A test that assumes symmetry would not quite qualify as nonparametric in this setting. On a slightly related matter empirical likelihood and bootstrap do not work well for means with highly skewed distributions. | |

There are nonparametric tests for means. For instance, consider the family of all symmetric distributions of finite mean and apply any nonparametric test of medians (which coincide with their means). Although "symmetric" is the kind of strong condition we feel is needed to test means, it's still nonparametric. | |
