Connecting Selenium Test to AWS Desktop Browser through cooperate proxy

I am trying to connect to the AWS device farm for desktop browser testing with Selenium 4 through a cooperate proxy, with no luck.
Here is the code I am using:

As you can see, I used the ApacheHttpClient as HTTPClient for the AWS DeviceFarmClient, so I can authenticate with the cooperate proxy - which works like a charm. I get the testGridUrl, which I can use in the second step to send commands via the RemoteWebDriver to the AWS Desktop Browser.
This is where the problems start. I use the OkHttpClient (recommended by Selenium) as HTTPClient for the RemoteWebDriver - here also to enable proxy authentication (which I think is not possible with the built in HTTPClient).
But when the test is run, I get a class cast exception - it seems the okHttpCLient cannot be cast to HttpClient.
java.lang.ClassCastException: class okhttp3.OkHttpClient cannot be cast to class org.openqa.selenium.remote.http.HttpClient (okhttp3.OkHttpClient and org.openqa.selenium.remote.http.HttpClient are in unnamed module of loader 'app')

Did anyone use a proxy for connection to the AWS DeviceFarm before with Selenium 4 and can give me some hints on how to procede (replace the HTTPClient? Cast possible?)
All the best, Pita.

"mvn test" 0 tests run - spring + cucumber + junit5

I have a test project where I'm trying to setup e2e api tests using rest-assured. Tests run fine if I run them from the feature files, however, when I try to run them with maven, 0 tests run. I believe there is something funky with my pom.xml but I can't figure it out...
My project structure looks like:this

I'm not really familiar with Spring though so I'm pretty sure I'm not using it correctly in my ApiTestStepDef.java

private RequestSpecification request;
private User user;
private User responseBody;
#Autowired
private RestAssuredClient restAssuredClient;
#Given("{string} endpoint")
public void setBaseUsersURI(String url){

}
#When("user posts request with details {string} {string} {string}")
public void sendRequest(String name, String gender, String status){
user = new User(name, gender, Helper.createRandomEmail(), status);
response =
request.given().log().all().
body(user).
when().
post().
then().log().all().
extract().response();
}
#Then("response status code is {int} and response contains correct user details")
public void checkResponseStatusCode(int statusCode){
response.then().spec(restAssuredClient.createResSpec(statusCode));
responseBody = response.getBody().as(User.class);
Assertions.assertEquals(user.getGender(), responseBody.getGender());
Assertions.assertEquals(user.getStatus(), responseBody.getStatus());
Assertions.assertEquals(user.getEmail(), responseBody.getEmail());
Assertions.assertEquals(user.getName(), responseBody.getName());
}
}

}
}

#SelectClasspathResource("src/test/resources/example")
Typically src/test/resources is not part of the classpath.
After running mvn test have a look at target/test-classes to understand the structure of what is on the classpath.

I have done some research and I figured it might have something to do mith mixing up JUnit4 and JUnit5 features which leads to maven surefire plugin not running tests. However I can't find where those leftover JUnit4 features might be.
I'd appreciate any help.

As pointed out by other comments and answers I had residual JUnit4 dependencies due to test containers. I was able to fix the issue by explicitly setting JUnit5 as a dependency for maven surefire plugin like so :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M5</version>
<dependencies>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter</artifactId>
<version>5.8.2</version>
</dependency>
</dependencies>
</plugin>

The Junit4 is available because of Testcontainer dependency.
Testcontainers have a dependency on Junit4 and have it available by default.
You might also encounter the following issue in few cases:
IDE's detects the test cases written in Junit4 format but in sometime in case you make the test classes and methods package-private, they don't detect it.
I am not sure if they would be removing it in further releases but they do have Junit5 support which should resolve the issue

WebSocket with embedded Tomcat is 404

I made two classes:
Main class with embedded Tomcat(8.5.20)
ServerEndpoint of Websocket
I run the main class on IntelliJ IDEA
and run this JavaScript: new WebSocket('ws://localhost:8080/ws')
in the console of Google Chrome.
I expected the response code is 200, but actually it is 404.
How can I fix this?
Main class:
package webapp;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.startup.Tomcat;
import javax.servlet.ServletException;
import java.io.File;
public class Main {
private static final String STATIC_DIR = "src/main/static/";
public static void main(String[] args) throws ServletException, LifecycleException {
Tomcat tomcat = new Tomcat();
tomcat.setPort(8080);
File staticDir = new File(STATIC_DIR);
tomcat.addWebapp("/", staticDir.getAbsolutePath());
tomcat.start();
tomcat.getServer().await();
}
}
ServerEndpoint:
package webapp.websocket;
import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;
#ServerEndpoint("/ws")
public class SampleWebSocket {
#OnOpen
public void onOpen(Session session) {
System.out.println("open");
}
#OnClose
public void onClose(Session session) {
System.out.println("close");
}
#OnMessage
public String onMessage(String text) {
System.out.println("message:" + text);
return "Server:" + text;
}
}
Thank you.

I found a solution.
This question is dupricated.
I read Got 404 error on tomcat 7.0.47 websocket and editted my pom.xml.
Following is the whole of my pom.xml.
<project xmlns="http://maven.apache.org/POM/4.0.0"

</dependency>
<dependency>
<groupId>javax.websocket</groupId>
<artifactId>javax.websocket-api</artifactId>
<version>1.1</version>
</dependency>
</dependencies>
</project>

Just add the following dependency to pom.xml
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-websocket</artifactId>
<version>8.5.20</version>
</dependency>

What solved the issue for me was switching from the javax.websocket-api dependency to the Tomcat-specific tomcat-embed-websocket dependency instead and switching all my imports (ServerEndpoint, onMessage, etc.) to the Tomcat-specific jakarta.websocket.* packages instead of the javax.websocket.x packages.
Here is the endpoint code that worked for me -- notice that there are no javax.websocket imports and instead I have jakarta.websocket imports:
import java.io.IOException;
import jakarta.websocket.EncodeException;
import jakarta.websocket.OnMessage;
import jakarta.websocket.Session;
import jakarta.websocket.server.ServerEndpoint;
#ServerEndpoint("/echo")
public class EchoEndpoint {
// Implementation.
#OnMessage
public void onMessage(
Session session,
String message)
throws
IOException,
EncodeException {
// Send the same message back.
session.getBasicRemote().sendText(message);
}
}
And my pom.xml file dependencies:
<!-- https://mvnrepository.com/artifact/org.apache.tomcat.embed/tomcat-embed-core -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>10.1.0-M8</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.tomcat.embed/tomcat-embed-websocket -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-websocket</artifactId>
<version>10.1.0-M8</version>
</dependency>
As far as I can tell, the pom.xml should not contain the javax.websocket dependency at all, to ensure there are no collisions/clashes between that one and the Tomcat-specific tomcat-embed-websocket dependency.

ClassNotFoundException when trying to bulk load into titan using a Java MapReduce job

We're currently trying to bulk load some files from HDFS into titan using a map reduce job and the titan dependencies. However, we're running into an issue once the map jobs start where it can't find a tinkerpop class. This is the error:
java.lang.ClassNotFoundException: org.apache.tinkerpop.gremlin.structure.Vertex
I read somewhere that Titan 1.0.0 is only compatible with Tinkerpop 3.0.1-incubating, so that's what our versions are for dependencies.
It might help to see our pom.xml and code

I'd suggest that you look into creating an uber-jar that contains all of your project dependencies. Since you're using Apache Maven for your build, you use the Apache Maven Assembly Plugin or the Apache Maven Shade Plugin.
