To support and enhance your testing and maintenance practices, you can use various tools that can help you to automate, manage, and monitor your QA processes and products. Test automation tools, such as Selenium, TestComplete, or Katalon Studio, can create, execute, and maintain automated tests for your software, across different platforms, browsers, and devices. Test management tools, such as Jira, TestRail, or Zephyr, can organize, track, and report test cases, test plans, test results, and test metrics, as well as integrate with other tools and systems. Code quality tools, such as SonarQube, CodeClimate, or Codacy, can analyze, measure, and improve the quality and security of your code, by detecting and fixing code smells, bugs, vulnerabilities, or technical debt. Configuration management tools, such as Git, SVN, or Mercurial, can control, manage, and version your code, as well as collaborate with other developers and testers. Continuous integration and delivery tools, such as Jenkins, Travis CI, or CircleCI, can automate and streamline build, test, and deployment processes, as well as ensure the quality and consistency of your software throughout the development lifecycle.
