Tests that the matrix elements are independent of the screening parameter 'a' used in the Ewald summation. Notice that the real space cutoff a

Tests that an ASE Atoms is succesfully converted to a System object.

Tests the inner averaging (averaging done before calculating power spectrum).

Tests the outer averaging (averaging done after calculating power spectrum).

Test that the implementation of the gaussian value through the cumulative distribution function works as expected.

Tests that the cell list implementation returns identical results with the naive calculation.

Test that coordinates are correctly wrapped inside the cell.

Tests that the REMatch kernel correctly converges to the average kernel at the the limit of infinite alpha.

Tests different valid and invalid create values.

Tests that disabling/enabling crossover works as expected.

Tests that the similarity is correct.

Tests that the periodicity is taken into account when calculating distances.

Tests that the results are consistent with the electrostatic interpretation. Each matrix [i, j] element should correspond to the Coulomb energ

Walks through the examples folder and tests each example by dynamically importing them which will also run their code.

Tests different invalid parameters that should raise an exception.
