SWE30009 Assignment 1: Critical Review of Software Testing Paper

This report presents a critical review of the research paper "Metamorphic Testing for Software Quality Assessment: A Study of Search Engines" by Zhou et al. (2015). The review analyzes the paper's exploration of metamorphic testing (MT) as a method to assess software quality, particularly in the context of search engines. The paper's core argument revolves around MT's ability to address the oracle problem in software testing, where an oracle is needed to determine if the test results are correct. The review highlights the main points of the paper, including its discussion of MT's advantages in reducing complexity and improving performance compared to conventional testing. It also critically evaluates the research methodologies employed, the advantages of the study, such as the in-depth analysis of MT and its impact on software quality, and the disadvantages, such as the lack of surveys and limited information on MT's limitations. The review also examines the paper's systematic literature review and its contribution to understanding the significance of MT in software development, while also providing references to related studies.
