Assertions

本附录列出了可用的各种声明方法。

声明方法的静态与非静态使用

PHPUnit 的声明在PHPUnit\Framework\Assert上被执行。PHPUnit\Framework\TestCase继承了PHPUnit\Framework\Assert

声明方法是经过声明的static和可以从任何环境中调用PHPUnit\Framework\Assert::assertTrue(),例如,使用$this->assertTrue()或者self::assertTrue(),例如,在扩展PHPUnit\Framework\TestCase的类中。

实际上,当你(手动)包含 PHPUnit 附带的src/Framework/Assert/Functions.php源代码文件时,甚至可以assertTrue()在任何上下文中使用全局函数包装器(包括扩展的类PHPUnit\Framework\TestCase)。

一个常见的问题,特别是来自 PHPUnit 的开发者的一个常见问题是,是否使用$this->assertTrue()或者self::assertTrue()是调用声明的“正确方式”。简短的回答是:没有正确的方法。而且也没有错误的方式。这是个人喜好的问题。

对于大多数人来说,使用$this->assertTrue()是“感觉不错”,因为测试方法是在测试对象上调用的。声明static声明方法的事实允许(重新)在测试对象的范围之外使用它们。最后,全局函数包装允许开发人员输入更少的字符(assertTrue()而不是$this->assertTrue()self::assertTrue())。

assertArrayHasKey()

assertArrayHasKey(mixed $key, array $array[, string $message = ''])

如果 $array没有$key,报告由$message识别的错误。

assertArrayNotHasKey() 是这个声明的反面,并采用相同的论点。

例 A.1:使用 assertArrayHasKey()

<?php
use PHPUnit\Framework\TestCase;

class ArrayHasKeyTest extends TestCase
{
    public function testFailure()
    {
        $this->assertArrayHasKey('foo', ['bar' => 'baz']);
    }
}
?>

assertClassHasAttribute()

assertClassHasAttribute(string $attributeName, string $className[, string $message = ''])

例 A.2:assertClassHasAttribute()的使用

<?php
use PHPUnit\Framework\TestCase;

class ClassHasAttributeTest extends TestCase
{
    public function testFailure()
    {
        $this->assertClassHasAttribute('foo', stdClass::class);

<?php
use PHPUnit\Framework\TestCase;

class ArraySubsetTest extends TestCase
{
    public function testFailure()
    {
        $this->assertArraySubset(['config' => ['key-a', 'key-b']], ['config' => ['key-a']]);
