@schlessera I have manually tested and verified removal of data on local setup, I am not sure how to go about adding tests for the same, please let me know if a test is required for this change. Thanks.

There are already existing tests for the site empty command here: https://github.com/wp-cli/entity-command/blob/v2.0.7/features/site-empty.feature

You can just add to these to verify the logic with the following test:

• add an entry to the wp_links table;
• run site empty;
• query the SELECT COUNT(*) from $wpdb->links and verify that the count is zero.

@schlessera the build seems to have passed, but there seems to be some issue with travis config, can you please take look when time permits? Thanks.

If the travis config isn't valid, maybe I can create a PR to update that as well, seems like a good option to use automated script to add updates across repos.

@thrijith I'm pushing PRs to all repos right now to fix the Travis warning.
