The process of automating e-signature input with Selenium

Is there a way to automate e-signature input in Selenium?

I attempted using the action class to draw a line on the canvas object. Below is the code I used:

    Actions actionBuilder=new Actions(driver);          
Action drawOnCanvas=actionBuilder
            .contextClick(canvas_div)
            .moveToElement(wbCanvas,8,8)
            .clickAndHold(wbCanvas)
            .moveByOffset(120, 120)
            .moveByOffset(60,70)
            .moveByOffset(-140,-140)
            .release(canvas_div)
            .build();
    drawOnCanvas.perform();

Although Selenium can identify the canvas element and mouse movement is visible, nothing is drawn on the canvas element.

Currently, manual input from an e-signature device is required. Below is the HTML code for the element:

<div class="col-lg-12 col-md-12 col-sm-12" id="canvas_div">
                            <canvas height="75" class="col-lg-12 col-md-12 col-sm-12" id="eSignatureDialog_canvas" style="border: 1px solid rgb(0, 0, 0); border-image: none;" name="eSignatureDialog_canvas">
                            </canvas>
                        </div>

Answer №1

It looks like your code is mostly correct, but there's one part that could be improved:

.contextClick(canvas_div)

Instead of that line, you might want to try:

.click(wbCanvas)

If you're interested, you can find a similar example that works here.
