Here is how I would do it (please ignore worry Logger class calls):
public boolean isElementExist(By by) {
int count = driver.findElements(by).size();
if (count>=1) {
Logger.LogMessage("isElementExist: " + by + " | Count: " + count, Priority.Medium);
return true;
}
else {
Logger.LogMessage("isElementExist: " + by + " | Could not find element", Priority.High);
return false;
}
}
public boolean isElementNotExist(By by) {
int count = driver.findElements(by).size();
if (count==0) {
Logger.LogMessage("ElementDoesNotExist: " + by, Priority.Medium);
return true;
}
else {
Logger.LogMessage("ElementDoesExist: " + by, Priority.High);
return false;
}
}
public boolean isElementVisible(By by) {
try {
if (driver.findElement(by).isDisplayed()) {
Logger.LogMessage("Element is Displayed: " + by, Priority.Medium);
return true;
}
}
catch(Exception e) {
Logger.LogMessage("Element is Not Displayed: " + by, Priority.High);
return false;
}
return false;
}
