Cypress: I want run tests in 100 spec files by login one time and persist login for every file. Is it possible?

问题

I have almost 100 specs files including multiple tests. I want run all these specs files by login one time. I dont want my cypress should login process every time on every spec file It it possible to persist single login for all spec files

回答1:

This is the recommend approach that Cypress.io suggest you use, as this is quite the anti-pattern.

Cypress Docs

Anti-Pattern: Sharing page objects, using your UI to log in, and not taking shortcuts.

Best Practice: Test specs in isolation, programmatically log into your application, and take control of your application’s state.

You should have one spec file/few tests that do actually test your login screen/functionality, to confirm that is does indeed work.

But then any other time you should grammatically log into your account via an API and store the credentials in a cookie or token.

That way you should be able to bypass the login screen.

Once you have the API working you can add it into a before hook in the appropriate place.

Take a look at our "Logging in" recipes https://github.com/cypress-io/cypress-example-recipes#logging-in-recipes - most of them log in once using before hook, and then save the cookie / token in a local variable and set it again and again in beforeEach hook

Please see code:

I am storing data in localstorage when login completed

i am calling login method in first file and able to access that localstorate in first file

but in 2nd spec file i am not able to access that token and not logining

// commands.js
Cypress.Commands.add("SignIn", () => {
  cy.visit("https://app-dev.partie.com/");
  const loginBtn = "section.btn-group > a.btn.btn-outline";
  const userNameField = 'input[type="text"]';
  const passwordField = 'input[type="password"]';
  const loginFormBtn = ".bg-blue";

  cy.get(loginBtn).click();
  cy.get(userNameField)
    .type("usrename")
    .get(passwordField)
    .type("!password");
  cy.get(loginFormBtn).click();
  cy.wait(3000);
  cy.setLocalStorage("jwt", "this is token");
  cy.setCookie('foo', 'bar')
 
    
});

/////// first test spec file  and i am abale to access local storate ///////
 before(() => {
    cy.SignIn()
    cy.saveLocalStorage();
   });
  
   beforeEach(() => {
    cy.restoreLocalStorage();
  });
 it("should exist identity in localStorage", () => {
    cy.getLocalStorage("jwt").then(token => {
      cy.log("jwt", token);
    });

    cy.getCookie('foo').should('have.property', 'value', 'bar')
  });
  
  ////////  2nd test spec file and im not able to access token //////////////////
  afterEach(() => {
    cy.saveLocalStorage();
   });
  
   beforeEach(() => {
    cy.restoreLocalStorage();
  });
  it("should exist identity in localStorage", () => {

  cy.getLocalStorage("jwt").then(token => {
    cy.log("jwt", token);
  });
 
});
