Question

My project generates few values(equal partitioning method) for each data types by getting the Minimum and Maximum values. I am doing this generating values for functional testing, I am actually passing this values to nunit partner, max amd min are applicable to int, float, double etc., these values are test data .

Initially I generated for basic data types like int, float, double, string etc.

Now I need to support data types like DataSet, HashTable and other Collections.

public DataSet MySampleMethod(int param1, string param2, Hashtable ht) 

For testing this function I can pass values for int and string but how will I pass test data for ht or how is test data generated for hash table?

Answer 1

First – I always seed my random values for unit tests, so that hey are repeatable – however, something like (using Dictionary<,> instead of HashTable, but equivalent):

        Random rand = new Random(123456); // note seed         Dictionary<int, double> lookup = new Dictionary<int, double>();         for (int i = 0; i < 5000; i++)         {             lookup[rand.Next(100000)] = rand.NextDouble();         }
