respondOnce

Only respond once with given overwrite. You can call respondOnce multiple consecutive times and it will start with the respond you defined last. If you only use respondOnce and the resource is called more times a mock has been defined than it defaults back to the original resource.

Usage

mock.respondOnce(overwrites, { header, statusCode, fetchResponse })

Parameters

Name	Type	Details
overwrites	MockOverwrite	payload to overwrite the response
params optional	MockResponseParams	additional respond parameters to overwrite
params.header optional	Object	overwrite specific headers
params.statusCode optional	Number	overwrite response status code
params.fetchResponse optional	Boolean	fetch the real response before responding. false skips the backend and throws when the mock filters on statusCode or responseHeaders

Example

respondOnce.js

async function getToDos () {
    await $('#todo-list li').waitForExist()
    return $$('#todo-list li').map(el => el.getText())
}

it('should demonstrate the respondOnce command', async () => {
    const mock = await browser.mock('https://todo-backend-express-knex.herokuapp.com/', {
        method: 'get'
    })

    mock.respondOnce([{
        title: '3'
    }, {
        title: '2'
    }, {
        title: '1'
    }])

    mock.respondOnce([{
        title: '2'
    }, {
        title: '1'
    }])

    mock.respondOnce([{
        title: '1'
    }])

    await browser.url('https://todobackend.com/client/index.html?https://todo-backend-express-knex.herokuapp.com/')
    console.log(await getToDos()) // outputs [ '3', '2', '1' ]
    await browser.url('https://todobackend.com/client/index.html?https://todo-backend-express-knex.herokuapp.com/')

    await browser.url('https://todobackend.com/client/index.html?https://todo-backend-express-knex.herokuapp.com/')
    console.log(await getToDos()) // outputs [ '1' ]
    await browser.url('https://todobackend.com/client/index.html?https://todo-backend-express-knex.herokuapp.com/')
    console.log(await getToDos()) // outputs actual resource response
})
