java - 从 JUnit 测试用例调用方法失败

Question

我有一个问题:

我的 JUnit 测试用例中有这样的方法:

@Test
public void test1st_scenario() {

    out = Mockito.mock(PrintStream.class);
    System.setOut(out);
    restaurant = new Restaurant();
    employee = new Employee(null, null, null);

    ArrayList<Employee> employees = new ArrayList<Employee>();
    employees.add(new Employee("Luciano", "chef", ExperienceLevel.LOW));
    employees.add(new Employee("Naved", "waiter", ExperienceLevel.LOW));
    employees.add(new Employee("Fabrizio", "waiter", ExperienceLevel.LOW));
    employees.add(new Employee("Amnir", "waiter", ExperienceLevel.LOW));
    employees.add(new Employee("Abel", "barman", ExperienceLevel.LOW));

    restaurant.setBudget(10000);
    employee.increaseExperience(employees, 1, "Luciano");
    Mockito.verify(out).println("The chef experience level increased");
    Assert.assertEquals(8800, restaurant.getBudget());
}

Employee类中的increaseExperience方法是:

public void increaseExperience(ArrayList<Employee> employees,
        int numberOfEmployee, String employeeName) {
    restaurant = new Restaurant();
    String[] parts = employeeName.split(",");
    for (int i = 0; i < numberOfEmployee; i++) 
    {
        for (int a = 0; a < employees.size(); a++) 
        {
            if (employees.get(a).name.equals(parts[i])) 
            {
                if (employees.get(a).job.equals("chef") || employees.get(a).job.equals("barman")) 
                {
                    if (employees.get(a).experience.equals(ExperienceLevel.LOW) || employees.get(a).experience.equals(ExperienceLevel.MEDIUM)) 
                    {
                        if (restaurant.getBudget() >= 1200) 
                        {
                            restaurant.setBudget(restaurant.getBudget() - 1200);
                            if (i == 0)
                                System.out.println("The " + employees.get(a).job + " experience level is increased");
                            else
                                System.out.println(" and the " + employees.get(a).job + " experience level is increased");
                        } 
                        else 
                        {
                            if (i == 0)
                                System.out.println("The " + employees.get(a).job + " experience level is failed to increase");
                            else
                                System.out.println(" and the " + employees.get(a).job + " experience level is failed to increase");
                        }
                    } 
                    else if (employees.get(a).experience.equals(ExperienceLevel.HIGH)) 
                    {
                        if (i == 0)
                            System.out.println("The " + employees.get(a).job + " experience level is increased");
                        else
                            System.out.println(" and the " + employees.get(a).job + " experience level is increased");
                    }
                } 
                else if (employees.get(a).job.equals("waiter")) 
                {
                    if (employees.get(a).experience.equals(ExperienceLevel.LOW) || employees.get(a).experience.equals(ExperienceLevel.MEDIUM)) 
                    {
                        if (restaurant.getBudget() >= 800) 
                        {
                            restaurant.setBudget(restaurant.getBudget() - 800);
                            if (i == 0)
                                System.out.println("The " + employees.get(a).job + " experience level is increased");
                            else
                                System.out.println(" and the " + employees.get(a).job + " experience level is increased");
                        } 
                        else 
                        {
                            if (i == 0)
                                System.out.println("The " + employees.get(a).job + " experience level is failed to increase");
                            else
                                System.out.println(" and the " + employees.get(a).job + " experience level is failed to increase");
                        }
                    } 
                    else if (employees.get(a).experience.equals(ExperienceLevel.HIGH)) 
                    {
                        if (i == 0)
                            System.out.println("The " + employees.get(a).job + " experience level is increased");
                        else
                            System.out.println(" and the " + employees.get(a).job + " experience level is increased");
                    }
                }
            }
        }
    }
}

但是当我在 JUnit 测试方法中将预算设置为 10000 时，我不能将其恢复为 8800。但我仍然得到10000。可能是调用increaseExperience方法失败。

如何解决？

谢谢。

Answer 1

这就是问题，就在你的 increaseExperience 的开头。方法:

restaurant = new Restaurant();

您在该方法中使用的餐厅与测试中的餐厅完全分开。

也许您应该将餐厅作为另一个参数传递？或者员工可能应该知道他们正在工作的餐厅？

(也完全不清楚为什么您在没有任何有用信息的情况下在 increaseExperience 上调用 Employee - 听起来它应该是 Employee 上的实例方法没有您传入员工，或者它应该是 Restaurant 上的实例方法，此时您应该删除 restuarant 变量，或者它应该是 Employee 上的静态方法，因为它作用于许多员工，而不仅仅是一个......从根本上来说，我认为你需要重新审视你的设计。)
