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):

Given /^I am logged in$/ do
  visit(path_to("logged_in"))
  
  email = 'email****il.com'
  password = 'supe****cret'
  
  User.create(:email => email, :password => password)
  
  fill_in 'email', :with => email
  fill_in 'password', :with => password
  

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

Sincerely,
Emma
