WordPress Plugin Acceptance Test with Codeception on VVV - Typist Tech

Tutorial on how to leverage Varying Vagrant Vagrants, Codeception and wp-browser to write acceptance tests for WordPress plugins.

WordPress Plugin Acceptance Test with Codeception on VVV - Typist Tech

Development | typist.tech | Jan. 12, 2017

Ever anxious about pushing new release of WordPress plugin causing the white screen of death on your clients’ sites? You should write some acceptance tests! I will demonstrate how to leverage Varying Vagrant Vagrants, Codeception and wp-browser to write acceptance tests for WordPress plugins. Codeception is a PHP testing framework built on PHPUnit that automates acceptance testing. It does functional and unit tests also.
wp-browser is a WordPress specific set of extensions for Codeception written by theAverageDev.
The package includes a class extending Codeception PhpBrowser module that adds WordPress related assertions for cest and cept tests, an extension of Codeception own Db module meant to allow for more comfortable WordPress specific database handling and testing and a class taking care of installing and loading a WordPress installation relying on WordPress automated testing suite.
We’ll run our tests from within VVV because WP CLI, Node, and Composer are already installed for us there.
Before we actually writing the tests, we need a WordPress installation and a plugin to test. I use my plugin Remove Medium Cross Links as an example. All it does is remove the medium

Running WordPress Plugin Acceptance Tests on TravisCI - Typist Tech

Tutorial: How to run WordPress plugin acceptance tests on TravisCI

Running WordPress Plugin Acceptance Tests on TravisCI - Typist Tech

Tutorials | typist.tech | Mar. 12, 2017

We have written come acceptance tests in the last tutorial. Time to run them on the cloud. No way I would spend 10 minutes to wait for my tests ran for multiple PHP and WordPress versions. Continue from the last tutorial, I’ve removed some unused pieces and added PHP_CodeSniffer to the project. Nothing related to acceptance testing. Head over to the GitHub repo if you are interested.
A problem I found is that the tests failed randomly. The reason is that our tests tries to click some links before they show up on the screen. Adding $I->waitForElement('some element', 10); solves the problem.
Secondly, when changing the screen size, the link
Acceptance Test for rmcl fails out of the screen. Adding
$I->click('Acceptance Test for rmcl'); solves it.
$I->amOnpage('/');
$I->waitForElement('p.site-description', 10);
$I->scrollTo(['css' => 'h2.entry-title']);
You can run the tests on real browsers on TravisCI with Sauce Labs. But it’s too slow for me. I opt for PhantomJS instead.
The Selenium server I used the last tutorial becomes buggy. I switched to use PhantomJS lately.
$ composer require --dev  jakoch/phantomjs-installer neronmoon/scriptsdev site5/phantoman

What is worst than having downtime? Answer: Having downtime without noticing it. Here come Uptime Robot, a free service let you create 50 monitors that checks every 5 minutes, not to mention email alert, mobile apps, API support and public status pages. Uptime Robot homepage
Head to Uptime Robot’s website and create an account. You have to verify your email address before continue. This is probably the hardest part in this tutorial.
Upon logging into the dashboard, add a new HTTP monitor using the button on the top left corner. Enter a human-readable name and the URL you want to monitor. I use Typist Tech’s homepage as an example. Make sure you also selected “Alert Contacts To Notify”.
Uptime Robot will check this URL every 5 minutes, if 4xx or 5xx response is returned, it makes several more checks from other locations in the next 30 seconds. If the URL is still down, it sends an alert.
Click To Tweet
Let’s add a keyword monitor. Uptime Robot checks my site tagline and alerts me if tagline not found.
Which Pages Should I Monitor?
It’s totally up to you. For a typical WordPress blog, I would suggest:
Homepage
Blog page
XML Sitemap
Contact page

Ensure WP Corn Runs On Time - Typist Tech

How to configure WP Cron to work properly via Linux crontab and Uptime Robot. Ensure WP Cron runs on time.

Ensure WP Corn Runs On Time - Typist Tech

Tutorials | typist.tech | Jan. 7, 2017

WP Corn is the schedule system implementation of WordPress. Unlike linux cron, it doesn’t guarantee jobs are performed on time. Ever wondered why your scheduled posts not posted at specific time but suddenly published when you log in to WordPress dashboard to check out what’s wrong? You are the victim of WP cron. Scheduled jobs are saved into database and wait for WP Cron to perform them. However, unlike traditional corn systems, it’s doesn’t watch the clock periodically.
Click To Tweet
On a low-traffic WordPress site, WP Cron often perform the scheduled jobs beyond their specific time because nobody visits WordPress. Thus, nobody triggers WP Corn to check for scheduled jobs. Finally, someone visit WordPress and fires too many jobs, causing PHP timeouts.
On the other hand, high-traffic sites trigger WP Cron too often. As jobs are saved in database, querying for cron jobs become a waste of resource. Worse still, multiple WP Corn instances might performing the same job at the same time. This could be problem if the jobs are not idempotent (safely execute multiple times). Lucky for you, WordPress has a better locking system and much less issues about this is reported

Hosting WordPress on Heroku? Think Again! - Typist Tech

Hosting WordPress on Heroku? Think Again! - Typist Tech

Community | typist.tech | Dec. 26, 2016

Ever think about hosting WordPress sites on Heroku? Think again. It’s not as easy as deploying Rails applications. In fact, it’s a headache. Besides the limits you find in the official document, I am showing you some of my thoughts on Heroku WordPress hosting. Heroku’s Ephemeral Filesystem
Each dyno(Heroku’s term on its servers) gets its own ephemeral file system. When you uploaded an image, the image is stored on one of the dyno only. The images will be erased after dyno restart. Worse still, Dynos crash if you try to write to its file systems.
Here comes the solution: Offload media files to Amazon S3. Delicious Brains have written an excellent plugin for hooking S3 into WordPress’ media library seamlessly.
Besides, you need to stop editing the source code from WP admin. Add these two lines intowp-config.php
Also, auto WordPress core / theme / plugin updates should be disabled. This handy plugin does the job. Managing the updates by Git or Dropbox is necessary.
Moreover, the ephemeral filesystem might break your caching and minifying plugins. You have to Batcache with the Memcachier add-on, or plugins that write to an external server.
Heroku doesn’t
