c# - Why do I get an ExpectationViolationException when using a Stub? -

this test using nunit 2.5 , rhino.mocks 3.5:

[testfixture] public class excelworksheetcolumntests {         private const string _name = "f1";         private const int _index = 0;          private mockrepository _repo;           [setup]         public void setup(){_repo = new mockrepository();}           private excelworksheetcolumn createcolumnusingfixturefieldsbutwith(iexcelworksheet excelworksheet)         {             return new excelworksheetcolumn(_name, _index, excelworksheet);         }          [test]         public void when_selectedshootcolumntype_is_changed_raises_selectedshootcolumntypechanged_event()         {             var stubworksheet = _repo.stub<iexcelworksheet>();              excelworksheetcolumn column =                 createcolumnusingfixturefieldsbutwith(stubworksheet);              stubworksheet                .stub(p => p.getselectedshootcolumntype(column))                .return(shootcolumntype.generic);              _repo.replayall();              bool ithappened = false;              column.selectedshootcolumntypechanged                  += (s, e) => { ithappened = true; };              column.selectedshootcolumntype = shootcolumntype.subjectid;              assert.that(ithappened);         }          [teardown]         public void teardown()         {             _repo.replayall();             _repo.verifyall();         } } 

fails message:

rhino.mocks.exceptions.expectationviolationexception : iexcelworksheet.setselectedshootcolumntype( classphotolink.model.createsubjectlist.excelworksheetcolumn, subjectid);

expected #0, actual #1.

i thought stubs returning values or ignoring method calls. why trying verify call to

iexcelworksheet.setselectedshootcolumntype(     iexcelworksheetcolumn column,      shootcolumntype type) 

?

in rhino mocks wiki says regards stub extension method "remember default rhino mocks ignore unexpected methods calls."

edits of test.

removing setup & teardown code, still fails:

    [test]     public void when_selectedshootcolumntype_is_changed_raises_selectedshootcolumntypechanged_event()     {         var repo = new mockrepository();         var stubworksheet = repo.stub<iexcelworksheet>();          excelworksheetcolumn column = createcolumnusingfixturefieldsbutwith(stubworksheet);          stubworksheet             .stub(p => p.getselectedshootcolumntype(column))             .return(shootcolumntype.generic);          repo.replayall();          bool ithappened = false;          column.selectedshootcolumntypechanged += (s, e) => { ithappened = true; };          column.selectedshootcolumntype = shootcolumntype.subjectid;          assert.that(ithappened);     } 

but works hoped.

    [test]     public void when_selectedshootcolumntype_is_changed_raises_selectedshootcolumntypechanged_event()     {         var stubworksheet = mockrepository.generatestub<iexcelworksheet>();          excelworksheetcolumn column = createcolumnusingfixturefieldsbutwith(stubworksheet);          stubworksheet             .stub(p => p.getselectedshootcolumntype(column))             .return(shootcolumntype.generic);          bool ithappened = false;          column.selectedshootcolumntypechanged += (s, e) => { ithappened = true; };          column.selectedshootcolumntype = shootcolumntype.subjectid;          assert.that(ithappened);     } 

so seems have repo.stub() versus mockrepository.generatestub();

using stub() means do expect method call. unexpected calls calls methods on no expectation has been set.

update

i'm wondering if problem use of setup, teardown, , record/replay, unnecessary.

what happens if write test way:

[testfixture] public class excelworksheetcolumntests {         private const string _name = "f1";         private const int _index = 0;          private excelworksheetcolumn createcolumnusingfixturefieldsbutwith(iexcelworksheet excelworksheet)         {             return new excelworksheetcolumn(_name, _index, excelworksheet);         }          [test]         public void when_selectedshootcolumntype_is_changed_raises_selectedshootcolumntypechanged_event()         {             var stubworksheet = mockrepository.stub<iexcelworksheet>();              excelworksheetcolumn column =                 createcolumnusingfixturefieldsbutwith(stubworksheet);              stubworksheet                .stub(p => p.getselectedshootcolumntype(column))                .return(shootcolumntype.generic);              bool ithappened = false;              column.selectedshootcolumntypechanged                  += (s, e) => { ithappened = true; };              column.selectedshootcolumntype = shootcolumntype.subjectid;              assert.that(ithappened);         } }
