Can you help me with this test class.

Issue1: Method does not exist or incorrect signature: void getOpportunity(Id) from the type classController

Issue2: Method does not exist or incorrect signature: void createTask(Id, String, String, String, Date, Id) from the type classController

The errors are very simple (and remarkably clear, at least for Salesforce).

A method signature consists of:

  • The return type
  • The name of the method
  • The number of arguments the method expects, along with their types, in order (left to right)

So the signature for your getOpportunity() method is Opportunity getOpportunity(String, String)

  • Return type = Opportunity
  • Method name = getOpportunity
  • 2 arguments of type String

In your test class, you're only passing a single string to getOpportunity(). Since getOpportunity()'s signature dictates that you pass it 2 strings, passing only one results in an error. All method arguments are required, you can't just leave out data. At the very least, you'll need to pass null (or an empty string) in for the second argument.

For your second error, you are both missing an argument (the method you're calling requires 7, your test is trying to call it with 6) and your arguments are not in the correct order. In your controller class, you defined the order to be createTask(Id, String, Id, String, String, String, Date){. You must stick to that exact order when calling createTask().

  • Thanks a lot!!!
