What is regression testing? It is a testing method that is performed to ensure that despite making any changes, modifications and updations to the code, the existing functionalities of the software application are working as expected. The overall functionality and stability of the existing features are tested using this testing method. Test cases that have been already executed are partially or fully selected and then re-executed in order to make sure that the existing functionalities are working as expected. What is integration testing? It is a testing method where different software modules are validated based on how they function when they are combined, especially in terms of performance and effectiveness. The focus is on finding defects when these software modules that have been coded by different programmers interact with each other. How the data is being communicated amongst these modules is thoroughly checked.                 Difference between regression testing and

Following are the four common challenges of regression testing: 1. It is considered to be quite complex: While the software development project is ongoing, the application of regression tests can tend to become complicated. In certain scenarios, there could be thousands of test cases, processes and functions that need to be checked, and it may become highly difficult or impossible for QA engineers to perform these tests manually. In order to solve this issue, certain companies might opt for automated regression testing. 2. A lot of resources are required: The concept of regression testing implies that it should be able to run after every development iteration. But, when it comes to justifying the time required for running the tests, it becomes a really difficult task to perform the testing process. In order to solve this issue, external teams or crowd testers or both can be held responsible for executing these test cases, which will, in turn, help relieve the internal testing team t

Sanity testing and smoke testing have their own strategic value in the software development process. Though both these testing types are being confused at some point or the other, but, if a thorough study is done for both these testing types from a practical standpoint, then the testing team can truly leverage these two valuable testing methods. Both these testing types have their specific testing objectives and priorities that need to be met. In this article, you will get a brief idea about sanity and smoke testing and also the differences between both of them. What is sanity testing? When the software build is received, sanity testing is performed in order to ensure that the code changes that have been done are working as expected. This testing method evaluates whether the testing for a specified build can be done or not. The functionality of the application is validated. It decides whether a specific software product should go through end-to-end testing or not. A build is tested whe
