SolidCode.CombinatorialTests.XUnit 1.1.0

SolidCode.CombinatorialTests

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

Description

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.

Installation

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

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).

Supported attributes for specifying sets of values

• [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.

Example

[TestMethod]
[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
}
