clearLocalStorage

Clear data in localStorage for current domain and subdomain.

Cypress automatically runs this command before each test to prevent state from being shared across tests. You shouldn’t need to use this command unless you’re using it to clear localStorage inside a single test.

Syntax

cy.clearLocalStorage()
cy.clearLocalStorage(key)
cy.clearLocalStorage(options)
cy.clearLocalStorage(keys, options)

Usage

Correct Usage

cy.clearLocalStorage()  // clear all local storage

Arguments

keys (String, RegExp)

Specify key to be cleared in localStorage.

options (Object)

Pass in an options object to change the default behavior of cy.clearLocalStorage().

Option Default Description
