如何优雅地使用 spock 框架写单测
添加 Spock 依赖 <!-- 1.Spock 相关 --> <dependency> <groupId>org.spockframework</groupId> <artifactId>spock-core</artifactId> <version>1.3-groovy-2.4</version> <scope>test</scope> </dependency> <dependency> <groupId>org.spockframework</groupId> <artifactId>spock-spring</artifactId> <version>1.3-groovy-2.4</version> <scope>test</scope> </dependency> <!-- 2.PowerMock 相关--> <dependency> <groupId>org.powermock</groupId> <artifactId>powermock-module-junit4</artifactId> <version>2.0.4</version> <scope>test</scope> </dependency> <dependency> <groupId>org.powermock</groupId> <artifactId>powermock-api-mockito2</artifactId> <version>2.0.4</version> <scope>test</scope> </dependency> 单测 Demo 静态类单测 Demo @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 def "test 测试类"(){ //... then: def exception = thrown(v_expectException) exception.code == v_expectCode exception.message == v_expectMessage // ... } 校验参数 def "test 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 }) // ... } 参考文献 Spock 单元测试框架介绍以及在美团优选的实践
