How to deal with search that does not give any results on a webpage?



I wrote a program with some help from a few other Stack Overflow members a few days ago, and I now had a new functionality question.



So here is my code:


// importing a bunch of packages

public class webSearch {
public webSearch() {

}

public WebDriver driver = new ChromeDriver();

public void openTestSite() {
//driver.navigate().to(the URL for the website);
driver.get("https://wonef.fr/try/");
driver.manage().window().maximize();
//Explicit wait is added after the Page load
WebDriverWait wait=new WebDriverWait(driver,20);
wait.until(ExpectedConditions.titleContains("WoNeF"));
}

public void enter(String word) {

WebElement query_editbox =
driver.findElement(By.id("query"));
query_editbox.sendKeys(word);
//AutoComplete is happening even after sending the Enter Key.
// So, Value needs to be selected from the autocomplete
WebDriverWait wait=new WebDriverWait(driver,20);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@class='autocomplete']/div")));
List<WebElement> matchedList=driver.findElements(By.xpath("//div[@class='autocomplete']/div"));

// System.out.println(matchedList.size());
for(WebElement element : matchedList){
if(element.getText().equalsIgnoreCase(word)){
element.click();
}
}
query_editbox.sendKeys(Keys.RETURN);
}

public void getText(String name) throws IOException {
WebDriverWait wait=new WebDriverWait(driver,20);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@id='mid']/div")));
WebElement result=driver.findElement(By.id("mid"));
Writer writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(name), "utf-8"));
writer.write(result.getText());
writer.close();
}



}



It basically opens a website, types in a word, presses enter, and then saves whatever is returned to a text file.



My question is how do I deal with the program when a word is typed in but there isn't a single hit in the search. This always causes the following error in my code:


Exception in thread "main" org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.xpath: //div[@class='autocomplete']/div (tried for 20 second(s) with 500 milliseconds interval)

You could catch the exception and then do (or not do) something based on it.

I do not see any chrome path command in your code

I do not see any auto complete though. Why do you need that string prior of clicking on enter button. I mean you already have the key , why would selenium returns it. If it is available in DOM then only Selenium can help.

What I am confused about is one thing in my code? The element is not going to even be in the matched list if nothing shows up in the search bar, right? That was my intention when I wrote it and asked about it before.

I have a main method in the engine class which has the chrome driver access given to it. Also @Kayaman, thanks for the suggestion, however, I am not sure which exception I would catch.

When you entered some unavailable word, then autocomplete is not happening and hence TimeoutException is throwing. You need to handle this exception using try catch block.So, that your execution will be continued without any Exception. If you need to add some logic when the autocomplete is not happening, then you can handle those logic in catch block.


TimeoutException



If the AutoComplete is not displayed within 20 seconds, then we can assume that entered value is invalid.



Please find the modified code:



enter Method:


public void enter(String word) {

WebElement query_editbox =
driver.findElement(By.id("query"));
query_editbox.clear();
query_editbox.sendKeys(word);

try{
//AutoComplete is happening even after sending the Enter Key.
// So, Value needs to be selected from the autocomplete
WebDriverWait wait=new WebDriverWait(driver,20);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@class='autocomplete']/div")));
List<WebElement> matchedList=driver.findElements(By.xpath("//div[@class='autocomplete']/div"));

// System.out.println(matchedList.size());
for(WebElement element : matchedList){
if(element.getText().equalsIgnoreCase(word)){
element.click();
}
}

}catch (TimeoutException e){
System.out.println("Invalid Word is entered");

}

query_editbox.sendKeys(Keys.RETURN);
}



Edit: To Address followup Question



I have added the clear action in enter method before entering the word.you can introduce some for loop in your main method in order to execute with different words


enter


String input={};

for(int i=0;i<input.length;i++){
webSrcapper.enter(input[i]);
webSrcapper.getText();
}



Sample with Array List:


ArrayList<String> list=new ArrayList<>();

list.add("Word1");
list.add("Word2");
list.add("Word3");

for(int i=0;i<input.length;i++){
webSrcapper.enter(list.get(i));
webSrcapper.getText();
}



You need to modify your webSearch class as below


public class webSearch {
public WebDriver driver;

public webSearch() {
ChromeOptions options = new ChromeOptions();
options.addArguments("headless");
driver=new ChromeDriver(options);
}



getText Method :


public void getText(String name) throws IOException {

try{
WebDriverWait wait=new WebDriverWait(driver,20);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@id='mid']/div")));
WebElement result=driver.findElement(By.id("mid"));
Writer writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(name), "utf-8"));
writer.write(result.getText());
writer.close();
}catch (TimeoutException e){
System.out.println("No Result is found for the requested word");

}

}





Thank you so much!! Sorry to bother you again, but I had one more question. Do you know how I can clear the search bar after entering one word? So, I have a for loop which goes through the words in an array, enters each word into the search bar, and saves the contents into a text file. So, do you know how I can clear the element each time?

Also, is there any way to do this without actually opening the chrome browser? I'm just wondering because that will be much more efficient.

@userNeedsHelp: I have updated the answer. Please check with the updated answer and you need to add query_editbox.clear(); before doing the sendkeys in enter Method

Thank you for the updates! I had previously done the for loop thing and am actually getting a new error. Can you please refer to the code above to see it?

@userNeedsHelp. If the invalid Word is searched, then it will not give any result.So, you need to use try catch blcok in your getText method as well. updated the answer

You can select your desired option using below code :


WebElement query_editbox = driver.findElement(By.id("query"));
query_editbox.sendKeys("bad");
String wordToBeSelected = "badge";
selectOptionFromDropdown(driver, wordToBeSelected);

private static void selectOptionFromDropdown(WebDriver driver, String wordToBeSelected) {
WebDriverWait wait=new WebDriverWait(driver,25);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector(".autocomplete div")));

List<WebElement> dropdownList = driver.findElements(By.cssSelector(".autocomplete div"));
WebElement desiredElement = dropdownList.stream()
.filter(element -> element.getAttribute("title").equals(wordToBeSelected))
.findFirst().get();
desiredElement.click();
}



Hope this helps you.





Thank you for your suggestion! I think I got this part working with your suggestion and @Subburaj's suggestion.

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given.

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM).
