Expect random number but everytime is the same with Nunit

       [Test]
        [Repeat(10)]
        [AutoData]
        public void TestIt(int a,int b)
        {
            Assert.Positive(a + b);
        }

I use repeat attribute to let the method run 10 times,and I expect each time both a and b have different values but I got the same value 10 times.

thank you for you suggestion,I’ll have a try

to increase the randomness of test.

Well, it’s more about the desirable behavior, rather than explanation why the current behavior is incorrect 😉

If you wish, you could easily implement your own AutoData attribute that will have e.g. Repeat property. Use the existing implementation as a base.

Please let me know if you need my further assistance.
