Retesting and Regression testing are the two important practices that are often confused by the testing teams. Though the approaches are different, these effectively help in improving the quality of the software as the bugs are resolved, and the changes made into the code are ensured for not affecting the code and features of the software.
Are you confused about retesting and regression testing? This is one of the common queries for many in software testing. Retesting and Regression testing are the important concepts that every tester should be aware of before performing them. These methods are significantly used to improve the quality of the software. Hence, it is essential for the testing teams to understand what they are before stepping ahead.
What is Retesting?
Retesting is performed when a defect is identified and fixed. This is processed to ensure whether the originally found defect is resolved or not; also, this method is commonly known as confirmation testing. In this method, the test cases are planned with proper steps. The test cases which were failed earlier due to bugs are retested by replicating the same scenario with different approaches. With this method, teams can be ensured that the issues are fixed and the software can function as expected. And, it should be noted that the retesting test cases cannot be automated.
When do retesting is needed in software testing?
The scenarios where retesting is needed in software testing are:
What are the advantages of Retesting?
A few of the advantages of retesting are:
What is Regression Testing?
Regression testing is performed when there is a change made into the code. With the practice of regression testing, teams can ensure that the change made in the code is not affecting the other software parts. The main purpose of this method is to identify the bugs that are caused when new changes or modifications are made into the application.
Testing is essential when there are modifications and constant changes made into the code, if they reflect any issues then these can degrade the quality of the application. Hence, to avoid such scenarios, regression testing is essential and it should be performed by prioritizing the test cases based on the changes made.
When should the regression testing be practiced?
The scenarios where regression testing is practiced are:
What are the advantages of regression testing?
The advantages of regression testing are:
What are the key differences between regression testing and retesting?
Regression Testing
Re-Testing
It helps in validating that the change or enhancement made into the code is not affecting the existing code and features
It is performed to confirm that the test cases which have failed earlier have passed the final execution without any defects
This method is not responsible for identifying defects
In this method, defect verification is part of retesting
It is also known as generic testing
It is also known as planned testing
It ensures that there are no unexpected effects
It ensures that the error is resolved and not occurred again
The test cases for this method can be achieved from user manuals, functional specifications, etc.
The test cases for this cannot be achieved until the testing is practiced
It is performed for the test cases that are passed.
It is performed for the failed test cases.
The test cases can be performed with automated testing tools because manual methods can be time-consuming and expensive
The test cases cannot be automated
It can be processed in parallel with retesting.
Test cases are carried out before regression testing.
Conclusion:
Retesting and Regression testing are two important testing methods in the software testing process. Though the approaches are different, these effects help to produce quality software at the end of the testing practice. Leverage the retesting and regression testing methods from QA experts for driving a quality application.
What is ETL Testing Process and Tools?
Organizations in order to perform meaningful business analysis gather data from multiple sources. Popular Business Intelligence (BI) tools can be used for processing large amounts of data, so that valuable business insights can be obtained. To carry out this process meticulously, ETL (Extract, Transform, Load) testing is required. In this article, you will know about what is ETL testing process and the various ETL testing tools.
Why is it important to use regression testing?
Today every business needs high-quality software to deliver a seamless experience to customers. And to improve the quality of software businesses make frequent changes in the software which sometimes affects its existing functionality. The affected functionalities hamper the smooth functioning of software which ultimately hampers UX. Therefore to identify and fix issues regression testing method is used. Let’s now try to understand more about regression testing.
Different types of Security testing
Data is considered to be one of the most vital aspects of an organization. If the data is not secured, then chances are intruders or cyber attackers will try to exploit the data for their own benefit, which in turn can prove to be a huge loss to an organization. Hence, performing security testing to test and evaluate the information security system of an organization is considered to be a really important activity. In this article, you will get to know some of the important types of security testing.
