# Silverstripe Integration for Behat

[![CI](https://github.com/silverstripe/silverstripe-behat-extension/actions/workflows/ci.yml/badge.svg)](https://github.com/silverstripe/silverstripe-behat-extension/actions/workflows/ci.yml)
[![Silverstripe supported module](https://img.shields.io/badge/silverstripe-supported-0071C4.svg)](https://www.silverstripe.org/software/addons/silverstripe-commercially-supported-module-list/)

## Overview

[Behat](http://behat.org) is a testing framework for behaviour-driven development.
Because it primarily interacts with your website through a browser,
you don't need any specific integration tools to get it going with
a basic Silverstripe website, simply follow the
[standard Behat usage instructions](http://docs.behat.org/en/latest/user_guide.html).

This extension comes in handy if you want to go beyond
interacting with an existing website and database,
for example make changes to your database content which
would need to be rolled back to a "clean slate" later on.

It provides the following helpers:

 * Provide access to Silverstripe classes in your Behat contexts
 * Set up a temporary database automatically
 * Reset the database content on every scenario
 * Prebuilt Contexts for SilverStripe's login forms and other common tasks
 * Creating of member fixtures with predefined permissions
 * YML fixture definitions inside your Behat scenarios
 * Waiting for jQuery Ajax responses (rather than fixed wait timers)
 * Captures JavaScript errors and logs them through Selenium
 * Saves screenshots to filesystem whenever an assertion error is detected

In order to achieve this, the extension makes one basic assumption:
Your Behat tests are run from the same application as the tested
Silverstripe codebase, on a locally hosted website from the same codebase.
This is important because we need access to the underlying SilverStripe
PHP classes. You can of course use a remote browser to do the actual testing.

Note: The extension has only been tested with the `selenium2` Mink driver.

## Installation

Simply [install Silverstripe through Composer](http://doc.silverstripe.org/framework/en/installation/composer).
Skip this step if adding the module to an existing project.

	composer create-project silverstripe/installer my-test-project 4.x-dev

Switch to the newly created webroot, and add the Silverstripe Behat extension.

	cd my-test-project
	composer require --dev silverstripe/behat-extension

Download the standalone [Google Chrome WebDriver](http://chromedriver.storage.googleapis.com/index.html?path=2.8/)

Now install the Silverstripe project as usual by opening it in a browser and following the instructions.
Protip: You can skip this step by using `[SS_DATABASE_CHOOSE_NAME]` in a global
[`.env`](https://docs.silverstripe.org/en/getting_started/environment_management/) file one level above the webroot.

Unless you have [`SS_BASE_URL`](http://doc.silverstripe.org/framework/en/topics/commandline#configuration) set up, 
you also need to specify the URL for your webroot. Either add it to the existing `behat.yml` configuration file
in your project root, or set is as an environment variable in your terminal session:

	export BEHAT_PARAMS="extensions[SilverStripe\BehatExtension\MinkExtension][base_url]=http://localhost/"

## Usage

### Starting ChromeDriver

You can run the server locally in a separate Terminal session:

    chromedriver

### Running the Tests

Now you can run the tests (for example for the `framework` module):

	vendor/bin/behat @framework

Or even run a single scenario by it's name (supports regular expressions):

	vendor/bin/behat --name 'My scenario title' @framework

This will start a Chrome browser by default. Other browsers and profiles can be configured in `behat.yml`.

### Running with stand-alone command (requires Bash)

If running with `silverstripe/serve` and `chromedriver`, you can also use the following command
which will automatically start and stop these services for individual tests.

    vendor/bin/behat-ss @framework

This automates:
 - starting server
 - starting chromedriver
 - running behat
 - shutting down chromedriver
 - shutting down server

Make sure you set `SS_BASE_URL` to `http://localhost:8080` in `.env`

 * [Tutorial: Webservice Mocking with Phockito and TestSession](docs/webservice-mocking.md)
 * [Tutorial: Setting up Behat on CircleCI](docs/circleci-tutorial.md)

## Configuration

The Silverstripe installer already comes with a YML configuration
which is ready to run tests on the standalone ChromeDriver server,
located in the project root as `behat.yml`.

You should ensure that you have configured `SS_BASE_URL` in your `.env` file.

Generic Mink configuration settings are placed in `SilverStripe\BehatExtension\MinkExtension`,
which is a subclass of `Behat\MinkExtension\Extension`.

Overview of settings (all in the `extensions.SilverStripe\BehatExtension\Extension` path):

 * `ajax_steps`: Because Silverstripe uses AJAX requests quite extensively, we had to invent a way
to deal with them more efficiently and less verbose than just
Optional `ajax_steps` is used to match steps defined there so they can be "caught" by
[special AJAX handlers](http://blog.scur.pl/2012/06/ajax-callback-support-behat-mink/) that tweak the delays. You can either use a pipe delimited string or a list of substrings that match step definition.
 * `ajax_timeout`: Milliseconds after which an Ajax request is regarded as timed out,
 and the script continues with its assertions to avoid a deadlock (Default: 5000).
 * `screenshot_path`: Absolute path used to store screenshot of a last known state
of a failed step.
Screenshot names within that directory consist of feature file filename and line
number that failed.

## Module Initialisation

You're all set to start writing features now! Simply create `*.feature` files
anywhere in your codebase, and run them as shown above. We recommend the folder
structure of `tests/behat/features`, since its consistent with the common location
of SilverStripe's PHPUnit tests.

Behat tests rely on a `FeatureContext` class which contains step definitions,
and can be composed of other subcontexts, e.g. for SilverStripe-specific CMS steps
(details on [behat.org](http://docs.behat.org/quick_intro.html#the-context-class-featurecontext)).
Since step definitions are quite domain specific, its likely that you'll need your own context.
The Silverstripe Behat extension provides an initializer script which generates a template
in the recommended folder structure:

	vendor/bin/behat --init @mymodule --namespace="MyVendor\MyModule"

	Note: namespace is mandatory

You'll now have a class located in `mymodule/tests/behat/src/FeatureContext.php`,
which will have a psr-4 class mapping added to composer.json by default.
Also a folder for your features with `mymodule/tests/behat/features` will be created.
A `mymodule/behat.yml` is built, with a default suite named after the module.

## Available Step Definitions

The extension comes with several `BehatContext` subclasses come with some extra step defintions.
Some of them are just helpful in general website testing, other's are specific to SilverStripe.
To find out all available steps (and the files they are defined in), run the following:

	vendor/bin/behat @mymodule --definitions=i

Note: There are more specific step definitions in the Silverstripe `framework` module
for interacting with the CMS interfaces (see `framework/tests/behat/features/bootstrap`).
In addition to the dynamic list, a cheatsheet of available steps can be found at the end of this guide.

## Fixtures

Since each test run creates a new database, you can't rely on existing state unless
you explicitly define it.

### Database Defaults

The easiest way to get default data is through `DataObject->requireDefaultRecords()`.
Many modules already have this method defined, e.g. the `blog` module automatically
creates a default `BlogHolder` entry in the page tree. Sometimes these defaults can
be counterproductive though, so you need to "opt-in" to them, via the `@database-defaults`
tag placed at the top of your feature definition. The defaults are reset after each
scenario automatically.

### Inline Definition

If you need more flexibility and transparency about which records are being created,
use the inline definition syntax. The following example shows some syntax variations:

	Feature: Do something with pages
		As an site owner
		I want to manage pages

		Background:
			# Creates a new page without data. Can be accessed later under this identifier
			Given a "page" "Page 1"
			# Uses a custom RegistrationPage type
			And an "error page" "Register"
			# Creates a page with inline properties
			And a "page" "Page 2" with "URLSegment"="page-1" and "Content"="my page 1"
			# Field names can be tabular, and based on DataObject::$field_labels
			And the "page" "Page 3" has the following data
			 | Content | <blink> |
			 | My Property | foo |
			 | My Boolean | bar |
			# Pages are published by default, can be explicitly unpublished
			And the "page" "Page 1" is not published
			# Create a hierarchy, and reference a record created earlier
			And the "page" "Page 1.1" is a child of a "page" "Page 1"
			# Specific page type step
			And a "page" "My Redirect" which redirects to a "page" "Page 1"
			And a "member" "Website User" with "FavouritePage"="=>Page.Page 1"

		@javascript
		Scenario: View a page in the tree
			Given I am logged in with "ADMIN" permissions
			And I go to "/admin/pages"
			Then I should see "Page 1"

 * Fixtures are created where you defined them. If you want the fixtures to be created
   before every scenario, define them in 
   [Background](http://docs.behat.org/en/latest/user_guide/writing_scenarios.html#backgrounds).
   If you want them to be created only when a particular scenario runs, define them there.
 * Fixtures are cleared between scenarios.
 * The basic syntax works for all `DataObject` subclasses, but some specific
   notations like "is not published" requires extensions like `Hierarchy` to be applied to the class
 * Record types, identifiers, property names and property values need to be quoted
 * Record types (class names) can use more natural notation ("registration page" instead of "Registration Page")
 * Record types support the `$singular_name` notation which is also used to reference the types throughout the CMS.
   Record property names support the `$field_labels` notation in the same fashion.
 * Property values may also use a `=>` symbol to indicate relationships between records.
   The notation is `=><classname>.<identifier>`. For `has_many` or `many_many` relationships,
   multiple relationships can be separated by a comma.

## Writing Behat Tests

### Directory Structure

As a convention, Silverstripe Behat tests live in a `tests/behat` subfolder
of your module. You can create it with the following commands:

	mkdir -p mymodule/tests/behat/features/
	mkdir -p mymodule/tests/behat/src/

### FeatureContext

The generic [Behat usage instructions](http://docs.behat.org/en/latest/user_guide.html) apply
here as well. The only major difference is the base class from which
to extend your own `FeatureContext`: It should be `SilverStripeContext`
rather than `BehatContext`.

Example: mymodule/tests/behat/src/FeatureContext.php

	<?php
	namespace MyModule\Test\Behaviour;

	use SilverStripe\BehatExtension\Context\SilverStripeContext;

	class FeatureContext extends SilverStripeContext
	{
	}

### Screen Size

In some Selenium drivers you can
define the desired browser window size through a `capabilities` definition.
By default, Selenium doesn't support this though, so we've added a workaround
through an environment variable:

	BEHAT_SCREEN_SIZE=320x600 vendor/bin/behat

### Inspecting PHP sessions

Behat is executed from CLI, which in turn triggers web requests in a browser.
This browser session is associated PHP session information such as the logged-in user.
After every request, the session information is persisted on disk as part
of the `TestSessionEnvironment`, in order to share it with Behat CLI.

Example: Retrieve the currently logged-in member

    use SilverStripe\TestSession\TestsessionEnvironment;

	$env = Injector::inst()->get(TestSessionEnvironment::class);
	$state = $env->getState();
	if(isset($state->session['loggedInAs'])) {
		$member = \Member::get()->byID($state->session['loggedInAs']);
	} else {
		$member = null;
	}

## FAQ

### FeatureContext not found

This is most likely a problem with Composer's autoloading generator.
Check that you have "SilverStripe" mentioned in the `vendor/composer/autoload_classmap.php` file,
and call `composer dump-autoload` if not.

### How do I wait for asynchronous actions in my steps?

Sometimes you want to wait for an AJAX request or CSS animation to complete before
calling the next step/assertion. Mink provides a [wait() method](http://mink.behat.org/en/latest/guides/session.html)
for this purpose - just let the execution wait until a JavaScript expression satisfies your criteria.
It's pretty common to make this expression a CSS selector.
The Behat tests come with built-in support to wait for any pending `jQuery.ajax()` requests,
check `BasicContext->handleAjaxBeforeStep()` and the `ajax_steps` configuration option.

### Why does the module need to know about the framework path on the filesystem?

Sometimes Silverstripe needs to know the URL of your site. When you're visiting
your site in a web browser this is easy to work out, but if you're executing
scripts on the command-line, it has no way of knowing.

### How does the module interact with the SS database?

The module creates temporary database on init and is switching to the alternative
database session before every scenario by using `/dev/tests/setdb` TestRunner
endpoint.

It also populates this temporary database with the default records if necessary.

It is possible to include your own fixtures, it is explained further.

### Why do tests pass in a fresh installation, but fail in my own project?

Because we're testing the interface directly, any changes to the
viewed elements have the potential to disrupt testing.
By building a test database from scratch, we're trying to minimize this impact.
Some examples where things can go wrong nevertheless:

 * Thirdparty Silverstripe modules which install default data
 * Changes to the default interface language
 * Configurations which remove admin areas or specific fields

Currently there's no way to exclude offending modules from a test run.
You either have to adjust the tests to work around these changes,
or run tests on a "sandbox" projects without these modules.

### How do I debug when something goes wrong?

First, read the console output. Behat will tell you which steps have failed.

Silverstripe Behaviour Testing Framework also notifies you about some events.
It tries to catch some JavaScript errors and AJAX errors as well although it
is limited to errors that occur after the page is loaded.

Screenshot will be taken by the module every time the step is marked as failed.
Refer to configuration section above to know how to set up the screenshot path.

If you are unable to debug using the information collected with the above
methods, it is possible to delay the step execution by adding the following step:

    And I put a breakpoint

This will stop the execution of the tests until you press the return key in the
terminal. This is very useful when you want to look at the error or developer console
inside the browser or if you want to interact with the session page manually.

### Can I set breakpoints through XDebug?

If you have [XDebug](http://xdebug.org) set up, breakpoints are your friend.
The problem is that you can only connect the debugger to the PHP execution
in the CLI, or in the browser, not both at the same time.

First of all, ensure that `xdebug.remote_autostart` is set to `Off`,
otherwise you'll always have an active debugging session in CLI, never in the browser.

Then you can choose to enable XDebug for the current CLI run:

	XDEBUG_CONFIG="idekey=macgdbp" vendor/bin/behat

Or you can use the `TESTSESSION_PARAMS` environment variable to pass additional
parameters to `dev/testsession/start`, and debug in the browser instead.

	TESTSESSION_PARAMS="XDEBUG_SESSION_START=macgdbp" vendor/bin/behat @app

The `macgdbp` IDE key needs to match your `xdebug.idekey` php.ini setting.

### How do I set up continuous integration through Travis?

Check out the [travis.yml](https://github.com/silverstripe/silverstripe-framework/blob/master/.travis.yml)
in `silverstripe/framework` for a good example on how to set up Behat tests through 
[travis-ci.org](http://travis-ci.org).

### Transformations

Behat [transformations](http://docs.behat.org/en/v2.5/guides/2.definitions.html#step-argument-transformations)
have the ability to change step arguments based on their original value,
for example to cast any argument matching the `\d` regex into an actual PHP integer.

 * `/^(?:(the|a)) time of (?<val>.*)$/`: Transforms relative time statements compatible with 
 [strtotime()](http://www.php.net/manual/en/datetime.formats.relative.php). Example: "the time of 1 hour ago" might 
 return "22:00:00" if its currently "23:00:00".
 * `/^(?:(the|a)) date of (?<val>.*)$/`: Transforms relative date statements compatible with 
 [strtotime()](http://www.php.net/manual/en/datetime.formats.relative.php). Example: "the date of 2 days ago" might 
 return "2013-10-10" if its currently the 12th of October 2013.
 * `/^(?:(the|a)) datetime of (?<val>.*)$/`: Transforms relative date and time statements compatible with
