如何使用 PHPUnit 在模拟类中添加私有属性
我正在尝试测试一个遍历一个类、获取公共属性并用它创建一个对象的函数。非公共属性在输出中被忽略。因此，我模拟将要处理的类并为其添加一些属性。这是我的代码：
class GetSettingsTest extends TestCase
{
public function getExpected() {
return (object) [
"one" => (object) [
"oneOne" => "1.1",
"oneTwo" => "1.2",
"oneThree" => (object) [
"oneThreeOne" => "1.3.1",
"oneThreeTwo" => "1.3.2",
]
],
"two" => (object) [
"twoOne" => "2.1",
"twoTwo" => "2.2",
"twoThree" => (object) [
"twoThreeOne" => "1.3.1",
"twoThreeTwo" => "1.3.2",
]
],
"three" => (object) [
"threeOne" => "3.1",
"threeTwo" => "3.2"
]
// four is not here : it is protected or private.
];
}
public function getSettingsMock() {
$stub = $this->getMockBuilder('FakeSettingsClass')
->disableOriginalConstructor()
->getMock();
$stub->one = (array) [
"oneOne" => "1.1",
"oneTwo" => "1.2",
"oneThree" => (array) [
"oneThreeOne" => "1.3.1",
"oneThreeTwo" => "1.3.2",
]
];
$stub->two = (array) [// provide an array, must return an object
"twoOne" => "2.1",
"twoTwo" => "2.2",
"twoThree" => (object) [// provide an object, must return an object
"twoThreeOne" => "1.3.1",
"twoThreeTwo" => "1.3.2",
]
];
$stub->three = (array) [
"threeOne" => "3.1",
"threeTwo" => "3.2"
];
}
该函数与 var_dump 配合使用效果很好，它会按预期忽略非公开值。该测试在没有非公共部分的情况下有效，但我想用非公共部分对其进行测试。我不知道如何测试 PhHPUnit 中的非公开部分。可能是通过在 getSettingMock 函数中设置一个受保护的值，但我该怎么做呢？

这是一个基于 xmike 的评论和此处的 Phpunit 文档的解决方案：https ://phpunit.readthedocs.io/en/9.0/fixtures.html 。像这样制作一个夹具类：class GetSettingsFixture{ public array $one = [ "oneOne" => "1.1", "oneTwo" => "1.2", "oneThree" => [ "oneThreeOne" => "1.3.1", "oneThreeTwo" => "1.3.2", ] ]; public array $two = [ "twoOne" => "2.1", "twoTwo" => "2.2", "twoThree" => [ "twoThreeOne" => "1.3.1", "twoThreeTwo" => "1.3.2", ] ]; public array $three = [ "threeOne" => "3.1", "threeTwo" => "3.2" ]; public string $four = "a string"; private array $five = [ // this should be ignored in the output. "fiveOne" => "5.1", "fiveTwo" => "5.2" ]; protected array $six = [ // this should be ignored in the output. "sixOne" => "6.1", "sixTwo" => "6.2" ]; public function testFunction() { // this should be ignored in the output. return "something"; }}这个测试通过：class GetSettingsTest extends TestCase{ private GetSettingsFixture $given; public function setUp(): void { // this function is executed before test. $this->given = new GetSettingsFixture(); // this call the fixture class. } public function tearDown(): void { // this function is executed after the test. unset($this->given); } public function getExpected() { return (object) [ "one" => (object) [ "oneOne" => "1.1", "oneTwo" => "1.2", "oneThree" => (object) [ "oneThreeOne" => "1.3.1", "oneThreeTwo" => "1.3.2", ] ], "two" => (object) [ "twoOne" => "2.1", "twoTwo" => "2.2", "twoThree" => (object) [ "twoThreeOne" => "1.3.1", "twoThreeTwo" => "1.3.2", ] ], "three" => (object) [ "threeOne" => "3.1", "threeTwo" => "3.2" ], "four" => "a string" // five, six are not here : it is protected or private. // testFunction is hot here too, it's not a property. ]; } public function testGetSettings() { $expected = $this->getExpected(); $getSettings = new GetSettings($this->given); $value = $getSettings->getSettings(); $this->assertEquals($expected, $value); }}
