Website applications surpass system-based applications because they are nature friendly and installation free. Additionally, model-based testing is more beneficial under website applications as it saves time and money. Moreover, it detects fault lines at a higher speed. With the commencement of web application testing and model-based testing, various tools and models have been introduced in the domain of web application. In this milieu, systematical identification got significant importance to analyze MBT. To analyze the MBT, articles published between the years 2000 to 2022 are collected. From the total of 6115 papers are analyzed and 43 papers are selected. The presented SLR of MBT for the web application presents a comprehensive review of all the models and tools proposed in the literature. Furthermore, the taxonomy is defined about the models and steps followed in MBT. Lastly, the challenges and gaps are addressed. Hence, it is also helpful for researchers to avert the obstacles in the field of MBT for website applications.
