Testing a negative flow in Selenium webdriver

Question

Issue:- webelement (Button) isdisplayed() doesn't works for negative scenarios

Requirement:- I need to fail a test flow in case a button is not displayed on the screen and if its present, then proceed with the flow

Code:-

if (driver.findElement(By.id("button")).isDisplayed() == false) {
System.out.println("The Button isn't present. Exiting!!");
driver.findElement(By.linkText("Logout")).click();
}
else
{
//Proceed with the positive flow
}

In above code, if the button is not present at all on the screen, the test should fail (if statement should be executed, but it's not)

Answer 1

As TestAutomationEngr has mentioned, make sure there is only one type of such button on the page...

one more way you could test for negative flow in webdriver is by using a try and catch..

In your case,

boolean buttonFound=false;
try
{ 
    new WebDriverWait(driver,10).until(ExpectedConditions.visibilityOfElementLocated(By.id("button")));

    buttonFound=true;

}catch(Exception e)
{
    System.out.println("The Button isn't present. Exiting!!");
    driver.findElement(By.linkText("Logout")).click();
}

if(buttonFound)
{
  //positive flow
}

here it'l wait for 10 secs for visibility of element,

• if found, buttonFound is set to true,hence positive flow is executed

• if not found, the message in catch clause will be displayed and logout link will be clicked
