• The first comprehensive assessment of many extended finite state machine (EFSM) based test suites using typical types of EFSM faults.
• Considered types of faults include single transfer, double transfer, single output parameter, and single assignment faults.
• Eleven types of EFSM based test suites are considered in the assessment.
• Ranking of the test suites is carried out with respect to their fault coverage and length.
• Obtained results are summarized and dispersion of test suites coverage is provided.
