Overview

Mysqltest is a brief functional test that provides the following:

• Creates and loads a sample mysql database
• Execute simple functional tests from the mysql-testsuite package

• Execute Lightweight stress tests on the sample database loaded by the dbload option

  juju deploy mysqltest
  juju deploy mysql
  juju add-relation mysql:db-admin mysqltest:db-admin

The charm uses juju actions. To run the simple database execute the following command:

juju action do  mysqltest/0 dbload

This will return an id that can be used to fetch the results:

juju action fetch --wait 0  id_value

Similarly actions can invoke the other options

juju action do  mysqltest/0  {testsuite or stress}

This charm provides the option to run simple funtional or stress tests. The options in the config.yaml file that can be set is the test-type variable. The options are dbload, testsuite, or stress by default dbload is set. The option can be changed with the following command:

Descrptions of test-type option

• dbload - load a sample database
• testsuite - run a basic subset functional tests supplied by mysql-testsuite.
• stress - run a lightweight stress test on the sample database loaded by dbload

NOTES:

• The sample database can be downloaded from launchpad at the following location:
  https://launchpad.net/test-db/employees-db-1/1.0.6/+download/employees_db-full-1.0.6.tar.bz2

The database contains about 300,000 employee records with 2.8 million salary entries. The export data is 167 MB, which is not huge, but heavy enough to be non-trivial for testing.

TODO

• Add more tests to the testsuite option. This will be easier in mysql 5.7 when the --do-test-list=file option is available and I can specify test cases instead of the wildcard function using the --do-test option

• Add a heavier stress test such as mysql-stress-test.pl or run the Performance Schema suite provided by mysqltestsuite
