there's a way to tell Nunit to make a test only if another test passed?

Hi,
I'm new to testing
For example I have a test (test1) that test if getFoo() return something and i have a more complex test (test2) that use one or more time getFoo()
I want the test2 to not start if test1 fails or at least to fail automatically without start testing.

I searched the documentation on Nunit for some attribute like [Require(someothertest)] but i couldn't find anything.


Sorry for my broken english, hope the question is understandable

I'm not doing this

test1(){
    //some test code here
    test2();
}

but I'm doing this

test1(){
    Assert(obj.getFoo()>0);
}
test2(){
    int testValue=obj.getFoo();
    Assert(obj.doSomething(testValue)>=0);
}

this is just an example
but as can you see test2 use obj.getFoo(), so if test1 fails i know getFoo() don't work correctly but getFoo may return a value that make test2 pass anyway, so I want that if test1 fails, test2 must not be tested or must automatically fail since it's not an attendible test

I hope i explained myself a little better :)
