Software testing courses can help you learn test planning, test case design, automated testing, and performance testing. You can build skills in identifying bugs, writing effective test scripts, and using various testing methodologies. Many courses introduce tools like Selenium for automation, JUnit for unit testing, and JIRA for issue tracking, showing how these skills apply in real-world software development environments.
