Another common way of naming statistical tests is according to the distribution against which they are tested - most notably, for a variety of tests, the chi-squared distribution. (Confusingly, the t-test compares the t-statistic with the t-distribution.)

Other tests are named after their originators. As a result, some tests are known by several names, and a plethora of very similar tests have been devised - assuring the authors' immortality.

For his part, Fisher was a great developer of statistics and tests - with the inevitable result. Blithely unaware of this fact, a remarkable number of workers happily state they have subjected their results to an (otherwise unspecified) 'chi-squared test' or 'Fisher's test'.
