sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) using findElement(By.className()) through Selenium and Java

Question

When I execute the following code:

driver.findElement(By.className(\"qview-product-name\")).click();

I get the following error

Answer 1

There are a couple of things you need to take care of:

• By.className("qview-product-name") refers to the parent <dd> tag and perhaps is not the desired element you want to click. Rather your usecase must be to click on the <a href="Link_here"_blank">Title</a> element.

• As per best practices, while invoking click() you need to induce you need to induce WebDriverWait for the elementToBeClickable() and you can use either of the following Locator Strategies:

• linkText:

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.linkText("Title"))).click();
  

• cssSelector:

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("dd.qview-product-name a[href='Link_here']"))).click();
  

• xpath:

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//dd[@class='qview-product-name']//a[@href='Link_here' and text()='Title']"))).click();
