  Characterization of quantum devices received from unknown providers is a
significant primary task for any quantum information processing protocol.
Self-testing protocols are designed for this purpose of certifying quantum
components from the observed statistics under a set of minimal assumptions.
Here we propose a self-testing protocol for certifying binary Pauli
measurements employing the violation of a Leggett-Garg inequality. The scenario
based on temporal correlations does not require entanglement, a costly and
fragile resource. Moreover, unlike previously proposed self-testing protocols
in the prepare and measure scenario, our approach requires neither dimensional
restrictions, nor other stringent assumptions on the type of measurements. We
further analyse the robustness of this hitherto unexplored domain of
self-testing of measurements.
