如何在赛普拉斯中声明localStorage

我担心自己做错了，但是文档中没有明确的示例。

我有一个通过登录流程的测试。我还想验证一下登录后在localStorage内是否已设置某些值。

当我执行以下操作时，我收到一个AssertionError，“预期存在null”：

describe("Trying to log in...", function() {
  it("Visits the Home Page", function() {
    cy.visit("/") // Uses baseUrl prefix from config

    // [ ... snip ... ]

    // Form should be visible and fillable now!
    cy.get("form")
      .should("be.visible")
      .within(() => {
        cy.findByLabelText(/email address/i)
          .should("exist")
          .should("be.visible")
          .click() // Clicking the label should focus the element:
          .type("[test username]")
        cy.findByLabelText(/password/i)
          .click()
          .type("[test password]")
        cy.findByText(/sign in/i).click()
      })

    // Now we're logged in... 

    cy.url().should("include", "home")

    // ========= THE FOLLOWING BREAKS: =======================
    // Check for our localStorage item:
    expect(localStorage.getItem("KeyToOurValue")).to.exist()
  })
})

但是，如果我将其expect放在最后一个回调中should，则似乎可行？

describe("Trying to log in...", function() {
  it("Visits the Home Page", function() {
    cy.visit("/") // Uses baseUrl prefix from config

    // [ ... snip ... ]

    // Form should be visible and fillable now!
    cy.get("form")
      .should("be.visible")
      .within(() => {
        cy.findByLabelText(/email address/i)
          .should("exist")
          .should("be.visible")
          .click() // Clicking the label should focus the element:
          .type("[test username]")
        cy.findByLabelText(/password/i)
          .click()
          .type("[test password]")
        cy.findByText(/sign in/i).click()
      })

    // Now we're logged in... 

    cy.url().should("include", "home", ()=> {
        // ========= THE FOLLOWING WORKS! ========
        // Check for our localStorage item:
        expect(localStorage.getItem("KeyToOurValue")).to.exist()
    })
  })
})

那是我应该怎么做？

看来我应该可以做第一个方法？

在某一cy行运行之后，对localStorage值进行资产化的正确方法是什么？
