4.9. Passing Options from mysql-test-run.pl to mysqld or mysqltest

mysql-test-run.pl supports several options that enable you to pass options to other programs. Each of these options takes a value consisting of one or more comma-separated options:

  • The --mysqld option tells mysql-test-run.pl to start the mysqld server with the named options. The following command causes --skip-innodb and --key_buffer_size=16384 to be passed to mysqld: 

    shell> mysql-test-run.pl --mysqld=--skip-innodb --mysqld=--key_buffer_size=16384

    Note how --mysqld needs to be repeated for each server option to add. It does not work to add several server options with one --mysqld even if enclosed in quotes, as that will be interpreted as a single server option (including spaces).

  • The --combination option is similar to --mysqld, but behaves differently. mysql-test-run.pl executes multiple test runs, using the options for each instance of --combination in successive runs. The following command passes --skip-innodb to mysqld for the first test run, and --innodb and --innodb-file-per-table for the second test run: 

    shell> mysql-test-run.pl
         --combination=--skip-innodb
         --combination=--innodb,--innodb-file-per-table

    If --combination is given only once, it has no effect.

    For test runs specific to a given test suite, an alternative to the use of the --combination option is to create a combinations file in the suite directory. The file should contain a section of options for each test run. For an example, see Section 4.12.1, “Controlling the Binary Log Format Used for an Entire Test Run”.
