apex class test need help

Hi there, 

I did a test class for my controller but I can't find my error, could you please help me? I'll give you an example of my controller and my test class.

Controller : 

public with sharing class AdvancedAnalyseController {
    @AuraEnabled
    public static void cloneThisAnalyse(Id analyseId, Integer nombreA) {
        String queryAnalyse = 'SELECT Id, ';
        queryAnalyse += buildCustomFieldsQuery(Analyse__c.getSObjectType());
        queryAnalyse = queryAnalyse.removeEnd(', ') + ' FROM Analyse__c WHERE Id = \'' + analyseId + '\'';
        mDebugUntruncated(queryAnalyse);
        List<Analyse__c> aList = Database.query(queryAnalyse);
        if (aList.isEmpty()) {
            AuraHandledException ex = new AuraHandledException('NO_ANALYSE');
            ex.setMessage('NO_ANALYSE');
            throw ex;
        }
        List<Analyse__c> analyseClone = new List<Analyse__c>();
         for (Integer i=0; i<nombreA; i++) {
            Analyse__c newAnalyse = aList.get(0).clone();
            newAnalyse.Clone__c = true;
            analyseClone.add(newAnalyse);
         }
        insert analyseClone;
        
    }
    @TestVisible
    private static String buildAllFieldsQuery(Schema.SObjectType targetSObjectType) {
        Map<String, Schema.SObjectField> fieldMap = targetSObjectType.getDescribe().fields.getMap();
        String query = '';
        for (String key : fieldMap.keySet()) {
            Schema.SObjectField field = fieldMap.get(key);
            Schema.DescribeFieldResult result = field.getDescribe();
            query += result.getName() + ', ';
        }
        return query.removeEnd(', ');
    }
    @TestVisible
    private static String buildCustomFieldsQuery(Schema.SObjectType targetSObjectType) {
        Map<String, Schema.SObjectField> fieldMap = targetSObjectType.getDescribe().fields.getMap();
        String query = '';
        for (String key : fieldMap.keySet()) {
            Schema.SObjectField field = fieldMap.get(key);
            Schema.DescribeFieldResult result = field.getDescribe();
            if (result.isCustom()) {
                query += result.getName() + ', ';
            }
        }
        return query.removeEnd(', ');
    }
    public static void mDebugUntruncated(String sMsg) {
        for (Integer i = 0; i < sMsg.length(); i=i+300) {
            Integer iEffectiveEnd = (i+300 > (sMsg.length()-1) ? sMsg.length()-1 : i+300);
            System.debug(sMsg.substring(i,iEffectiveEnd));
        }
    }

I'll start by saing that your tests don't really do much and aren't tests that I would like to see in my org.  Each test should include assert methods that actually test that you're methods are doing what they expect and just checking that a list isn't null is not a good test.  Additionally, you never said how your tests are erroring, just that they are.  I'd start by reworking your tests so that they actually have the expected data being asserted.  I've taken the liberty of refactoring / reformatting your main code to help with this discussion.
  
public with sharing class AdvancedAnalyseController {
    public static String NO_ANALYSE = 'NO_ANALYSE'
    @AuraEnabled
    public static void cloneThisAnalyse(Id analyseId, Integer nombreA) {
        List<String> query = new List<String> {
            'select ' + buildCustomFieldsQuery(Analyse__c.getSobjectType()),
            'from ' + Schema.sObjectType.Analyse__c.getName(),
            'where Id = \'' + analyseId + '\''
        }
        
        List<Analyse__c> aList = Database.query(String.join(query, ' '));
        
        if (aList.isEmpty()) {
            throw new AuraHandledException(NO_ANALYSE);
        }
        
        List<Analyse__c> clones = new List<Analyse__c>();
        
        for (Analyse__c analyse : aList) {
            Analyse__c newAnalyse = analyse.clone();
            newAnalyse.Clone__c = true;
            clones.add(newAnalyse);
        }
        
        insert clones;
    }
    
    @TestVisible
    private static String buildAllFieldsQuery(Schema.SObjectType targetSObjectType) {
        Map<String, Schema.SObjectField> fieldMap = targetSObjectType.getDescribe().fields.getMap();
        List<String> fields = new List<String>();
        fields.addAll(fieldMap.keySet());
        
        return String.join(fields, ',');
    }
    
    @TestVisible
    private static String buildCustomFieldsQuery(Schema.SObjectType targetSObjectType) {
        Map<String, Schema.SObjectField> fieldMap = targetSObjectType.getDescribe().fields.getMap();
        List<String> fields = '';
        
        for (String key : fieldMap.keySet()) {
            Schema.DescribeFieldResult result = fieldMap.get(key).getDescribe();
            
            if (result.isCustom()) {
                fields.add(result.getName());
            }
        }
        return String.join(fields, ',');
    }   
}

Then you can write your tests as follows.  You'll want to add tests that cover all the facets and all the conditional logic you have in place.  You'll also want to write explict tests covering the other methods.  I remove the debug one since it shouldn't go to production and is not something you can validly test.
