This directory is for regression test programs.
|
|
|
|
A regression test program is one that will exercise a particular bit of the
|
|
system to check that we have not reintroduced an old bug.
|
|
|
|
Tests should be implemented in files with a .t extension. Each .t file
|
|
can contain more than one test, and can be implemented in any scripting
|
|
language -- /bin/sh, Perl...
|
|
|
|
The test protocol is quite simple. At its most basic, each .t file should,
|
|
when run, print a line in this format:
|
|
|
|
1..m
|
|
|
|
where m is the number of tests that will be run.
|
|
|
|
Each test should produce a single line of output. This line should start
|
|
with one of
|
|
|
|
ok n
|
|
not ok n
|
|
|
|
to indicate whether or not the test succeeded. 'n' is the test's number.
|
|
Anything after this on the line (up to the first '#' if present) is
|
|
considered to be the name of the test. Naming tests is optional, but
|
|
encouraged.
|
|
|
|
A test may be written which is conditional, and may need to be skipped.
|
|
For example, the netatalk tests require 'options NETATALK' in the kernel.
|
|
A test may be skipped by printing '# skip Reason for skipping' after the
|
|
test name. For example,
|
|
|
|
ok 1 - netatalk # skip 'options NETATALK' not compiled in
|
|
|
|
A test may be flagged as 'todo'. This indicates that you expect the test
|
|
to fail (perhaps because the necessary functionality hasn't been written
|
|
yet). 'todo' tests are expected to fail, so when they start working the
|
|
test framework can alert you to this happy occurence. Flag these tests
|
|
with a '# TODO' comment after the test name
|
|
|
|
not ok 1 - infiniteloop # TODO write test for an infinite loop
|
|
|
|
This is modelled on the protocol followed by the Test::Harness Perl
|
|
module (and therefore much of the automated testing carried out by the
|
|
Perl community). More documentation can be found at:
|
|
|
|
http://search.cpan.org/~petdance/Test-Harness-2.42/lib/Test/Harness.pm
|
|
|
|
To run the tests and parse their output install the devel/p5-Test-Harness
|
|
port. This includes the prove(1) command which is used to run the tests
|
|
and collate the output.
|
|
|
|
prove geom_concat # run all the tests in geom_concat
|
|
prove -r lib # run all tests in lib/, and subdirectories
|
|
prove -r -v lib # as above, with verbose output
|
|
prove -r # run *all* the tests
|
|
|
|
Tests that are for parts of the base system should go into a directory here
|
|
which is the same as their path relative to src/, for example the uuencode(1)
|
|
utility resides in src/usr.bin/uuencode so its regression test resides in
|
|
src/tools/regression/usr.bin/uuencode.
|
|
|
|
To avoid the pre-commit check program complaining about the lack of
|
|
CVS keywords in test data files, use a .in suffix for input files and
|
|
a .out suffix for output files.
|
|
|
|
To execute individual regression tests for binaries that you are
|
|
developing, add their directory in the path before running the tests.
|
|
Example:
|
|
cd /usr/src/tools/regression/usr.bin
|
|
(PATH=/home/user/src/experimental/jot:$PATH ; make SUBDIR=jot)
|
|
|
|
Please make a subdir per other regression test, and add a brief description to
|
|
this file.
