Question

Heads Up: It is my first post here, please excuse any missing information or the really novice questions.

So I am currently trying to write jUnit tests for the already finished web application that uses spring (everything works, I just have to get full coverage with the tests). I have the classes: "Employee", "EmployeeController" and "EmployeeManagement". I want to test the "registerNew" function which creates a new Employee with the filled form "EmployeeRegistrationForm" if it has no errors ("Errors result").

Now I want to write a Test for this to make sure that the function really does create a new object "Employee" which should be saved in the "EmployeeRepository" with said form.

However, I cannot seem to be able to create a filled "EmployeeForm" since it is abstract and cannot be instantiated. Therefore I am struggling to give any argument to that function and do not know how to pass the information needed for the test to function being tested.

@Service

@Transactional

public class EmployeeManagement {

    private final EmployeeRepository employees;
    private final UserAccountManager userAccounts;


    EmployeeManagement(EmployeeRepository employees, UserAccountManager userAccounts) {

        Assert.notNull(employees, "employeeRepository must not be null!");
        Assert.notNull(userAccounts, "UserAccountManager must not be null!");

        this.employees=employees;
        this.userAccounts = userAccounts;
    }

    //the function that creates the employee
    public Employee createEmployee(EmployeeRegistrationForm form) {

        Assert.notNull(form, "Registration form must not be null!");

        String type = form.getType();
        Role role = this.setRole(type);
        UserAccount useraccount = userAccounts.create(form.getUsername(), form.getPassword(), role);

        useraccount.setFirstname(form.getFirstname());
        useraccount.setLastname(form.getLastname());


        return employees.save(new Employee(form.getNumber(), form.getAddress(), useraccount));
    }

@Controller

public class EmployeeController {

    private final EmployeeManagement employeeManagement;

    EmployeeController(EmployeeManagement employeeManagement) {

        Assert.notNull(employeeManagement, "userManagement must not be null!");

        this.employeeManagement = employeeManagement;
    }

    @PostMapping("/registerEmployee")
    @PreAuthorize("hasRole('ROLE_ADMIN')")
    String registerNew(@Valid EmployeeRegistrationForm form, Errors result) {

        if (result.hasErrors()) {
            return "registerEmployee";
        }

        employeeManagement.createEmployee(form);

        return "redirect:/";
    }
public interface EmployeeRegistrationForm {

    @NotEmpty(message = "{RegistrationForm.firstname.NotEmpty}")
    String getFirstname();

    @NotEmpty(message = "{RegistrationForm.lastname.NotEmpty}")
    String getLastname();


    @NotEmpty(message = "{RegistrationForm.password.NotEmpty}")
    String getPassword();

    @NotEmpty(message = "{RegistrationForm.address.NotEmpty}")
    String getAddress();

    @NotEmpty(message = "{RegistrationForm.number.NotEmpty}")
    String getNumber();

    @NotEmpty(message = "{RegistrationForm.type.NotEmpty}")
    String getType();

    @NotEmpty(message = "{RegistrationForm.username.NotEmpty}")
    String getUsername();
}

但是，我似乎无法创建一个已填充的“ EmployeeForm”。因为它是抽象的且无法实例化。

使用Mockito实例化您的抽象类。您可以像这样使用它：

EmployeeForm form = mock(EmployeeForm.class);

现在您有一个EmployeeForm实例，可以将其传递给您的方法。如果您需要从模拟中调用某些方法，则可以执行以下操作：

given(form.getFirstname()).willReturn("John");

通过这种方式，表单将按照您想要的方式运行。

注意：mock()来自org.mockito.Mockito，而given来自org.mockito.BDDMockito。
