Cypress - File Operations

You want to assert that the file summary.txt contains the substring Completed. Which Cypress code snippet correctly performs this check?

Acy.readFile('summary.txt').then((text) => { expect(text).to.include('Completed') })

Bcy.readFile('summary.txt').should('include', 'Completed')

Ccy.readFile('summary.txt').should('contain.text', 'Completed')

Dcy.readFile('summary.txt').should('have.text', 'Completed')

Step-by-Step Solution

Solution:

Step 1: Understand assertion methods
cy.readFile() returns file content as a string, so assertions must be on that string.
Step 2: Analyze options
cy.readFile('summary.txt').then((text) => { expect(text).to.include('Completed') }) uses then() to get the text and asserts with expect(text).to.include(), which is correct.
Step 3: Why others are wrong
Options A, C, and D use should() with incorrect assertions for string content.
Final Answer:
cy.readFile('summary.txt').then((text) => { expect(text).to.include('Completed') }) -> Option A
Quick Check:
Use then() with expect() for substring assertions [OK]

Quick Trick: Use then() and expect() to assert file content substrings [OK]
