Conversation
WalkthroughThe changes introduce a Cypress custom command for logging in, update the login form component to support better testability with data attributes and a submit handler, and add a functional end-to-end login test.

🧹 Nitpick comments (3)
src/components/LoginForm.js (1)
18-21: Good addition of form submission handler.The new
handleSubmitfunction correctly prevents the default form submission behavior and calls theonLoginprop with the form data.The comment "or however you're calling it" appears to be leftover from development and could be removed for cleaner code.
const handleSubmit = (e) => { e.preventDefault(); - onLogin(formData); // or however you're calling it + onLogin(formData); };cypress/e2e/login.cy.js (1)
1-5: Good implementation of login test.The test effectively uses the custom
logincommand to verify the login flow. It has a descriptive name that clearly indicates what's being tested.Consider adding more tests to cover edge cases such as:
- Login with invalid credentials
- Login with empty fields
- Login with special characters in the username
cypress/support/commands.js (1)
1-8: Well-structured custom login command.The login command is well implemented with:
- Default parameter values for easy testing
- Clear steps that match user behavior
- Appropriate assertions to verify successful login
One potential improvement would be to make the URL configurable through Cypress environment variables rather than hardcoding
http://localhost:3000:Cypress.Commands.add('login', (name = 'testuser', password = 'anything') => { - cy.visit('http://localhost:3000'); + cy.visit(Cypress.env('baseUrl') || 'http://localhost:3000'); cy.get('[data-testid="input-name"]').type(name); cy.get('[data-testid="input-password"]').type(password); cy.get('[data-testid="login-button"]').click(); cy.get('[data-testid="login-form"]').should('not.exist'); cy.contains(`Welcome, ${name}`).should('exist'); });This would make the command more flexible when testing in different environments.
