Our Approaches For Regression Testing

Taking Regression Testing from Siznam not only ensures the stability, security, and reliability of your software but also makes certain that no part of your software has been untouched. 

Siznam believes in delivering quality services at a price so minimal that it feels like a dime a dozen. Our team of QA professionals uses several exotic approaches for Regression Testing that check every tiny bit of your software to look for new malfunctions resulting in bug eradication procedures. Currently, we are ready to serve you with

Sanity Testing

In this testing, the software is tested to see its overall health and stability which helps to check if the software could go under further testing and changes. Sanity Testing is often performed to look for any potential bug or affected areas that might have been produced due to already conducted testing and fixes. Sanity Testing makes sure there are no bugs or defects that could cause problems when the product undergoes excessive regression testing.

Corrective Regression Testing

Corrective Regression Testing helps in checking software, applications, and websites that if the previous testing and correction procedure has introduced new defects in the product. During the bug removal procedure, several types of changes are made like code changing or providing fixes to the problems. Corrective Regression Testing helps to check if these procedures have affected any other function of the product.

Progressive Regression Testing

In Progressive Regression Testing, we create new test cases according to the modifications done to your product. These new test cases are designed to address the newly made changes in your software, websites, and applications to make sure that the already made changes haven’t produced new defects in the products. This testing helps to make your products more reliable and stable by checking for every kind of defect introduced due to the bug removal procedure.

Partial Regression Testing

After new code is added to the already existing code of the product, or changes are made in the main code of the product, Partial Regression Testing is performed. In this, we only use a smaller part of the already existing test cases to save time and money. Instead of applying or using the whole test suite, only a fractional part of the test case is used on those parts of the products which are more likely to get affected after the testing is done.

Unit Regression Testing

In this testing, we focus on individual units of the code to look for any newly introduced malfunction. In Unit Regression Testing, code units are tested in isolation after changes are made in it to remove potential bugs. In this testing, we check your application, website, or software on a unit level to see if any changes made in units have introduced new defects in already existing units of the products making it more reliable even from the unit level.

Selective Regression Testing

Selective Regression in Software Testing is performed on the new code after any kind of changes have been made in the previous code. In this testing, a subset of the test suite is applied to the product to look for any affected area due to bug removal. This usage of the subset saves time as well as the overall cost of the testing procedure by focusing and testing only those parts which are most likely to be affected making the regression procedure more reliable and effective.

Functional Regression Testing

In this testing, the functionality of the software is checked to look for any defect that might have occurred due to already-done testing or bug removal procedure. Functional Regression Testing clearly focuses on checking functionality defects of the software and ensures that there is no malfunction in the app's existing functionality.

Complete Regression Testing

In this testing, we execute all available tests of regression testing. Complete Regression Testing is the final type of testing that is conducted at the last to look for any defected area and after that, the product becomes ready to be launched. In this testing, all the test suites available in regression testing are executed to check the product. This testing is done when a large number of changes in code have been made and there are chances of occurrence of new defects.

Retest-all Regression Testing

Retest-all Regression Testing is the most extensive form of regression testing that we provide. In this testing, we check your software for any defects from the very initial level to make sure nothing has gone unseen and unchecked. This testing ensures your product has been thoroughly checked and is completely functional. Retest-all regression testing is to ensure that every executed test is checked and has caused no problem in the proper functionality of the app making it more streamlined.
