Test Case Descriptions

2015-09-29

We consider the mult-size products specification as successfully implemented if the test cases described in this page are performed successfully.

 

Create text fixtures from following variations:

  • GeoCoding type: CrsGeoCoding, TiePoint/PixelGeoCoding

  • Single GeoCoding per product and multiple per band

  • All bands same size and bands with different sizes

  • Use masks derived from existing bands (and masks)

  • Use bands with and w/o no-data values, valid-pixel expressions

  • Same size but different spatial resolution (optional)

  • Spatial extents of two or more bands are congruent, non-congruent or even non-overlapping (optional)

  • Computation by an operator via computeTile and computeTileStack

Various test cases shall assert that

  • each product variation has an expected model CRS

  • image pixel positions are correctly transformed into model coordinates and vice versa for various bands

  • simple raster data ops lead to expected results when applied to product variations: subset (mandatory), reprojection (mandatory), band maths (optional), statistics (optional)

  • pixel data extraction as used in spectrum view for various bands in various products

  • all bands with same raster size have the same image layout (= same image pyramid models with same tile sizes)

  • the valid-mask of bands (if any) has the same image layout (= same image pyramid models with same tile sizes) as the band
