使用 Simpletest 进行单元测试的问题

发布于 2024-10-23 11:53:35 字数 533 浏览 3 评论 0原文

我使用 PHP 和 simpletest 进行单元测试。我的测试工作正常，直到我尝试设置 cookie

try{
    setcookie($name,$cookie,$cookie_expires );
}catch Exception($e){
  blah
}

抛出异常，因为 simpletest 已经写出了标头信息，因此我得到以下信息：

意外的 PHP 错误 [无法修改标头信息 - 标头已由（输出从 /tests/simpletest/reporter.php:43 开始）发送] 严重性 [E_WARNING] 在 [blah_code.php 第 280 行]

我已经看到了有关捕获此问题的模糊解释与 $this->expectException(new Exception()); 但没有进一步的文档或示例。有人可以提供一个可行的示例或向我指出文档吗？要明确的是。这不是我生成输出的代码，而是 SimpleTest。

I am using PHP and simpletest for unit testing. My tests work fine until I try and set the cookie

try{
    setcookie($name,$cookie,$cookie_expires );
}catch Exception($e){
  blah
}

The exception is thrown because simpletest has already written out header information so I get the following:

Unexpected PHP error [Cannot modify header information - headers already sent by (output started at /tests/simpletest/reporter.php:43)] severity [E_WARNING] in [blah_code.php line 280]

I've seen vague explanations on catching this with $this->expectException(new Exception()); but no further documentation or examples that work. Could someone provide a working example or point me to documentation? To be clear. This is NOT my code producing the output but rather SimpleTest.

解决这个问题的一种方法是使用输出缓冲。

您可以在 PHP 的配置中（也可能在 .htaccess 中）全局打开它，或者您可以使用 ob_start() 和其相关函数（ob_get_clean()、ob_end_flush() 等）。例如：

ob_start();
// your SimpleTest here.
// your header/ cookie manipulation here.

然后：

ob_end_clean(); // Stop buffering and dump everything (don't echo).
ob_end_flush(); // Stop buffering and echo out the buffer.
ob_get_clean(); // Stop buffering and return everything as a string.

或任何其他相关函数。如果您不这样做，我相信 PHP 会在文件末尾调用 ob_flush() 。

One way to get around this is by using output buffering.

You can turn it on globally in PHP's configuration (and possibly in .htaccess), or you can use ob_start() and its related functions (ob_get_clean(), ob_end_flush(), etc). For example:

ob_start();
// your SimpleTest here.
// your header/ cookie manipulation here.

And then:

ob_end_clean(); // Stop buffering and dump everything (don't echo).
ob_end_flush(); // Stop buffering and echo out the buffer.
ob_get_clean(); // Stop buffering and return everything as a string.

Or any of the other related functions. I believe PHP calls ob_flush() at the end of a file if you don't.
