How to mouse hover on canvas element and also how to fetch value from canvas object [SOLVED]


I have a scenario where I need to read values from doughnut chart which is a canvas element and verify the values. I need to fetch below values

Mouse Hover Issue
The tooltip values are inside div element, but it is displayed only when I mouse hover on the canvas element. I tried Move mouse to element and Click but it does not work

Fetching value from Canvas Element Issue
I tried fetching value from canvas element but it returns [Object][Object] instead of actual value

Could you please help me resolve this issue


Hello @nvelagapudi
You can try to use Canvas Addon - Draw On Canvas
It can give the ability to show the value on the canvas element.
In your second step, you need to take a Screenshot of the canvas element to get value from it.

Unfortunately, at the moment, there is no ability to extract text from an image, but I have a workaround.
Use the following website during your test to achieve this.

  1. Take a screenshot from your app.

  2. Navigate to the site Extract Text From an Image | Online Text Extractor | Brandfolder

  3. Upload the image.

  4. get text from the field

You can use my test for example:


You can add a validation to the get text action (if contains text)

Thank you @kfir.yosef for quick response
