PHPUnit9.0 斷言-assertEquals()

assertEquals(mixed $expected, mixed $actual[, string $message = ''])

PHPUnit9.0 斷言集合

當(dāng)兩個(gè)變量 ?$expected? 和 ?$actual? 不相等時(shí)報(bào)告錯(cuò)誤，錯(cuò)誤訊息由 ?$message? 指定。
?assertNotEquals()? 是與之相反的斷言，接受相同的參數(shù)。
示例 1.14 assertEquals() 的用法

<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;

final class EqualsTest extends TestCase
{
    public function testFailure(): void
    {
        $this->assertEquals(1, 0);
    }

    public function testFailure2(): void
    {
        $this->assertEquals('bar', 'baz');
    }

    public function testFailure3(): void
    {
        $this->assertEquals("foo\nbar\nbaz\n", "foo\nbah\nbaz\n");
    }
}

如果 ?$expected? 和 ?$actual? 是某些特定的類型，將使用更加專門(mén)的比較方式。

assertEquals(DOMDocument $expected, DOMDocument $actual[, string $message = ''])

當(dāng)?$expected?和 ?$actual ?這兩個(gè) ?DOMDocument對(duì)象所表示的 XML 文檔對(duì)應(yīng)的無(wú)注釋規(guī)范形式不相同時(shí)報(bào)告錯(cuò)誤，錯(cuò)誤訊息由 ?$message? 指定。
