Slony-I HEAD_20051208 Documentation Prev Fast_Backward Fast_Forward Next =============================================================================== ****** 21. Slony-I Test Bed Framework ****** As of version 1.2, Slony-I has a common test bed framework intended to better support performing a comprehensive set of tests. The code lives in the source tree under the tests directory. Here are some of the vital files... * run_test.sh This is the central script for running tests. Typical usage is thus: ./run_test.sh usage ./run_test.sh testname You need to specify the subdirectory name of the test set to be run; each such set is stored in a subdirectory of tests. You may need to set one or more of the following environment variables to reflect your local configuration. For instance, the writer runs "test1" against PostgreSQL 8.0.x using the following command line: PGBINDIR=/opt/OXRS/dbs/pgsql8/bin PGPORT=5532 PGUSER=cbbrowne ./run_test.sh test1 PGBINDIR This determines where the test scripts look for PostgreSQL and Slony- I binaries. The default is /usr/local/pgsql/bin There are also variables PGBINDIR1 thru PGBINDIR13 which allows you to specify a separate path for each database instance. That will be particularly useful when testing interoperability of Slony-I across different versions of PostgreSQL. In order to create a database of each respective version, you need to point to an initdb of the appropriate version. PGPORT This indicates what port the backend is on. By default, 5432 is used. There are also variables PORT1 thru PORT13 which allows you to specify a separate port number for each database instance. That will be particularly useful when testing interoperability of Slony-I across different versions of PostgreSQL. PGUSER By default, the user postgres is used; this is taken as the default user ID to use for all of the databases as the 'generic' user and as the user that a slon connects to its node as. There are also variables USER1 thru USER13 which allow specifying a separate user name for each database instance. As always, with Slony-I, this needs to be a PostgreSQL "superuser." WEAKUSER By default, this user is 'weakuser'. It is set up to have read-only permissions on the Slony-I schema and on the replicated tables. HOST By default, localhost is used. There are also variables HOST1 thru HOST13 which allow specifying a separate host for each database instance. DB1 thru DB13 By default, slonyregress1 thru slonyregress13 are used. You may override these from the environment. ENCODING By default, UNICODE is used, so that tests can create UTF8 tables and test the multibyte capabilities. =============================================================================== Prev Home Next Slony-I "Best Practices" Up More Slony-I Help
