What is called regression?

Regression refers to the process of testing a software application to ensure that recent changes or enhancements have not introduced new defects or caused existing functionality to regress. For example, if a new feature is added to a website, regression testing would involve testing existing functionalities to ensure they still work as expected.

What are the types of regression testing?

The types of regression testing include:

Unit regression testing:

  • Testing individual units of code to verify their correctness after modifications.

Partial regression testing:

  • Testing a subset of functionalities that are likely to be affected by recent changes.

Full regression testing:

  • Testing the entire application to ensure all functionalities are working as expected.

What is regression testing with example?

Regression testing involves retesting previously tested functionalities to ensure their continued correctness. For example, if a bug was fixed in a software application, regression testing would involve retesting the specific area where the bug occurred to ensure it has been resolved and does not reappear.

What are the 3 techniques of regression testing?

The three techniques of regression testing are:

Retest all: Testing all functionalities of the software application after modifications.
Regression test selection: Selectively testing specific functionalities that are likely to be affected by the changes.
Prioritization-based regression testing: Prioritizing test cases based on their importance and executing them accordingly.

What is regression vs UAT?

Regression testing focuses on ensuring the existing functionality of the software is not affected by recent changes. On the other hand, User Acceptance Testing (UAT) involves testing the application from an end-user’s perspective to ensure it meets the requirements and expectations.

What is regression in Agile?

In Agile development, regression refers to the process of continuously testing and verifying existing functionalities to ensure they have not regressed due to new changes or additions in each iteration or sprint.

What is regression testing in QA?

In QA (Quality Assurance), regression testing involves testing previously tested functionalities to ensure they have not been affected by recent changes. It helps maintain the quality and stability of the software application.

What is Sprint testing?

Sprint testing refers to the testing activities performed within a specific iteration or sprint in Agile development. It involves testing the new features or changes made during that sprint to ensure they meet the defined requirements and do not cause regressions.

What is regression in a Jira ticket?

In a Jira ticket, regression refers to a specific issue or bug that has resurfaced or reoccurred after it was believed to be fixed or resolved. It signifies that the software has “regressed” back to a previous problematic state.

What is a regression testing tool?

Regression testing tools are software applications or frameworks designed to automate and streamline the process of regression testing. These tools help in executing test cases, comparing expected and actual results, and identifying any regressions in the software application. Examples of regression testing tools include Selenium, JUnit, and TestComplete.
