A Comparative Analysis of Manual Versus Automated Software Testing: Efficiency, Effectiveness and Practical Applications

Abstract

This research proposes a detailed and comparative analysis between manual and automation software testing. The quick advancements and modernization in software industry have discovered the need for efficient and effective software testing methodologies. This thesis, titled "A Comparative Analysis of Manual Versus Automated Software Testing: Efficiency, Effectiveness, and Practical Applications," explores the advantages and limitations of manual software testing and automated software testing approaches in detail with aiming to provide useful information which can be implemented in software industry into their suitability for modern software quality assurance and software engineering environments. The detailed study and research is conducted by adopting a mixed- methods methodology, which included both quantitative and qualitative analysis and investigations. Real-world professional test scenarios were designed and executed for two distinct software domains that airline ticketing system and a hospital inventory management system. These software systems were directed to manual software testing and automated software testing using professional industry-standard automation tools and frameworks such as Selenium and Cypress. In this study there is research conducted on performance metrics which include efficiency with time, cost and resource usage, effectiveness with bug detection rate, test coverage and reliability and then practical applications for professional real- world scalability and adaptability. The key findings of this study states that automated software testing significantly beats manual software testing in terms of efficiency, execution speed, cost per test cycle, resource usage and test coverage. Automated testing tools gives higher bug detection rates and scalability, making this approach suitable for large-scale, repetitive testing and regression testing scenarios. But on the other hand, manual software testing remains useful for exploratory testing, ad-hoc testing and scenarios where human judgment is required. Through deep statistical analysis, including our own proposed algorithm and t-test, the research validates and justifies the superiority of automated software testing in most of the metrics while acknowledging the important roles of manual software testing.
