We consider the one-sided testing for the shape parameter in the half exponential power distribution. Under the noninformative priors such as the reference priors, we develop the objective Bayesian testing methods for the shape parameters. Since the noninformative priors is improper, the Bayes factors can not be computed accurately. Thus we want to develop the Bayesian testing methods via the fractional Bayes factor and the intrinsic Bayes factors to solve this problem. To evaluate the performance of the proposed Bayesian testing methods, we compute the posterior probabilities in some environments of parameters and sample sizes. Thus numerical studies and an example are provided.
