How to test HttpUrlConnection ?

[Gal Ben-Haim]

Robolectric's examples for testing Http connections - http://robolectric.blogspot.co.il/2011/01/how-to-test-http-requests.html

are all about DeafultHttpClient, but Google recommends using HttpUrlConnection instead as the Apache client is deprecated.

how should I test Http connections that use HttpUrlConnection ?

[Jan Berkel]

this is not possible yet. is anybody working on this feature?
i guess it's more complicated because you would need to hook into the system class loader which cannot be done dynamically.

I haven't actually done this in a project, but a quick look around
shows a couple interesting ideas:

- Using Jetty to mock responses:

- Creating mock URLs under test, and stubbing URL.openConnection.

Please keep us updated here if you find a good solution or think it
best to try adding this to robolectric.

have you seen an example for the second idea ?

I'm not sure if this is what you were looking for, but here is how you could use Mockito to test an HttpURLConnection object with Robolectric.

thanks for the example !

for those interested, I ended up injecting a mock HttpUrlConnection to the class under test,

I also used mock InputStream and OutputStream to test for correct posting of data and result handling.
