Unit Tests

One test file per exported function (test-wri_overview.R, test-layer_info.R, test-get_layer.R).

For each function, test at least:

• Success: valid inputs return the expected output type and structure
• Input validation: invalid inputs (wrong bbox length, out-of-extent, non-numeric) throw informative errors
• Edge cases: bbox at dataset edge, requesting a layer that exists but isn't hosted yet
• Return structure: for get_layer, confirm output is a SpatRaster, has correct CRS (EPSG:5070), and extent matches input bbox

General:

• One test_that() block per behavior
• All tests pass check() without warnings or notes
