Test Code - Cypress

Cypress

describe('User Registration with Dynamic Data', () => {
  it('should register a user with a unique username', () => {
    const uniqueUsername = `user_${Date.now()}`;
    cy.visit('https://example.com/register');
    cy.get('#username').type(uniqueUsername);
    cy.get('#email').type(`${uniqueUsername}@mail.com`);
    cy.get('#password').type('Password123!');

    cy.get('.success-message').should('contain.text', 'Registration successful');
  });
});

Execution Trace - 8 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test runner initialized, no browser opened yet	-	PASS
2	Browser opens and navigates to 'https://example.com/register'	Registration page is loaded with username, email, password fields and register button	Page URL is correct and form elements are visible	PASS
3	Generates a unique username using current timestamp	Variable uniqueUsername holds a string like 'user_1687000000000'	uniqueUsername is a non-empty string with expected format	PASS
4	Finds username input field and types the unique username	Username input contains the unique username text	Input value matches uniqueUsername	PASS
5	Finds email input field and types email based on unique username	Email input contains text like '[e-mail]'	Input value matches generated email	PASS
6	Finds password input field and types 'Password123!'	Password input contains the typed password	Input value matches 'Password123!'	PASS
7	Finds and clicks the register button	Form is submitted, page processes registration	-	PASS
8	Checks for success message containing 'Registration successful'	Success message is visible on the page	Success message text contains 'Registration successful'	PASS
