trainer/tests/CMakeLists.txt and gserver/tests/CMakeLists.txt can be simplified with some common cmake function. For example,

################# test_Compare ############################
add_unittest_without_exec(test_Compare
    test_Compare.cpp)
add_test(NAME test_Compare
  COMMAND ${PADDLE_SOURCE_DIR}/paddle/.set_python_path.sh -d ${PADDLE_SOURCE_DIR}/python
        ${CMAKE_CURRENT_BINARY_DIR}/test_Compare
    WORKING_DIRECTORY ${PADDLE_SOURCE_DIR}/paddle/)

################# test_Trainer ###########################
add_unittest_without_exec(test_Trainer
    test_Trainer.cpp)
add_test(NAME test_Trainer
  COMMAND ${PADDLE_SOURCE_DIR}/paddle/.set_python_path.sh -d ${PADDLE_SOURCE_DIR}/python/
        ${PADDLE_SOURCE_DIR}/paddle/.set_python_path.sh -d ${PADDLE_SOURCE_DIR}/python/
        ${CMAKE_CURRENT_BINARY_DIR}/test_Trainer
    WORKING_DIRECTORY ${PADDLE_SOURCE_DIR}/paddle/)

Can be simplied as :

set(PYTHON_PATH 
   ${PADDLE_SOURCE_DIR}/paddle/.set_python_path.sh -d 
   ${PADDLE_SOURCE_DIR}/python/:${PADDLE_SOURCE_DIR}/paddle/trainer/tests)
function(trainer_test TARGET)
  add_unittest_without_exec(${TARGET} ${TARGET}.cpp)
  add_test(NAME ${TARGET}
    COMMAND ${PYTHON_PATH} ${CMAKE_CURRENT_BINARY_DIR}/${TARGET}
      WORKING_DIRECTORY ${PADDLE_SOURCE_DIR}/paddle/)
endfunction()

trainer_test(test_Compare)
trainer_test(test_Trainer)
