There is no fixed number of bug types, but common categories include functional bugs, performance bugs, security bugs, usability bugs, compatibility bugs, integration bugs, logic bugs, boundary bugs, localization bugs, and regression bugs.

What is the priority and severity of the bug? Explain with examples.

In software testing, priority and severity are key attributes used to classify and manage defects efficiently. Severity refers to the impact of the bug on the system’s functionality and priority indicates the urgency of fixing the bug based on business needs.

Examples of Priority and Severity in Bug Testing are:

  1. High Severity, High Priority: The login button is unresponsive, preventing users from accessing the system. This must be fixed immediately.
  2. High Severity, Low Priority: A rare crash occurs when using a specific feature that most users don’t access frequently. While the impact is severe, the fix can be scheduled for later.
  3. Low Severity, High Priority: A spelling mistake in the company’s name on the homepage. It doesn’t affect functionality but needs urgent correction due to branding concerns.
  4. Low Severity, Low Priority: A minor UI misalignment in the settings page, which does not impact usability. It can be fixed in future updates.

What is bug priority?

Bug Priority indicates how urgently a defect should be fixed based on its impact on business goals, user experience, and release timelines. It helps development teams decide which bugs to address first.

Who decides severity and priority in testing?

Severity is typically determined by testers or QA engineers based on the technical impact of the bug on the application’s functionality. Priority is usually set by project managers, product owners, or developers based on business needs, customer impact, and release timelines.

What is a blocker bug in software testing?

A blocker bug is a critical defect that completely halts the functionality of an application, preventing users from proceeding further. It must be fixed immediately as there is no workaround.

How does QA Touch help in managing bug severity and priority?

QA Touch helps teams efficiently track and manage bugs by allowing testers to categorize defects based on severity (impact on functionality) and priority (urgency of fixing). It enables collaboration between testers, developers, and managers to ensure that critical issues are resolved first. With features such as customizable workflows, integrations with Jira and Bugzilla, and detailed reporting, QA Touch streamlines defect management, helping teams prioritize and fix bugs effectively.
