TestNG, a popular open-source testing framework designed to overcome the limitations of older systems like JUnit, is particularly beneficial for integrated class testing due to its support for annotations, grouping, and parametrization. This article explores how TestNG can be used to generate reports in Jenkins, a continuous integration tool, by utilizing the TestNG Results Plugin, which offers a detailed XML report of test outcomes. The integration allows users to publish these reports and share them via email notifications, enhancing the collaborative aspect of automated testing. The process begins with creating a TestNG project, installing Jenkins and the TestNG plugin, and configuring Jenkins to run TestNG tests and generate reports, which can be shared with team members to streamline the testing workflow. The article also provides insights into the importance of TestNG annotations in structuring test cases and highlights the flexibility provided by Jenkins in generating and distributing test reports.
