Tests can be found under /exec/tests subdir.
RFD (/tests/RFDanalysis):
Run with rfd_tog on and off, analyse particle distribution using Mathematica file. PASSED.

periodic electrostatic (/tests/electroPeriodic):
Run using input file and results for various particle positions will print out

• force between two particles across x boundary between two boxes, within p3m range: PASSED
• force between two particles across x boundary in same box, within p3m range: PASSED
• force between two particles in opposite periodic corners, within p3m range: MAYBE, ~6% error?
• force between two particles across x boundary between two boxes, outside p3m range: PASSED, ~2.3% error

electrostatic with zero potential walls on y boundaries (/tests/electroTwoWall):
Run using input file and results for various particle positions will print out

-force between two particles across x boundary between two boxes, outside p3m range: MAYBE, 4% error.
-force between two particles across x boundary between two boxes, within p3m range of each other, marginally outside p3m range of wall: MAYBE, 5.1% error in component pointing to wall.
-force between two particles across x boundary between two boxes, within p3m range of each other, further outside p3m range of wall: PASSED, 2.4% error in component pointing to wall.
-force between two particles across x boundary between two boxes, within p3m range of each other and wall, but not with partner's image charge: PASSED, 2.4% error.
-force between two particles across x boundary between two boxes, within p3m range of each other and wall, including partner's image charge: PASSED, 2.4% error.
-force between two particles across periodic, within p3m range of each other and wall, including partner's image charge: PASSED, 2.4% error.
-force between two particles across periodic, within p3m range of each other and wall, but not with partner's image charge: PASSED, 1.6% error.

force spreading with slip and no slip y boundaries (/tests/boundarySpreading):
Run using slip and no slip input files, total force in valid regions is printed out and compared to expected result.

-force spread in free space - PASSED
-force spread in center of box face near y=0 wall - PASSED
-force spread on box edge near y=0 wall, z=0 periodic - PASSED
-force spread on box corner near y=0 wall, z=0 periodic, and x=dom/2 box interface - PASSED
