我正在使用Google測試和Google Mock來處理我的C++/Qt應用程序。我一直有這個設置了巨大的成功,直到剛纔,當我嘗試這樣做:Google Mock在嘗試指定返回值時給出編譯錯誤

QList<AbstractSurface::VertexRow> rowList; 
for (unsigned i = 0; i < rows; ++i) 
{ 
    AbstractSurface::VertexRow curRow(new AbstractSurface::Vertex[cols]); 
    for (unsigned j = 0; j < cols; ++j) 
    { 
     curRow[j] = AbstractSurface::Vertex(); 
    } 
    rowList.append(curRow); 
} 
ON_CALL(surface, numRows_impl()).WillByDefault(Return(rows)); 
ON_CALL(surface, numColumns_impl()).WillByDefault(Return(cols)); 
ON_CALL(surface, popAllRows_impl()).WillOnce(Return(rowList)); 
/* ... */ 

試圖編譯這將導致以下錯誤消息從GCC:

../../3DWaveSurface/test/TestWaterfallPresenter.cc: In member function ‘virtual void<unnamed>::WaterfallPresenterTest_CallingPaintGLCallsPaintRowForEachRowInSurface_Test::TestBody()’: 
../../3DWaveSurface/test/TestWaterfallPresenter.cc:140:41: error: ‘class testing::internal::OnCallSpec<QList<boost::shared_array<AbstractSurface::Vertex> >()>’ has no member named ‘WillOnce’ 

如果有幫助,VertexRowtypedef,對於boost::shared_array<Vertex>Vertex是帶有有效的空構造函數的struct

這是我寫的測試錯誤還是與使用QListshared_array有些不兼容?


SOLUTION 以下VJo的建議後,我的測試編譯和運行,但隨後崩潰:

Stack trace: 
: Failure 
Uninteresting mock function call - returning default value. 
    Function call: popAllRows_impl() 
    The mock function has no default action set, and its return type has no default value set. 
The process "/home/corey/development/3DWaveSurface-build-desktop-debug/test/test" crashed. 

因爲沒有爲popAllRows_impl()沒有默認的回報。我加了默認:

ON_CALL(surface, popAllRows_impl()).WillByDefault(Return(QList<AbstractSurface::VertexRow>())); 

要我SetUp(),一切都很好。作爲VJo指出,沒有爲ON_CALL WillOnce()但對於EXPECT_CALL,我錯過了這個烹調手冊..

最簡單的解決方法是:

EXPECT_CALL(surface, popAllRows_impl()).WillOnce(Return(rowList)); 

編輯:

ON_CALLWillByDefault,但沒有WillOnce方法。檢查gmock cookbook

+0

這實際上工作(有一個額外的我做了我的設置)。將在原始問題中發佈完整解決方案。 –
