What will be the content of 'data.txt' after running this Cypress code?
cy.writeFile('data.txt', 'Line 1')
cy.writeFile('data.txt', 'Line 2')
ALine 2
BLine 1\nLine 2
CLine 1
DLine 1Line 2
Step-by-Step Solution
Solution:

  1. Step 1: Understand cy.writeFile() default behavior

    Each call overwrites the file content unless append option is used.

  2. Step 2: Analyze the two writeFile calls

    First writes 'Line 1', second overwrites with 'Line 2'. So final content is 'Line 2'.

  3. Final Answer:

    Line 2 -> Option A

  4. Quick Check:

    writeFile overwrites by default = last write wins [OK]
Quick Trick: cy.writeFile overwrites file unless append option used [OK]
Common Mistakes:
  • Assuming writes append by default
  • Expecting both lines concatenated
  • Confusing writeFile with appendFile
