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