PHPUnit:如何断言一个类扩展了另一个类? [英] PHPUnit: How to assert that a class extends another class?

问题描述

在我的PHPUnit测试中，我想断言我正在测试的类扩展了另一个类.我该如何使用PHPUnit?

In my PHPUnit test, I would like to assert that the class that I am testing extends another class. How can I do this with PHPUnit?

推荐答案

使用

Use assertInstanceOf() instead of PHP's built in instanceof operator or functions so that you get a meaningful failure message.

function testInstanceOf() {
    $obj = new Foo;
    self::assertInstanceOf('Bar', $obj);
}

...

Failed asserting that <Foo> is an instance of class "Bar".
