a unified Data test

[floatingCatty]

Background

In case we add multiple DFT output dependence. A unified test of data parsing and dataset building is essential. The test can be divided into two steps:

1. The parsing test of each DFT package's interfaces.
2. The unified test of data set building from parsing results.

Describe the solution you'd like

Implement the function to support this test.
