Cypress - tick() Method Last Updated : 10 Sep, 2024 Comments Improve Suggest changes Like Article Like Report The tick() method in Cypress is a powerful utility that allows you to simulate the passage of time in your tests. It is particularly useful when dealing with functions like setTimeout, setInterval, or any code that requires a delay or timed events. By manually advancing the clock, you can skip wait times, making your tests run faster and more predictably.Usages of Cypress - tick() MethodThe tick() method is often used when testing:Animations or UI components with delays.Functions that rely on timers (e.g., setTimeout and setInterval).Delayed AJAX calls or other asynchronous operations.In Cypress, you typically combine cy.clock() with cy.tick() to control the JavaScript clock in the browser. cy.clock() freezes the time, while tick() advances it by a specified amount.Syntaxcy.tick(milliseconds)Argumentsmilliseconds: (Number) The number of milliseconds by which to advance the clock.Example 1: Using tick() with setTimeoutHTML Code HTML <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>SetTimeout Example</title> </head> <body> <button id="start">Start Timer</button> <div id="message"></div> <script> document.getElementById('start').addEventListener('click', function() { setTimeout(function() { document.getElementById('message').innerText = 'Timer finished!'; }, 5000); }); </script> </body> </html> Cypress Test Code JavaScript describe('setTimeout Example with tick()', () => { it('should display message after 5 seconds using tick()', () => { // Visit the page cy.visit('http://localhost:3000'); // Freeze the clock before the interaction cy.clock(); // Click the 'Start Timer' button cy.get('#start').click(); // Fast-forward time by 5 seconds (5000 milliseconds) cy.tick(5000); // Check if the message is displayed after 5 seconds cy.get('#message').should('have.text', 'Timer finished!'); }); }); ExplanationIn this example, the button starts a timer that updates a message after 5 seconds. The Cypress test uses cy.clock() to freeze time and cy.tick(5000) to fast-forward by 5 seconds. This allows us to test the functionality without actually waiting.Output:OutputExample 2: Using tick() with setIntervalHTML Code HTML <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>SetInterval Example</title> </head> <body> <div id="counter">0</div> <script> let count = 0; setInterval(function() { count++; document.getElementById('counter').innerText = count; }, 1000); </script> </body> </html> Cypress Test Code JavaScript describe('setInterval Example with tick()', () => { it('should update the counter every second using tick()', () => { cy.visit('http://localhost:3000'); // Freeze the clock cy.clock(); // Fast-forward time by 3 seconds (3000 milliseconds) cy.tick(3000); // Check if the counter displays 3 cy.get('#counter').should('have.text', '3'); }); }); ExplanationThis example increments a counter every second using setInterval. The Cypress test uses cy.clock() to freeze time and cy.tick(3000) to advance time by 3 seconds. It checks if the counter value has correctly updated to "3" after fast-forwarding time.Output:OutputConclusionThe tick() method is a valuable tool for simulating the passage of time in tests, enabling you to efficiently test time-based behaviors without waiting for real-time delays. Combining it with cy.clock(), you can gain full control over timers and animations in your application, making your tests run faster and more reliably.
