is used to skip certain tests, ala:
|
|
# optionflag CONFIG_FEATURE_THINGY
|
|
#
|
|
# The "optional" function checks the environment variable "OPTIONFLAGS",
|
|
# which is either empty (in which case it always clears SKIP) or
|
|
# else contains a colon-separated list of features (in which case the function
|
|
# clears SKIP if the flag was found, or sets it to 1 if the flag was not found).
