Regression testing should be performed?
Regression testing should be performed:a) after the software has changedb) when the environment has changedA) more effective and compartable bcoz most probably always software chnages first then env.
What is the difference between alpha testing and acceptance testing?
Alpha testing is always performed by the developers at the software development site. acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.
In testing for differences between the means of two related populations the null hypothesis is?
That there is no difference between the means for the two populations.
Difference between alpha testing and beta testing?
Alpha Testing is always performed at the time of Acceptance Testing when developers test the product and project to check whether it meets the user requirements or not.Beta Testing is always performed at the time when software product and project are marketed.
What is alpha in regression analysis?
Alpha is not generally used in regression analysis. Alpha in statistics is the significance level. If you use a TI 83/84 calculator, an "a" will be used for constants, but do not confuse a for alpha. Some may, in derivation formulas for regression, use alpha as a variable so that is the only item I can think of where alpha could be used in regression analysis. Added: Though not generally relevant when using regression for prediction, the significance level is important when using regression for hypothesis testing. Also, alpha is frequently and incorrectly confused with the constant "a" in the regression equation Y = a + bX where a is the intercept of the regression line and the Y axis. By convention, Greek letters in statistics are sometimes used when referring to a population rather than a sample. But unless you are explicitly referring to a population prediction, and your field of study follows this convention, "alpha" is not the correct term here.
What is the major difference between regression testing and retesting?
regression testing is a white box testng
What is difference between regression testing and retesting?
A regression test is a test where a previously known bug is tested for after a change. A retest is simply repeating a test.
What are the different types of regression testing?
Unit regression testing Regional regression testing Full regression testing
What is the difference between retesting and regression testing?
Retesting means testing the functionality or bug again to ensure the code is fixed. If it is not fixed, defect needs to be re-opened. If fixed, defect is closed. Regression testing means testing your software application when it undergoes a code change to ensure that the new code has not affected other parts of the software.
Testing to make sure software hasn't taken a step backwards or regressed is known as?
Regression testing.
How do you do regression testing?
Just like that

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.
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 the status of defect when performing regression testing?
fixed
What is difference between Maintainability testing and Maintance testing?
sorry
Prerequisites of Regression testing and system testing?
system testing is a kind of retesting where we can test whole system after integration. while regression testing is a process where we do the rerunning the test cases and check whether that re run doesnot affects the real environment.
