How do I do E2E (end-to-end) testing with Cypress for Syncfusion Vue components?

End-to-end testing is a critical aspect of software development, ensuring the comprehensive validation of an application’s functionality and performance throughout its lifecycle. This guide is designed to walk you through the process of performing end-to-end (E2E) testing using Cypress specifically tailored for Syncfusion Vue components.

Prerequisites

System requirements for Syncfusion Vue Components

Create a Vue project

Initialize a Vue project that incorporates the desired Syncfusion component. In this tutorial, we’ll use the Syncfusion TreeGrid component as an example. Refer to the detailed instructions in the Syncfusion Vue TreeGrid getting started documentation.

Add Cypress to the Vue project

To enhance your Vue project with Cypress for E2E testing, follow these steps:

npm install cypress -D

Running Cypress E2E test cases

Execute the following command in the command prompt to launch the Cypress Test Runner interface:

npx cypress open

Upon executing this command, the Cypress Test Runner interface will launch, allowing you to select and execute your desired test cases. Follow these steps in the Cypress Test Runner:

1. Choose the E2E Testing option from the available test suites.

2. Click on the Continue button to proceed with the default Cypress configuration. This ensures a seamless setup for your E2E testing environment.

3. Select your preferred web browser from the options provided to execute the test cases. Ensures compatibility with the chosen browser for accurate test results.

4. To create a new test case, click Create new spec. After updating the test case filename, click on Create spec to finalize the creation of the new test case.

5. Once the spec file is created in the default location, click the Okay, run the spec button to initiate the E2E testing with default test cases.

6. The Syncfusion Vue TreeGrid Component test cases can be composed within the created spec file at cypress\e2e\treegrid.cy.js. Below is an example illustrating a simple test case:

describe('page', () => {
  it('renders', () => {
    // see: https://on.cypress.io/mounting-vue
    cy.visit('http://localhost:8080/')
    cy.get('.e-next').click()
  })
})

7. Upon completing the composition of your test cases, you can validate their execution within the browser. It is vital to ensure that your Vue.js application is actively running while running Cypress tests. Furthermore, you may need to update the URL specified in the cy.visit() command to match the URL of your operating application.

Conclusion

By following this comprehensive procedure, you ensure the seamless integration of Cypress for E2E testing with the Syncfusion Vue TreeGrid component. This approach fosters efficient testing and validation of your Vue.js application, allowing you to assess different aspects of the TreeGrid and validate various behaviors. Extend your Cypress tests as needed to comprehensively evaluate the functionality and performance of Syncfusion Vue components.
