PHP预言之谜

Question

我有$entity_type->isSubClassOf('Drupal\Core\Entity\FieldableEntityInterface')->willReturn(TRUE);并且遇到了这个令人困惑的错误：

Prophecy\Exception\Call\UnexpectedCallException: Method call:
  - isSubclassOf("Drupal\Core\Entity\FieldableEntityInterface")
on Double\EntityTypeInterface\P121 was not expected, expected calls were:
  - isSubClassOf(exact("Drupal\Core\Entity\FieldableEntityInterface"))

Answer 1

在isSub之后，细心的读者会观察小写c与大写c。我将问题发布到https://github.com/phpspec/prophecy/issues/249
