Cypress - File Operations
Identify the error in this Cypress test code for file download verification:
cy.downloadFile('https://example.com/data.csv', 'cypress/downloads', 'data.csv')
cy.readFile('cypress/downloads/data.csv').should('contain', 'Name, Age')
AWrong assertion method; should use 'exist' instead of 'contain'
BIncorrect file path in readFile command
CMissing chaining or waiting for download to complete before reading file
Dcy.downloadFile does not exist in Cypress
Step-by-Step Solution
Solution:
  1. Step 1: Check command sequence and chaining

    The download and readFile commands run separately without waiting for download to finish.
  2. Step 2: Identify the need for chaining or waiting

    Without chaining or waiting, readFile may run before download completes, causing test failure.
  3. Final Answer:

    Missing chaining or waiting for download to complete before reading file -> Option C
  4. Quick Check:

    Wait for download before readFile = C [OK]
Quick Trick: Chain commands or wait to ensure download finishes before reading [OK]
Common Mistakes:
  • Running readFile immediately without waiting
  • Assuming cy.downloadFile is not a valid command
  • Using wrong assertion method for content check
