Major Revisions

From the comments of the reviewers, the paper has some importance and contribution. However, there are some disadvantages, especially for presentions. The authors should improve the paper according to the comments of the reviewers.

[# PeerJ Staff Note: Please ensure that all review comments are addressed in a rebuttal letter and any edits or clarifications mentioned in the letter are also inserted into the revised manuscript where appropriate.  It is a common mistake to address reviewer questions in the rebuttal letter but not in the revised manuscript. If a reviewer raised a question then your readers will probably have the same question so you should ensure that the manuscript can stand alone without the rebuttal letter.  Directions on how to prepare a rebuttal letter can be found at: #]

[# PeerJ Staff Note: The review process has identified that the English language must be improved. PeerJ can provide language editing services - please contact us at for pricing (be sure to provide your manuscript number and title) #]

Reviewer 1 ·

Basic reporting

The English in the paper has to be improved substantially, as it is very difficult to understand and follow the arguments included in the paper. Table 7, for example, is not in English but Turkish.

Sufficient background information and references have been provided but again due to the bad use of the language it is not very easy to follow them.

The structure needs to be revised as well, just Table 7 shows the deficiency in that respect.

The paper is self contained and relevant results to the hypothesis have been obtained. But the presentation of the results (e.g. Figure 3) is not very clear.

Otherwise the paper is written in accordance with formal rules.

Experimental design

The paper proposes a mutant selection method using different criteria derived from social network analysis. Mutants are artificially introduced faults used to test the efficiency of tests developed for Finite state machines. It is important to generate include these into systems efficiently in order to measure the performance of the test sets.

The question adequately designed and and has some importance and contribution, but in my opinion it is not a very significant one.

The author has performed rigorous analysis, and results reflect these although not very well presented.

These results would be useful for future researchers who may want to compare their results with others.

Validity of the findings

As stated before there is some novelty in the findings but the impact may be questioned.

The author presented the study in detail but again these are veiled due to language usageç

The conclusion may be improved, but contents are appropriate for the findings.
