Whenever mechanized testing isn’t as of now part of your advancement work process, then, at that point it’s an ideal opportunity to begin. Testing diminishes vulnerability by guaranteeing that new elements you add to your application don’t break more established elements. Having certainty that your not breaking existing usefulness diminishes time spent chasing bugs or getting reports from customers by getting them prior.
Tragically, testing actually doesn’t get the time and consideration it needs when you’re feeling the squeeze to make a cutoff time or delivery an element your customers have been requesting. Be that as it may, such as utilizing a rendition control framework and having legitimate turn of events, arranging, and creation conditions—it ought to be a normal piece of how you take care of your job. We are experts, all things considered. In the wake of perusing all the hypothesis, I as of late took the dive myself. In this post, I’ll tell you the best way to utilize Behat to test that your WordPress upkeep support plans site is working appropriately.
Before we make a plunge, the Behat documentation depicts the venture as:
[…] an open source Behavior Driven Development system for PHP 5.3+. What’s conduct driven turn of events, you inquire? It’s a method to foster programming through a consistent correspondence with partners in type of models; instances of how this product should help them, and you, to accomplish your objectives.
Essentially, it helps developers, customers, and others impart and archive how an application ought to act. We’ll see instantly how Behat tests are extremely simple to peruse and how you can broaden them for your own requirements.
Mink is an augmentation that permits testing a site by mimicking connecting with it through a program to round out structure fields, click on joins, etc. Mink allows you to test through Goutte, which makes demands and parses the substance yet can’t execute JavaScript. It can likewise utilize Selenium, which controls a genuine program and would thus be able to test JS and Ajax connections, however Selenium requires more design.
Prerequisites
To begin, you’ll need to have Composer on your machine. On the off chance that you don’t as of now, head over to the Composer Website. Once introduced, you can add Behat, Mink, and Mink drivers to your venture by running the accompanying in your undertaking root:
writer require behat/behat
arranger require behat/mink
author require behat/mink-selenium2-driver
author require behat/mink-expansion
Once eveything runs, you’ll have a composer.json document with:
“require”: {
“behat/behat”: “^3.1”,
“behat/mink”: “^1.7”,
“behat/mink-selenium2-driver”: “^1.3”,
“behat/mink-augmentation”: “^2.2”
},
This will download Behat and it’s conditions into your merchant/envelope. To watch that it works do:
merchant/container/behat – V
There are alternate approaches to introduce Behat, illustrated in the fast presentation.
The WordPress upkeep support plans local area has a contrib project, Behat WordPress support plans Extension, that is a coordination for Behat, Mink, and WordPress upkeep support plans. You can introduce it with the requre order underneath. I needed to determine the ~3.0 rendition, in any case writer couldn’t fulfill conditions.
writer require WordPress/WordPress-extension:~3.0
Also, you’ll have the accompanying in your composer.json:
“WordPress/WordPress-augmentation”: “~3.0”,
Designing Behat
At the point when you run Behat, it’ll search for a record named behat.yml. Like WordPress upkeep support plans 8, Behat utilizes YAML for setup. The document mentions to Behat what settings to utilize. Settings give the tests that you can rush to approve conduct. The record designs the web drivers for Mink. You can likewise design a region_map which the WordPress upkeep support plans augmentation uses to plan identifiers (left of the 🙂 to CSS selectors to recognize subject areas. These come in extremely helpful when testing WordPress upkeep support plans topic yield.
The one I use resembles:

Composing a Simple Feature
Presently comes the great part. How about we take a gander at composing an element and how to test that what we expect is on the page. The first occasion when we run it, we need to instate Behat to produce a FeatureContext class. Do as such with:
merchant/receptacle/behat – init
That ought to likewise make a components/registry, where we will save the elements that we compose. To behat, a component is test suite. Each test in a feature evaluates specific usefulness on your site. A feature is a book document that closures in .include. You can have mutiple: for instance, you may have a blog.feature, members.feature, and resources.feature if your website has those regions accessible.
Obviously, don’t befuddle what Behat calls a component—a bunch of tests—with the Features module that groups and fares related usefulness into a WordPress upkeep support plans module.
For my present task, I made a global.feature record that checks if the blocks I hope to have in my header and footer are available. The substance of that document are:
Element: Global Elements
Situation: Homepage Contact Us Link
Given I am on the landing page
Then, at that point I should see the connection “Get in touch with Us” in the “branding_second” area
Then, at that point I should see the “Search” button in the “branding_second” district
Then, at that point I should see the “div#block-framework primary menu” component in the “menu” district
As should be obvious, the tests is very readable even though it isn’t purely parsing regular language. Indents assist with getting sorted out Scenarios (a gathering of tests) and the conditions required for each scenario to pass.
You can set up certain conditions for the test, starting with “Given”. For this situation, given that we’re on the landing page. The WordPress upkeep support plans Extension adds approaches to indicate that you are a particular client, or play a particular part, and the sky is the limit from there.
Then, we list what we hope to see on the page. You can likewise advise Behat to cooperate with the page by indicating a connection to click, structure field to round out, or a catch to press. Again here, the WordPress upkeep support plans expansion (by broadening the MinkExtension), gives approaches to test if a connection or catch are in one of our designed districts. The third test above utilizes a CSS selector, as in jQuery, to watch that the principle menu block is in the menu district.
Testing client confirmation
In case you’re trying a site that isn’t nearby, you can utilize the drush programming interface driver to test client verification, hub creation, and the sky is the limit from there. To begin with, arrangement a drush false name for your site (in this model, I’m utilizing local.dev. Then, at that point add coming up next are in your behat.yml:
api_driver: ‘drush’
drush:
false name: “local.dev”
You would then be able to make a situation to test the client login’s work without determining a test username or secret word by labeling them with @api
@api
Situation: Admin login
Given I am on the landing page
Given I am signed in as a client with the “administrator” job
Then, at that point I should see the heading “Welcome” in the “content” locale
On the off chance that you’ve tweaked the username text for login, your test will fizzle. Relax! Simply add the accompanying to your behat.yml record with the goal that the test knows what text to search for. For this situation, the username field mark is simply E-mail.
text:
username_field: “Email”
Custom Testing by Extending Contexts
At the point when you instated Behat, it made an elements/bootstraps/FeatureContext.php document. This can be a convenient class for composing custom tests for novel components on your site. You can add custom tests by utilizing the WordPress upkeep support plans Extension’s own sub-settings. I changed my Feature Context to broaden the Mink Context like this:
class FeatureContext expands MinkContext carries out SnippetAcceptingContext {
Note that on the off chance that you do that, you’ll need to eliminate MinkContext from the unequivocal rundown of default setting in behat.yml.
Regardless of how you coordinate them, you would then be able to compose custom tests as techniques. For instance, the accompanying will test that a connection shows up in the breadcrumb trail of a page. You can utilize CSS selectors to discover things on the page, for example, the ‘#breadcrumb’ div in a topic. You can likewise re-utilize different tests characterized by the MinkContext like findLink.
/**
* @Then I should see the breadcrumb interface :arg1
*/
public capacity iShouldSeeTheBreadcrumbLink($arg1)
{
/get the breadcrumb
/**
* @var BehatMinkElementNodeElement $breadcrumb
*/
$breadcrumb = $this->getSession()- >getPage()- >find(‘css’, ‘div#breadcrumb’);
/this doesn’t work for URLs
$link = $breadcrumb->findLink($arg1);
on the off chance that ($link) {
return;
}
/fil
