How can I download and name the downloaded file using loop in cypress?

Question

describe('download',function()
{
it('fils',function()
{
  
cy.visit('url')
cy.get('.ds_class_data_sheet').click()
cy.wait(3000)
const numberoftest=68;
for (let i = 1; i <= numberoftest; i ++) {    
  
cy.get('.dsDocumentData > .dsTitle > .dsDocumentLink').eq(i).then(function(e1)
{
  const url=e1.prop('href')
  
  cy.downloadFile(url,'cypress/downloads/Datasheet','file1.pdf')
  
}

)
}

  

}



)
})

I tried by writing the code like this. There happen the downloads but my question is how do I name the downloaded file using the loop.

Answer 1

To change the name inside the loop, use a string template.

for (let i = 1; i <= numberoftest; i ++) {    
  cy.get('.dsDocumentData > .dsTitle > .dsDocumentLink').eq(i)
    .then(function(e1) {
      const url = e1.prop('href')

      // name whatever format desired, maybe last part of url
      const id = url.split('/')[3]
      const name = `file_${id}`      

      cy.downloadFile(url,'cypress/downloads/Datasheet', name)
    })
}
