We use grep -o here to filter output, but that's not available on OpenIndiana. It does offer "ggrep" though, which is GNU grep.

# Test that the invocation of the fish executable works as we hope.
|
|
#
|
|
# We try to run the 'fish' binary with different command line switches.
|
|
# Each time we check against an output that we expect.
|
|
#
|
|
# We are testing fish's invocation itself, so this is not written in
|
|
# fish itself - if the invocation wasn't working, we'd never even
|
|
# be able to use this test to check that the invocation wasn't working.
|
|
#
|
|
# What we test...
|
|
#
|
|
# * The environment is cleaned so that (hopefully) differences in
|
|
# the host terminal, language or user settings do not affect the
|
|
# tests.
|
|
#
|
|
# * The files 'tests/invocation/*.invoke' contain the arguments that
|
|
# will be passed to the 'fish' command under test. The arguments
|
|
# may be split over multiple lines for clarity.
|
|
#
|
|
# * Before execution, if the file 'tests/invocation/<name>.config'
|
|
# exists, it will be copied as the 'config.fish' file in the
|
|
# configuration directory.
|
|
#
|
|
# * The stdout and stderr are captured into files and will be
|
|
# processed before comparison with the
|
|
# 'tests/invocation/<name>.(out|err)' files. A missing file is
|
|
# considered to be no output.
|
|
# Either file may be given a further suffix of '.<system name>'
|
|
# which will be used in preference to the default. This allows
|
|
# the expected output to change depending on the system being
|
|
# used - to allow for differences in behaviour.
|
|
# The '<system name>' can be found with 'uname -s'.
|
|
# This facility should be used sparingly as system differences
|
|
# will confuse users.
|
|
#
|
|
# * The file 'tests/invocation/<name>.grep' is used to select the
|
|
# sections of the file we are interested in within the stdout.
|
|
# Only the parts that match will be compared to the '*.out' file.
|
|
# This can be used to filter out changeable parts of the output
|
|
# leaving just the parts we are interested in.
|
|
#
|
|
# * The stderr output will have the 'RC: <return code>' appended
|
|
# if the command returned a non-zero value.
|
|
# The stderr output will have the 'XDG_CONFIG_HOME' location
|
|
# substituted, to allow error reports to be compared consistently.
|
|
#
|
|
# * If the processed output differs from the supplied output,
|
|
# the test will fail, and the differences will be shown on the
|
|
# console.
|
|
#
|
|
# * If anything fails, the return code for this script will be
|
|
# non-zero.
|
|
#
|
|
|
|
# With this, errors would be fatal.
|
|
# However, a return value of non-zero doesn't signal something that necessarily should be fatal.
|
|
# For instance, `tput` returns 1 if an attribute isn't defined.
|
|
# But we don't want it to kill our script, especially not without any indication.
