Running the tests using zc.buildout

Products.ZMySQLDA ships with its own buildout.cfg file for setting up a development buildout:

$ cd Products.ZMySQLDA
$ python3 -m venv .
$ bin/pip install -U pip wheel
$ bin/pip install "setuptools<52" zc.buildout tox twine
$ bin/buildout

Once you have a buildout, the tests can be run as follows:

$ bin/test
Running tests at level 1
Running zope.testrunner.layer.UnitTests tests:
  Set up zope.testrunner.layer.UnitTests in 0.000 seconds.
  Ran 62 tests with 0 failures and 0 errors in 0.043 seconds.
Tearing down left over layers:
  Tear down zope.testrunner.layer.UnitTests in 0.000 seconds.

To run tests for all supported Python versions, code coverage and a PEP-8 coding style checker, you can use tox after completing the buildout step above:

$ bin/tox
GLOB sdist-make: ...

Running the functional tests

Some tests are hard or even impossible to perform without a real running database backend. During a normal test run they will be skipped, and you will see output like this:

Total: 62 tests, 0 failures, 0 errors and 5 skipped in 0.090 seconds.

To run those functional tests you need to have a MySQL/MariaDB server running and listening on the standard unix socket, normally located at /tmp/mysl.sock. This database server must have a database named zmysqldatest that can be accessed by a user zmysqldatest with password zmysqldatest. To set this up, log into the running database server with an admin user and execute the following statements:

mysql> CREATE DATABASE IF NOT EXISTS zmysqldatest;
mysql> CREATE USER 'zmysqldatest'@'localhost' IDENTIFIED BY 'zmysqldatest';
mysql> GRANT ALL PRIVILEGES ON zmysqldatest.* TO 'zmysqldatest'@'localhost';

If everything worked you’ll see test output like this:

Total: 62 tests, 0 failures, 0 errors and 0 skipped in 0.105 seconds.

If the functional tests are still skipped, uncomment the print call in the _mySQLNotAvailable function in the module Products.ZMySQLDA.tests.base. It will print any errors emitted by the database server.

Building the documentation using zc.buildout

The Products.ZMySQLDA buildout installs the Sphinx scripts required to build the documentation, including testing its code snippets:

$ cd docs
$ make html
build succeeded.

The HTML pages are in _build/html.

Making a release

These instructions assume that you have a development sandbox set up using zc.buildout as the scripts used here are generated by the buildout.

$ bin/buildout -N
$ bin/buildout setup sdist bdist_wheel
$ bin/twine upload -s dist/Products.ZMySQLDA-X.X.X*

The bin/buildout step will make sure the correct package information is used.
