phpunit断言-assertIsCallable
发布时间：2021-10-03 15:36:46编辑：雪饮阅读（）
assertIsCallable断言用来断言一个字符串（做为如方法名）是否可以调用。
类型是 callable。
CallableTest.php：
<?php
use PHPUnit\Framework\TestCase;
function my_callback_function() {
echo 'hello world!';
}
class CallableTest extends TestCase
{
public function testFailure()
{
$this->assertIsCallable(null);
}
public function testSuccess()
{
$this->assertIsCallable('my_callback_function');
}
}
use PHPUnit\Framework\TestCase;
function my_callback_function() {
echo 'hello world!';
}
class CallableTest extends TestCase
{
public function testFailure()
{
$this->assertIsCallable(null);
}
public function testSuccess()
{
$this->assertIsCallable('my_callback_function');
}
}
运行结果如：
