Hi,

The param_scope() method doesn't work inside tests. Is it intentional? Here is the param_scope() method: https://github.com/PaddlePaddle/Paddle/blob/af15f6f0380a3975239d7d4a6c7c682f4058d309/paddle/fluid/framework/ir/fuse_pass_base.h#L35

This is troublesome because I can't write a test for my conv_bn_fuse_pass beacuse I use scope in it. This function works when run from a resnet50 pass test program. What should I do? I have noticed that other passes (like fc_gru) also use scope and they don't have tests.
