How to get, store and reuse firebase token in cypress api automated testing-CodePudding

after sending in body "email" and "password" https://identitytoolkit.googleapis.com/ returns a few objects in the response. One of them is "idToken": with a value of the token.

What do I need?

I need to get this token, store it in variable and reuse it in further tests.

So far I prepared something like this:

        it("Get a fresh admin firebase token", () => {
            cy.request({
                method: "POST",
                url: "https://identitytoolkit.googleapis.com/...",
                body: {
                    "email": "myUsername",
                    "password": "myPassword",
                    "returnSecureToken": true
                },
                headers: {
                    accept: "application/json"
                }
            }).then((responseToLog) => {
                cy.log(JSON.stringify(responseToLog.body))
            }).then(($response) => {
                expect($response.status).to.eq(200);
        })
    })
})```

Above code works, but cy.log() returns the whole body response. How can I separate only idToken and reuse it in my next API scenarios?

CodePudding user response：

Considering that idToken in in response body so inside then() you can directly wrap the value and save it using an alias and then use it later.

it('Get a fresh admin firebase token', () => {
  cy.request({
    method: 'POST',
    url: 'https://identitytoolkit.googleapis.com/...',
    body: {
      email: 'myUsername',
      password: 'myPassword',
      returnSecureToken: true,
    },
    headers: {
      accept: 'application/json',
    },
  }).then((response) => {
    cy.wrap(response.body.idToken).as('token')
  })
})

cy.get('@token').then((token) => {
  cy.log(token) //logs token or Do anything with token here
})

In case you want to use the token in a different it block you can:

describe('Test Suite', () => {
  var token
  it('Get a fresh admin firebase token', () => {
    cy.request({
      method: 'POST',
      url: 'https://identitytoolkit.googleapis.com/...',
      body: {
        email: 'myUsername',
        password: 'myPassword',
        returnSecureToken: true,
      },
      headers: {
        accept: 'application/json',
      },
    }).then((response) => {
      token = response.body.idToken
    })
  })

  it('Use the token here', () => {
    cy.log(token) //prints token
    //use token here
  })
})
