TestFountain

.NET Publish Coverage Status

TestFountain is a C# library that provides an attribute for xUnit.Net to generate random test data. It aims to simplify the process of generating diverse and comprehensive test cases by automatically creating random input values for your xUnit.Net tests.

Features

  • Random Data Generation: TestFountain allows you to easily generate random test data for your xUnit.Net tests. By using the FountainDataAttribute, you can annotate your test methods and have them automatically receive randomized input parameters.

  • Customization: You can customize the generated data by specifying the data type, range, length, and other attributes using various options provided by TestFountain.

  • Simplified Test Cases: With TestFountain, you no longer need to manually define and manage multiple test cases. It generates a wide range of test inputs automatically, allowing you to focus on writing assertions and verifying the behavior of your code.

Getting Started

Prerequisites

  • .NET 8.0 or later

Installation

You can install TestFountain via NuGet package manager or by adding a reference to your project file.

Using NuGet Package Manager

  1. Open the NuGet Package Manager Console in Visual Studio.
  2. Execute the following command: 
    Install-Package TestFountain

Adding a Reference

  1. Right-click on your project in Visual Studio.
  2. Select "Manage NuGet Packages."
  3. Search for "TestFountain" and click on "Install."

Usage

To use TestFountain in your xUnit.Net tests, follow these steps:

  1. Annotate your test method with the RandomDataAttribute and specify the desired options:

    [Theory]
[FountainData]
public void MyRandomTestMethod(int randomNumber, string randomString)
{
    // Use the random values for testing
}

    In this example, randomNumber and randomString will be automatically populated with random values each time the test runs.

  2. Customize the generated data by using the available options. For example:

    [Theory]
[FountainData(10)]
public void MyRandomTestMethod(int randomNumber)
{
    // Use the random integer value between 0 and 100 for testing
}

  3. Run your xUnit.Net tests as usual, and TestFountain will generate random test data for your annotated test methods.
