Data Integration Specialist- Level 4- Failed Tests of Apex Callouts

Guys-

I am testing an apex class (projectCalloutService). I took a different approach and made some class variables static because to avoid having to pass any parameters to queueable interface ( just to try it out). However, my test methods assertion failed in projectCalloutServiceTest class. I use VScode for my dev work and I tried to debug using Apex replay debugger and found out that my Static Variables of the projectCalloutService class becomes null and I dont understand why. Any help is appreciated and most likely I am making a dumb mistake somewhere.. thanks in advance!
  
public class ProjectCalloutService {
    static Opportunity opportunityObj;
    static Opportunity opp ;
    
    
    @InvocableMethod(label='Post Opportunity To PMS' description='Synchronize Outbound Project Data')  
    public static void PostOpportunityToPMS(List<Id> opportunityIds) {
        Opportunity opp = [SELECT Amount,CloseDate,Id,Name,StageName,Account.Name FROM Opportunity WHERE Id =: opportunityIds.get(0)] ; 
        Opportunity opportunityObj;
        ID newJobId = System.enqueueJob(new QueueablePMSCall());
        System.debug(newJobId);
    }

        gen.writeStartObject();
        gen.writeStringField('opportunityId', opp.Id);
        gen.writeStringField('opportunityName', opp.Name);
        gen.writeStringField('accountName', opp.account.Name);

Use this code 
  
public class ProjectCalloutServiceMockFailure implements HttpCalloutMock {

    public HttpResponse respond(HttpRequest req) {
        HttpResponse resp = new HttpResponse();
        resp.setHeader('Content-Type', 'application/json');
        resp.setStatusCode(400);
        resp.setStatus('Bad Request');
        return resp;
    }
}
  
public class ProjectCalloutServiceMock implements HttpCalloutMock {

    public HttpResponse respond(HttpRequest req) {
        HttpResponse resp = new HttpResponse();
        resp.setHeader('Content-Type', 'application/json');
        resp.setStatusCode(201);
        resp.setStatus('Created');
        return resp;
    }
}
  
@isTest
private class ProjectCalloutServiceTest {

    @TestSetup
    private static void setup() {
        ServiceTokens__c st = new ServiceTokens__c(
                name = ProjectCalloutService.PROJECT_SERVICE_TOKEN_NAME,
                Token__c = 'test-service-token'
        );
        insert st;
    }

    private static testMethod void testFailure() {
        Opportunity opp = createOpportunity();

        Test.startTest();
        Test.setMock(HttpCalloutMock.class, new ProjectCalloutServiceMockFailure());
        ProjectCalloutService.postOpportunityToPMS(new List<Id>{opp.Id});
        Test.stopTest();

        System.assertEquals('Resubmit Project', queryOpportunity(opp.Id).StageName);
    }

    private static testMethod void testSuccess() {
        Opportunity opp = createOpportunity();

        Test.startTest();
        Test.setMock(HttpCalloutMock.class, new ProjectCalloutServiceMock());
        ProjectCalloutService.postOpportunityToPMS(new List<Id>{opp.Id});
        Test.stopTest();

        System.assertEquals('Submitted Project', queryOpportunity(opp.Id).StageName);
    }

    private static Opportunity createOpportunity() {

        return opp;
    }

    private static Opportunity queryOpportunity(Id oppId) {
        return [SELECT StageName FROM Opportunity WHERE Id =: oppId LIMIT 1];
    }
}

Thanks but I replaced my code with yours and its still failing with the same error. Could you please share your ProjectCalloutService class code ?

I am also stuck with this challenge, however i am getting an error 'Methods defined as TestMethod do not support Web service callouts'. I am unable to identify the area of my code where i need to update. Below are my code:

@IsTest
public class ProjectCalloutServiceMock implements HttpCallOutMock{
   //Implement http mock callout here
    public HttpResponse respond(HttpRequest req)
    {
        HttpResponse res = new HttpResponse();
        res.setHeader('Content-Type', 'application/json');
        res.setStatus('OK');
        res.setStatusCode(201);
        return res;
    }
}

@Istest
public class ProjectCalloutServiceMockFailure implements HttpCallOutMock {
   //Implement http mock callout failure here
