Shiv Shankar How to get test coverage for catch part
Hello friends,
i have following class with test method i want to know how can i get test coverage for catch part.
public Class AutoCompleteController{
public String[] jsonDescriptionData;
public AutoCompleteController(BrowseCatalog controller) {
}
public AutoCompleteController(){
}
public List<string> getjsonDescriptionData(){
try{
if(jsonDescriptionData == null){
jsonDescriptionData = new List<string>();
}
else{
jsonDescriptionData.clear();
}
List<Product__c> productDesList = [select id, Name, Default_Sales_Description__c from product__c];
if(productDesList != null && productDesList.size() != 0){
Set<String > temp = new Set<String>();
for(product__c rec : productDesList ){
temp.add(rec.Default_Sales_Description__c);
temp.add(rec.Name);
}
for(String rec : temp){
jsonDescriptionData.add('"'+rec+'"');
}
}
return jsonDescriptionData;
}catch(Exception e){
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.WARNING,e.getMessage()));
return null;
}
}
public static testMethod void testAutoCompleteController(){
List<Product__c> proList = new List<Product__c>();
Product__c pro1 = new Product__c(Name='111', Active__c=true, Alcohol__c=10, Allergen_OK__c='Yes', CAN_TTB_Approved__c='yes', Default_Sales_Description__c = 'Lemon Tea');
Product__c pro2 = new Product__c(Name='112', Active__c=true, Alcohol__c=10, Allergen_OK__c='Yes', CAN_TTB_Approved__c='yes', Default_Sales_Description__c = 'Lemon Tea');
proList.add(pro1);
proList.add(pro2);
insert proList;
AutoCompleteController controller = new AutoCompleteController();
controller.getjsonDescriptionData();
controller.getjsonDescriptionData();
BrowseCatalog brocat = new BrowseCatalog();
AutoCompleteController controller1 = new AutoCompleteController(brocat);
}
}
I would make a boolean like "Boolean throwerror = false" and set it to true the second time you call it with your test class.
try{if(throwError) {
throw new MyCustomException(myMessage, ex);
} if(jsonDescriptionData == null){ jsonDescriptionData = new List<string>();
.........................
Then assert that the error was thrown with something like this:
ThrowError = true;Try {
controller.getjsonDescriptionData();
} catch (exception e) {
system.assert(e.getMessage().contains('your error message'), e.getMessage());
}
Hope this helps!
