Amazing, right? Yes, if we can automate whole BVT process it can easily save around man-days on each iteration. Also, these automated processes are more reliable, and without manual errors. BVT is a surefire mechanism to ensure no regression defects have been introduced in DevOps methodology. Once build is uploaded, it will kick-off automated BVT plan.
These pre-defined VMs have the required software already installed. Once VMs are available, we have to verify that the required web application server and database software have been installed successfully. Many of the web application server have an option to install in silent-mode.
So if we find these five values then;. Nominal value can be any typical value that is far away from boundaries. For example, here we chose 50 as nominal but we can also choose 51, 52, 53, 49, 48 or any value that is typical value and far away from boundaries. As we see that 50 have a very large distance between 1 and 2. Similarly, 50 have a very large distance against 99 and This will reduce the probability of frequent build failure due to new unstable modules and test cases.
Right from build release process to BVT result — automate everything. Developers migh be doing the unit and intregration testing and not necessarily the BVT. BVT is most of the times done by test engineer. Once the build team deploys the test build on the test environments its the job of test engineer to perform BVT sniff, sanity smoke and other testing If you are able to test the applicaiton and are executing the test cases, its natural that the BVT has been passed.
If the build has got a new feature how can you automate it? In real life investigating all the test case failures requires huge amount of discipline and noticeable amount of intellectual effort.
Imagine thousands of test cases running on n different editions of your product. Every failure needs to be properly investigated and if applicable then bugs opened. Every single one of them. BVT is nothing but a set of regression test cases that are executed each time for new build. This is also called as smoke test. Build is not assigned to test team unless and until the BVT passes.
BVT process is typically automated by writing scripts for test cases. Only critical test cases are included in BVT. Build verification testing is failed is due to developer is not always true. There are many several reasons which cause failing BAT test case like:. Have you automated BVT in your testing career, if yes please share your experience with our readers in comments below.

Keys points to be considered while preparing build verification testing checklist : Build Verification Testing The success of BVT test is totally depends on what all test cases included in BVT. It should not take more time to execute the test. Timely Build Verification tests suite should be updated based on the functional changes in the application.
Purpose of this test is to save the time of test team if the main core features are not working or contains defects. Most of the defects are observed in the integration of the modules which are developed by different persons, so selection of test cases is very important.
