The owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all rights whatsoever. All rights to such intellectual property are fully reserved by the owner. FIELD OF INVENTION [0002] The present disclosure generally relates to the field of telecommunications. More particularly, the present disclosure relates to a system and a method to perform automated testing on new cells. BACKGROUND OF THE INVENTION [0003] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admission of the prior art. [0004] Conventional manual verification methods for network elements, including macro cells, small cells, and bi-sector antennas, the process involves extensive manual intervention and verification. This approach requires network engineers and technicians to manually configure and test each individual network element, ensuring its proper functioning and adherence to predefined parameters. These manual verification methods of network elements are a time-intensive process. Each element requires individual attention and configuration, leading to delays in network deployment and optimization. The need for manual intervention at every step significantly slows down the overall verification process. Also, manual verification methods heavily rely on human operators, making it susceptible to human error. Mistakes in configuration, parameter settings, or data analysis can lead to inaccuracies and compromised network performance. The complexity of network configurations increases the likelihood of errors during the manual verification process. These methods lack consistency across different network elements. As each element is verified individually by different operators, there is a risk of inconsistent approaches, resulting in variations in performance and configuration. This inconsistency can impact overall network efficiency and reliability. [0005] Further, these methods become increasingly challenging and resource-intensive as the network expands. With the proliferation of network elements, the number of configurations and tests required grows exponentially, and network engineers and technicians spend substantial time and effort on repetitive tasks, leading to increased operational costs. The need for skilled personnel to perform manual verification further adds to the overall expenses. [0006] There is, therefore, a need in the art to provide a system and a method that can mitigate the problems associated with the prior arts. DEFINITION [0007] As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used to indicate otherwise. [0008] The term RET as used herein, refers to remote electrical tilt. The RET allows to adjust the electrical tilt of an antenna remotely. The RET is mainly used for mobile radio antennas, for example to optimise the alignment of the mobile radio network at hotspots like events. [0009] The term RRC as used herein, refers to radio resource control protocol. The RRC protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between a user equipment (UE) and a base station. [0010] The term CQI as used herein, refers to channel quality indicator, the CQI is a key parameter in communication system design that encodes the state of the channel. With this information, a base station can adjust the quality of service that would best suit the channel at that time and place, thereby facilitating communications. OBJECTS OF THE INVENTION [0011] It is an object of the present disclosure to provide a system and a method that enables in-depth analysis of Performance Management Key Performance Indicators (PM KPIs) and optimization of Remote Electrical Tilt (RET), and this integration enhances the system's ability to identify and address discrepancies, leading to improved network performance. [0012] It is an object of the present disclosure to provide a system and a method that utilizes advanced techniques to examine PM KPIs, allowing for a s
