Hi all,
I have tried accessibility testing with axe-core using the following steps:
1) inject the axe.min.js file in to web application.
2) execute axe.run with its parameters and fetch results.
But i am facing "type mismatch" error while passing axe.run() along with parameters.Could anyone please help me with this.Thanks!!!
Please find attached the exact code i am trying to use.
Which line of code is producing the error? If it's the var axeScript line, you haven't actually run anything. That's an assignment statement.
i am facing error on the same line (line no 21), has removed the assignment statement still getting type mismatch error. Please find attached the latest code
Here's an example,
function Assessibility()
{
// Launch browser
Browsers.Item(btChrome).Navigate("https://www.google.com/");
var page = Sys.Browser("chrome").Page("*");
page.Wait();
// Inject script
var script = page.contentDocument.createElement("script");
script.src="https://cdnjs.cloudflare.com/ajax/libs/axe-core/4.8.2/axe.min.js";
script.type = "text/javascript";
page.contentDocument.head.appendChild(script);
// Function call
page.contentDocument.Script.eval("axe.run({resultTypes: ['violations']}, function (err, results) {if (err) throw err; console.log(results);});");
}
The function is called, and the output is shown in DevTools,
If I replace console.log(results) with return results, then the object is not returned. I'm not sure how to retrieve the object, and not sure if it's a limitation of Chrome.
Hopefully, this should be enough to get you going, and if you do find out how to retrieve the object, then please provide the solution.
Thanks rraghvani for the example , I was able to achieve the same by injecting below code
in axeScript.textContent as well and see results in console. But even i was not able to return the object so that it can be used later to generate some html results or print the results in testcomplete log.
Hence tried the previously shared approach where i am getting type mismatch error
Will try to retrieve the object, if i get some solution will share the same . Thanks!
Also note, I'm not sure what JavaScript version axe is written in, but it might not be supported by TestComplete.
Certain parameters will need to be converted to JSON,
var json = JSON.stringify({
resultTypes: ['violations']
});
I've never come across axe before, so I don't know how to fully use it.
