Software quality assurance has been a heated topic for several decades, butrelatively few analyses were performed on open source software (OSS). As OSShas become very popular in our daily life, many researchers have been keen onthe quality practices in this area. Although quality management presentsdistinct patterns compared with those in closed-source software development,some widely used OSS products have been implemented. Therefore, qualityassurance of OSS projects has attracted increased research focuses. In thispaper, a survey is conducted to reveal the general quality practices in opensource communities. Exploratory analysis has been carried out to disclose thosequality related activities. The results are compared with those fromclosed-source environments and the distinguished features of the qualityassurance in OSS projects have been confirmed. Moreover, this study suggestspotential directions for OSS developers to follow.
