The paper considers the problem of testing control quality for a cosmonaut lifesaving device (CLD). The precision of CLD docking to the orbital station is assessed using a maximin testing scheme, including three stages. The first stage forms a testing strategy as a solution of a game theory problem. The second stage consists precisely in testing the control algorithm. This stage uses the system perturbations determined on the first stage and real control quality figures are computed. The third stage forms an assessement of the control algorithm.
