 Here's how to run the test suite:
 
-- Install the correct version of the drone-cli package.  As of this
-  writing, the correct drone-cli version is
-  [1.2.0](https://docs.drone.io/cli/install/).
-- Ensure you have enough free disk space.  You will need at least
-  15-20 Gb of free disk space to hold all of the containers drone
-  creates (a default AWS or GCE disk size won't work -- see
-  [#6243](https://github.com/go-gitea/gitea/issues/6243)).
-- Change into the base directory of your copy of the gitea repository,
-  and run `drone exec --event pull_request`.
-- At the moment `drone exec` doesn't support the Docker Toolbox on Windows 10
-  (see [drone-cli#135](https://github.com/drone/drone-cli/issues/135))

-The drone version, command line, and disk requirements do change over
-time (see [#4053](https://github.com/go-gitea/gitea/issues/4053) and
-[#6243](https://github.com/go-gitea/gitea/issues/6243)); if you
-discover any issues, please feel free to send us a pull request to
