Cannot invoke By not finding elements on the webpage

Im writing a selenium project from scratch using the PageObject.
The below code is failing because the selenium webdriver is not finding elements on the webpage .
This is the error i get :
java.lang.NullPointerException: Cannot invoke "org.openqa.selenium.SearchContext.findElement(org.openqa.selenium.By)" because "this.searchContext" is null
DriverBase.java :
In this class i setup the driver

System.out.println(username);
//wait.until(ExpectedConditions.visibilityOf(this.usernameTextBox));
usernameTextBox.clear();
passwordTextBox.clear();
usernameTextBox.sendKeys(username);
passwordTextBox.sendKeys(password);
submitButton.click();
//wait.until(ExpectedConditions.visibilityOf(this.tokenTextBox));
}
}
LoginPageTests.java :
In this class i write tests and i call methods from LoginPage.java Class

super();
}
LoginPage loginPage = new LoginPage();
#BeforeTest
public void setup() throws InterruptedException {
initialization();
}
#Test
public void login() {
loginPage.performLogin();
}
}

I found that i have to declare the pages in the before methods after the initilisation ()
public class LoginPageTest extends DriverBase {
public LoginPageTest() throws IOException {
super();
}
// here
LoginPage loginPage;
TokenPage tokenPage;
#BeforeTest
public void setup() throws InterruptedException {
initialization();
//here
loginPage = new LoginPage();
tokenPage = new TokenPage();
}
#Test
public void login() {
tokenPage = loginPage.performLogin();
}
}
This is just worked for me

Calling forEach on a stream causes java.lang.IllegalStateException

I have a program which does the following:
Stores a file name in Main method
Passes that file to the below method(StreamParser)from Main
Method StreamParser reads that file as Stream
StreamParser should return Stream
In main method when I call forEach on purchaseEventStream it gives an error in line
purchaseEventStream.forEach(purchaseEvent -> {

Why am i getting the error?

A stream in java is not a collection. It does not store data. You should create and return a collection from method parser() in class StreamParser and then create a stream from the returned collection.
I rewrote your StreamParser class to return a List.
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.List;
import java.util.stream.Collectors;
public class StreamParser {
public List<PurchaseEvent> parser(String fileName) throws IOException {
List<PurchaseEvent> purchaseEventStream = Files.lines(Paths.get(fileName))
.map(line -> {
String[] fields = line.split(",");
PurchaseEvent finalPurchaseEvent = new PurchaseEvent();
finalPurchaseEvent.setSessionId(fields[0]);
finalPurchaseEvent.setTimeStamp(fields[1]);
finalPurchaseEvent.setItemId(fields[2]);
finalPurchaseEvent.setPrice(fields[3]);
finalPurchaseEvent.setQuantity(fields[4]);
return finalPurchaseEvent;
})
.collect(Collectors.toList());
return purchaseEventStream;
}
}
And I changed your Main class accordingly.
import java.io.*;
import java.util.ArrayList;
import java.util.List;
public class Main {
public static void main(String[] args) throws IOException {
OutputStreamWriter outputStream = new OutputStreamWriter(new FileOutputStream("output1.txt"));
String file = "/Users/mohit/intern-mohit/yoochoose-buys.dat";
StreamParser streamParser = new StreamParser();
List<ReportGenerator> reports = new ArrayList<>();
PurchaseEventCount purchaseEventCount = new PurchaseEventCount();
QuantityPerSession quantityPerSession = new QuantityPerSession();
SessionCount sessionCount = new SessionCount();
reports.add(purchaseEventCount);
reports.add(sessionCount);
reports.add(quantityPerSession);
List<PurchaseEvent> purchaseEventStream = streamParser.parser(file);
purchaseEventStream.forEach(purchaseEvent -> {
for (ReportGenerator report : reports) {
report.generateReports(purchaseEvent);
}
});
reports.forEach(report -> {
try {
report.printReports(outputStream);
}
catch (IOException e) {
e.printStackTrace();

Mock an instance method call of another class that takes a URL and File object and writes a file to a HTTP connection

I'm trying to write UTs for a file called DocumentStoreAccessor.java. Here is the class below:

public class DocumentStoreAccessor {

public DocumentStoreAccessor() {

this.documentStoreClient = accessorComponent.provideDocumentStoreClient();
}
private int putContentsIntoS3(CreateUploadS3UrlResult createUploadS3UrlResponse,
#NonNull File file) {
int uploadStatusCode = 0;
try {
URL url = new URL(createUploadS3UrlResponse.getS3Url());
uploadStatusCode = new AWSS3Util().upload(url, file); //Instance comes from a util class
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {

}
return uploadStatusCode;
}
public String uploadFile(File file, DocumentFileExtension fileExtension) throws Exception {
String documentId = null;
CreateUploadS3UrlResult createUploadS3Urlresult = documentStoreClient.createUploadS3Url(new CreateUploadS3UrlRequest());
int putContentsStatusCode = putContentsIntoS3(createUploadS3Urlresult, file);

Inside this file I do new AWSS3Util().upload(url, file).

I want to make new AWSS3Util().upload(url, file) return a 200..
I'm unable to do so.. I keep getting a NullPointerException. Here is what I have for the past day:

return httpURLConnection;
}
};
final URL url = new URL("http://foo.io", "foo.io", 80, "", handler);
return url;
}
}
I'm unable to mock the URL class, so I followed a another Stackoverflow post..
The AWSS3Util cannot come through Dagger, it is a util class that we're all using so this must not change.
I'm not sure if I'm going in the right direction.. I've tried "spying" on that AWSS3Util class. I want this method to return a 200 or any status code of my choice to cover them in UTs by asserting a String return as seen in the example below
I can change the the upload method inside AWSS3Util to static if it helps UTs
Cannot use PowerMockito (this is a last resort)
Try incorporating Yan's comments:
#Test
void verifyCreateUploadS3UrlInvocation() throws Exception {
when(mockDocumentStoreClient.createUploadS3Url(dummyCreateUploadS3UrlRequest)).thenReturn(dummyCreateUploadS3UrlResult);
when(httpURLConnection.getOutputStream()).thenReturn(outputStream);
when(httpURLConnection.getResponseCode()).thenReturn(200);
when(awss3Util.upload(url, getDataToUpload())).thenReturn(200);
when(mockDocumentStoreClient.createDocument(dummyCreateDocumentRequest)).thenReturn(dummyCreateDocumentResult);
String id = classUnderTest.uploadFile(getDataToUpload(), DocumentFileExtension.XLSX);
assertEquals(id, "foo");
verify(mockDocumentStoreClient, times(1)).createUploadS3Url(dummyCreateUploadS3UrlRequest);
}
I get a 405 thrown when I specifically want it to send a 200, and therefore java.lang.Exception: Status code is: 405 thrown from my function.

Firstly I would change a little bit AWSS3Util, because reading binary files as string can lead to very interesting results.
import lombok.NonNull;
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
public class AWSS3Util {
private static final String PUT_REQUEST_METHOD = "PUT";
public int upload(#NonNull final URL url, #NonNull final File file) throws IOException {
HttpURLConnection connection = create(url);
try (BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file))) {
connection.setDoOutput(true);
connection.setRequestMethod(PUT_REQUEST_METHOD);
try (BufferedOutputStream bos = new BufferedOutputStream(connection.getOutputStream())) {
byte[] buffer = new byte[1024];
int len;
while ((len = bis.read(buffer)) > 0) {
bos.write(buffer, 0, len);
}
}
return connection.getResponseCode();
}
}
private HttpURLConnection create(URL url) throws IOException {
return (HttpURLConnection) url.openConnection();
}
}
Test for upload method could be like this:
import org.junit.jupiter.api.Test;
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLStreamHandler;
import java.nio.file.Files;
import static org.junit.jupiter.api.Assertions.assertArrayEquals;
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.when;
public class MyTest {
#Test
public void test() throws IOException {
final HttpURLConnection mockUrlCon = mock(HttpURLConnection .class);
URLStreamHandler stubUrlHandler = new URLStreamHandler() {
#Override
protected URLConnection openConnection(URL u) throws IOException {
return mockUrlCon;
}
};
URL url = new URL("http://foo.io", "foo.io", 80, "", stubUrlHandler);
when(mockUrlCon.getResponseCode()).thenReturn(200);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
when(mockUrlCon.getOutputStream()).thenReturn(outputStream);
File file = new File("c:\\anyFile.png");
int responseCode = new AWSS3Util().upload(url, file);
assertEquals(200, responseCode);
byte[] expectedBytes = Files.readAllBytes(file.toPath());
byte[] actualBytes = outputStream.toByteArray();
assertArrayEquals(expectedBytes, actualBytes);
}
}

I had to violate the second rule - I had to DependencyInject it via Dagger
package com.company.main.dagger.module;
import com.company.main.util.aws.s3.AWSS3Util;
import dagger.Module;
import dagger.Provides;
import javax.inject.Singleton;
#Module
public class AWSS3UtilModule {
#Provides
#Singleton
public static AWSS3Util provideAwss3Util() {
return new AWSS3Util();
}
}
and then in my component
import javax.inject.Singleton;
#Singleton
#Component(modules = {
ShipDocsDMSAccessorModule.class,
AWSS3UtilModule.class
})
public interface AccessorComponent {
ShipDocsDMS provideShipDocsDMSClient();
AWSS3Util provideAwss3Util();
}
and then in my main class
#Slf4j
#RequiredArgsConstructor
public class ShipDocsDMSAccessor {
private final ShipDocsDMS shipDocsDMSClient;
private final AWSS3Util awss3Util;
public ShipDocsDMSAccessor() {
AccessorComponent accessorComponent = DaggerAccessorComponent.create();
this.shipDocsDMSClient = accessorComponent.provideShipDocsDMSClient();
this.awss3Util = accessorComponent.provideAwss3Util();
}
.
.
.
.
and then in my test, I can freely mock AWSS3Util dependency and carry ahead and force out the required response.

How to Upload a file into web browser using Winium?

I know I can upload file to browser with many ways such as: AutoIt, Robot Class, and other ways(I tried them all and they worked most of time).
I got introduced to Winium and I would like to make the same test case with it, that is, upload a file to a browser using it, but I did not know what to do to switch between web driver to winium driver. Please help because I searched a lot for this trick but could not find any result
package testUtilities;
