Tests for metadata in Level 3 products

[stscijgbot-rstdms]

Issue RCAL-671 was created on JIRA by Nadia Dencheva:

The ResampleStep will create a mosaic L3 file containing an attribute named {}resample{}, which will hold metadata relevant to the resampling step in creating the mosaic. The metadata are:

• {}pixel_scale_ratio{};
• {}pixfrac{};
• {}pointings{};
• {}product_exposure_time{};
• {}weight_type{};
• {}members{}.
  The test is successful when meta.resample attribute is present and contains all of the keywords in the list above.

 
|Success Criteria:|The meta.resample attribute is present and contains all required keywords.|
|Expected Artifacts:|Mosaic L3 file in ASDF format.|
|Brief Outline of Test Steps:|The ResampleStep is run on a series of L2-calibrated input files, resulting in a mosaic L3 file. The test will take the L3 file and check if the meta.resample attribute is present as well as if it contains all of the required parameters.|
|Inputs:|L2 input files to be combined into a mosaic.|
|Test Methods:|Demo|
|Outputs:|Mosaic L3 file is ASDF format.|
