Provides combinatorial test data for a test method written with xUnit and MSTest.

This library is designed to simplify the process of generating combinatorial test data for test methods. Combinatorial testing is a technique that involves testing all possible combinations of input values to ensure comprehensive test coverage.

There are 2 different NuGet packages for xUnit and MSTest. You can install the one that fits your testing framework.

• package for xUnit: SolidCode.CombinatorialTests.XUnit
• package for MSTest: SolidCode.CombinatorialTests.MSTest

For example, you can install the SolidCode.CombinatorialTests.XUnit library using the following command:

dotnet add package SolidCode.CombinatorialTests.XUnit

or via NuGet Package Manager in Visual Studio:

PM> Install-Package SolidCode.CombinatorialTests.XUnit

Usage is the same for xUnit and MSTest.

• Add the [CombinatorialData] attribute to the test method that has parameters to make it a combinatorial test method.
• Specify a set of values for each parameter, or use the default set where supported and appropriate:
  • There is no need to specify anything to use the default set of values for supported types (see the list of supported types below).
  • Use the values attribute to specify a set of values if the type has no default set of values, or to provide your own set (see the list of available attributes below).

• [CombinatorialValues(params object?[] values)] - Specifies a set of values for a parameter in a combinatorial test.
• [CombinatorialRangeValues<TNumber>(TNumber start, TNumber max, TNumber step)] - Specifies a set of range-based values for a parameter in a combinatorial test.

NOTE: The .NET Standard 2.0 build implements a non-generic, limited version of this attribute.

• [CombinatorialMemberValues(Type sourceType, string memberName)] - Specifies a set of values for a parameter in a combinatorial test generated by the member of the specified type. If the sourceType is not specified, the type of the current test class is used.

[CombinatorialData]
public async Task SomeTestAsync(
    [CombinatorialValues(7, 42, 255)]
    uint id,
    
    bool isActive,
        
    [CombinatorialMemberValues(memberName: nameof(_raitingValues))]
    Raiting rating,

    [CombinatorialRange<uint>(start: 1, end: 10, step: 2)] 
    uint referenceId,
    
    [CombinatorialRangeValues("comment 1", "comment 2", "comment 3")]
    string comment)
{
    // Test method body
}
