COMPARATIVE ANALYSIS OF COMPLEX INFORMATION SYSTEM TESTING METHODS

The research has been based on surgical experience of multiple decades and on retrospect study of more that 4000 clinical cases, among them 3500 surgical invasion due to different types of traumas. Since it relies on the latter, it shows the evolution of our approaches towards severe cerebral cranial traumon includes different matters regarding diagnostics and surgical treatment with neuropathogenetic approach. We have shown the advantages of certain surgical procedures in cases of cerebral cranial trauma and also the way approaches were changing after introduction of high medical technology and taking into consideration bio mechanisms and pathological data. Computer diagnostics changed several surgical procedures and opportunities. In cases of traumas impacted in immobilized condition method of choice used to be plastic craniotomy, when in cases of cerebral congestion would cause decompression, placing bone fragment under the skin. 902 surgeries were performed among 1990. In 894 cases surgeries were performed using plastic trepanation, 217 among them was performed with improved modified method. In cases of negligible brain congestion, bone fragment was left in its place without suture fixation and after the congestion resolution fragment would return to its anatomical location. In several times it would be ligated in 2-3 points. This method was the most efficient in bi-frontal low craniotomy. The need of removing bone fragment was observed in zero cases.

Introduction.
With the increasing complexity of modern information systems, ensuring their quality, reliability, and performance is of paramount importance.This study conducts a comparative analysis of complex testing methods to illuminate the challenges they present and provide insights into best practices for their application [1].
The study encompasses an in-depth analysis of five complex testing methods, each tailored to specific tasks and objectives.These methods include Performance Testing, Security Testing, Test Automation, Usability Testing, and Accessibility Testing.As organizations grapple with diverse quality control challenges, the choice of testing methods becomes a critical decision to ensure that the unique demands of each situation are met [2][3][4].
Selecting and implementing testing methods for specific contexts can be a daunting undertaking for organizations.Inadequate testing can result in undetected defects, exposing systems to security, performance, and functional vulnerabilities.Conversely, overly rigorous quality control can strain an organization's resources, budget, and timeline, potentially causing delays in system implementation.Therefore, the selection of testing methods must thoughtfully consider the distinctive challenges of the products and systems being tested.
Optimizing quality control is instrumental in achieving the efficient operation of information systems.A comprehensive understanding of complex testing methods, along with the ability to discern the issues each method can address, is indispensable.By tailoring testing approaches to suit the unique challenges of the products and systems at hand, organizations can strike a balance between quality control and efficient system development.

Materials and Methods.
An Ishikawa diagram was employed to identify potential causes of a quality characteristic.This diagram is structured around six primary categories: resources, processes, environment, personnel, management, and requirements.Each category was further subdivided into more specific potential factors that could influence software quality [5][6][7].
The Ishikawa diagram played a crucial role in pinpointing the principal challenges.Subsequently, it became essential to investigate specific testing methods and types in the context of these challenges.Given the multitude of testing methods available, it was imperative to determine which methods are considered complex within the technological landscape.To achieve this, a small-scale quantitative study was conducted, and the Pareto principle was applied to select the methods.A total of 65 specialists in the field participated in the survey [8].

Results.
Seventy-five professionals who received a questionnaire link through the social platform LinkedIn and email actively participated in the structured interviews.Geographically, the distribution of participants was diverse, ensuring a comprehensive perspective and enhancing the study's validity.
The participants represented various roles within organizations, including Quality Assurance (QA), management, development, operations, and other categories.This broad distribution provided a holistic view of the software testing landscape, encompassing the viewpoints of those directly involved in testing, process managers, and individuals influencing quality through different avenues.
Responses regarding the adequacy of experienced testers and the clarity of communication within teams shed light on essential aspects of team dynamics and resource allocation.These findings are pivotal for comprehending the current testing methods' effectiveness an d identifying potential areas for enhancement.
Insights into test environment stability and tester proficiency offered a deeper understanding of both technical and human factors.These responses contributed to a more comprehensive picture of the infrastructure supporting the testing process and the skills and experience of the individuals executing it.
The frequency of various testing types, such as performance and usability testing, indicated how often these complex methods were employed.Differences in testing frequency could be attributed to various factors, including project nature, resource availability, or specific client requirements.
Evaluations of the current security testing methods' effectiveness and the implementation and impact of automated testing provided valuable insights.Understanding the perceived effectiveness of these methods highlighted areas of operational efficiency and areas requiring improvement.
Responses concerning testing duration and the prioritization of testing tasks offered valuable insights into the challenges faced by testers in real-world scenarios.
The challenges reported in real-time monitoring of implementation results offered a deeper understanding of potential issues that might arise during this critical phase.These insights can inform strategies to mitigate such issues in future projects.
It is noteworthy that clear trends are emerging in the field of testing, focusing on efficiency in security testing methods, the adoption of automated testing, the establishment of stable test environments, addressing limitations in testing (such as time and resources), and improving the documentation of test cases.These trends align with the Pareto principle, emphasizing the significance of these five key areas for improvement.Also, three main challenges were identified: lack of visibility into system performance, difficulty in correlating data between systems, and slow response times to resolve issues.In summary, the research findings offer a comprehensive understanding of the present state of software testing, particularly within the domain of complex testing methods.The challenges reported and the perceived effectiveness of these methods serve as significant indicators of potential areas for enhancement and development.It is essential to acknowledge that these insights reflect the experiences and viewpoints of the survey participants, and further research could contribute to a more exhaustive grasp of the field.
