"WebHigher-order mutants are enabled by creating mutants with more than one mutation. Mutation testing is done by selecting a set of mutation operators and then applying them to the source program one at a time for each applicable piece of the source code. The result of applying one mutation operator to the program is called a mutant. " - Higher-order mutants
