I tried to import an Apex trigger and Class I created so that when an opportunity is created a quote is created, with the opportunity's product if it has one. We said me that we have to have 75%code coverage to import it. So I have to create an Apex test. But above my trigger and my class, it is already written 100%, so I don't understand.

Also, my Apex test is only 62%... And I don't know how to increase it.

Hi,

After several days of work and a lot of help I managed to create an Apex Class and an Opportunity Trigger to create a quote when an opportunity is created and a quote line item if the opportunity has an opportunity line item. 
I have tried to create a Test Class to manage to import it in my production since then bur the code coverage is only of 61%, I must have 75%.

How can I have a bigger code coverage ? Here's my codes. Hope you could help!

I created with a lot of help a trigger with its Apex Class in a sandbox. Now I would like to have it in my production to really use it. 
How can I do that ? 

Please help me, I spend a lot of time creating these, I cannot have done it for nothing. Thank you in advance.

I would like to create a trigger which can insert a quote and a quotelineitem when I clone an opportunity with its product. I tried many Trigger.
If someone can help me understand the problem it would be awesome! I spent already a few days on it...

trigger FacturationCreator on Opportunity (after insert, after update) {
for (Opportunity o : Trigger.new) {
if (o.Type == 'Event') {

//Opportunity oppId=[select id from Opportunity where id=:q.OpportunityId];
List<OpportunityLineItem> opplines=[select id, quantity, PriceBookEntry.Product2Id, UnitPrice, PricebookentryId
from OpportunityLineItem where OpportunityId=:o.id];
 for(OpportunityLineItem oppline:opplines){ 
List <Quote> factList = new List<Quote>();

Quote q = new Quote();
q.name = 'Quote-' + o.name;
q.Montant_1_re_ch_ance__c = 1000;
q.Date_de_Facture__c = o.CloseDate;
q.Date_1_re_ch_ance__c = o.CloseDate;
q.opportunityId = o.id;
factList.add(q);
insert q;


List<Quote> qList=[select id from Quote where opportunityId=:o.id];
for(Quote q:qList){ 
QuoteLineItem qli = new QuoteLineItem();
qli.quoteId = q.Id;
qli.UnitPrice = oppline.UnitPrice;
qli.Product2Id = oppline.PriceBookEntry.Product2Id;
qli.Quantity = oppline.Quantity;
qli.PriceBookentryid = oppline.PriceBookentryId;
insert qli;}

}
        }
    }
}

I tried to import an Apex trigger and Class I created so that when an opportunity is created a quote is created, with the opportunity's product if it has one. We said me that we have to have 75%code coverage to import it. So I have to create an Apex test. But above my trigger and my class, it is already written 100%, so I don't understand.

Also, my Apex test is only 62%... And I don't know how to increase it.

I created with a lot of help a trigger with its Apex Class in a sandbox. Now I would like to have it in my production to really use it. 
How can I do that ? 

Please help me, I spend a lot of time creating these, I cannot have done it for nothing. Thank you in advance.

I would like to create a trigger which can insert a quote and a quotelineitem when I clone an opportunity with its product. I tried many Trigger.
If someone can help me understand the problem it would be awesome! I spent already a few days on it...

trigger FacturationCreator on Opportunity (after insert, after update) {
for (Opportunity o : Trigger.new) {
if (o.Type == 'Event') {

//Opportunity oppId=[select id from Opportunity where id=:q.OpportunityId];
List<OpportunityLineItem> opplines=[select id, quantity, PriceBookEntry.Product2Id, UnitPrice, PricebookentryId
from OpportunityLineItem where OpportunityId=:o.id];
 for(OpportunityLineItem oppline:opplines){ 
List <Quote> factList = new List<Quote>();

Quote q = new Quote();
q.name = 'Quote-' + o.name;
q.Montant_1_re_ch_ance__c = 1000;
q.Date_de_Facture__c = o.CloseDate;
q.Date_1_re_ch_ance__c = o.CloseDate;
q.opportunityId = o.id;
factList.add(q);
insert q;


List<Quote> qList=[select id from Quote where opportunityId=:o.id];
for(Quote q:qList){ 
QuoteLineItem qli = new QuoteLineItem();
qli.quoteId = q.Id;
qli.UnitPrice = oppline.UnitPrice;
qli.Product2Id = oppline.PriceBookEntry.Product2Id;
qli.Quantity = oppline.Quantity;
qli.PriceBookentryid = oppline.PriceBookentryId;
insert qli;}

}
        }
    }
}
