Description

We recenty had failing integrationtests that computed ndwi/ndii/msi based on 20m bands, sometimes in combination with 10m. This was caused by a small change in resampling, the new results were better than before. We can probably construct a unit test that replicates the integrationtest, giving us an early warning when something happens to the sampling. (This is a quite sensitive area, and harder to debug when exposed by integrationtest.)

Contributor guide

Research direction
Find the existing integration tests that compute NDWI/NDII/MSI from 20m and 10m bands, and identify the resampling logic that was recently changed. Review the project's unit testing framework and existing test examples to understand how to write a focused unit test that replicates the integration scenario, so you can catch regressions early.
