How can I execute code before all tests suite with Cypress

cypress login before each test
cypress before each
cypress group tests
cypress beforeeach
cypress run specific test
cypress/support file
cypress before(function)
cypress before beforeeach

Basically, I want to login once before all my tests are executed. My tests files are split on several files.

Should I call my login command in each test file using the before hook or is there any way to to do it once before all tests ?

Writing and Organizing Tests, Current behavior: If user defines global before() or after() hook in the support file CLI ( npx cypress run ) then the global hooks are executed for each .spec file in the suite. Steps to reproduce: (app code and test code) Add multiple spec files; Run all tests with CLI - npx cypress run; Run all tests with  The simplest solution here is to move your reset code to before the test runs. Code put in a before or beforeEach hook will always run prior to the test - even if you refreshed Cypress in the middle of an existing one! This is also a great opportunity to use root level hooks in mocha.

I would login before EACH test because there could be things that happen in a previous test that affects the results of the current test. With a fresh login, you're starting with a clean state every time. If you want to test a "chain" of unrelated actions (action A THEN action B), then write that as a separate test, but have basic functionality in individual tests.

describe('/page'), () => {
  beforeEach(() => {
    cy.login()        // custom command that hanldes login w/o UI
    cy.visit('/page') // go to the page you are testing
  })

  // tests
})

You should include a beforeEach block in every test file. This block should login and navigate to the page in question.

Hook to run before all the tests in Cypress · Issue #91 , what is the recommended way to run some code once before all tests run? and I want /48110258/how-can-i-execute-code-before-all-tests-suite-with-cypress. Short answer: You can write your login command in a before hook within the supportFile (the file that is loaded automatically before your other spec files). This before hook will run before any of the code in your other test files.

describe('Hooks', function() {
    before(function() {
        // runs once before all tests in the block
    })
})

Global before() and after() hooks are executed multiple times when , Global Before Hooks executing before all the tests in cypress - mocha. add to the tests which depend on the data table to be loaded this line of code: Suite as a runner so that I can specify the order of how my test classes will be executed. Using your UI to log in is the exact same scenario as what we described previously. Logging in is a prerequisite of state that comes before all of your other tests. Because Cypress isn’t Selenium, we can actually take a huge shortcut here and skip needing to use our UI by using cy.request(). Because cy.request()

cypress-io/cypress, rimraf : To delete all of existing report files before test runs. So the report is generated after ALL of the tests run via the generateReport function. This guide assumes you’ve already read our Installing Cypress guide and installed Cypress as an npm module. After installing you’ll be able to execute all of the commands in this document from your project root. How to run commands. You can alternatively require and run Cypress as a node module using our Module API.

Global Before Hooks executing before all the tests in cypress, between JUnit annotations that can be used to run logic before tests. when we want to execute some common code before running a test. We are using Cypress for functional live tests. When running live tests we are dealing with real customer data that is somewhat dependent on state, in order for us to run our tests we need to hit real endpoints and perform actual CRUD operations.

Generate a Beautiful Test Report from running Tests on Cypress.io, And then before each one of these tests, before any of the tests run, I'm going to to demonstrate a real scenario with various test suites running in parallel. You can also run code before or after your tests, and add custom commands to  Commit your code again and push it up to GitHub to trigger a new build. Again, four test jobs should run in parallel after the build job finishes. Mochawesome. Moving along, let's add mochawesome as a Cypress custom reporter so we can generate a nice report after all test jobs finish running. Install:

Comments
  • I've read about the supportFile but I'm not sure it can handle asynchronous code like a network request. By handling I mean, make sure all the asynchronous tasks executed in this file are resolved before launching the tests.
  • There is nothing different from the supportFile than any other spec file except that it is loaded before the other spec files. If you are looking to handle some asynchronous requests, you should be using cy.request() for this.
  • So the before hook is equivalent to beforeAll in other frameworks? Good to know, because doing say 'beforeEach(... cy.visit(myUrl)` is really tedious at runtime, when you're just testing that a bunch of static features exist on the page.
  • Yes, the before hook is equivalent to beforeAll.
  • Why would you force a login before each test? I agree in general with the decision of avoiding share state between tests, but I would very much make things like logging in an exception to that rule. Logging in is usually generally takes a second or more. Why would you add that overhead to each test? I think a better alternative to this would be to use preserve once to speed things up.
  • @erandros I can understand your concern. Personally I think it's best to be aware of login and state/session sharing, perhaps logging back in for each set of related tests. Another idea to consider is using cy.request() to POST to login to log a user in instead of using the UI to login in since it's faster (you can also grab or handle cookies during this POST login). Generally though I think Jennifer is correct to warn about sharing state between tests. Ideally the order of tests being run should NOT influence the tests outcome whatsoever.
  • "...there could be things that happen in a previous test that affect the result of the current test..." -- not if you're writing good tests. Tests should not rely on any state changes from separate tests, nor should they make changes that are permanent or carry over to other tests. Mock what you need to!
