A software testing course provides comprehensive training on how to test software applications for bugs, defects, and functionality. It covers key concepts such as manual testing, where testers execute tests without automation, and automation testing, which involves using tools like Selenium or JUnit to automate test cases. The course typically includes topics like test planning, writing test cases, bug tracking, and types of testing (e.g., functional, performance, regression). Additionally, hands-on practice with real-world projects and tools is emphasized, equipping learners with practical skills to pursue roles like QA tester, automation engineer, or software quality analyst.
