a11y automation using axe-selenium and java

Question

followed a simple program from the git hub - https://github.com/dequelabs/axe-selenium-java

public class CheckAxe {

@Rule
public TestName testName = new TestName();

private WebDriver driver;
private static final URL scriptUrl = CheckAxe.class.getResource("/axe.min.js");

@BeforeClass
public void setUp() {
    System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir") + "//Drivers//chromedriver.exe");
    driver = new ChromeDriver();
}

@Test
public void testAccessibility() {
    driver.get("https://www.amazon.com");
    JSONObject responseJSON = new AXE.Builder(driver, scriptUrl).analyze();

    JSONArray violations = responseJSON.getJSONArray("violations");

    if (violations.length() == 0) {
        Assert.assertTrue(true, "No violations found");
    } else {
        AXE.writeResults(testName.getMethodName(), responseJSON);
        Assert.assertTrue(false, AXE.report(violations));
    }
}

@AfterClass
public void tearDown() {
    driver.quit();
}

}

While execution , get error as below -

Seems Like Chrome Driver executable issues.

It is impossible to run Selenium test scripts on the Google Chrome browser without ChromeDriver executable.

Please download the ChromeDriver exe file form ChromeExe

You can keep this file in "C://driver//chromedriver_win32" folder

In your ExampleTest.java class in setup method

public void setUp() {
        // ChromeDriver needed to test for Shadow DOM testing support
         System.setProperty("webdriver.chrome.driver",                 
                   "C://driver//chromedriver_win32//chromedriver.exe");
        driver = new ChromeDriver();
    }
