Behat中外部文件中的步骤定义 [英] Step definitions in external files in Behat

问题描述

默认情况下，behat在名为FeatureContext的文件中查找步骤定义(一个文件中的所有步骤).
有很多步骤，很难维护这么大的文件.

Behat by default looks for the step definitions in file named FeatureContext (all steps in one file).
Having a lot of steps, it's hard to maintain such a big file.

我希望每个功能文件有一个定义文件.

I'd like to have one definition file per feature file.

如何在外部文件中具有步骤定义?

How can I have step definitions in external files?

例如

homepage.feature
HomepageContext extends FeatureContext

推荐答案

使用类继承和单独的上下文.

Use class inheritance and separate contexts.

# /features/contexts/
AbstractContext extends BehatContext {}
FeaturenameContext extends AbstractContext {}

然后在/feature/FeatureContext.php中导入上下文文件:

Then in /feature/FeatureContext.php import the context files:

/**
 * Initializes context.
 * Every scenario gets it's own context object.
 *
 * @param array $parameters context parameters (set up via behat.yml)
 */
public function __construct(array $parameters) {

    // import all context classes from context directory, except the abstract one

    $filesToSkip = array('AbstractContext.php');

    $path = dirname(__FILE__) . '/../contexts/';
    $it = new RecursiveDirectoryIterator($path);
    /** @var $file  SplFileInfo */
    foreach ($it as $file) {
        if (!$file->isDir()) {
           $name = $file->getFilename();
           if (!in_array($name, $filesToSkip)) {
               $class = pathinfo($name, PATHINFO_FILENAME);
               require_once dirname(__FILE__) . '/../context/' . $name;
               $this->useContext($class, new $class($parameters));
           }
        }
    }
}
