phpunit 测试

Warning “The attribute 'syntaxCheck' is not allowed.”#

报错详情如下

Copy Highlighter-hljs
Warning - The configuration file did not pass validation!
  The following problems have been detected:

  Line 11:
  - Element 'phpunit', attribute 'syntaxCheck': The attribute 'syntaxCheck' is not allowed.

  Test results may not be as expected.

意思就是phpunit下的syntaxCheck这个属性不允许存在（大概是这个意思），把这个属性删掉就可以了，其位置如下：

为什么先进行异常断言然后进行调用呢?#

因为异常发生时代码就终止往下运行了，所以你需要事先告诉测试框架 " 下面的代码可能会发生异常，请帮忙检查是否为我断言的样子”，测试框架就会进行 try catch 操作啦。

Copy Highlighter-hljs
// 检查 $type 参数
public function testGetWeaherWithInvalidType()
{
    $w = new Weather('mock-key');

    // 断言会抛出此异常类
    $this->expectException(InvalidArgumentException::class);

    // 断言异常消息为 'Invalid type value(base/all): foo'
    $this->expectExceptionMessage('Invalid type value(base/all): foo');

    $w->getWeather('深圳', 'foo');

    $this->fail('Failed to assert getWeather throw exception with invalid argument.');

}
