junit测试中的assertequals

Question

我有一个方法：

public void addDepartment(String[] list, Department department) {
    if(list[0]!=null && list[0]!=""){
    department.setDepName(list[0]);
    this.departmentDao.addOrEditDepartment(department);
    }
}

我为它做了一个测试用例，它是。。

public void testAddDepartment(){
    Department department = new Department();
    String[] list = new String[1];
    list[0] = "mmm";
    department.setDepId(120);
    department.setDepName(list[0]);
    service.addDepartment(list, department);
    assertEquals("mmm",service.getDepartment(120).getDepName());
    //assertNotNull(service.getDepartment(112).getDepName());
}

但是assertequals中出现一个错误，即assertequal不是函数（string，void）。。但我不知道如何测试它。。有什么帮助吗？

Answer 1

方法assertEquals检查两个对象的标识。

您在这里查看：

• department
• 调用service.addDepartment(list, department)的结果

但是方法addDepartment返回void，因此在该方法中不可用。

也许你想做以下事情：

@Test
public void testAddDepartment(){
    Department department = new Department();
    String[] list = new String[1];
    list[0] = "mmm";
    department.setDepId(120);
    department.setDepName(list[0]);
    service.addDepartment(list, department);
    // Probably you need to change this to what you like to test
    assertArrayEquals(list, service.getListNotShownHere());
}
