1. A method for indicating significance of tested code statements, the method comprising: a processor receiving a rule containing a first set of code statements; the processor comparing the first set of code statements of the rule to a second set of code statements of a plurality of code statements of a source code; in response to the first set of code statements of the rule matching the second set of code statements of the plurality of code statements of the source code, the processor applying a weight modifier to the rule, wherein applying the weight modifier to the rule adds a weighted value to the rule; and the processor, in response to a second matching of the first set of code statements of the rule to the second set of code statements of the plurality of code statements of the source code, applying the weight modifier to the rule, wherein the rule includes a weighted value and the weight modifier adjusts the weighted value of the rule.
