Jira software testing involves using Jira, an issue and project management tool, to plan, execute, and monitor software testing activities. Testers use Jira to create and manage test cases (often with plugins like Zephyr or Xray), log and track defects, assign tasks, monitor test progress, and generate reports. It supports Agile and DevOps workflows by enabling collaboration between testers, developers, and stakeholders, ensuring transparency, traceability, and efficient quality management throughout the software development lifecycle.
