As with any kind of development, it’s good practice to add tests to your package. There are three things you must do to set up tests on your package:
可以将测试文件添加到包的 Tests 文件夹的 Editor 和 Runtime 子文件夹中。例如，一个包含测试的简单包可能如下所示：
MyPackage
├── package.json
├── Editor
│ ├── MyPackage.Editor.asmdef
│ └── EditorExample.cs
├── Runtime
│ ├── MyPackage.Runtime.asmdef
│ └── RuntimeExample.cs
└── Tests
├── Editor
│ ├── MyPackage.EditorTests.asmdef
│ └── EditorExampleTest.cs
└── Runtime
├── MyPackage.RuntimeTests.asmdef
└── RuntimeExampleTest.cs
每个子文件夹必须包含一个 .asmdef 文件，该文件提供对 Editor 和 Runtime 程序集的引用。程序集定义文件还提供对测试程序集文件的引用。有关更多信息，请参阅用于测试的程序集定义文件。
可以直接编辑程序集定义文件。需要确保添加以下引用：
| 属性 | 类型 | 描述 |
|---|---|---|
| name | String | 程序集的名称（不含文件扩展名）。 |
| references | 字符串数组 | References to the Editor and Runtime assemblies. Assembly definition files require different references, depending on the test type: - For Editor tests, add a reference to the package’s Editor and Runtime assemblies. - For Runtime tests, add a reference to the package’s Runtime assembly only. |
| optionalUnityReferences | 字符串数组 | This list of Unity references must include "TestAssemblies" to mark the assembly as a test assembly. This adds references to the nunit.framework.dll and UnityEngine.TestRunner.dll libraries to the Assembly Definition. |
| includePlatforms | 字符串数组 | For the Editor test, this list of platforms must include the "Editor" platform. |
提示：还可以在 Inspector 中编辑程序集定义文件。请参阅程序集定义以了解更多信息。
Editor 测试 .asmdef 文件应如下所示：
{
"name": "MyPackage.Editor.Tests",
"references": [
"MyPackage.Editor",
"MyPackage"
],
"optionalUnityReferences": [
"TestAssemblies"
],
"includePlatforms": [
"Editor"
],
"excludePlatforms": []
}
运行时测试 .asmdef 文件应如下所示：
{
"name": "MyPackage.Tests",
"references": [
"MyPackage"
],
"optionalUnityReferences": [
"TestAssemblies"
],
"includePlatforms": [],
"excludePlatforms": []
}
对于嵌入式包，不需要显式启用测试，因为嵌入式包正在开发中。
但是，对于其他类型的依赖项，则需要向项目清单添加 testables 属性，并添加包含待运行测试的包名称。这包括项目的直接依赖项和间接依赖项。例如：
{
"dependencies": {
"com.unity.some-package": "1.0.0",
"com.unity.other-package": "2.0.0",
"com.unity.yet-another-package": "3.0.0",
},
"testables": ["com.unity.some-package", "com.unity.other-package"]
}
This example adds tests for the com.unity.some-package and com.unity.other-package packages in Unity’s Test Framework package.
Note: You might need to import the package again, because the test framework doesn’t always immediately pick up changes to the testables attribute.
