My class:
global class autoCompleteForAccount

        String userId = UserInfo.getUserId();
        List<User> conId = Database.query('SELECT ContactId from User where Id=\'' + userId + '\'');
        
        if(loginUserProfile == System.Label.Customer_Community_Plus_Profile)
        {
            String commaSepratedList = '';
            List<Shared_Contact__c> sharedCon = [SELECT Account__c FROM Shared_Contact__c where contact__c =:conId[0].ContactId];
            if(sharedCon.size()>0)

                        //listIds.add(sc.Account__c);
                        if(sc.Account__c != NULL) 
                            commaSepratedList += '\''+ sc.Account__c  + '\',' ;
                        
                    }
                commaSepratedList = commaSepratedList.subString(0,commaSepratedList.length()-1);
            }

My test class:
@istest
global class Test_autoCompleteForAccount
{
    global static testMethod void testClass()
    {
        account acc = new account(name='TestAccount',Company_Name__c='TestAccount');
        insert acc;
         Test.startTest();
        sObject[] s1 = autoCompleteForAccount.findSObjects( 'Test', '');
        Test.stopTest();
    }
