ChangeApiConfig

Changes configuration of the ability to CallAnApi that the actor executing this interaction has been configured with.

Changing API URL for all subsequent requests

import { actorCalled } from '@serenity-js/core';
import { By Navigate, PageElement, Text } from '@serenity-js/web';
import { CallAnApi, ChangeApiConfig, GetRequest, LastResponse, Send } from '@serenity-js/rest'
import { Ensure, equals } from '@serenity-js/assertions';

import * as axios from 'axios';

// Let's imagine that the website under test displays
// a dynamically generated API URL that we would like to use
const ApiDetailsWidget = {
  url: () => PageElement.located(By.id('api-url')).describedAs('API URL'),
}

await actorCalled('Apisitt')
  .whoCan(
    BrowseTheWeb.using(protractor.browser),

    // Note: no default base URL is given when the axios instance is created
    CallAnApi.using(axios.create()),
  )
  .attemptsTo(
    Navigate.to('/profile'),

    // We change the API URL based on the text displayed in the widget
    // (although we could change it to some arbitrary string too).
    ChangeApiConfig.setUrlTo(Text.of(ApiDetailsWidget.url())),

    // Any subsequent request will be sent to the newly set URL
    Send.a(GetRequest.to('/projects')),
    Ensure.that(LastResponse.status(), equals(200)),
  )

Changing API port for all subsequent requests

import { actorCalled } from '@serenity-js/core'
import { LocalServer, ManageALocalServer, StartLocalServer } from '@serenity-js/local-server'
import { CallAnApi, ChangeApiConfig, GetRequest, LastResponse, Send } from '@serenity-js/rest'
import { Ensure, equals } from '@serenity-js/assertions'

await actorCalled('Apisitt')
  .whoCan(
    ManageALocalServer.runningAHttpListener(someServer),
    CallAnApi.at('http://localhost'),
  )
  .attemptsTo(
    StartALocalServer.onRandomPort(),
    ChangeApiConfig.setPortTo(LocalServer.port()),
    Send.a(GetRequest.to('/api')),
    Ensure.that(LastResponse.status(), equals(200)),
  )

Setting a header for all subsequent requests

import { actorCalled, Question } from '@serenity-js/core'
import { CallAnApi, ChangeApiConfig, GetRequest, LastResponse, Send } from '@serenity-js/rest'
import { Ensure, equals } from '@serenity-js/assertions'

// A sample Question reading a Node process environment variable
const EnvVar = (var_name: string) =>
    Question.about(`${ name } environment variable`, actor => process.env[var_name]);

await actorCalled('Apisitt')
  .whoCan(
    CallAnApi.at('http://localhost'),
  )
  .attemptsTo(
    ChangeApiConfig.setHeader('Authorization', EnvVar('TOKEN')),
    Send.a(GetRequest.to('/api')),
    Ensure.that(LastResponse.status(), equals(200)),
  )
