7 # This file defines two functions, "testing" and "optional"
10 # The following environment variables may be set to enable optional behavior
12 # VERBOSE - Print the diff -u of each failed test case.
13 # DEBUG - Enable command tracing.
14 # SKIP - do not perform this test (this is set by "optional")
16 # The "testing" function takes five arguments:
17 # $1) Test description
18 # $2) Command(s) to run. May have pipes, redirects, etc
19 # $3) Expected result on stdout
20 # $4) Data to be written to file "input"
21 # $5) Data to be written to stdin
23 # The exit value of testing is the exit value of $2 it ran.
25 # The environment variable "FAILCOUNT" contains a cumulative total of the
26 # number of failed tests.
28 # The "optional" function is used to skip certain tests, ala:
29 # optional CONFIG_FEATURE_THINGY
31 # The "optional" function checks the environment variable "OPTIONFLAGS",
32 # which is either empty (in which case it always clears SKIP) or
33 # else contains a colon-separated list of features (in which case the function
34 # clears SKIP if the flag was found, or sets it to 1 if the flag was not found).
