@red15 we let odoo run their test on their own addons, eventually we will have an automated travis for OCB, but for now the purpose of travis in **an OCA addon repo** is to test the addons comprised inside. 

We do not test and **should not** test every addon in Odoo.

`--test-enable` is not included in the line you commented on because that line is the pre-loading line. It initializes the database and will fail if modules have missing dependencies, bad views, and more generic error.

The following line (L43) tests using coverage in order to publish which lines are run in **unittests** not during initialization. It will test using only the addons in the repo using the `python -c ...`.

Again, running all tests is not the point of this. We don't care if the unittests of an unrelated module fail. We don't want other repos failing to make modules in my PR fail. We don't want to wait 20 extra minutes to install every module under the sun every time we fix the view of one module in the OCB web addons module.
