By volunteer real-time insight into the application & # 8217; s demeanour and execution process, the Cypress tryout runner create it easier for QA and developers to identify and adjudicate subject promptly. The moon-curser & # 8217; s interactional interface allow users to interact with the application under test and corroborate the test results.

Key Features of Cypress Test Runner

The Cypress test runner provides a number of lineament that make it an idealistic choice for end-to-end testing. Some of the key features are:

1. Interactive Test Execution: Cypress trial runner provides a graphic interface that countenance you to interact with tests in existent time. This signify that you can see the application being quiz and interact with it while the examination is running.
2. Debugging: Cypress test contrabandist allows you to set breakpoints, suspension and inspect codification during trial execution. This makes it easier to identify and fix issues in the codification.
3. Time Travel:Cypress exam runner provides a time-travel feature that allow you to go rearward and forth between the different states of the coating be tested. This makes it leisurely to debug and understand the behavior of the covering.
4. Rerun Test: You can rebroadcast the Cypress test directly from the Test Runner screen, which reduces the amount of time, move back to IDE and starting the test execution.
5. Real-Time Feedback:Cypress test smuggler render real-time feedback on test results, which allows you to quickly identify issues and fix them.

npx cypress unfastened

Let ’ s automate the below trial scenario and verify the test performance on Cypress Test Runner.

Test Scenario:

Test Case 1:

1. Unfastened URL = & gt;https: //bstackdemo.com/
2. Sign in as user
3. Verify signed-in user is right

Test Case 2:

1. Exposed URL = & gt;https: //bstackdemo.com/
2. Add product to Cart
3. Verify product quantity in the go-cart

Implementation Git Code

Execution

Step 1 Launch the Cypress Test Runner by running the undermentioned command in your undertaking directory:

npx cypress open

Step 2Select the type of testing

Step 3Select the browser on which you want to run your test case

Step 4Select the spec file

Step 5 Cypress Test Runner will be establish just as present in the screenshot below

As the test runs, Cypress provides real-time feedback in the test runner interface, including information about the commands be accomplish, any assertions that fail, and any error that occur.

Cypress Test Runner allows you to:

• View the number of test event being executed along with the position
