Overview

The DataSetGenerator is a static utility class that provides syntactically convenient methods to generate test data sets lists based on common test data scenarios. It simplifies the creation of DataSet objects for parameterized testing.

Namespace: Unicorn.Taf.Core.Utility

Usage Examples

Single Value Data Sets

// Generate a data set from a list of values
private static List<DataSet> TestData() => 
    DataSetGenerator.FromItems(10, 20, 30, 40, 50);

[Test("Single item dataset")]
[TestData(nameof(TestData))]
public void SingleItemDatasetTest(int value)
{
    // Test logic
}

Pairwise Combinations

// Test matrix for login scenarios (pairs Username/Password):
// 
// admin/correct
// admin/wrong
// admin/empty
// user/correct
// user/wrong
// user/empty
// guest/correct
// guest/wrong
// guest/empty
private static List<DataSet> LoginTestData() => 
    DataSetGenerator.CombinationOf(
        new[] { "admin", "user", "guest" }, // logins
        new[] { "correct", "wrong", "empty" } // passwords
    );

[Test("Pairwise combination item dataset")]
[TestData(nameof(LoginTestData))]
public void PairwiseCombinationsTest(string username, string password)
{
    // Test login with different combinations
}

Three-Way Combinations

// Test matrix for Three-Way Combinations (pairs: country / tier / device):
// 
// USA / Gold / Desktop
// USA / Silver / Desktop
// ...
// Germany / Basic / Desktop
// Germany / Basic / Mobile
private static List<DataSet> PricingTestData() => 
    DataSetGenerator.CombinationOf(
        new[] { "USA", "UK", "Germany" },      // Countries
        new[] { "Gold", "Silver", "Basic" },   // Membership tiers
        new[] { "Desktop", "Mobile" }           // Device types
    );

[Test("Three-Way Combinations")]
[TestData(nameof(PricingTestData))]
public void TestPricing(string country, string tier, string device)
{
    // Test pricing logic across multiple dimensions
}
