期望使用PHPUnit模拟对象的部分数组 - Expecting partial arrays using PHPUnit mock objects

在PHPUnit mock with()子句中测试多个数组键的最佳方法是什么?

例如，要测试调用第二个参数的方法是否为包含'foo'键的数组:

$this->stubDispatcher->expects($this->once())
        ->method('send')
        ->with('className', $this->arrayHasKey('foo'));

我想做的是像$this->arrayHasKey('foo', 'bar')这样的东西，而不是实际匹配数组的确切内容。

您可以直接将断言传递给->with()，但是它们的命名方式不同。

查看源代码:https://github.com/sebastianbergmann/phpunit/blob/3.5/PHPUnit/Framework/Assert.php#L2097和下面的列表。所有不以"assert"开头并返回new PHPUnit_Framework_* .

虽然我假设@David的答案有效，但我认为这种方法，使用logicalAnd()更干净/更容易阅读。

$mock->expects($this->once())->method("myMethod")->with(
    $this->logicalAnd(
        $this->arrayHasKey("foo"),
        $this->arrayHasKey("bar")
    )
);

<标题>工作示例

<?php

class MyTest extends PHPUnit_Framework_TestCase {
    public function testWorks() {
        $mock = $this->getMock("stdClass", array("myMethod"));
        $mock->expects($this->once())->method("myMethod")->with(
            $this->logicalAnd(
                $this->arrayHasKey("foo"),
                $this->arrayHasKey("bar")
            )
        );
        $array = array("foo" => 1, "bar" => 2);
        $mock->myMethod($array);
    }
    public function testFails() {
        $mock = $this->getMock("stdClass", array("myMethod"));
        $mock->expects($this->once())->method("myMethod")->with(
            $this->logicalAnd(
                $this->arrayHasKey("foo"),
                $this->arrayHasKey("bar")
            )
        );
        $array = array("foo" => 1);
        $mock->myMethod($array);
    }
}

你可以使用一个回调来做多个断言。

$this->stubDispatcher->expects($this->once())
     ->method('send')
     ->will($this->returnCallback(function($class, $array) {
             self::assertEquals('className', $class);
             self::assertArrayHasKey('foo', $array);
             self::assertArrayHasKey('bar', $array);
     }));

Edit:如果您想对某些参数进行基本断言，对其他参数进行更复杂的断言，可以添加with()。

$this->stubDispatcher->expects($this->once())
     ->method('send')
     ->with('className', $this->anything())
     ->will($this->returnCallback(function($class, $array) {
             self::assertArrayHasKey('foo', $array);
             self::assertArrayHasKey('bar', $array);
     }));

要非常清楚，您不应该将$this->returnCallback()传递给with()。returnValue()和throwException()相同。这些都是告诉mock在调用方法时该做什么的指令。with()用于告诉mock应该接受哪些参数。
