Security-related question about a possible exposed credential

[Emma-NYL]

Hello,

My name is Emma, I am conducting an academic study on possible credential exposure in public GitHub repositories.

While analyzing this repository, I found a string that may represent a credential. I'm including the code snippet below containing possible leakage. To avoid exposing sensitive information publicly, I marked the sensitive information.

Could you please help clarify whether the detected string is:

1. a real credential, or
2. a placeholder / example value?

Thank you for your time.

Code snippet (sensitive values masked):

        it('controller to login a user', async () => {
            const login = new LogInUserDto();
            login.email = 'dwave10****hoo.com';
            login.pin = '1****';
            try {
                const authSpyLoginService = jest.spyOn(authService, 'login');
                const controllerResult = await controller.login(login);
                expect(authSpyLoginService).toBeCalledWith(login);
                expect(controllerResult).toBeCalledWith(login);
            } catch (error) {
                expect(error).toBeInstanceOf(Error);
            }
        });

Thank you in advance for your time - I really appreciate it!

Sincerely,
Emma
