assertCount()

assertCount()

assertCount($expectedCount, $haystack[, string $message = ''])

當(dāng) $haystack 中的元素數(shù)量不是 $expectedCount 時報告錯誤，錯誤訊息由 $message 指定。

assertNotCount() 是與之相反的斷言，接受相同的參數(shù)。

Example?A.10.?assertCount() 的用法

<?php
class CountTest extends PHPUnit_Framework_TestCase
{
    public function testFailure()
    {
        $this->assertCount(0, array('foo'));
    }
}
?>
