I have been trying to write test class for 100% coverage. I have difficulty in understanding how to call the standard controller and call the parameterised constructor also set the page to the current page as the current page. On the account view page, I have overridden the new button on the related list of a custom object. I am able the use the same class when I edit the record. On both the edit record view page and the new record view page I am able to retrieve the account id. Currently I am able achieve 65% coverage. I am not sure what am I doing wrong. Please help if possible. I have attached the code below.
Thanks Gayatri
//my Class
public class NewTaxExempt{
public TaxExempt__c obj {get; set;}
public String selectedIso {get;set;}
public List<selectOption> isoCodes {
get {

for (State__c iso : State__c.getAll().values())
options.add(new SelectOption(iso.State_ISO__c,iso.State_Name__c+' - '+iso.State_ISO__c));
return options;
}
set;
}
// onload standard controller will be called.
public NewTaxExempt(ApexPages.StandardController controller) {

it's gonna be much easier if you knew what part of your code is missing in test coverage.
uncovered part will be in red. now try to write tests for them.
If you want to cover your class properties all you have to do is this:
@isTest static void myPropertiesTest(){
MyClass obj = new MyClass();
obj.myProperty = SomeValue;
// now assert a function in you class that uses this property.
// an easy and dumb way is to just assert the property.
System.assertEquals(SomeValue, obj.myProperty);
}
