Master Thesis: "Development of a Web Recorder for Automating Tests on Web Applications" Undertaken in my final 10th semester, the objective of this thesis was to develop open-source software capable of capturing user actions on a website for subsequent replication in user acceptance tests. The tool comprehensively logs details like HTML, CSS, JavaScript code, API calls, content, and webpage snapshots. User actions are recorded via a Chrome extension, while test results are visualised through a dedicated web application. Throughout this project, I honed skills in JavaScript, Node.js, HTML, CSS, Web Development, Chrome Extensions, MEAN stack, Angular, Docker, and more.
