emuelas Help needed to write a simple test method for Apex class to deploy in production
Hi ,
I have a simple Apex class that retrieves and updates data which i want to deploy to production.
Iam totally new to test classes/methods.
Please help me to write a simple test method for my Apex Class.
public with sharing class serpinv {
String pid = ApexPages.currentPage().getParameters().get('id');
Product_inventory__c po;
public serpinv(ApexPages.StandardController controller)
{
//retrieve record
this.po = (product_inventory__c)controller.getRecord();
}
public pagereference saveChanges()
{
//update record
update this.po;
product_serial__c ps=new product_serial__c(
serial_number__c=po.serial_number__c);
//insert and update record
insert ps;
ps.account__c=po.supidtest__c;
update ps;
po.serial_number__c=null;
po.warehouse__c=null;
po.bin__c=null;
po.orderpinv__c=null;
po.price__c=null;
update po;
Pagereference p = new PageReference('/'+ps.id);
p.setRedirect(true);
return p;
}
}
simple test method:
static testMethod void myTest() {
//how to parse throgh the controller
}
Tryout the test method given below:
static testMethod void myTest()
{
ApexPages.StandardController controller= ApexPages.StandardController(new product_inventory__c()); //create instance of standard controller
serpinv srv= new serpinv (controller); // Create instance of controller class
srv.saveChanges(); // call the method
}
Hi Pradeep,
Thank you for your reply!
I tried the following test code:
static testMethod void myTest()
{
product2 po=new product2(name='test');
product_inventory__c controller=new product_inventory__c(product__c=po.id);
serpinv srv = new serpinv(new ApexPages.StandardController(controller));
srv.saveChanges();
}
The call to save changes is throwing an error when i try to run the tests:
DmlException: Update failed. First exception on row 0; first error: MISSING_ARGUMENT, Id not specified in an update call: []
for the first line in the save changes method:
update this.po;
I tried removing the line -srv.saveChanges();
but this doesnt help for my code coverage percentage.
Please help
