@luotao1 Can you give some advice. I'm not very good at it.

There is one TODO for the cmake that I haven't fixed:
I haven't make the test depending on test_word2vec and test_image_classification yet.

@wanglei828 CI is failing for this PR

[luotao1]

Paddle/paddle/fluid/inference/tests/book/CMakeLists.txt

Lines 22 to 23 in e00c1ee

	set_tests_properties(test_inference_${TARGET_NAME}${arg}
	PROPERTIES DEPENDS test_${TARGET_NAME})

python单测的名字是test_xxx，而inference_test_ARGS的名字是api_impl，没对上导致依赖没生效。

所以仿照paddle/fluid/inference/tests/book/CMakeLists.txt再来改一下就可以了。

@luotao1 I think you may not understand this correctly. In the file, I call the function like this:
inference_api_test(api_impl
ARGS test_word2vec test_image_classification)
after parsing,
the variable "inference_test_ARGS" should be "test_word2vec; test_image_classification" which is correct.
when I use:
set_tests_properties(test_paddle_inference_${TARGET_NAME}
PROPERTIES DEPENDS "${inference_test_ARGS}")
it will be interpreted as this:
set_tests_properties(test_paddle_inference_api_impl PROPERTIES DEPENDS "test_word2vec; test_image_classification" )

You can read this reference: https://cmake.org/cmake/help/v3.0/module/CMakeParseArguments.html

Got it.

@panyx0718 I fixed the CI fail. It is mainly because the test cases are not put in the "WITH_TESTING" control flow.

[luotao1]

LGTM!

[luotao1]

cc_test里面会判断if(WITH_TESTING)，这里不需要加了。

[luotao1]

Got it.

Thanks!
