I am trying to write a test class for for the class below, which I had deployed to our production before, I made some little modifications ot the class to query a list of related items and put them into a select option list for a Picklist field on a VF page.  I thought it was a small change but it seems to have completely messed up my test class and I am not sure why.  I get the error: System.QueryException: List has no rows for assignment to SObject.  I'd  appreciate any assistance.

    public List<SelectOption> woList {get;set;}
    public RiskEditPage(apexPages.StandardController controller){
