wp-cli: unable to run phpunit on MAMP

Question

I'm following the plugin test setup/install instructions. I got wp scaffold plugin-tests my-plugin to run. But then at the next step when I try to run bash bin/install-wp-tests.sh wordpress_test root '' localhost latest I get the following error:

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to MySQL server on 'localhost' (61)'
Check that mysqld is running on localhost and that the port is 3306.
You can check this by doing 'telnet localhost 3306'

My local Wordpress site is running with MAMP (which is working). I'm not sure if that's relevant for the install script since I think it's creating a temporary DB to run the tests... Does it matter if it uses the built-in OSX mysql or MAMP's MySQL?

Here's the output from wp --info

$ ./vendor/wp-cli/wp-cli/bin/wp --info
PHP binary: /Applications/MAMP/bin/php/php5.6.10/bin/php
PHP version:    5.6.10
php.ini used:   /Applications/MAMP/bin/php/php5.6.10/conf/php.ini
WP-CLI root dir:    /Applications/MAMP/htdocs/pipeline/wp-content/plugins/wp-github-pipeline/vendor/wp-cli/wp-cli
WP-CLI global config:   
WP-CLI project config:  
WP-CLI version: 0.19.2

Update 2 I figured out that originally MySQL wasn't installed... that's why I couldn't connect! But now it is. I ran the install script, and this works...

$ ./vendor/wp-cli/wp-cli/bin/wp db tables
wp_users
wp_usermeta
wp_posts
wp_comments
wp_links
wp_options
wp_postmeta
wp_terms
wp_term_taxonomy
wp_term_relationships
wp_commentmeta

But when I run phpunit I get this:

$ phpunit
PHP Warning:  mysqli_real_connect(): (HY000/2002): No such file or directory in /private/tmp/wordpress/wp-includes/wp-db.php on line 1452
PHP Stack trace:

Warning: mysqli_real_connect(): (HY000/2002): No such file or directory in /private/tmp/wordpress/wp-includes/wp-db.php on line 1452

Part of my problem is that I'm not clear on whether wp-cli should be running entirely on native (cli) PHP/Mysql, or MAMP's PHP/Mysql, or some combination of both.

Update 4 I'm pretty sure the final problem is that phpunit needs to be installed in MAMP, but I'm running it from OSX...

$which phpunit
/usr/bin/phpunit

Mentioned in this gist.

Update 6

It turns out you can no longer install phpunit using pear. So I added it as a composer dependency under require-dev, but when I run that version I get the same error!

$ ./vendor/phpunit/phpunit/phpunit
PHP Warning:  mysqli_real_connect(): (HY000/1045): Access denied for user 'root'@'localhost' (using password: NO) in /private/tmp/wordpress/wp-includes/wp-db.php on line 1452

Warning: mysqli_real_connect(): (HY000/1045): Access denied for user 'root'@'localhost' (using password: NO) in /private/tmp/wordpress/wp-includes/wp-db.php on line 1452

I even added it to my path to be sure...

$ which phpunit
/Applications/MAMP/htdocs/pipeline/wp-content/plugins/wp-github-pipeline/vendor/phpunit/phpunit/phpunit

Update 7

After reading the comments at the bottom of this blog post, I see that the install script was referencing the OSX version of mysqladmin. I'm not sure if this matters, but I prepended MAMPs version in the path, and re-ran the install script. It seems to install the Wordpress files in /tmp/ anyway. Same error when I run phpunit

By default, mamp runs mysql on port 8889. Have you changed it ? What is the output of telnet localhost 3306 ? — Aserre

@Ploutox I did change it so MAMP runs mysql on the standard port. I added the output of telnet to the question above. — emersonthis

Yes it matters which mysql is being used. Did you try exporting MAMP's mysql and mysqladmin as described here? stackoverflow.com/a/29990624/2646526 — heenenee

pls check if mysql runs via Terminal: ps aux | grep sql. Furthermore with this command you can check what runs on which port: lsof -i -P | grep -i "listen". If mysql is running on the correct port, do you have perhaps a firewall which gets into your way? Ohter option, can you connect to mysql if you run the command mysql -uroot -p in the terminal? — jerik

Could you go to localhost:3306 and see if a file named 'download' is downloaded? Otherwise your mysql is not running on that port(or not running at all). — GuyT

If you are using MAMP, issue may be relevant to your MySQL Server settings. Make sure to check Allow network access option in MAMP settings:

Update 1

Create phpinfo.php file in your root directory (usually /Applications/MAMP/htdocs for MAMP). Paste the following content:

<?php phpinfo() ?>

Then check the Loaded Configuration File property. Open it using nano or other text editor in terminal. Then find and change this 3 propertiespdo_mysql.default_socket, mysql.default_socket, mysqli.default_socket to your socket file.

Can the radio be set to "Only from this Mac"?

Nikita Zernov Over a year ago

If you need to be able to connect to MySQL locally choose only from this Mac, otherwise from other computers

emersonthis Over a year ago

So I can run wp db tables and it works. But when I run phpunit it returns the "Unable to connect to database" screen...

Nikita Zernov Over a year ago

Does Wordpress work? Does it connect to MySQL database?

emersonthis Over a year ago

I think so. Just added Update 2 above, which elaborates

I finally got phpunit to run!!

I couldn't find this documented anywhere...

At some point during the installation process, Wordpress core files are installed in /tmp/wordpress/. That Wordpress installation has it's own wp-config.php file which had incorrect values. When I corrected those values to match the wp-config.php of my site, phpunit worked without problems!

I'm not sure how this happened, but my theory is that the first time I ran the install script with the wrong credentials. But later I corrected them (I re-ran the install script several times). But I think the install script didn't overwrite the original files.

+400 to @Nikita Zernov for so much help!

Normally if you ftp or telnet to localhost you'll get conection refused, if you want to fix the error change your httpd.conf to ServerName localhost

Also if you want to do remote login try enable remote login by going to System Preferences -> Sharing -> Remote Login box (check it).

For MySQL Problem

Make sure ‘skip-networking’ is commented out in configuration file(in this case /opt/local/etc/mysql55/my.conf) or when starting mysql server, it does’t start with ‘–skip-networking’

In skip-networking mode, the mysql instance doesn’t “listen for TCP/IP connections at all. All interaction with mysqld must be made using named pipes or shared memory (on Windows) or Unix socket files (on Unix)” from MySql Docs

MAMP appears to have it's own magical version of that property. In my.cnf I see MAMP_skip-networking_MAMP. Do you think I should comment this out? What is your theory?
