@sridharbandi can you please help on this

sridharbandi commented 1 year ago

@anukodali83 this issue is not because of the java-a11y. Few of the websites with the Chrome strictly enables content security policy: https://stackoverflow.com/questions/53304222/relaxing-chromes-csp-while-running-tests-webdriver-content-security-policy

If you see your developer console, you can see the error: image

Workarounds are you need to disable Chrome CSP.

The second alternative is to modify your framework, as mentioned below

driver.get("https://github.com/sridharbandi/Java-a11y/issues/25");
JavascriptExecutor javascriptExecutor = (JavascriptExecutor) driver;
String htmlcs = Reader.getInstance().getHTMLCS();
javascriptExecutor.executeScript(htmlcs);

Remaining, this should be as default Here is the complete example with above suggested changes. https://github.com/sridharbandi/Java-a11y-example/tree/workaround/issue-26

Hi @anukodali83 It is pretty the same as HtmlCodeSniffer. Below are the same steps for AXE

Remaining, this should be as default Updated https://github.com/sridharbandi/Java-a11y-example/tree/workaround/issue-26 same for AXE.
