test function for sequencial data

[shuqi-mo]

Describe the bug

The sasrec's colab failed to run the test function after the training is finished. I reviewed the code of train_engine.py and found that the test function applies the EvalEngine in eval_engine.py. Perhaps the sequencial data should apply the SeqEvalEngine instead?

To Reproduce

Please provide a Minimal, Complete, and Verifiable example here. We hope we can simply copy/paste/run it. It is also nice to share a hosted runnable script (e.g. Google Colab), especially for hardware-related problems.

Describe your attempts

• I checked the documentation and found no answer
• I checked to make sure that this is not a duplicate issue

You should also provide code snippets you tried as a workaround, StackOverflow solution that you have walked through, or your best guess of the cause that you can't locate (e.g. cosmic radiation).

Context

• OS [e.g. Windows 10, macOS 10.14]:
• Hardware [e.g. CPU only, GTX 1080 Ti]:
• Environment [e.g. Pytorch 1.4, Tensorflow 2.0]:

In addition, figure out your used Beta-Recsys version. Then attach the corresponding label on the issue.
