(WP-CLI) Wordpress-Tests_Lib files not being created

Question

I'm trying to do WordPress Plugin Testing on Ubuntu 14.04 and I'm going through the setup of WP-CLI but I'm not able to download the necessary files (includes/functions.php).

This is the command I'm using:

bash bin/install-wp-tests.sh wordpress_test root '' localhost latest

This is the output:

+ install_wp
+ '[' -d /tmp/wordpress/ ']'
+ return
+ install_test_suite
++ uname -s
+ [[ Linux == \D\a\r\w\i\n ]]
+ local ioption=-i
+ '[' '!' -d /tmp/wordpress-tests-lib ']'
+ cd /tmp/wordpress-tests-lib
+ '[' '!' -f wp-tests-config.php ']'
+ download https://develop.svn.wordpress.org/trunk/wp-tests-config-sample.php /tmp/wordpress-tests-lib/wp-tests-config.php
++ which curl
+ '[' /opt/lampp/bin/curl ']'
+ curl -s https://develop.svn.wordpress.org/trunk/wp-tests-config-sample.php
+ sed -i 's:dirname( __FILE__ ) . '\''/src/'\'':'\''/tmp/wordpress/'\'':' /tmp/wordpress-tests-lib/wp-tests-config.php
+ sed -i s/youremptytestdbnamehere/wordpress_test/ /tmp/wordpress-tests-lib/wp-tests-config.php
+ sed -i s/yourusernamehere/root/ /tmp/wordpress-tests-lib/wp-tests-config.php
+ sed -i s/yourpasswordhere// /tmp/wordpress-tests-lib/wp-tests-config.php
+ sed -i 's|localhost|localhost|' /tmp/wordpress-tests-lib/wp-tests-config.php
+ install_db
+ PARTS=(${DB_HOST//\:/ })
+ local PARTS
+ local DB_HOSTNAME=localhost
+ local DB_SOCK_OR_PORT=
+ local EXTRA=
+ '[' -z localhost ']'
++ echo
++ grep -e '^[0-9]\{1,\}$'
+ '[' ']'
+ '[' -z ']'
+ '[' -z localhost ']'
+ EXTRA=' --host=localhost --protocol=tcp'
+ mysqladmin create wordpress_test --user=root --password= --host=localhost --protocol=tcp
Warning: Using a password on the command line interface can be insecure.

On using the phpunit command it throws an error:

Fatal error: require_once(): Failed opening required '/tmp/wordpress-tests-lib/includes/functions.php' (include_path='.:/opt/lampp/lib/php')

I'm at the office so I think the firewall could be blocking this command, though I have set a proxy in /etc/environment.

Help is appreciated.

Wordpress can't be tested with PHPUnit. – Hexamethylenetetramine

@zdenek-machek - Your statement is wrong. PHPUnit is used to test core and can be used in conjunction with WP-CLI. – Trehala

Did you end up finding a solution for this? – Palma

Answer 1

I had this problem and here is what you might try:

1. Confirm that /tmp/wordpress-tests-lib is missing the includes directory.

2. Confirm that you have svn installed on the machine. If not run sudo apt-get install subversion

3. Delete the /tmp/wordpress-tests-lib folder

4. Inside your plugin directory open up the bin/install-wp-tests.sh file and remove the quiet flag on the Subversion call. Change this line:

   svn co --quiet https://develop.svn.wordpress.org/${WP_TESTS_TAG}/tests/phpunit/includes/ $WP_TESTS_DIR/includes
   
   to
   
   svn co https://develop.svn.wordpress.org/${WP_TESTS_TAG}/tests/phpunit/includes/ $WP_TESTS_DIR/includes
   

5. Run the install shell script command again.

You should now be able to run PHPUnit and see the one default test passes.

Thanks, it hasn't solved the problem. I'm dealing with a third-party repo, but I'm pretty sure the code I've added is correct regardless of this test-suite issue – Crimea

I had this exact error, and this solution (simply removing --quiet from the install script) solved the problem for me. – Chandos

Wow - yes this worked - does anyone know why removing --quiet makes a difference? – Offcenter

Answer 2

I was having the same issue; resolved it by following the instructions here: https://github.com/wp-cli/wp-cli/wiki/Plugin-Unit-Tests . Specifically, I needed to initialize the testing environment.

bash bin/install-wp-tests.sh wordpress_test root '' localhost latest

where wordpress_test is test database, root is DB user and '' contains password.
