.andThrow(anException) will not throw the provided anException

[KaIKuxy]

Based on the documentation:

OCMStub([mock someMethod]).andThrow(anException);

When someMethod is invoked the stub will throw anException.

However it seems like a special exception is thrown instead of the provided one, the provided one is wrapped inside the userInfo

Repro

@interface Dummy : NSObject
- (void)method;
- (void)throwException;
@end

@implementation Dummy
- (void)method {
    @try {
        [self throwException];
    } @catch (NSException *exception) {
        NSLog(@"exception %@ %@", exception.name, exception.reason);
    }
}
- (void)throwException { }
@end

@interface DummyTests : XCTestCase
@end
@implementation DummyTests
- (void)testDummy {
    id dummyPartialMock = OCMPartialMock([Dummy new]);
    OCMStub([dummyPartialMock throwException]).andThrow([NSException exceptionWithName:@"name" reason:@"reason" userInfo:nil]);
    [dummyPartialMock method];
}
@end

The printed message will be exception OCMStubbedException Exception stubbed in test instead of exception name reason.

You're reading too much into what's printed. Yes, at some point that exception is thrown in the code you found, but that exception get's caught and unwrapped later: https://github.com/erikdoe/ocmock/blob/7f6e9e9b6c9ffa19a9040860da9f7a1f202b9f4d/Source/OCMock/OCMockObject.m#L388-L403

There's a unit test that shows the correct behaviour: https://github.com/erikdoe/ocmock/blob/7f6e9e9b6c9ffa19a9040860da9f7a1f202b9f4d/Source/OCMockTests/OCMockObjectMacroTests.m#L251-L258

In your dummy, please check what exception is actually thrown.
