Cypress is an end-to-end testing framework for front-end web applications. It allows you to write tests for your application and simulate user interactions in a browser environment. Sometimes, during testing, you may want to abort a test due to certain unexpected conditions or errors. Cypress provides an easy way to abort a test using the cy.on()
command.
cy.on('test:after:run', (test, runnable) => {
if (test.state === 'failed' || runnable.tests.some(t => t.state === 'failed')) {
Cypress.runner.stop()
}
})
The above command listens for a test:after:run
event, which is triggered after each test is executed. It then checks if the test or any of its sub-tests have failed. If so, it calls Cypress.runner.stop()
to abort the Cypress test.
Suppose you have a Cypress test that clicks on a button and expects a certain element to be visible. If the element is not visible, you want to abort the test. You can use the following code snippet to achieve this:
it('should click on button and verify element is visible', () => {
cy.get('#button').click()
cy.get('#element').should('be.visible')
})
cy.on('test:after:run', (test, runnable) => {
if (test.state === 'failed' || runnable.tests.some(t => t.state === 'failed')) {
Cypress.runner.stop()
}
})
If the cy.get('#element').should('be.visible')
assertion fails, the test will be aborted.
In this article, we have seen how to abort a Cypress test using the cy.on()
command. This feature can be useful for handling unexpected errors during testing.
