4 For a developer, the simplest way of running most tests on a local
5 machine from within the git repository is:
9 This runs all unit tests (onnode, takeover, tool, eventscripts) and
10 the tests against local daemons (simple) using the script
13 When running tests against a real or virtual cluster the script
14 tests/run_cluster_tests.sh can be used. This runs all integration
15 tests (simple, complex).
17 Both of these scripts can also take a list of tests to run. You can
18 also pass options, which are then passed to run_tests. However, if
19 you just try to pass options to run_tests then you lose the default
20 list of tests that are run. You can't have everything...
25 This script can be used to manually run all or selected unit tests and
26 simple integration tests against local daemons. Test selection is done
27 by specifying optional call parameters. If no parameter is given,
28 all unit tests and simple integration tests are run.
30 This runs all unit tests of the "tool" category:
32 ./tests/run_tests.sh tool
34 In order to run a single test, one simply specifies the path of the
35 test script to run as the last parameter, e.g.:
37 ./tests/run_tests.sh ./tests/eventscripts/00.ctdb.monitor.001
38 ./tests/run_tests.sh ./tests/simple/76_ctdb_pdb_recovery.sh
40 One can also specify multiple test suites and tests:
42 ./tests/run_tests.sh eventscripts tool ./tests/onnode/0001.sh
44 The script also has number of command-line switches.
45 Some of the more useful options include:
47 -s Print a summary of tests results after running all tests
49 -l Use local daemons for integration tests
51 This allows the tests in "simple" to be run against local
54 All integration tests communicate with cluster nodes using
55 onnode or the ctdb tool, which both have some test hooks to
56 support local daemons.
58 By default 3 daemons are used. If you want to use a different
59 number of daemons then do not use this option but set
60 TEST_LOCAL_DAEMONS to the desired number of daemons instead.
61 The -l option just sets TEST_LOCAL_DAEMONS to 3... :-)
63 -e Exit on the first test failure
65 -C Clean up - kill daemons and remove $TEST_VAR_DIR when done
67 Tests uses a temporary/var directory for test state. By default,
68 this directory is not removed when tests are complete, so you
69 can do forensics or, for integration tests, re-run tests that
70 have failed against the same directory (with the same local
71 daemons setup). So this option cleans things up.
73 Also kills local daemons associated with directory.
75 -V Use <dir> as $TEST_VAR_DIR
77 Use the specified temporary temporary/var directory.
79 -H No headers - for running single test with other wrapper
81 This allows tests to be embedded in some other test framework
82 and executed one-by-one with all the required
83 environment/infrastructure.
85 This replaces the old ctdb_test_env script.
87 How do the tests find remote test programs?
88 -------------------------------------------
90 If the all of the cluster nodes have the CTDB git tree in the same
91 location as on the test client then no special action is necessary.
92 The simplest way of doing this is to share the tree to cluster nodes
93 and test clients via NFS.
95 If cluster nodes do not have the CTDB git tree then
96 CTDB_TEST_REMOTE_DIR can be set to a directory that, on each cluster
97 node, contains the contents of tests/scripts/ and tests/bin/.
99 In the future this will hopefully (also) be supported via a ctdb-test
102 Running the ctdb tool under valgrind
103 ------------------------------------
105 The easiest way of doing this is something like:
107 VALGRIND="valgrind -q" scripts/run_tests ...
109 This can be used to cause all invocations of the ctdb client (and,
110 with local daemons, the ctdbd daemons themselves) to occur under
113 NOTE: Some libc calls seem to do weird things and perhaps cause
114 spurious output from ctdbd at start time. Please read valgrind output
115 carefully before reporting bugs. :-)
117 How is the ctdb tool invoked?
118 -----------------------------
120 $CTDB determines how to invoke the ctdb client. If not already set
121 and if $VALGRIND is set, this is set to "$VALGRIND ctdb". If this is
122 not already set but $VALGRIND is not set, this is simply set to "ctdb"
