GHUnit test with async HTTP get action

Question

I want to test async HTTP get action.

@interface Sender : NSObject<NSURLConnectionDataDelegate, NSURLConnectionDelegate>
{
    NSMutableData       *buffer;
    NSString            *_html
}

- (void)getHtml;

@end

@implementation Sender

- (void)getHtml
{
    NSString *urlstr = @"http://www.yahoo.co.jp";
    NSURL *url = [NSURL URLWithString:urlstr];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    NSURLConnection *conn = [NSURLConnection connectionWithRequest:request delegate:self];
    if (conn) {
        buffer = [NSMutableData data];
    } else {
        // error handling
    }
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [buffer appendData:data];
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSLog(@"Succeed!! Received %d bytes of data", [buffer length]);
    _html = [[NSString alloc] initWithData:buffer encoding:NSUTF8StringEncoding];
    NSLog(@"%@", _html);
}

@end

I have to let _html property ?

#import "SenderTestCase.h"
#import "Sender.h"

@implementation SenderTestCase

- (void)setUpClass
{
    sender = [[Sender alloc] init];
}

- (void)testGetHtml
{
    [self prepare];
    [sender getHtml];
    [self performSelector:@selector(_succeedGetHtml) withObject:nil afterDelay:3.0];
    [self waitForStatus:kGHUnitWaitStatusSuccess timeout:4.0];
}

- (void)_succeedGetHtml
{
    if (sender.html != nil) {
        [self notify:kGHUnitWaitStatusSuccess forSelector:@selector(testGetHtml)];
    };
}

@end

If there is more nice way, please tell me. Thank you for your kindness.

You are doing it correct.

If you want your code to be nicer (and shorter), consider using AFNetworking and the use of blocks.

I have a GHUnit async test example, which shows nicely within 1 method.
