What is Cypress?

Cypress is a purely JavaScript-based front-end testing tool built for the modern web. It aims to address the pain points developers or QA engineers face while testing an application. Cypress is a more developer-friendly tool that uses a unique DOM manipulation technique and operates directly in the browser.


INSTALL CYPRESS

Introduction: 

Cypress is an end-to-end testing framework that enables developers to test their web applications efficiently. It has gained popularity over the years due to its powerful testing capabilities and ease of use. Recently, Cypress released version 12 with several changes that will enhance the testing experience for developers. In this blog, we will take a closer look at the changes in Cypress version 12.

  1. Automatic retries:

    One of the most significant changes in Cypress version 12 is the introduction of automatic retries. When a test fails, Cypress will automatically retry it up to three times before marking it as a failure. This feature will save developers time by eliminating the need to rerun tests manually. Additionally, developers can customize the number of retries and the wait time between retries.

  2. Improved performance:

    Cypress version 12 also comes with improved performance. The framework now has a faster startup time, and the test runner is more responsive. These changes will significantly reduce the time it takes to run tests and provide a smoother testing experience for developers.

  3. Network stubbing improvements:

    Cypress version 12 has also improved network stubbing capabilities. Developers can now intercept and modify responses from the server using the cy.intercept() command. This feature will enable developers to test edge cases and error handling scenarios more effectively.

  4. New plugin system:

    Another significant change in Cypress version 12 is the introduction of a new plugin system. The new system is more flexible and provides developers with more control over how they use Cypress. Developers can now create their custom plugins and share them with the community. Additionally, developers can install plugins from the Cypress plugin registry, making it easier to add new features to their tests.

Conclusion:

Cypress version 12 comes with several changes that will make the testing experience more efficient and effective for developers. With automatic retries, improved performance, network stubbing improvements, and a new plugin system, developers will have more control over how they use Cypress. These changes will enable developers to create more robust tests and ensure that their web applications are functioning correctly.

How to rerun Failed test cases using TestNG and Selenium

Introduction

With test retries, Cypress is able to retry failed tests to help reduce test flakiness and continuous integration (CI) build failures. By doing so, this will save your team valuable time and resources so you can focus on what matters most to you.

Lets explore on How to rerun the failed test cases in Cypress?

How to rerun the failed test cases in Cypress?

By default, tests will not retry when they fail. You will need to enable test retries in your configuration to use this feature.

Configure Test Retries

Global Configuration

Typically you will want to define different retry attempts for cypress run versus cypress open. You can configure this in the Cypress configuration by passing the retries option an object with the following options:

  • runMode allows you to define the number of test retries when running cypress run
  • openMode allows you to define the number of test retries when running cypress open
{
  "retries": {
    // Configure retry attempts for `cypress run`
    // Default is 0
    "runMode": 2,
    // Configure retry attempts for `cypress open`
    // Default is 0
    "openMode": 0
  }
}

Configure retry attempts for all modes

If you want to configure the retry attempts for all tests run in both cypress run and cypress open, you can configure this in the Cypress configuration by defining the retries property and setting the desired number of retries.

{
  "retries": 1
}

Custom Configurations

Individual Test(s)

If you want to configure retry attempts on a specific test, you can set this by using the test's configuration.

// Customize retry attempts for an individual test
describe('User sign-up and login', () => {
  // `it` test block with no custom configuration
  it('should redirect unauthenticated user to sign-in page', () => {
    // ...
  })

  // `it` test block with custom configuration
  it(
    'allows user to login',
    {
      retries: {
        runMode: 2,
        openMode: 1,
      },
    },
    () => {
      // ...
    }
  )
})

Test Suite(s)

If you want to configure try attempts for a suite of tests, you can do this by setting the suite's configuration.

// Customizing retry attempts for a suite of tests
describe('User bank accounts', {
  retries: {
    runMode: 2,
    openMode: 1,
  }
}, () => {
  // The per-suite configuration is applied to each test
  // If a test fails, it will be retried
  it('allows a user to view their transactions', () => {
    // ...
  }

  it('allows a user to edit their transactions', () => {
    // ...
  }
})

You can find more information about custom configurations here: Test Configuration



Once test retries are enabled, tests can be configured to have X number of retry attempts. For example, if test retries has been configured with 2 retry attempts, Cypress will retry tests up to 2 additional times (for a total of 3 attempts) before potentially being marked as a failed test.

When each test is run again, the following hooks will be re-run also:

  • beforeEach
  • afterEach

Below is a detailed step-by-step example of how test retries work:

Assuming we have configured test retries with 2 retry attempts (for a total of 3 attempts), here is how the tests might run:

  1. A test runs for the first time. If the test passes, Cypress will move forward with any remaining tests as usual.

  2. If the test fails, Cypress will tell you that the first attempt failed and will attempt to run the test a second time.


  1. If the test passes after the second attempt, Cypress will continue with any remaining tests.

  2. If the test fails a second time, Cypress will make the final third attempt to re-run the test.



  1. If the test fails a third time, Cypress will mark the test as failed and then move on to run any remaining tests.


The following is a screen capture of what test retries looks like on the same failed test when run via cypress run.


During cypress open you will be able to see the number of attempts made in the Command Log and expand each attempt for review and debugging if desired.

Screenshots

When a test retries, Cypress will continue to take screenshots for each failed attempt or cy.screenshot() and suffix each new screenshot with (attempt n), corresponding to the current retry attempt number.

With the following test code, you would see the below screenshot filenames when all 3 attempts fail:

describe('User Login', () => {
  it('displays login errors', () => {
    cy.visit('/')
    cy.screenshot('user-login-errors')
    // ...
  })
})

// screenshot filename from cy.screenshot() on 1st attempt
'user-login-errors.png'
// screenshot filename on 1st failed attempt
'user-login-errors (failed).png'
// screenshot filename from cy.screenshot() on 2nd attempt
'user-login-errors (attempt 2).png'
// screenshot filename on 2nd failed attempt
'user-login-errors (failed) (attempt 2).png'
// screenshot filename from cy.screenshot() on 3rd attempt
'user-login-errors (attempt 3).png'
// screenshot filename on 3rd failed attempt
'user-login-errors (failed) (attempt 3).png'
