How do I test a click on SVG objects using Selenium webdriver?

Question

I am trying to write a code to check the functionality of a click on an SVG object - for example a US state on this URL

http://www.amcharts.com/svg-maps/?map=usa

This works, but is there a better way to do this? Something without physically moving the mouse?

robert = new Robot();
robert.mouseMove(x, y);
// full click once to get focus on the window
robert.mousePress(MouseEvent.BUTTON1_MASK);
robert.mouseRelease(MouseEvent.BUTTON1_MASK);
// then set the filter
robert.mousePress(MouseEvent.BUTTON1_MASK);
robert.mouseMove(x, y);
robert.mouseRelease(MouseEvent.BUTTON1_MASK);

In SVG, everything displayed is a block defined by coordinates. In your case, every state is a block as well and therefore has an XPath which you will be able to use in your Selenium code.

Use your browser developement tool to analyse the code of the page and find which block corresponds to the state you want to click on.

Here is the element corresponding to California.

<path cs="100,100" d="M371.75,174.28l-1.09,4.03l-1.09,4.03l-1.09,4.03l-1.09,4.03l-1.09,4.03l-1.09,4.03l-1.09,4.03l-1.09,4.02l-1.09,4.03l-1.09,4.02l-1.09,4.02l-1.09,4.02l-1.09,4.02l-1.09,4.02l-1.09,4.02l-1.09,4.02l2.98,4.56l3,4.56l3.02,4.56l3.05,4.55l3.07,4.54l3.09,4.54l3.11,4.53l3.13,4.53l2.41,3.75l2.42,3.75l2.44,3.75l2.45,3.74l2.46,3.74l2.48,3.74l2.49,3.73l2.5,3.73l3.46,5.32l3.48,5.31l3.51,5.3l3.53,5.3l3.56,5.29l3.59,5.28l3.62,5.28l3.9,5.63l-0.39,1.82l0.45,2.66l1.95,5.06l0.13,1.14l0.03,0.03l-0.12,1.14l0.89,1.45l2.36,2.25l0.44,0.95l-0.01,0.07l-0.13,0.6l-0.83,0.59l-3.5,1.82l-2.02,1.65l-2.31,2.87l-0.28,2.66l-0.52,2.14l-0.76,1.62l-0.95,1.44l-1.15,1.26l-1.07,0.67l-0.98,0.09l-0.72,1.83l-0.46,3.58l0.59,2.36l1.64,1.14l0.86,1.39l0.08,1.64l-0.47,1.5l-1.03,1.37l-1.39,0.58l-2.61,-0.31l0,0l-0.11,0.19l-2.16,-0.21l-5.38,-0.65l-5.39,-0.67l-5.38,-0.69l-5.38,-0.7l-5.38,-0.72l-5.38,-0.74l-5.38,-0.76l-5.38,-0.77l-0.01,-0.15l0.44,-2.41l-0.65,-1.04l-1.22,0.26l0.24,-3.21l0.62,-1.39l0.21,-1.45l-0.19,-3.74l-1.69,-4.89l-4.56,-6.68l-2.53,-2.49l-1.78,-2.8l-1.32,-0.98l-1.81,-0.63l-0.79,0.87l-1.93,-1.21l0.94,-2.39l-1.17,-3.95l-1.57,-0.8l-4.25,-0.84l-5.11,-3.34l-1.36,-1.55l-0.04,-2.16l-2.15,-2.43l-2.98,-2.62l-2.02,-0.11l-2.43,-0.93l-3.22,-2.19l-2.03,-0.72l-4.14,-0.74l-1.44,-0.67l-0.97,-1.94l-1.29,-1.19l0.85,-1.82l0.29,-1.78l0.6,-1.28l0.15,-3.13l1.28,-2.58l-0.18,-1.11l-0.63,-0.99l-2.33,-1.86l-0.09,-1.53l0.98,-1.82l-0.33,-1.47l-1.82,-1.8l-1.25,-3.28l-2.13,-2.21l-0.34,-2.78l-1.13,-1.98l-0.15,-1.51l-2.06,-5.84l-2.58,-4.85l0.07,-2.34l0.73,-3.02l1.97,-1.4l1.24,-1.37l0.35,-1.49l0.09,-1.14l-0.71,-2.24l-4.53,-2.54L303,265.5l0.82,-3.6l-0.46,-4.07l0.68,-2.35l0.53,-2.61l1.33,-0.21l0.98,0.51l-0.41,0.98l-0.19,1.92l0.81,1.73l0.99,0.94l0.67,1.64l0.68,0.64l0.8,0.34l-0.19,-0.98l-0.31,-0.68l-0.05,-1.93l-0.42,-2.57l-0.88,-1.61l0.04,-2.45l-0.38,-0.69l-0.09,-0.94l1.5,-0.64l1.85,-0.22l2.25,0.46l6.14,2.16l1.5,-0.19l1.04,0.51l0.83,0.16l-1.52,-1.09l-1.01,-0.08l-1.08,-0.45l-2.26,-0.53l-0.83,-0.52l-0.78,-1l-0.63,-0.26l-2.42,0.63l-0.87,-0.42l-1.77,-1.99l-0.89,-0.47l-1.75,0.31l-1.18,3.25l-0.27,2.6l-0.99,-0.02l-0.76,-1.33l-1.45,-1.09l-1.06,-1.33l-1.37,-2.29l-0.8,-0.93l-1.56,1.08l0.16,-0.66l1.06,-1.48l0.69,-2.82l1.02,2.73l-0.05,-1.72l-0.79,-2.11l-0.82,-0.9l-0.31,-3.45l-2.24,-2.71l-1.33,-3.67l-3.05,-6.35l1.05,-4.41l0.06,-5.98l1.68,-2.88l0.6,-2.23l0.24,-3.58l-0.27,-2.07l-2.08,-6.11l-2.43,-4.46l0.29,-2.69l0.58,-2.62l1.49,-2.02l1.42,-2.17l0.68,-0.48l0.1,0.32l-0.3,0.47l0.44,0.31l0.52,-0.99l0.47,-0.45l-0.5,-0.24l0.16,-0.32l0.52,-0.56l2.08,-2.78l1.15,-3.98l2.69,-4.47l0.46,-1.61l0.37,-3.67l-0.06,-2.29l-0.82,-1.88l1.25,-1.95l0.61,-2.05l-0.15,-0.43l4.31,1.38l4.17,1.32l4.18,1.31l4.18,1.3l4.19,1.28l4.19,1.27l4.19,1.26l4.2,1.25l4.2,1.23l4.2,1.22l4.21,1.21l4.21,1.2l4.21,1.19l4.22,1.17l4.22,1.16L371.75,174.28zM327.88,344.91l3.35,2.08l2.11,0l0.21,0.63l-0.36,0.4l-4.66,-0.35l-1.21,-0.95l0.09,-0.83l-0.25,-0.89L327.88,344.91zM319.97,344.03l-0.97,-0.2l-1.4,-0.63l0.65,-0.36l0.91,-0.14l0.18,0.34L319.97,344.03zM324.06,347.59l-1.34,-0.04l-0.88,-0.55l-0.96,-2.47l3.3,0.61l1.15,1.27l0.12,0.3L324.06,347.59zM351.66,367.08l0.52,1.82l-1.27,-0.53l-1.4,-0.26l-0.2,-0.97l-0.11,-1.31l-0.2,-0.38l-0.92,-0.35l-0.04,-0.13l0.04,-0.61l0.34,-0.21l2.62,2.09L351.66,367.08zM330.94,365.63l-0.82,-0.17l-1.06,-0.49l-0.26,-1.31l0.93,0.16l0.8,0.38l0.43,1.09L330.94,365.63zM348.58,379.15l-1.11,-0.07l-1.07,-0.74l-0.49,-2.35l-0.7,-1.92l0.72,-0.31l0.51,1.8l1.67,2.96L348.58,379.15z" fill="#FFFFFF" fill-opacity="0.8" stroke="#000000" stroke-opacity="0.5" stroke-width="0.5"></path>

When you have found it, right click on the element and "Copy XPath".

//*[@id="chartdiv"]/div/div[1]/svg/g[7]/g/g[1]/path[47]

However, do it two more times and you will see that the last node is never the same.

//*[@id="chartdiv"]/div/div[1]/svg/g[7]/g/g[1]/path[5]
//*[@id="chartdiv"]/div/div[1]/svg/g[7]/g/g[1]/path[34]

So we would like to find the <path> in //*[@id="chartdiv"]/div/div[1]/svg/g[7]/g/g[1]/ which the d attribute value starts with M371.75,174.28l. It should be something like:

//*[@id="chartdiv"]/div/div[1]/svg/g[7]/g/g[1]/path[starts-with(@d, "M371.75,174.28l")]

You shall have to repeat all these steps by yourself, because we might not have the same generated SVG.

But because the SVG is using another namespace:

/g becomes /*[name()="g"]
/svg becomes /*[name()="svg"]
/path becomes /*[name()="path"]

Which gives the following XPath:

//*[@id="chartdiv"]/div/div[1]/*[name()="svg"]/*[name()="g"][7]/*[name()="g"]/*[name()="g"][1]/*[name()="path"][starts-with(@d, "M371.75,174.28l")]

In Selenium:

webDriver.findElement(
  By.xpath(
    '//*[@id="chartdiv"]/div/div[1]/*[name()="svg"]/*[name()="g"][7]/*[name()="g"]/*[name()="g"][1]/*[name()="path"][starts-with(@d, "M371.75,174.28l")]'
  )
).click();

title() is dedicated to tag values (i.e. <a>VALUE</a>) whereas @title is for attribute values (i.e. <a title="VALUE"></a>). In your case "Montana" isn't the value of the <a> tag, but the value of the title tag attribute, so it will be [starts-with(@title, 'Montana')].

That gives a NoSuchElementException. (Thank you for the help btw). WebElement montana = driver.findElement(By.xpath("//*[@id='ext-gen203']/svg/a[starts-with(@title(), 'Montana')]"));

Then I get a NoSuchElementException. WebElement montana = driver.findElement(By.xpath("//*[@id='ext-gen203']/svg/a[starts-with(@title, 'Montana')]"));

Stéphane Bruckert Over a year ago

Found it: the g, svg and path elements are not detected by Selenium, you have to call them differently: /*[name()='tagname']. Please read my udpated post. I tried it and it works. In your case, the following will probably work:

WebElement montana = driver.findElement(By.xpath("//*[@id='ext-gen203']/*[name()='svg']/a[starts-with(@title, 'Montana')]"));

. (The site is down right now, I couldn't check)

Stéphane Bruckert Over a year ago

I got some answers and advices on my other question. And here we go with a simpliest XPath query: //*[name()='a'][@*[name()='title'][.='Alaska']]. Tested and approved.
