Cypress - attribute containing text and end of string

I can't see why the original code doesn't work, it looks perfectly good (without a running system to play with).

But the "fix" variation is backwards - the last intercept that is set up is the first to match.

From the docs: enter image description here

This diagram shows route5 being the first (non-middleware) route checked, followed by route3, then route1.


Also, since each intercept is intended to catch only one call, add { times: 1 }, to make it so.

Given('I log in', () => {
  cy.intercept('GET', `**/user/peers`, {times: 1})
    .as('Peers1')                                     // catches 2nd call
  cy.intercept('GET', `**/user/peers`, {times: 1})
    .as('Peers0')                                     // catches 1st call
})

You can see it in this screenshot

enter image description here

where Peers1 is matched first then Peers0, but the following block is expecting the reverse order

Then('the dashboard displays {int} peers', expectedPeersCount => {
  cy.wait(`@Peers${expectedPeersCount }`).then(xhr => {
      const peers = xhr.response.body
      expect(peers.length).to.eq(expectedPeersCount)
  });
})

Called with 0 by And the dashboard displays 0 peers and then called with 1 by Then the dashboard displays 1 peers


Dynamic aliases

You might be able to set the alias dynamically depending on how many peers are in the response.

Given('I log in', () => {
  cy.intercept('GET', `**/user/peers`, (req) => {
    req.continue().then(res => {
      if (re.body.length === 0) {
        req.alias = 'Peers0'
      }
      if (re.body.length === 1) {
        req.alias = 'Peers1'
      }
    })
  })
})

If this works, then you don't need to worry about the order of setup.

Complete JUnit 5 Mockito Tutorial For Unit Testing

Mockito is a unit testing framework for Java that simplifies the task of automation testing. It makes unit testing highly effective with clean tests, thanks to dependency injection and compile-time checks. In addition, Mockito helps improve the test independence of components being developed by helping you create objects that have no dependencies on a test-specific configuration. The most popular way of using Mockito is within the JUnit framework to help you write better tests.

Complete Guide To Cypress Visual Regression Testing

Sometimes referred to as automated UI testing or visual regression testing, VRT checks software from a purely visual standpoint (taking a screenshot and comparing it against another approved screenshot). Cypress is an emerging test automation framework that enables teams to ship high-quality products faster.

How To Minimize Browsers In Selenium WebDriver Using JUnit

Delivering software with superior UI is one of the key aspects of development, but there are times when you need to test the most complicated functionality. These tests include window resizing or minimizing or maximizing, all of which require interacting with the browser window, and if the number of tests is high, it becomes cumbersome. Minimizing browser windows in Selenium with JUnit can be used for automating interactions with browser windows. There are scenarios where minimization of browser windows is a must-have operation to proceed with other scenarios in the respective test suite.

Cypress Tutorial

Cypress is a renowned Javascript-based open-source, easy-to-use end-to-end testing framework primarily used for testing web applications. Cypress is a relatively new player in the automation testing space and has been gaining much traction lately, as evidenced by the number of Forks (2.7K) and Stars (42.1K) for the project. LambdaTest’s Cypress Tutorial covers step-by-step guides that will help you learn from the basics till you run automation tests on LambdaTest.

Chapters:

  1. What is Cypress? -
  2. Why Cypress? - Learn why Cypress might be a good choice for testing your web applications.
  3. Features of Cypress Testing - Learn about features that make Cypress a powerful and flexible tool for testing web applications.
  4. Cypress Drawbacks - Although Cypress has many strengths, it has a few limitations that you should be aware of.
  5. Cypress Architecture - Learn more about Cypress architecture and how it is designed to be run directly in the browser, i.e., it does not have any additional servers.
  6. Browsers Supported by Cypress - Cypress is built on top of the Electron browser, supporting all modern web browsers. Learn browsers that support Cypress.
  7. Selenium vs Cypress: A Detailed Comparison - Compare and explore some key differences in terms of their design and features.
  8. Cypress Learning: Best Practices - Take a deep dive into some of the best practices you should use to avoid anti-patterns in your automation tests.
  9. How To Run Cypress Tests on LambdaTest? - Set up a LambdaTest account, and now you are all set to learn how to run Cypress tests.
