PHP Unit Testing, revisited

See latest setup notes here: dotherightthing/generator-wpdtrt-plugin-boilerplate#28

---

When I last tried to set up Unit Testing, I ran into a suite of errors, but that was in a multi-site setup. This time I am using wptest, a standalone site which I set up just for testing plugins.

I'm following Pippin's tutorial on Unit Tests for WordPress Plugins – Setting Up Our Testing Suite.

Using $ in $.noConflict() mode

How to use the dollar sign as an alias for the jQuery object

Because the jQuery object is used so often, having a short alias is very useful and the dollar sign is so conventional that when people are looking at jQuery code, they are often looking for this dollar sign as an indicator that the jQuery object is being used.

Now we could use a simple assignment to say $ = jQuery and just leave it at that, but the issue is that we don't know if the dollar sign is being used by some other JavaScript library ... So in order to make sure that the dollar sign doesn't get overridden somewhere along the lines, we need to make the dollar sign a local variable for each function that we write

UTF-8

Some great information from UTF-8: The Secret of Character Encoding.

Meta tag

I've used the charset meta tag with a UTF-8 value for a long long time and now it's the default in HTML5.

While this can also be achieved on the server, the meta tag is an easy and human-readable way to instruct the browser to use UTF-8.

Autoloading and Namespaces

composer.json

This object instructs Composer to automatically require PHP files inside src, which use the namespace WPDTRT_Plugin:

"autoload": {
  "psr-4": {
 "DoTheRightThing\WPPlugin\\": "src/"

TLS (Transport Layer Security) and SSL (Secure Sockets Layer)

Summary

TLS (Transport Layer Security) and SSL (Secure Sockets Layer) are protocols that provide data encryption and authentication between applications and servers in scenarios where that data is being sent across an insecure network, such as checking your email. - SSL versus TLS – What’s the difference?

Key differences

• A program can initiate a secure connection with a server by Port ('explicit' - SSL), or by Protocol ('implicit' - TLS)
• A negotiation between the client and the server determines which protocol is used. This is based on which software is installed on each and how each is configured.
