Testing to make sure software hasn't taken a step backwards or regressed is known as?
Regression testing.
What is the major difference between regression testing and retesting?
regression testing is a white box testng
What is full regression testing?
Regression testing is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes such as enhancements, patches or configuration changes, have been made to them.

How create a regression suite when a defect is fixed?
To complete testing application if any modification done any modules or functionality that is called regression testing.
What is the status of defect when performing regression testing?
fixed
In software testing regression testing must consist of fixed set of test to create a base line is it true or false?
Regression are classified as - Full / Complete Regression -- Entire application is regressed - Regional regression -- Tests performed around defect fixes or code changes
What is regression testing with example?
Regression testing is an iterative process executed throughout the software development and testing cycle. Regression testing focuses on previously tested aspects, features which were tested and found working, or bugs which were found and confirmed fixed, in earlier versions of the software. The purpose of regression testing is to make sure that those previously verified features still work. For example, consider a software release that includes two new features, A and B. While the developers are still working on feature B, test is already examining feature A. When A is found working as planned, testing proceeds to feature B, while regression testing affirms that nothing in feature B broke A.
Explain how the use of automated tests and a testing framework such as JUnit simplifies regression testing?
Regression testing is the process of running tests for functionality that has already been implemented when new functionality is developed or the system is changed. Regression tests check that the system changes have not introduced problems into the previously implemented code. Automated tests and a testing framework, such as JUnit, radically simplify regression testing as the entire test set can be run automatically each time a change is made. The automated tests include their own checks that the test has been successful or otherwise so the costs of checking the success or otherwise of regression tests is low. Involves building a system from its Testing is an expensive process phase. Testing workbenches provide a range of tools to reduce the time required and total testing costs. Systems such as Junit support the automatic execution of tests. Most testing workbenches are open systems because testing needs are organization-specific. They are sometimes difficult to integrate with closed design and analysis workbenches components and testing it for problems that arise from component interactions. Top-down integration: Develop the skeleton of the system and populate it with components. Bottom-up integration: Integrate infrastructure components then add functional components. To simplify error localization, systems should be incrementally integrated.
What types of inferences will you make about population parameters?
Estimation regression testing
