cy.clearLocalStorage()

To clear all data in local storage, use the cy.clearLocalStorage() command.

cy.get('.ls-btn').click().should(() => {
  expect(localStorage.getItem('prop1')).to.eq('red')
  expect(localStorage.getItem('prop2')).to.eq('blue')
  expect(localStorage.getItem('prop3')).to.eq('magenta')
})

// clearLocalStorage() yields the localStorage object
cy.clearLocalStorage().should((ls) => {
  expect(ls.getItem('prop1')).to.be.null
  expect(ls.getItem('prop2')).to.be.null
  expect(ls.getItem('prop3')).to.be.null
})

// Clear key matching string in Local Storage
cy.get('.ls-btn').click().should(() => {
  expect(localStorage.getItem('prop1')).to.eq('red')
  expect(localStorage.getItem('prop2')).to.eq('blue')
  expect(localStorage.getItem('prop3')).to.eq('magenta')
})

cy.clearLocalStorage('prop1').should((ls) => {
  expect(ls.getItem('prop1')).to.be.null
  expect(ls.getItem('prop2')).to.eq('blue')
  expect(ls.getItem('prop3')).to.eq('magenta')
})

// Clear keys matching regex in Local Storage
cy.get('.ls-btn').click().should(() => {
  expect(localStorage.getItem('prop1')).to.eq('red')
  expect(localStorage.getItem('prop2')).to.eq('blue')
  expect(localStorage.getItem('prop3')).to.eq('magenta')
})

cy.clearLocalStorage(/prop1|2/).should((ls) => {
  expect(ls.getItem('prop1')).to.be.null
  expect(ls.getItem('prop2')).to.be.null
  expect(ls.getItem('prop3')).to.eq('magenta')
})
