Surity.BepInEx 2.0.0

Surity

Unit-testing framework for Unity mods.

Writing tests

using Surity;

// Only test classes with Only = true are run
// Test classes with Skip = true are skipped
[TestClass(Only = false, Skip = false)]
public class MyTests
{
	// BeforeAll, AfterAll, BeforeEach and AfterEach can be inherited
	[BeforeAll]
	public void SetUp()
	{
		// Ran before all tests in this class
	}

	[AfterAll]
	public void TearDown()
	{
		// Ran after all tests in this class
	}

	[BeforeEach]
	public void TestSetUp()
	{
		// Ran before each test in this class
	}

	[AfterEach]
	public void TestTearDown()
	{
		// Ran after each test in this class
	}

	// Across all test classes, only tests with Only = true are run
	// Tests with Skip = true are skipped
	[Test(Only = false, Skip = false)]
	public void TestSomething()
	{
		// Throw an error to fail. Use your favourite assertion library.
	}
}

Running tests

Tests must be run inside the game if they depend on the Unity runtime.

If you use the BepInEx modding framework, you can add the Surity.BepInEx NuGet package to your test project. The package contains a BepInEx plugin which makes sure all loaded Surity tests are ran only once. The plugin only runs tests if the game was started with the Surity CLI program.

Refer to Surity.BepInEx.cs on how to invoke the test runner manually. Add the Surity.Core NuGet package to your test project if you don't need Surity.BepInEx.

Using Surity CLI

Run tests with the standalone Surity.exe executable or by installing the dotnet tool:

$ dotnet tool install Surity.CLI
$ dotnet surity <path-to-game-exe> [options] [-- arguments]

The program runs the game in batchmode and listens for test results.

Any arguments after -- are passed to the game. For example in

$ dotnet surity <path-to-game-exe> -- -nolog

the -nolog argument is passed to the game executable.
