依赖注入
@Mocked
- 作用范围
@Mocked 可修饰类/接口；影响类的所有实例。 - 功能
mocked对象方法（包含静态方法)返回默认值：即如果返回类型为原始类型(short,int,float,double,long)就返回0，如果返回类型为String就返回null，如果返回类型是其它引用类型，则返回这个引用类型的Mocked对象 - 使用场景
比如在分布式系统中，我们的测试程序依赖某个接口的实例是在远程服务器端时，我们在本地构建是非常困难的，此时就交给@Mocked，就太轻松啦
@Tested&@Injectable
- 作用范围
@Tested表示被测试对象；只影响类的一个实例 - 功能
若@Tested的构造函数有参数，则JMockit通过在测试属性&测试参数中查找@Injectable修饰的Mocked对象注入@Tested对象的构造函数来实例化，不然，则用无参构造函数来实例化。除了构造函数的注入，JMockit还会通过属性查找的方式，把@Injectable对象注入到@Tested对象中。 注入的匹配规则：先类型，再名称(构造函数参数名，类的属性名)。若找到多个可以注入的@Injectable，则选择最优先定义的@Injectable对象 - 功能
当我们需要手工管理被测试类的依赖时,就需要用到@Tested & @Injectable
@Capturing
- 作用范围
子类/实现类 - 功能
@Capturing主要用于子类/实现类的Mock - 功能
只知道父类或接口时，但我们需要控制它所有子类的行为时，子类可能有多个实现（可能有人工写的，也可能是AOP代理自动生成时）。就用@Capturing
Expectations
- 作用范围
通过引用外部类的Mock对象(@Injectabe,@Mocked,@Capturing)来录制；通过构建函数注入类/对象来录制 - 功能
录制类/对象的调用，返回值是什么 - 功能
用来对mock对象的录制结果做限制
MockUp & @Mock
- 作用范围
对某个类进行局部mock - 功能
进行局部方法模拟，不能mock接口 只会影响到部分方法，其余方法正常访问 - 功能
MockUp & @Mock比较适合于一个项目中，用于对一些通用类的Mock，以减少大量重复的new Exceptations{{}}代码
Verifications
- 作用范围
对某个方法实现验证 - 功能
验证Mock对象（即@Moked/@Injectable@Capturing修饰的或传入Expectation构造函数的对象)有没有调用过某方法，调用了多少次 - 功能
测试程序关心类的某个方法有没有调用，调用多少次，你可以使用new Verifications() {{}}验证代码块

}数据库内存替代方案-H2
主要针对 mybatis 和 H2 内存数据库实现对数据库的单元测试
单元测试中对 service 和 dao 层测试时，主要存在以下问题：
- 需要启动完整的spring容器
- 依赖中间件过多，测试配置文件需要编写与 DAO 层测试无意义的配置
- 需要搭建各种环境(mysql,redis,kafka等）
- 每个测试用例都对应一套SQL,并且会对本地的数据库造成影响
针对以上问题，我们在单元测试中解决以上问题：
- 针对DAO层单元测试(service层会互相引用和循环依赖)
- 不启动完整容器，不需要多余配置
- 使用内存数据库，不需要搭建其他环境，保证测试隔离
- 单个测试用例对应自己的SQL
h2 内存数据库的优势
- 占用空间小
- 即用即消
- 读写速度很快
- 支持嵌入模式使用数据库，在项目中只需导入依赖就可以使用
- 不会污染各环境的正式数据库
具体步骤：
1. dao 测试工具类
/**

*/
public class BaseDaoTestUtil {
private static final Logger logger = LoggerFactory.getLogger(BaseDaoTestUtil.class);
public final static String DRIVER = "org.h2.Driver";
public final static String DB_URL = "jdbc:h2:mem:test;MODE=MySql;DB_CLOSE_DELAY=-1";
public final static String USER = "root";
public final static String PASSWORD = "123456";
/**

private static Configuration configuration;
private static final ThreadLocal<SqlSession> localSessions = new ThreadLocal<>();
static {
try {
// 定义 configuration

// 不使用全局缓存
configuration.setCacheEnabled(false);
configuration.setLazyLoadingEnabled(false);
configuration.setAggressiveLazyLoading(true);
configuration.setDefaultStatementTimeout(20);
} catch (Exception e) {
logger.error("实例化 configuration 失败！", e);
}
}
/**

*
* @return

public static SqlSession getSqlSession() {
SqlSession sqlSession = localSessions.get();
if (sqlSession == null) {
//设置数据库链接
UnpooledDataSource dataSource = new UnpooledDataSource();
dataSource.setDriver(DRIVER);
dataSource.setUrl(DB_URL);
dataSource.setUsername(USER);
dataSource.setPassword(PASSWORD);
//设置事务,使用 JDBC 的事务管理方式(测试设置事务不提交false)
Transaction transaction = new JdbcTransaction(dataSource, TransactionIsolationLevel.READ_UNCOMMITTED, false);
//设置执行
Executor executor = configuration.newExecutor(transaction);
//直接实例化一个默认的sqlSession
//是做单元测试，那么没必要通过SqlSessionFactoryBuilder构造SqlSessionFactory,再来获取SqlSession
sqlSession = new DefaultSqlSession(configuration, executor, false);
localSessions.set(sqlSession);
}
return sqlSession;
}

public static <T> T getMapper(String mapperXmlPath, Class<T> mapperClass) {
try {

Resource mapperResource = new ClassPathResource(mapperXmlPath);
XMLMapperBuilder xmlMapperBuilder = new XMLMapperBuilder(mapperResource.getInputStream(), configuration, mapperResource.toString(), configuration.getSqlFragments());
xmlMapperBuilder.parse();
// 返回 mapper 实例
return getSqlSession().getMapper(mapperClass);
} catch (Exception e) {
logger.error("实例化 mapper 失败！mapperXmlPath >>>>>{}", mapperXmlPath, e);
}
return null;

public static void closeSqlSession() {
SqlSession sqlSession = localSessions.get();
if (sqlSession != null) {
sqlSession.close();
localSessions.remove();
}
logger.info("#Close Session successfully");
}
}2. Resources 目录下放置初始化 SQL 脚本
3. 使用工具类进行 dao 测试，以 TemplateCiDao 为例
/**

* @author yongzhe.dong

*/
class TemplateCiDaoTest {
private static SqlSession sqlSession;
private static TemplateCiMapper templateCiMapper;

static void setUpAll() throws IOException {
// 获取 mapper 实例
templateCiMapper = BaseDaoTestUtil.getMapper("mapper/ci/TemplateCiMapper.xml", TemplateCiMapper.class);
sqlSession = BaseDaoTestUtil.getSqlSession();
Connection connection = sqlSession.getConnection();
// 创建 ScriptRunner，读取 SQL 脚本并执行
ScriptRunner runner = new ScriptRunner(connection);
runner.setErrorLogWriter(null);
runner.setLogWriter(null);
// 执行初始化SQL脚本
runner.runScript(Resources.getResourceAsReader("sql/TemplateCi.sql"));
}
@AfterEach
void teardown() {
sqlSession.commit();
}
@AfterAll
static void teardownAll() {
BaseDaoTestUtil.closeSqlSession();
}
@DisplayName("Test insert and query list")
@Test
void testSelectTemplateCiList() {
Long templateId = 1L;
TemplateCi templateCi = DataProvider.anyObject(TemplateCi.class);
templateCi.setId(templateId);
templateCi.setNeedSubmodules(1);
templateCi.setNeedBranch(1);
templateCi.setCmdbServiceName(1);
// 插入
templateCiMapper.insertTemplateCi(templateCi);
// 查询
List<TemplateCi> templateCis = templateCiMapper.selectTemplateCiList(new TemplateCi());
// 断言
Assertions.assertThat(templateCis)
.isNotEmpty().containsExactly(templateCi);
}
}造数据
Fastjunit 包的工具方法
1. Bean对象
BeanObject beanObject = .anyObject(BeanObject.class);
System.out.println("anyObject：" + JsonUtils.writeJsonStr(beanObject));2. 数组
BeanObject[] beanObjectArray = DataProvider.anyArray(BeanObject.class);
System.out.println("数组：" + JsonUtils.writeJsonStr(beanObjectArray));3. 列表
BeanObject[] beanObjectArray = DataProvider.anyArray(BeanObject.class);
System.out.println("数组：" + JsonUtils.writeJsonStr(beanObjectArray));CRUD 贫血操作业务的单测
业务中很多是普通的增删改查，针对这种场景，你一个个方法去测意义不大，为了覆盖率能达标且用例是有意义的，建议直接从 controler api 入口到 mapper 数据库直接单测执行下去。这种严格算来是属于集成测试的，等到后续如果业务变复杂了，可以再拆开测试。单测代码最好不要启动 spring 容器，如果必要的话就要尽可能小范围的加载 spring 相关的东西，千万不用启动整个 spring 容器，这样会非常慢。

}核心复杂业务 service 单测
复杂业务的一大困惑点是 一大堆需要 mock 的上下文，可以通过以下方式梳理：
- 了解 mock 跟 mockup 的区别
- 从整个业务去考虑单测的上下文，而不是每个方法各自考虑
- 上下文的封装抽取，不要杂在用例里面。
- mock 跟 mockup 的区别
在之前的分享里面有谈单替身对象根据场景是有很多区分的：单元测试 - 交流分享
在 jmockit 的语法里面：mock 的作用是替换，mockup 的作用是伪装（不是简单的给你代替了，而是要伪装成类似本来的你）
- 从整个业务去考虑单测的上下文
复杂业务里面需要 mock 的上下文很多，如果每个用例单独进行，重复 mock 的对象会有很多。可以全局考虑，统一 mock。 - 上下文封装抽取

}并行测试
依赖junit5.3的并行测试
默认情况下，junit测试是在一个线程中串行执行的，从5.3开始支持并行测试。
首先需要在resources创建配置文件junit-platform.properties，添加配置如下参数：
#是否允许存在并发测试
junit.jupiter.execution.parallel.enabled = true
#设置单元测试默认执行方式：concurrent并发执行，same_thread 串行执行，默认same_thread
unit.jupiter.execution.parallel.mode.default = concurrent
#设置单元测试类执行方式：concurrent并发执行，same_thread 串行执行，
#不设置时根据junit.jupiter.execution.parallel.mode.default同值
junit.jupiter.execution.parallel.mode.classes.default = same_thread配置的默认执行模式会作用于测试树上的每个节点，但是有几个需要主要的例外。
首先就是针对于测试声明周期的配置（默认是方法级别的）如果设置为类级别，则必须保证测试类是线程安全的，另外对于设置测试方法的执行顺序的话，这个与并发测试是互相矛盾的。
在以上这两种情况下，必须明确在测试类或方法上面添加注解@Execution(CONCURRENT),否则也不会按照并发模式进行测试的。
采用以上的模式，所有的测试类和测试方法都是并发来执行的。
单元测试类
@Slf4j
public class Service1Test {
@Test
public void method1(){
log.info("执行测试：Service1Test.method1,线程："+Thread.currentThread().getName());
//empExtService.initEmpExtList();
Thread.sleep(3000)
Assert.assertTrue(true);
}
@Test
public void method2(){
log.info("执行测试：Service1Test.method2,线程："+Thread.currentThread().getName());
//empExtService.initEmpExtList();
Assert.assertTrue(true);
}
}当不开启并行测试时，执行结果为：
。。。.method1(Service1Test.java:26) - 执行测试：Service1Test.method1,线程：main
。。。.method2(Service1Test.java:33) - 执行测试：Service1Test.method2,线程：main当开启后，方法并行时执行结果：(可看到执行的线程不是同个)
method1(Service1Test.java:26) - 执行测试：Service1Test.method1,线程：ForkJoinPool-1-worker-2
method2(Service1Test.java:33) - 执行测试：Service1Test.method2,线程：ForkJoinPool-1-worker-12. 依赖surefire插件的并行测试
Maven-surefire-plugin 是一个用于mvn 生命周期的测试阶段的插件，可以通过一些参数设置方便的在junit下对测试阶段进行自定义。
Maven运行测试用例时，是通过调用maven的surefire插件并fork一个子进程来执行用例的。
在surefire版本2.14之前使用forkMode控制多进程，现在使用forkCount控制。
在surefire插件配置<configuration>中添加如下配置：
需要注意的是，这边是以测试类为执行单位,并发执行。
（目前的执行环境：jmockit：1.46；junit-jupiter-api：5.4.0；junit-jupiter-engine：5.4.0；maven-surefire-plugin：3.0.0-M5）
<!--forkCount启动的fork的进程数 -->
<forkCount>3</forkCount>
<!--表示一个测试进程执行完了之后是杀掉还是重用来继续执行后续的测试 -->
<reuseForks>true</reuseForks>参数化测试
和Junit4相比，Junit5框架更多在向测试平台演进。其核心组成也从以前的一个Junit的jar包更换成由多个模块组成。
- junit-jupiter-engine: Junit的核心测试引擎
- junit-jupiter-params: 编写参数化测试所需要的依赖包
- junit-platform-launcher: 从IDE(InteliJ/Eclipses)等运行时所需要的启动器
参数源：
如果待测试的输入和输出是一组数据： 可以把测试数据组织起来 用不同的测试数据调用相同的测试方法
参数化测试和普通测试稍微不同的地方在于，一个测试方法需要接收至少一个参数，然后，传入一组参数反复运行。
JUnit5提供了一个@ParameterizedTest注解，用来进行参数化测试。
假设我们想对Math.abs()进行测试，先用一组正数进行测试：
@ParameterizedTest
@ValueSource(ints = { 0, 1, 5, 100 })
void testAbs(int x) {
assertEquals(x, Math.abs(x));
}再用一组负数进行测试：
@ParameterizedTest
@ValueSource(ints = { -1, -5, -100 })
void testAbsNegative(int x) {
assertEquals(-x, Math.abs(x));
}参数化测试的注解是@ParameterizedTest，而不是普通的@Test。
假设我们自己编写了一个StringUtils.capitalize()方法，它会把字符串的第一个字母变为大写，后续字母变为小写：
public class StringUtils {
public static String capitalize(String s) {
if (s.length() == 0) {
return s;
}
return Character.toUpperCase(s.charAt(0)) + s.substring(1).toLowerCase();
}
}要用参数化测试的方法来测试，我们不但要给出输入，还要给出预期输出。因此，测试方法至少需要接收两个参数：
@ParameterizedTest
void testCapitalize(String input, String result) {
assertEquals(result, StringUtils.capitalize(input));
}现在问题来了：参数如何传入？
最简单的方法是通过 @MethodSource注解，它允许我们编写一个同名的静态方法来提供测试参数：
@ParameterizedTest
@MethodSource()
void testCapitalize(String input, String result) {
assertEquals(result, StringUtils.capitalize(input));
}
static List<Arguments> testCapitalize() {
return List.of( // arguments:
Arguments.arguments("abc", "Abc"), //
Arguments.arguments("APPLE", "Apple"), //
Arguments.arguments("gooD", "Good"));
}上面的代码很容易理解：静态方法testCapitalize()返回了一组测试参数，每个参数都包含两个String，正好作为测试方法的两个参数传入。
参数转换
Junit5 支持对提供给 @ParameterizedTest 的参数进行扩展的原始转换。
例如，使用 @ValueSource(ints ={1,2,3}) 注释的参数化测试可以声明为不仅接受int类型的参数，而且接受long、float或double类型的参数。
例如，如果 @ParameterizedTest 声明类型TimeUnit的参数，而声明的源提供的实际类型是字符串，
则该字符串将自动转换为相应的 TimeUnit enum常量。
@ParameterizedTest
@ValueSource(strings = "SECONDS")
void testWithImplicitArgumentConversion(TimeUnit argument) {
assertNotNull(argument.name());
}显式转换
与使用隐式参数转换不同，您可以使用@ConvertWith注释显式地指定一个ArgumentConverter来使用，如下面的示例所示。
@ParameterizedTest
@EnumSource(TimeUnit.class)
void testWithExplicitArgumentConversion(
@ConvertWith(ToStringArgumentConverter.class) String argument) {
assertNotNull(TimeUnit.valueOf(argument));
}
public class ToStringArgumentConverter extends SimpleArgumentConverter {
@Override
protected Object convert(Object source, Class<?> targetType) {
assertEquals(String.class, targetType, "Can only convert to String");
return String.valueOf(source);
}
}
参数聚合(Argument Aggregation)
默认情况下，提供给@ParameterizedTest方法的每个参数都对应于单个方法参数。
因此，期望提供大量参数的参数源可能导致大方法签名。
在这种情况下，可以使用ArgumentsAccessor而不是使用多个参数。
使用这个API，可以通过传递给测试方法的单个参数访问提供的参数
@ParameterizedTest
@CsvSource({
"Jane, Doe, F, 1990-05-20",
"John, Doe, M, 1990-10-22"
})
void testWithArgumentsAccessor(ArgumentsAccessor arguments) {
Person person = new Person(arguments.getString(0),
arguments.getString(1),
arguments.get(2, Gender.class),
arguments.get(3, LocalDate.class));
if (person.getFirstName().equals("Jane")) {
assertEquals(Gender.F, person.getGender());
}
else {
assertEquals(Gender.M, person.getGender());
}
assertEquals("Doe", person.getLastName());
assertEquals(1990, person.getDateOfBirth().getYear());
}

@RequestMapping("/user")
public class UserController {
//读取session
@GetMapping("/get")
public String getsess(HttpServletRequest request) {
HttpSession session=request.getSession();
String username = (String)session.getAttribute("username");
System.out.println("session username:"+username);
if (username == null) {
return "";
} else {
return username;
}
}
//设置session
@GetMapping("/set")
public String setSess(@RequestParam("userName")String userName, HttpServletRequest request) {
HttpSession session=request.getSession();
session.setAttribute("username", userName);
return userName;
}
}@AutoConfigureMockMvc
@SpringBootTest
class UserControllerTest {
@Autowired
private UserController userController;
@Autowired
private MockMvc mockMvc;
private static MockHttpSession session;

public static void setupMockMvc() {
session = new MockHttpSession();
session.setAttribute("username", "刘新漳");

void getTest() throws Exception {
MvcResult mvcResult = mockMvc.perform(get("/user/get")
.session(session)
.contentType(new MediaType("application", "x-www-form-urlencoded")))

String content = mvcResult.getResponse().getContentAsString();
assertThat(content, equalTo("刘新漳"));
