How to improve the coverage of this test class in Apex? - salesforce

Question

I have created a test class with 51% code coverage till line no 34.
Further, I tried to satisfy if condition but I couldn't. Now I am not getting how to do with 100% code coverage.
Here is the Apex class:
public class AssignProjectController {
public String CaseIds;
public String status {get;set;}
public List<Project__c> activeProjects {get;set;}
public String keyWordSearched {get;set;}
public Id projectId {get;set;}
public AssignProjectController (){
CaseIds = ApexPages.currentPage().getParameters().get('id');
}
public void getProjects(){
status = '';
String searchQuery = 'FIND \'' + keyWordSearched + '*\' IN ALL FIELDS RETURNING Project__c (id,Name,Description__c where Status__c =\'Active\')';
try{
List<List<Project__c >> searchList = search.query(searchQuery);
activeProjects = searchList[0];
if(activeProjects.size() == 0) status = 'No search result found.';
}catch(Exception ex){
system.debug('ex..'+ex.getMessage());
}}}
public PageReference assignProjectToCases(){
List<Case__c> customSettingList = Case__c.getall().values();
List<String> settingRecordTypeList = new List<String>();
for(Case__c caseObj:customSettingList){
settingRecordTypeList.add(caseObj.Name);
}
List<RecordType> recordTypeListData = [SELECT Id FROM RecordType WHERE SObjectType = 'Case' and Name In : settingRecordTypeList];
if(CaseIds != null){
List<String> caseIDList = new List<String>();
caseIDList = CaseIds.split(',');
if([Select id from Case where Id In : caseIDList and RecordType.Id NOT In : recordTypeListData].size() > 0){
status = 'failed';
}else{
List<Case> cases = [Select id,Project__c,RecordType.Name from Case where Id In : caseIDList and RecordType.Id In : recordTypeListData];
if(cases.size() > 0){
for(case caseOb: cases){
caseOb.Project__c = projectId ;
}
try{
update cases ;
status = 'Changes are scheduled';
}catch(Exception ex){
system.debug('AssignProjectController :::'+ex.getMessage());
status = 'Something Went Wrong';
}}}}
return null;
}}
Here is the test class- which I tried to resolve
#isTest public class TestAssignProjectController {
public static Project__c insertProject(){
Project__c proObj = new Project__c();
proObj.Name = 'testProject';
proObj.Status__c = 'Active';
proObj.Description__c = 'for testing';
proObj.Internal_Email_Alias__c = 'a#test.com';
return proObj;
}
public static Account getAccount(){
Account accoObj = new Account();
accoObj.Name = 'testAcc';
accoObj.Location__c = 'testLocation';
accoObj.Type = 'CM';
accoObj.BillingCountry = 'United States';
return accoObj;
}
public static Contact insertContact(Account accObj){
Contact conObj = new Contact();
conObj.FirstName = 'test';
conObj.LastName = 'testLastname';
conObj.AccountId = accObj.Id;
conObj.Email = 'abc#gmail.com';
return conObj;
}
public static Id getTechTypeId(){
return Schema.SObjectType.Case.getRecordTypeInfosByName().get('Tech ').getRecordTypeId();
}
public static Case insertCase(String conId, String proId){
Case caseObj = new Case();
caseObj.Project__c = proId;
caseObj.ContactId = conId;
caseObj.Status = 'Open';
caseObj.Inquiry_Type__c = 'All';
caseObj.Subject = 'TestSubject';
caseObj.Description = 'TestDescription';
caseObj.Case_Is_Reopened__c = false;
caseObj.RecordTypeId = getTechTypeId();
return caseObj;
}
public static testmethod void testMethodExecution(){
AssignController asigncon = new AssignController ();
Project__c proObj = insertProject();
insert proObj;
System.assertEquals(proObj.Status__c,'Active');
Account accObj = getAccount();
insert accObj;
System.assertNotEquals(accObj.Id,null);
Contact conObj = insertContact(accObj);
insert conObj;
System.assertNotEquals(conObj.Id,null);
Case caseObj = insertCase(conObj.Id, proObj.Id);
insert caseObj;
system.debug(caseObj);
//Set baseURL & case ID
PageReference pageRef = Page.Assign;
pageRef.getParameters().put('id',caseObj.id+',');
AssignController asigncon1 = new AssignController ();
asigncon1.getProjects();
asigncon1.assignProjectToCases();
}}

If you are referring if(cases.size() > 0) this statement, then surely there is problem of inserting the case. Make sure that insert caseObj; is working and inserts data in Salesforce backend.
If there is no data in case object, the test method cannot cover the if statement.
