% This is the union runtime testcase. It ensures that values within a 
% union embedded within a struct can be set and read correctly.

% Create new instances of SmallStruct and BigStruct for later use
small = unions.SmallStruct();
small.jill(200);

big = unions.BigStruct();
big.smallstruct(small);
big.jack(300);

% Use SmallStruct then BigStruct to setup EmbeddedUnionTest.
% Ensure values in EmbeddedUnionTest are set correctly for each.
eut = unions.EmbeddedUnionTest();

% First check the SmallStruct in EmbeddedUnionTest
eut.number(1);
eut.uni.small(small);
Jill1 = eut.uni.small.jill;
if (Jill1 ~= 200)
    error('Runtime test1 failed. eut.uni.small.jill=%i' , Jill1)
end

Num1 = eut.number;
if (Num1 ~= 1)
    error('Runtime test2 failed. eut.number=%i' , Num1)
end

% Secondly check the BigStruct in EmbeddedUnionTest
eut.number(2);
eut.uni.big(big);
Jack1 = eut.uni.big.jack;
if (Jack1 ~= 300)
    error('Runtime test3 failed. eut.uni.big.jack=%i' , Jack1)
end

Jill2 = eut.uni.big.smallstruct.jill;
if (Jill2 ~= 200)
    error('Runtime test4 failed. eut.uni.big.smallstruct.jill=%i' , Jill2)
end

Num2 = eut.number;
if (Num2 ~= 2)
    error('Runtime test5 failed. eut.number=%i' , Num2)
end
