Prevent cypress type() from firing pointer/mouse events-CodePudding

Testing more complex behavior of user input involving keys with Cypress got me stuck. The app uses hotkeys to trigger operational modes and cannot afford to let random mouse/pointer events get fired whenever a key is pressed. One supposed scenario is

hold down alt key
draw a polygon
release alt key

Using cy.type results in the first two steps registering as a double click, performing an unwanted action. Release key action results in one more point (screen middle) being added to the polygon.

I tried many varians of type() call, tried replacing it with trigger() (did not even fire) with and without focus() combination such as

cy.get(selector)
    .trigger('keydown', { eventConstructor: 'KeyboardEvent', key: key, release: false })
    .trigger('keypress', { eventConstructor: 'KeyboardEvent', key: key, release: false })

tried real cypress events plugin (which seem not to support key press without a release action).

How would you fire just a simple KeyboardEvent event without all the mess around?

CodePudding user response：

If you want to have fine control over the events sent, use plain JS dispatchEvent()

cy.get(selector).then($el => {
  $el[0].dispatchEvent(new KeyboardEvent('keypress', {'key': 'a'}))
})

The fact that trigger() didn't work indicates you haven't identified the correct event or target, it should work the same way as dispatchEvent().

Since you're drawing, maybe you should be looking at mouse events instead of keyboard events (unless the app is supposed to draw using the keyboard).
