WL#2856: Use scripts to cover more test cases
Affects: Server-7.1 — Status: Un-Assigned — Priority: Medium
Current NDB testing: 1) mysql-test, via mysqld - fixed tables and test cases (SQL) - single-threaded - no NDB restart testing 2) autotest, via C programs - fixed single tables and test cases (NDB API) - multi-threaded, presses NDB to the limit - tests NDB node and system restarts It seems useful to add a third type, mainly to cover more cases: 3) perl test scripts, via dbi:mysql - variable tables and test cases (SQL) - multi-threaded - can do NDB restarts - can look "outside" e.g. to verify local files Variable tests can mean random, or exhaustive when possible. The script itself will verify results by computing them. Multi-threading, unlike in 2) is not for pressing NDB on a single table, but to run parallel ops on different tables to find "global variable" problems in NDB. Implementation-wise there should be a file of perl modules (support for sql, mgm, etc) and the test scripts themselves. The scripts should be runnable standalone or via 1) and 2) using a welldefined way to pass environment and parameters.
