WP_REST_Server class not found

[laverboy]

Today did a clean install of the phpunit test and when I ran phpunit I recieved the following error:

Fatal error: Class 'WP_REST_Server' not found in /private/tmp/wordpress-tests-lib/includes/spy-rest-server.php on line 3

It looks like Spy_REST_Server extends WP_REST_Server but WP_REST_Server does not exist in the latest Wordpress version.

I think you got broken trunk. Can you try a clean install again?

[danielbachhuber]

It may also be #2050

[laverboy]

It was a clean install. I'll try again though.

This is my project/plugin with the same problem:

Same issue here, but we're on a private repo so I implemented @danielbachhuber's fix from the above repo (bonny/WordPress-Simple-History#95) and that did the trick. Thanks.

Just so it's clear, the fix is to update your plugin or theme's copy of install-wp-tests.sh with https://raw.githubusercontent.com/wp-cli/wp-cli/master/templates/install-wp-tests.sh

I'll release WP-CLI v0.20.2 sometime next week so new projects don't get bitten by this. Every existing project will, unfortunately, need to be manually updated.
