Test Code Help!

We had a developer write an apex plugin to use in a flow but he didn't write any test for code and now my overall code coverage is less than 75% so I can't deploy anything via a changeset.  Below is the code.  Any help is appreciated.

global class mLSendEmail implements Process.Plugin {
    
    global Process.PluginResult invoke(Process.PluginRequest request) { 
        
        // Get the subject of the Chatter post from the flowgj
        //String emailS = (String) request.inputParameters.get('emailListString');
        String campaignId = (String) request.inputParameters.get('campaignId');
        String tempId = (String) request.inputParameters.get('emailTempId');
        //system.debug(idS);
        String userIdVar = UserInfo.getUserId();
        //List<String> emailList = emailS.split(', ');
        
        User userObject = [SELECT Name, Email
                           FROM User
                           WHERE Id = :userIdVar.left(15)
                           LIMIT 1]; //(String) request.inputParameters.get('userName');
        
        List<CampaignMember> test = [SELECT ContactId, CampaignId
                                     FROM CampaignMember
                                     WHERE CampaignId = :campaignId];
        
        List<Contact> contacts = [SELECT Id, Name, Email 
                                  FROM Contact 
                                  WHERE Id IN (SELECT ContactId 
                                               FROM CampaignMember 
                                               WHERE CampaignId = :campaignId AND ContactId != null)
                                  ];
        
        List<Lead> leads = [SELECT Id, Name, Email 
                            FROM Lead
                            WHERE Id IN (SELECT LeadId 
                                         FROM CampaignMember 
                                         WHERE CampaignId = :campaignId AND LeadId != null)
                            ];
        system.debug('EMAIL TEMPLATE ID: ' + tempId);
        system.debug('VALUE OF CONTACTS: ' + contacts);
        List<Messaging.SingleEmailMessage> mails = 
  new List<Messaging.SingleEmailMessage>();
        if (!contacts.isEmpty()) {
            system.debug('mLSendEmail.cls - contacts != null');
            for (integer i = 0; i <= contacts.size()-1; i++) {
                Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                mail.setTemplateId(tempId);
                mail.setReplyTo(userObject.Email);
                mail.setSenderDisplayName(userObject.Name);
                mail.setTargetObjectId(contacts.get(i).Id);
                mails.add(mail);
           }
        } else if (!leads.isEmpty()) {
            system.debug('mLSendEmail.cls - leads != null');
            for (integer i = 0; i <= leads.size()-1; i++) {
                Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                mail.setTemplateId(tempId);
                mail.setReplyTo(userObject.Email);
                mail.setSenderDisplayName(userObject.Name);

                mails.add(mail);
            }
        } else {
            system.debug('mLSendEmail.cls - else');
        }
  Messaging.sendEmail(mails);
        
        
        
        
        // return to Flow
        Map<String,Object> result = new Map<String,Object>(); 
        return new Process.PluginResult(result); 
        
    } 
    
    global Process.PluginDescribeResult describe() { 
        Process.PluginDescribeResult result = new Process.PluginDescribeResult(); 
        result.Name = 'Marketing Email Plugin';
        result.Tag = 'ML Email';
        result.inputParameters = new 
           List<Process.PluginDescribeResult.InputParameter>{
               new Process.PluginDescribeResult.InputParameter('emailTempId',
               Process.PluginDescribeResult.ParameterType.STRING, true),
               new Process.PluginDescribeResult.InputParameter('campaignId',

Please try this
  
@isTest(SeeAllData=True)
                        
private class mLSendEmailTest {

    static testmethod void mLSendEmailTests() {
      
        mLSendEmail plugin = new mLSendEmail();
        Map<String,Object> inputParams = new Map<String,Object>();
		
		User userObject = [SELECT Name, Email FROM User LIMIT 1]; // or you can mention your own user
		System.runAs(userObject)
		{
		
		Id CampaignMemberRec = [SELECT ContactId, CampaignId FROM CampaignMember LIMIT 1].CampaignId;
		String emailTempId = ''; // Add value between quotes
		
        InputParams.put('campaignId', CampaignMemberRec);
		InputParams.put('emailTempId', emailTempId);

        Process.PluginRequest request = new Process.PluginRequest(inputParams);           
        
        plugin.invoke(request);
		}
    } 
}

Hi ,

Please use below test class. Before you use modify on line 15 ( mention record id of email tempate ) 
If you face any issues please let me know. 
@isTest(SeeAllData=True)
                        
private class mLSendEmailTest {

    static testmethod void mLSendEmailTests() {
      
        mLSendEmail plugin = new mLSendEmail();
        Map<String,Object> inputParams = new Map<String,Object>();
		
		User userObject = [SELECT Name, Email FROM User LIMIT 1]; // or you can mention your own user
		Run.As(userObject)
		{
		
		CampaignMember CampaignMemberRec = [SELECT ContactId, CampaignId FROM CampaignMember LIMIT 1].CampaignId;
		String emailTempId = ''; // Add value between quotes
		
        InputParams.put('campaignId', CampaignMemberRec);
		InputParams.put('emailTempId', emailTempId);

        Process.PluginRequest request = new Process.PluginRequest(inputParams);           
        
        plugin.invoke(request);
		}
    } 
}

Sorry for typo error

Please try below code ( As I dont have your code base so I can not validate the syntax) 
@isTest(SeeAllData=True)
                        
private class mLSendEmailTest {

    static testmethod void mLSendEmailTests() {
      
        mLSendEmail plugin = new mLSendEmail();
        Map<String,Object> inputParams = new Map<String,Object>();
		
		User userObject = [SELECT Name, Email FROM User LIMIT 1]; // or you can mention your own user
		System.runAs(userObject)
		{
		
		CampaignMember CampaignMemberRec = [SELECT ContactId, CampaignId FROM CampaignMember LIMIT 1].CampaignId;
		String emailTempId = ''; // Add value between quotes
		
        InputParams.put('campaignId', CampaignMemberRec);
		InputParams.put('emailTempId', emailTempId);

        Process.PluginRequest request = new Process.PluginRequest(inputParams);           
        
        plugin.invoke(request);
		}
    } 
}

Hi ,

Seems line 10 is getting the inactive user. can you please replace the line #10 with below and see if this brings in active user and it works well.

User userObject = [SELECT Name, Email FROM User Where IsActive=true LIMIT 1];
