php - 在 phpunit 中连接约束

Question

我的问题是，我如何将子句中的约束与 phpunit 连接起来？在虚拟示例中:

$test->expects ($this->once())
     ->method ('increaseValue')
     ->with ($this->greaterThan (0)
     ->will ($this->returnValue (null));

方法increaseValue的参数必须大于0，但如果我需要评估这个参数必须小于10。

我如何连接 $this->lessThan(10)？

Answer 1

您可以使用logicalAnd 表达式:

$test->expects ($this->once())
     ->method ('increaseValue')
     ->with ($this->logicalAnd($this->greaterThan(0), $this->lessThan(10)))
     ->will ($this->returnValue (null));

有关可能功能的列表，请查看以下功能:PHPUnit/Framework/Assert.php不以“assert”开头的

完整示例

<?php

class mockMe {
    public function increaseValue($x) {
    }
}


class fooTest extends PHPUnit_Framework_TestCase {

    public function testMock() {
        $test = $this->getMock('mockMe');
        $test->expects($this->once())
             ->method('increaseValue')
             ->with($this->logicalAnd($this->greaterThan(0), $this->lessThan(10)))
             ->will($this->returnValue(null));
        $test->increaseValue(6);
    }

    public function testMockFails() {
        $test = $this->getMock('mockMe');
        $test->expects($this->once())
             ->method('increaseValue')
             ->with($this->logicalAnd($this->greaterThan(0), $this->lessThan(10)))
             ->will($this->returnValue(null));
        $test->increaseValue(12);
    }

}

结果

 phpunit blub.php

There was 1 failure:

1) fooTest::testMockFails
Expectation failed for method name is equal to <string:increaseValue> when invoked 1 time(s)
Parameter 0 for invocation mockMe::increaseValue(<integer:12>) does not match expected value.
Failed asserting that <integer:12> is less than <integer:10>.
