Unit testing with UIWebView

Question

When creating an UIWebView inside an unit test I get EXC_BAD_ACCESS:

-(void)test1 {
    [[UIWebView alloc] initWithFrame:CGRectZero];  // EXC_BAD_ACCESS
}

Is there a special configuration to run units test that involve UIWebView?

I'm using OCUnit/SenTest on XCode 4.2.

I get occasional EXC_BAD_ACCESS when debugging on the simulator, but never when running on the device. I suspect a bug :/ – Polypetalous

I have the same exact problem! I thought it was just me. Maybe you can't test UIWebView? – Colville

Answer 1

Apparently this only happens when unit testing a static library directly. Most likely whatever UIWebView needs is not loaded with an empty test host.

When unit testing an app this doest not occur.

So, is there any way to test using a UIWebView in a static library? I added UIKit to the Build Settings of the static library, but I'm still getting this EXC_BAD_ACCESS any time I try to run the test. – Eliciaelicit

You can create an app target that is just for running your unit tests. Create a new empty application in the same workspace and set this as the Target for the unit test target. I call my app TestRunner.

Can you elaborate a little more on this? This seems like a reasonable solution. But did you mean an empty app within the same project or is there a better way to go about setting this up? – Paba

I added a screenshot that shows where the target is configured. – Gambrill

It was the "empty application" part I didn't quite get. But now that I've got it to work, I realized all you meant was a shell application that has no features (empty methods... etc) that just compiles which then allows itself to be "targeted" by our tests to run on. This totally works and is a viable solution. Thanks! – Paba

Just to follow up here. I got the full test suite to work. Luckily this particular project is open source, and the code/methodology can be found in this repro: github.com/BlueKai/bluekai-ios-sdk/tree/master/sdk – Paba

Doesn't help me. I receive GuardMalloc[UnitTestRunner-16080]: could not allocate new zone: (os/kern) no space available instead of uardMalloc[xctest-16321]: could not allocate new zone: (os/kern) no space available. – Mcphail
