And mighty hunger for I know not what.

As such an alternative has not been proposed to date, we conclude that the interpretation of atom interferometers as testing the gravitational redshift at the Compton frequency is unsound.
Does an atom interferometer test the gravitational redshift at the Compton frequency ?
In the present paper we analyze this claim in the frame of general relativity and of different alternative theories, and conclude that the interpretation of atom interferometers as testing the gravitational redshift at the Compton frequency is unsound.

As a consequence, they are in a good position to detect new errors, and also to improve the accuracy of the inferred contracts by discovering those that are unsound.
Stateful Testing: Finding More Errors in Code and Contracts
Since the inference is based on a finite number of observations and on heuristics in the form of templates, some of the inferred contracts can be unsound: they merely are a reflection of the test cases that have been exercised.
Stateful Testing: Finding More Errors in Code and Contracts
Unsound preconditions The first example shows how stateful testing can generate tests with a better coverage and detect unsound preconditions.
Stateful Testing: Finding More Errors in Code and Contracts
Unsound postconditions The second example shows how stateful testing can detect unsound dynamically inferred postconditions.
Stateful Testing: Finding More Errors in Code and Contracts
If tnew is passing, then the precondition p is unsound and removed from pre(r); if tnew is failing, a fault is found (and p is also unsound).
Stateful Testing: Finding More Errors in Code and Contracts
Detecting unsound postconditions: Inferred postconditions can be unsound, too, but we cannot directly select objects that violate postconditions, because we do not have direct control over post-states.
Stateful Testing: Finding More Errors in Code and Contracts
If tnew is valid and passing (with respect to r’s programmer-written contracts only) but C is false after executing it, the postcondition q is unsound and is removed from post(r); if tnew is failing (again with respect to r’s programmer-written contracts, which are always assumed correct), it also shows a fault.
