+
+## 单测 Demo
+
+### 静态类单测 Demo
+
+```groovy
+@RunWith(PowerMockRunner.class)
+@PowerMockRunnerDelegate(Sputnik.class) // 交给 spock 代理执行
+@PrepareForTest([静态类.class])
+@SuppressStaticInitializationFor(["静态类全名"]) // 限制静态类里的静态代码块初始化
+class StaticMethodSpec extends Specification {
+
+    def service = Mock(UserService)
+
+    def controller = new UserController(userService: service)
+
+    void setup() {
+        // Mock静态类
+        PowerMockito.mockStatic(静态类.class)
+    }
+
+    @Unroll
+    def "测试类名 #desc"() {
+        given: "给定条件"
+        def user = service.getById(_ as Integer) >> [new User(name: "Alice", age: 12), null]
+        def map = [k1:v1, k2:v2]
+        def list = [1,2,3]
+
+        and: "mock静态方法返回值"
+        PowerMockito.when(静态类.静态方法(Mockito.any())).thenReturn(自己想要的返回值)
+
+        when: "调用时"
+        def res = controller.getById(v_id)
+
+
+        then: "比较"
+        res != exp
+        // 或者 
+        with(res){
+            name == v_name
+            age == v_age
+        }
+
+        where "数据格式"
+        desc      | v_id || exp
+        "success" | 1    || new User(name: "Alice", age:12)
+        "fail"    | -1   || null
+    }
+}
+```
+
+### 捕获异常
+
+```groovy
+def "测试类"(){
+    //...
+
+    then:
+    def exception = thrown(v_expectException)
+    exception.code == v_expectCode
+    exception.message == v_expectMessage
+
+    // ...
+}
+```
+
+### 校验参数
+
+```groovy
+def "测试类"(){
+    //...
+
+    then:
+    1 * 某类.某方法({
+        it.某属性1 == 属性1
+        it.某属性2 == 属性2
+    })
+
+    // ...
+}
+```
