Non-Intrusive voice Quality Analyzer
NIQA
The most known methods for quality evaluation of voice transmission systems were developed by Telecommunication Standardization Sector of International Telecommunications Union (ITU-T) in the middle of 90-s. Results of this work are presented in Recommendation P.800 (P.830) «Methods for subjective determination of transmission quality» [1, 2]. This document describes conditions for voice quality testing, audio contents, scoring and methods to evaluate results. Typically “Methods for subjective determination of transmission quality” are used to obtain mean subjective quality score according to five-digit scale (Mean Opinion Score – MOS).

Exploratory Test Code Coverage
Exploratory testing is simultaneous learning, test design, and test execution of critical areas in the application. It is an efficient method to provide rapid feedback and uncover critical bugs in newly released features. As these tests are manual and their execution duration is longer and more expensive, it’s important to minimize overlap with other test types. Gain visibility into which code areas are being tested with manual and exploratory tests to improve team efficiency and speed.
