### Question:
GridCoverage extends org.apache.sis.coverage.grid.GridCoverage implements Localized { public RenderableImage getRenderableImage(final int xAxis, final int yAxis) { return new Renderable(xAxis, yAxis); } protected  GridCoverage(final CharSequence name,
                           final GridGeometry grid,
                           final List<? extends SampleDimension> bands); protected  GridCoverage(final CharSequence name, final GridCoverage coverage); protected  GridCoverage(final CharSequence name,
                           final GridGeometry grid,
                           final List<? extends SampleDimension> bands,
                           final GridCoverage[] sources); InternationalString getName(); Envelope getEnvelope(); @Override RenderedImage render(GridExtent sliceExtent); RenderableImage getRenderableImage(final int xAxis, final int yAxis); @Debug void show(String title, final int xAxis, final int yAxis); @Debug void show(final String title); @Debug void show(); @Override Locale getLocale(); @Override String toString(); boolean dispose(boolean force); List<org.apache.sis.coverage.grid.GridCoverage> getSources(); static final Logger LOGGER; }### Answer:
@Test public void testRandomCoverage() { createRandomCoverage(); assertRasterEquals(coverage, coverage); assertSame(coverage.getRenderedImage(), coverage.getRenderableImage(0,1).createDefaultRendering()); GridCoverage2D geophysics= coverage.view(ViewType.GEOPHYSICS); assertSame(coverage, coverage.view(ViewType.PACKED)); assertSame(coverage, geophysics.view(ViewType.PACKED)); assertSame(geophysics, geophysics.view(ViewType.GEOPHYSICS)); assertFalse( coverage.equals(geophysics)); assertFalse( coverage.getSampleDimensions().get(0).getTransferFunction().get().isIdentity()); assertTrue(geophysics.getSampleDimensions().get(0).getTransferFunction().get().isIdentity()); }
