Class 'Behat\Behat\Context\BehatContext' not found in PHP with Behat

Posted by: admin July 12, 2020 Leave a comment

Questions:

I am trying to learn Behat using the tutorial on the website.

The first step goes OK, no errors appear.

But when I am changing the ls_project/features/bootstrap/FeatureContext.php, as shown in the tutorial second step, I am getting the following error: 'Behat\Behat\Context\BehatContext' not found.

The tutorial code, to which the change is applied:

# features/bootstrap/FeatureContext.php
<?php

use Behat\Behat\Context\BehatContext,
    Behat\Behat\Exception\PendingException;
use Behat\Gherkin\Node\PyStringNode,
    Behat\Gherkin\Node\TableNode;

class FeatureContext extends BehatContext
{
    /**
     * @Given /^I am in a directory "([^"]*)"$/
     */
    public function iAmInADirectory($dir)
    {
        if (!file_exists($dir)) {
            mkdir($dir);
        }
        chdir($dir);
    }
}

The full error log:

Could anyone please help me resolving this issue?

How to&Answers:

It appears you’ve installed Behat v3, but you’re following Behat 2 docs.

Behat 3

Behat 3 doesn’t have the Behat\Behat\Context\BehatContext class. It’s got a Behat\Behat\Context\Context interface:

use Behat\Behat\Context\Context;

class FeatureContext implements Context
{
    // ...
}

In composer.json:

{
    "require-dev": {
        "behat/behat": "~3.1"
    },
    "config": {
        "bin-dir": "bin/"
    }
}

Behat 2

Behat 2 uses the Behat\Behat\Context\BehatContext base class:

use Behat\Behat\Context\BehatContext;

class FeatureContext extends BehatContext
{
    // ...
}

In composer.json:

{
    "require-dev": {
        "behat/behat": "~2.5"
    },
    "config": {
        "bin-dir": "bin/"
    }
}

Answer:

In behat 3 there is different structure so you need to use new path to behat context which is in Behat/Behat/Context/Context

<?php

use Behat\Behat\Context\Context;
use Behat\MinkExtension\Context\RawMinkContext;
use Behat\Behat\Context\CustomSnippetAcceptingContext;
use Behat\Behat\Tester\Exception\PendingException;
use Behat\Gherkin\Node\PyStringNode;
use Behat\Gherkin\Node\TableNode;

class FeatureContext extends RawMinkContext implements Context {
}

So use this for example 🙂
