mock final类相对简单,直接贴代码 被测方法: public class FinalEmployeeService { public void insertEmployee(Employee employee) { FinalEmployeeDao employeeDao = new FinalEmployeeDao(); employeeDao.insertEmployee(employee); } } final 类 final public class FinalEmployeeD
也相对简单,直接贴代码 被测方法 public class EmployeeServiceWithParam { public void createEmployee(final Employee employee) { EmployeeDaoWithParam employeeDao = new EmployeeDaoWithParam(false, Dialect.MYSQL); employeeDao.insertEmploye(employee); } } public class Em
情型1:static final属性,无法修改其值. package m5.d7; import java.lang.reflect.Field; public class FieldTest { public static void main(String[] args) { try { A a = new A(); Field field = a.getClass().getDeclaredField("a"); field.setAccessible(true); field.s
Mockito是很常用的测试工具,使用过程中可能会遇到下面的问题: Mockito cannot mock/spy because : - final class 问题重现: 引入该依赖到项目的maven配置如下: <dependency> <groupId>org.mockito</groupId> <artifactId>mockito-core</artifactId> <version>3.3.3</version>
有些对象需要mock的对象是由工厂方法产生出来的,而工厂方法一般是静态方法,这时候就需要同时mock工厂方法及对象 被测方法: public class EmployeeServiceFactory { public void saveEmployee(Employee employee){ EmployeeDaoFactory dao = EmployeeDaoFactory.newInstance(); method("powermock"); dao.addEmployee(em
在编写代码时,经常需要调用别人已经写好的工具类,而这些工具提供的方法经常是static方法,在这里,直接贴出<PowerMock实战手册>中的例子 待测试方法: public class EmployeeService { public int getEmployeeCountWithStatic() { return EmployeeUtils.getEmployeeCount(); } } 引用的工具类 public class EmployeeUtils { public static
在开发时,经常遇到这种情况,被测试方法所调用的类不是通过构造注入的,而是通过临时new出来的,如下面待测方法: public class EmployeeService { private EmployeeDao employeeDao; public int getTotalEmployeeWithTempVariable() { EmployeeDao employeeDao = new EmployeeDao(); return employeeDao.getTotal(); } } em
import java.util.Random; public class CodeWithPrivateMethod { public void meaningfulPublicApi() { if (doTheGamble("Whatever", 1 << 3)) { throw new RuntimeException("boom"); } } private boolean doTheGamble(String whatever, int bin
大家都清楚java中String类是不可变的,它的定义中包含final关键字.一旦被创建,值就不能被改变(引用是可以改变的). 但这种“不可变性”不是完全可靠的,可以通过反射机制破坏.参考一下代码: String str = "abc"; System.out.println(str); Field field = String.class.getDeclaredField("value"); field.setAccessible(true); char[] va
PowerMockito.mockStatic时忽略加载类的静态field,比如想PowerMockito.mockStatic(ClassA.class),ClassA如下 public class ClassA { private static final boolean CONF_FLAG = Configuration.getConfig() .get(Status.Initialization).getConfFlag(); // throws an NPE public static
