Php – File Upload and Unit Testing with Zend Framework

filephpuploadzend-framework

How can one best test a controller action which receives a file upload using Zend_Test_PHPUnit_ControllerTestCase?

Ideally, $this->getRequest()->setPost() would take a filename in the data array, but this does not seem to be supported.

I would be willing at this stage to bootstrap/run my application on the command line and create a request object to pass to the front controller. This would bypass Zend_Test_PHPUnit_ControllerTestCase, but I could subsequently check that the file was uploaded properly through a subsequent $this->dispatch('/some/url') in the ControllerTestCase. However, I am also stumped as to how to get a file into the request object using this method.

The only thing I can think to try right now is to bring up an HTTP server via the command line which points to the app (APPLICATION_ENV='testing') and do a file upload via Zend's Http Client or CURL or something. That doesn't strike me as very elegant.

Anyone else had to deal with this issue?

Thanks!

I would recommend taking a look at the unit tests from the Zend_File_Transfer component. They will be able to offer some insight into this.

Basically, you can manipulate the $_FILES superglobal directly in the setUp() of your unit tests. Next, use mock objects for any external sort of service, otherwise you're not truly unit testing, but integration testing.

I would not worry about testing the actual process of uploading the file. That's the realm of the webserver and the language; what is important is you properly test what you do with a (or no) received file.

But, this all depends on how you are handling your file uploads right now. If you provided some more details on how you handle your file uploads, I may be able to offer more suggestions.

Python – Writing a list to a file with Python

You can use a loop:

with open('your_file.txt', 'w') as f:
    for item in my_list:
        f.write("%s\n" % item)

In Python 2, you can also use

with open('your_file.txt', 'w') as f:
    for item in my_list:
        print >> f, item

If you're keen on a single function call, at least remove the square brackets [], so that the strings to be printed get made one at a time (a genexp rather than a listcomp) -- no reason to take up all the memory required to materialize the whole list of strings.

R – dojo file upload using zend framework problem

dojo.io.iframe.send requires the response data to be wrapped in a TEXTAREA tag. This is the only/easiest cross browser way to successfully access and load the response data, and is a requirement. It looks like you are sending plain JSON back from the action.

You can also adjust your handleAs to be "json" and skip the intermediate dojo.fromJson(data) call, it will be passed to you as a JSON object (provided the response is wrapped in the aforementioned TEXTAREA)
