SpringBoot系列: 单元测试2

由 会有一股神秘感。 提交于 2021-01-06 04:55:47
之前发了SpringBoot 单元测试的博客, https://www.cnblogs.com/harrychinese/p/springboot_unittesting.html , 内容较少, 现在补齐SpringBoot单元测试的主要知识点. 测试有很多种, 有单元测试 、集成测试 、冒烟测试 、回归测试 、端到端测试 、功能测试。 它们作用不同, 但又有所重叠. 1. 单元测试: [责任人: 开发人员]针对 class 级别的测试, 针对一个类, 写一个测试类. 在项目中, class 之间依赖调用是很常见的事情, 如果要测试的 classA, 又调用了classB, 这时候就没有遵守 "在一个class范围内测试", 自然不算单元测试, 应归为集成测试了. 不过这时候, 我们可以使用 mock 技术模拟被依赖的 classB, 这样整个测试又聚焦在classA 自身的功能, 所以又变回为单元测试. 2. 集成测试: [责任人: 开发人员]是单元测试在粒度上更进一步, 测试不同class之间的组合功能. 3. 冒烟测试: 可以理解为预测试, 一旦预测试失败(发现重大bug), 就直接停止测试, 打回给开发人员. 4. 回归测试: 重跑原有测试用例. ===================== spring-boot-starter-test 依赖包括: ==========

Spock mock private variable

由 烈酒焚心 提交于 2021-01-03 09:54:22
问题 I'm wondering how I can mock some private variable in a class with Groovy/Spock. Let's say we have this code: public class Car { private Engine engine; public void drive(){ System.out.println("test"); if (engine.isState()) { // Do something } else { // Do something } } } In Mockito I can write: @Mock private Engine engine; @InjectMocks private Car car = new Car(); @Test public void drive() { when(engine.isState()).thenReturn(true); car.drive(); } But I don't know how to do the same in Spock.
