37 * Tests for energy output to log and .edr files.
39 * \todo Position and orientation restraints tests.
40 * \todo Average and sum in edr file test.
41 * \todo AWH output tests.
42 * \todo The log and edr outputs are currently saved to the file on the disk and then read
43 * to compare with the reference data. This will be more elegant (and run faster) when we
44 * refactor the output routines to write to a stream interface, which can already be handled
45 * in-memory when running tests.
