Coverage in EPL Espertech mutant operators

A complete Esper EPL mutation operator classification can be found in Gutiérrez-Madroñal [1] thesis. There are 34 mutation operators across four categories, depending on the type of element they are related to. The coverage instrumentation can be applied to the 22 Esper EPL mutation operators in the replacement operators category, out of which RSC was discarded as well as it only replaces a keyword in the select clause (and the select clause is always run). So, there are 21 mutation operators in the replacement operator category in which coverage instrumentation could be added.
