Project keys
Project keys are a series of alphanumeric characters that describe to people across your Jira site what pieces of work are related to your project. They’re the most memorable and recognizable piece of an issue’s identifier. For example, our team is codenamed Donut World. We use the project key “DONUT” to help people across Atlassian know and recognize work that relates to our team.
JIRA Issues
JIRA is a popular issue-tracking tool that can be used for software testing. It allows you to track bugs, defects, and other issues in your software development process. JIRA issues can be used to track the progress of your testing, identify and prioritize defects, and communicate with your team.
