Simulating a continuous key press on the keyboard for 5 seconds with TestCafe

Despite my attempts to send it to the browser console by using .pressKey("PageDown") after tracking it, nothing seems to be happening. I'm at a loss on what steps to take next - perhaps there are some examples available? I was advised to utilize the clientfunction, but I'm struggling to put everything together without any concrete examples to guide me. Below is the code I've tried:

    await t
       .click(S(sCounter))
       .pressKey("PageDown");
    await t.eval(() => {
    document.addEventListener("keydown", function (event) {
        console.log(event.key);

        if (event.key === "PageDown") {
            console.log("PageDown press");
            let isKeyPressed = false;
            let timeoutId: ReturnType<typeof setTimeout> | null = null;
            isKeyPressed = true;
            timeoutId = setTimeout(() => {
                isKeyPressed = false;
                if (timeoutId !== null) {
                    clearTimeout(timeoutId);
                }
            }, 10 * 1000); // set the timeout to the specified number of seconds
        }
        console.log("PageDown Up");
    });
});

Answer №1

To mimic the pressing of a key, the t.pressKey action triggers a series of "keydown", "keypress", and "keyup" events. If you want to simulate holding down a key, you can utilize the t.dispatchEvent action. Check out this example for reference: https://github.com/DevExpress/testcafe/issues/1839#issuecomment-1506640783.

Furthermore, based on your code snippet, it is essential to include an event listener before executing the action. Ensure that the t.eval call precedes both the click and pressKey actions.
