You can generate a file upload in a programmatic manner with e.g. the <a href="http://php.net/curl" rel="noreferrer">curl</a> extension.

Since this requires PHP running under a web server, it's not much of a unit test. Consequently, the best way would be to to use PHPT tests and fill the <a href="http://qa.php.net/phpt_details.php#post_raw_section" rel="noreferrer"><code>--POST_RAW--</code> section</a> with the data.

If you don't know what to put in the <code>--POST_RAW--</code>, try to install the TamperData Firefox extension, do a file submission from Firefox, and copy-paste the data from the right side.

According to the Docs, <a href="http://simpletest.org/en/overview.html" rel="noreferrer">SimpleTest has support for FileUpload testing baked in since version 1.0.1:</a>

<pre><code>File upload testing Can simulate the input type file tag 1.0.1
</code></pre>

I've looked over the examples at their site and would assume you'd use something along the lines of

<pre><code>$this-&gt;get('http://www.example.com/');
$this-&gt;setField('filename', 'local path');
$this-&gt;click('Go');
</code></pre>

to submit the file and then use the regular assertions to check the upload worked as wanted. But that's really just a wild guess, since I am not familiar with SimpleTest and I couldnt find an example at their homepage. You might want to <a href="http://sourceforge.net/mailarchive/forum.php?forum_name=simpletest-support" rel="noreferrer">ask in their support forum though.</a>

But basically, there is not much use testing that a form uploads a file. This is tried and tested browser behavior. Testing the code that handles the upload makes more sense. I dont know how you implemented your FileUpload code, but if I had to implement this, I would get rid of the dependency on the <code>$_FILES</code> array as the first thing. Create a <code>FileRequest</code> class that you can pass the <code>$_FILES</code> array to. Then you can handle the upload from the class. This would allow you to test the functionality without actually uploading a file. Just setup your FileRequest instance accordingly. You could even mock the filesystem with <a href="http://code.google.com/p/bovigo/wiki/vfsStream" rel="noreferrer">vfsStreamWrapper</a>, so you dont even need actual files.

blocks|key|1180998|text|我找到了另一个解决方案。我用测试数据欺骗了$_FILES数组，在tmp/文件夹中创建了虚拟测试文件(该文件夹与我无关，但我尝试使用默认文件夹)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1180999|问题是is_uploaded_file和move_uploaded_file无法处理这种欺骗的项目，因为它们并不是真正通过POST上传的。我做的第一件事是将这些函数包装在我自己的插件的moveUploadedFile和isUploadedFile中，这样我就可以模拟它们并更改它们的返回值。|1181000|最后一件事是在测试类时扩展它，并重写moveUploadedFile以使用rename而不是move_uploaded_file，使用isUploadedFile来使用file_exists而不是is_uploaded_file。|1181001|entityMap^0|L|7|W|4|0|3|G|K|I|1P|4|2K|G|31|E|0|I|G|11|6|1A|I|1V|E|2C|B|2Q|G|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]|$9|X|A|Y|B|C]|$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|11|8|@$9|12|A|13|B|C]|$9|14|A|15|B|C]|$9|16|A|17|B|C]|$9|18|A|19|B|C]|$9|1A|A|1B|B|C]|$9|1C|A|1D|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|1E|8|@]|D|@]|E|$]]]|K|$]]

I've found an alternate solution. I've spoofed the <code>$_FILES</code> array with test data, created dummy test files in the <code>tmp/</code> folder (the folder is irrelevant, but I tried to stick with the default).

The problem was that <code>is_uploaded_file</code> and <code>move_uploaded_file</code> could not work with this spoofed items, because they are not really uploaded through <code>POST</code>.
First thing I did was to wrap those functions inside my own <code>moveUploadedFile</code> and <code>isUploadedFile</code> in my plugin so I can mock them and change their return value.

The last thing was to extends the class when testing it and overwriting <code>moveUploadedFile</code> to use <code>rename</code> instead of <code>move_uploaded_file</code> and <code>isUploadedFile</code> to use <code>file_exists</code> instead of <code>is_uploaded_file</code>.

blocks|key|966775|text|对于单元测试(与功能测试相对)，尝试将一个文件(一个短文本文件)上传到测试页面，以及var_dump($_FILES)和var_dump($_POST)。然后你就知道用什么来填充它们(或者你的mock)了。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|966776|entityMap^0|16|H|1O|G|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

For unit testing (as opposed to functional testing) try uploading a file (a short text file) to a test page, and <code>var_dump($_FILES)</code> and <code>var_dump($_POST)</code>. Then you know what to populate them (or your mocks) with.

I'm using simpleTest to write my PHP tests. I'm writing a file upload plugin and was wondering how I may be testing it.

I would like to check that the file is correctly uploaded, in the right folder, that error are correctly returned when needed, etc.

How do I emulate a file upload (through the $_FILES variable) ? Are there any issues I should be aware of ?

How can I write tests for file upload in PHP?

单元测试

文件系统

服务器

我正在使用simpleTest编写我的PHP测试。我正在写一个文件上传插件，想知道我如何测试它。我想检查文件是否正确上传，是否在正确的文件夹中，是否在需要时正确返回错误，等等。如何模拟文件上传(通过$_FILES变量)？有什么我应该注意的问题吗？
