Description of proposed changes

This PR refactors the pygmt.grdgradient tests to use xarray.testing.assert_allclose() rather than pygmt.grdinfo() in preparation for the deprecation associated with better return values for grdinfo (#593).

Fixes #

Reminders

  • Run make format and make check to make sure the code follows the style guide.
  • Add tests for new features or tests that would have caught the bug that you're fixing.
  • Add new public functions/methods/classes to doc/api/index.rst.
  • Write detailed docstrings for all functions/methods.
  • If wrapping a new module, open a 'Wrap new GMT module' issue and submit reasonably-sized PRs.
  • If adding new functionality, add an example to docstrings or tutorials.

Slash Commands

You can write slash commands (/command) in the first line of a comment to perform
specific operations. Supported slash commands are:

  • /format: automatically format and lint the code
  • /test-gmt-dev: run full tests on the latest GMT development version

Just a quick note for while you're updating the open PRs that you could use an even smaller subregion from @static_earth_relief to make the fixture_grid_result contents simpler.

npt.assert_allclose(temp_grid.max(), 0.0575332976)
npt.assert_allclose(temp_grid.median(), 0.0004889865522272885)
npt.assert_allclose(temp_grid.mean(), 0.0028633063193410635)
result = grdgradient(grid=grid, azimuth=10, direction="c")

In future GMT releases, azimuth and direction will not be allowed together because the two options are contradictory (see discussion in GenericMappingTools/gmt#6327). Sorry for the extra work, but I recommend updating this test to use only one of these two parameters.

Good idea!
