Introduction ------------ For a developer, the simplest way of running most tests on a local machine from within the git repository is: make test This runs all UNIT and INTEGRATION tests. tests/run_tests.sh ------------------ This script can be used to manually run all tests or selected tests, with a variety of options. For usage, run: tests/run_tests.sh -h If no tests are specified this runs all of the UNIT and INTEGRATION tests. By default: * INTEGRATION tests are run against 3 local daemons * When testing is complete, a summary showing a list is printed showing the tests run and their results Tests can be selected in various ways: * tests/run_tests.sh UNIT INTEGRATION runs all UNIT and INTEGRATION tests, and is like specifying no tests * tests/run_tests.sh UNIT/tool runs all of the "tool" UNIT tests * tests/run_tests.sh tests/UNIT/eventscripts/00.ctdb.setup.001.sh tests/run_tests.sh tests/INTEGRATION/simple/basics.001.listnodes.sh each runs a single specified test case * tests/run_tests.sh UNIT/eventscripts UNIT/tool tests/UNIT/onnode/0001.sh runs a combination of UNIT test suites and a single UNIT test Testing on a cluster -------------------- INTEGRATION and CLUSTER tests can be run on a real or virtual cluster using tests/run_cluster_tests.sh (or "tests/run_tests.sh -c"). The test code needs to be available on all cluster nodes, as well as the test client node. The test client node needs to have a nodes file where the onnode(1) command will find it. If the all of the cluster nodes have the CTDB git tree in the same location as on the test client then no special action is necessary. The simplest way of doing this is to share the tree to cluster nodes and test clients via NFS. Alternatively, the tests can be installed on all nodes. One technique is to build a package containing the tests and install it on all nodes. CTDB developers do a lot of testing this way using the provided sample packaging, which produces a ctdb-tests RPM package. Finally, if the test code is installed in a different place on the cluster nodes, then CTDB_TEST_REMOTE_DIR can be set on the test client node to point to a directory that contains the test_wrap script on the cluster nodes. Running tests under valgrind ---------------------------- The easiest way of doing this is something like: VALGRIND="valgrind -q" tests/run_tests ... This can be used to cause all invocations of the ctdb tool, test programs and, with local daemons, the ctdbd daemons themselves to run under valgrind. How is the ctdb tool invoked? ----------------------------- $CTDB determines how to invoke the ctdb client. If not already set and if $VALGRIND is set, this is set to "$VALGRIND ctdb". If this is not already set but $VALGRIND is not set, this is simply set to "ctdb" Test and debugging variable options ----------------------------------- CTDB_TEST_MODE Set this environment variable to enable test mode. This enables daemons and tools to locate their socket and PID file relative to CTDB_BASE. When testing with multiple local daemons on a single machine this does 3 extra things: * Disables checks related to public IP addresses * Speeds up the initial recovery during startup at the expense of some consistency checking * Disables real-time scheduling CTDB_DEBUG_HUNG_SCRIPT_LOGFILE=FILENAME FILENAME specifies where log messages should go when debugging hung eventscripts. This is a testing option. See also CTDB_DEBUG_HUNG_SCRIPT. No default. Messages go to stdout/stderr and are logged to the same place as other CTDB log messages. CTDB_SYS_ETCDIR=DIRECTORY DIRECTORY containing system configuration files. This is used to provide alternate configuration when testing and should not need to be changed from the default. Default is /etc. CTDB_RUN_TIMEOUT_MONITOR=yes|no Whether CTDB should simulate timing out monitor events in local daemon tests. Default is no. CTDB_TEST_SAMBA_VERSION=VERSION VERSION is a 32-bit number containg the Samba major version in the most significant 16 bits and the minor version in the least significant 16 bits. This can be used to test CTDB's checking of incompatible versions without installing an incompatible version. This is probably best set like this: export CTDB_TEST_SAMBA_VERSION=$(( (4 << 16) | 12 )) CTDB_VARDIR=DIRECTORY DIRECTORY containing CTDB files that are modified at runtime. Defaults to /usr/local/var/lib/ctdb.
