Test Overview

This test runs a simple Cypress test inside a Docker container. It opens a webpage, clicks a button, and verifies the expected text appears.

Test Code - Cypress

Cypress

describe('Docker execution test', () => {
  it('opens page, clicks button, and checks text', () => {
    cy.visit('https://example.cypress.io')
    cy.get('a[href="/commands/actions"]').click()
    cy.url().should('include', '/commands/actions')
    cy.get('.action-email').type('test@example.com').should('have.value', 'test@example.com')
  })
})

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Docker container starts with Cypress test environment	Docker container running with Cypress and browser ready	-	PASS
2	Cypress test runner launches and starts the test	Test runner initialized inside Docker	-	PASS
3	cy.visit('https://example.cypress.io') opens the webpage	Browser inside Docker shows example Cypress page	Page loaded successfully	PASS
4	cy.get('a[href="/commands/actions"]').click() clicks the Actions link	Browser navigates to /commands/actions page	Link found and clicked	PASS
5	cy.url().should('include', '/commands/actions') verifies URL	URL contains '/commands/actions'	URL includes '/commands/actions'	PASS
6	cy.get('.action-email').type('test@example.com') types email	Input field with class 'action-email' contains typed email	Input value is 'test@example.com'	PASS

Failure Scenario

Failing Condition: The selector '.action-email' is not found or page fails to load inside Docker
