Cypress - File Operations

Given this Cypress test:

cy.downloadFile('https://example.com/report.pdf', 'cypress/downloads/report.pdf')
cy.readFile('cypress/downloads/report.pdf').should('contain', 'Summary')

The test fails even though the file downloads correctly. What is the likely cause?

Acy.readFile runs before the download completes, causing a race condition

BThe file path in cy.readFile is incorrect

CThe 'contain' assertion is invalid for PDF files

Dcy.downloadFile does not support PDF files

Step-by-Step Solution

Solution:

Step 1: Analyze asynchronous behavior
cy.downloadFile is asynchronous; cy.readFile may execute before download finishes.
Step 2: Understand race condition
Without chaining or waiting, the test reads the file too early.
Step 3: Evaluate other options
File path is correct, 'contain' can be used on text files but PDF content requires parsing, and cy.downloadFile supports PDFs.
Final Answer:
cy.readFile runs before the download completes, causing a race condition -> Option A
Quick Check:
Ensure download completes before reading file [OK]

Quick Trick: Chain commands to wait for download completion [OK]

Common Mistakes:

Not waiting for download to finish before reading file
Assuming 'contain' works directly on binary files like PDFs
