PHPUnit9.0 断言-assertCount()
2022-03-24 10:18 更新
assertCount($expectedCount, $haystack[, string $message = ''])
PHPUnit9.0 断言集合当 $haystack
中的元素数量不是 $expectedCount
时报告错误,错误讯息由 $message
指定。
assertNotCount()
是与之相反的断言,接受相同的参数。
示例 1.9 assertCount() 的用法
<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;
final class CountTest extends TestCase
{
public function testFailure(): void
{
$this->assertCount(0, ['foo']);
}
}
$ phpunit CountTest
