In my program I have NSTextField bound to an object using the "value"-
Binding.
I would like to test the functionality in a unit-test. I tried using
setStringValue:
of the NSTextField but the bound object is not updated. Do I have to
call some
methods before/after changing the value?
For example:
// setup:
NSTextField* textField = [[NSTextField alloc] initWithFrame:
NSMakeRect(0,0,100,20)];
id person = [Person personWithName: @"foo"]; // person has "name"
NSObjectController* controller = [[NSObjectController alloc]
initWithContent: person];
[textField bind: @"value"
toObject: controller
withKeyPath: @"selection.name"
options: nil]
// try it out:
NSString* newName = @"bar";
[textField setStringValue: newName];
STAssertEqualObjects( [person valueForKey:@"name"], newName, nil);
// this fails
Is there a better way to test controls using bindings?
Thanks in advance,
felix
