28 # usage: vg_regtest [options] <dirs | files>
31 # --all: run tests in all subdirs
32 # --valgrind: valgrind launcher to use. Default is ./coregrind/valgrind.
33 # (This option should probably only be used in conjunction with
35 # --valgrind-lib: valgrind libraries to use. Default is $tests_dir/.in_place.
36 # (This option should probably only be used in conjunction with
38 # --keep-unfiltered: keep a copy of the unfiltered output/error output
39 # of each test by adding an extension .unfiltered.out
41 # --outer-valgrind: run this valgrind under the given outer valgrind.
42 # This valgrind must be configured with --enable-inner.
43 # --outer-tool: tool to use by the outer valgrind (default memcheck).
44 # --outer-args: use this as outer tool args. If the outer args are starting
45 # with +, the given outer args are appended to the outer args predefined
47 # --loop-till-fail: loops on the test(s) till one fail, then exit
48 # This is useful to obtain detailed trace or --keep-unfiltered
49 # output of a non deterministic test failure
51 # The easiest way is to run all tests in valgrind/ with (assuming you installed
54 # $PREFIX/bin/vg_regtest --all
56 # You can specify individual files to test, or whole directories, or both.
57 # Directories are traversed recursively, except for ones named, for example,
60 # Each test is defined in a file <test>.vgtest, containing one or more of the
61 # following lines, in any order:
62 # - prog: <prog to run>
63 # - prog-asis: <prog to run>
64 # - env: <environment variable for prog> (default: none)
65 # - args: <args for prog> (default: none)
66 # - vgopts: <Valgrind options> (default: none;
67 # multiple are allowed)
68 # - stdout_filter: <filter to run stdout through> (default: none)
69 # - stderr_filter: <filter to run stderr through> (default: ./filter_stderr)
70 # - stdout_filter_args: <args for stdout_filter> (default: basename of .vgtest file)
71 # - stderr_filter_args: <args for stderr_filter> (default: basename of .vgtest file)
73 # - progB: <prog to run in parallel with prog> (default: none)
74 # - envB: <environment variable for progB> (default: none)
75 # - argsB: <args for progB> (default: none)
76 # - stdinB: <input file for progB> (default: none)
77 # - stdoutB_filter: <filter progB stdout through> (default: none)
78 # - stderrB_filter: <filter progB stderr through> (default: ./filter_stderr)
79 # - stdoutB_filter_args: <args for stdout_filterB> (default: basename of .vgtest file)
80 # - stderrB_filter_args: <args for stderr_filterB> (default: basename of .vgtest file)
82 # - prereq: <prerequisite command> (default: none)
83 # - post: <post-test check command> (default: none)
84 # - cleanup: <post-test cleanup cmd> (default: none)
86 # One of prog or prog-asis must be specified.
87 # If prog or probB is a relative path, it will be prefix with the test directory.
88 # prog-asis will be taken as is, i.e. not prefixed with the test directory.
89 # Note that filters are necessary for stderr results to filter out things that
90 # always change, eg. process id numbers.
91 # Note that if a progB is specified, it is started in background (before prog).
93 # There can be more than one env: declaration. Here is an example:
94 # env: PATH=/opt/bin:$PATH
97 # Expected stdout (filtered) is kept in <test>.stdout.exp* (can be more
98 # than one expected output). It can be missing if it would be empty. Expected
99 # stderr (filtered) is kept in <test>.stderr.exp*. There must be at least
100 # one stderr.exp* file. Any .exp* file that ends in '~' or '#' is ignored;
101 # this is because Emacs creates temporary files of these names.
103 # Expected output for progB is handled similarly, except that
104 # expected stdout and stderr for progB are in <test>.stdoutB.exp*
105 # and <test>.stderrB.exp*.
107 # If results don't match, the output can be found in <test>.std<strm>.out,
108 # and the diff between expected and actual in <test>.std<strm>.diff*.
109 # (for progB, in <test>.std<strm>2.out and <test>.std<strm>2.diff*).
111 # The prerequisite command, if present, works like this:
112 # - if it returns 0 the test is run
113 # - if it returns 1 the test is skipped
114 # - if it returns anything else the script aborts.
115 # The idea here is results other than 0 or 1 are likely to be due to
116 # problems with the commands, and you don't want to conflate them with the 1
117 # case, which would happen if you just tested for zero or non-zero.
119 # The post-test command, if present, must return 0 and its stdout must match
120 # the expected stdout which is kept in <test>.post.exp*.
122 # Sometimes it is useful to run all the tests at a high sanity check
123 # level or with arbitrary other flags. To make this simple, extra
124 # options, applied to all tests run, are read from $EXTRA_REGTEST_OPTS,
125 # and handed to valgrind prior to any other flags specified by the
128 # Some more notes on adding regression tests for a new tool are in
129 # docs/xml/manual-writing-tools.xml.
