Quick Guide to Build Verification Testing: Best Practices and Tips
Updated on: 12/12/24
10 min read
Imagine you’ve just finished building a new feature for your software application. Exciting, right? But before you jump into extensive testing, you need to ensure that the basic functions are working correctly. This is where Build Verification Testing (BVT) comes in. Think of BVT as your first line of defense, catching critical issues early and ensuring that your build is stable enough for deeper testing.
Build Verification Testing, sometimes called smoke testing, is a crucial step in the software development process. It saves time and resources by identifying major problems right at the beginning. If a build passes BVT, it means you can proceed with more confidence, knowing that the core functionalities are intact. If it doesn’t, it goes back to the developers for fixing, preventing unstable builds from moving forward.
In this guide, we’ll explore the best practices and tips for effective Build Verification Testing. Whether you’re new to BVT or looking to refine your process, these insights will help you enhance your testing strategy, improve product quality, and keep your development cycles running smoothly.
What is Build Verification Testing?
BVT is a subset of tests that focus on the core functionalities of the software application. It aims to verify whether the latest build is testable and stable before it proceeds to the detailed testing phases. This process helps in identifying any immediate defects that could hinder further testing, saving time and resources in the long run.
Process of Build Verification Testing (BVT)
Receive New Build:
The BVT process initiates when a new build is delivered from the development team. This build contains recent changes or updates to the software application, such as new features, bug fixes, or performance improvements. The test team receives notification that the build is ready and available for testing.
Execute BVT Test Suite:
The BVT test suite is a collection of automated tests designed to quickly verify the core functionalities of the application. These tests cover critical areas to ensure that the build is stable and that fundamental features work as expected. The test suite is executed against the new build, typically using continuous integration (CI) tools to automate this process.
Examine Results:
After the BVT test suite is executed, the results are collected and analyzed. The test lead or manager reviews these results to identify any defects or issues that might have been introduced in the new build. This step is crucial for determining whether the build is stable enough to proceed with more exhaustive testing.
Report and Fix Defects:
If the BVT test suite identifies any defects or issues, these are documented and reported to the development team. The defects are logged into a tracking system with detailed information to help developers understand and reproduce the issues. The development team then works on fixing these defects to ensure the build meets the required quality standards.
Re-test:
Once the development team fixes the reported defects, a new build is generated. This updated build undergoes another round of BVT. The BVT test suite is re-executed to verify that the fixes are effective and that no new issues have been introduced. This iterative process continues until the build passes all BVT tests without any critical defects. When the build is stable and passes the BVT, it is deemed ready for more comprehensive testing phases, such as regression testing, system testing, or user acceptance testing.
Benefits of BVT
Build Verification Testing (BVT) plays a crucial role in the software development lifecycle by ensuring that each new build is stable and ready for further testing. Here are some key benefits of BVT:
Early Detection of Defects:
One of the primary advantages of BVT is the early detection of critical defects. By running a predefined set of test cases on each new build, teams can quickly identify major issues that could hinder further testing. This early detection helps in addressing problems promptly, saving valuable time and resources.
Time and Resource Efficiency:
BVT helps in conserving the time and effort of the testing team. Ensuring that only stable builds are passed on for extensive testing prevents the team from wasting time on builds that are not ready for thorough testing. This focus on stability enhances overall productivity and efficiency.
Immediate Feedback to Developers:
When a build fails the BVT, immediate feedback is provided to the development team. This feedback loop is crucial for rapid bug fixing and continuous improvement. Developers can quickly diagnose and resolve issues, leading to faster turnaround times and more robust builds.
Increased Confidence in Build Stability:
By regularly performing BVT, teams gain confidence in the stability of their builds. This confidence is particularly important in agile environments where frequent builds and continuous integration are common practices. Knowing that each build has passed a rigorous set of tests ensures that subsequent testing phases can proceed without major disruptions.
Improved Quality of Software:
BVT contributes to the overall quality of the software by verifying core functionalities early in the development process. This proactive approach to testing helps maintain high standards of software quality, reducing the likelihood of critical issues surfacing later in the development cycle.
Streamlined Testing Process:
Incorporating BVT into the development workflow streamlines the testing process. It establishes a clear, repeatable procedure for verifying new builds, ensuring that testing is systematic and consistent. This structured approach simplifies test management and enhances the reliability of the testing process.
Sample Test Cases for Build Verification Testing
To illustrate the application of BVT, here are some sample test cases:
Test Case 1: Application Launch
Objective
Verify that the application launches successfully.
Steps:
1. Install the latest build of the application.
2. Launch the application.
3. Verify that the application opens without errors.

Verify that users can navigate through key sections of the application.
Steps:
1. Log in to the application.
2. Navigate to the 'Settings' section.
3. Navigate to the 'Profile' section.

Challenges and Solutions
Frequent Changes in Requirements:
Regular updates to the application can affect the BVT tests. Solution: Regularly update and maintain test cases.
Integration Issues:
It might fail due to issues in integrating different modules. Solution: Include integration tests in the BVT suite and ensure proper communication between development teams.
Automation Maintenance:
Maintaining automated tests can be challenging. Solution: Use reliable automation tools and frameworks that support easy maintenance and updates.
Best Practices for Build Verification Testing
Develop a BVT Plan:
Outline the objectives, scope, and test coverage in a detailed plan to ensure all team members are aligned with the testing goals.
Define Clear Criteria:
Establish clear entry and exit criteria for BVT, including conditions under which a build is accepted or rejected based on test outcomes.
Automate BVT Tests:
Automation is crucial for BVT as it ensures quick and consistent execution of tests. Tools like BotGauge facilitate easy automation and maintenance of BVT test cases.
Focus on Core Functionalities:
BVT should cover the critical functionalities of the application, such as user login, basic navigation, data input, and retrieval processes.
Keep Tests Short and Effective:
BVT tests should be concise and executed within a short time frame (ideally 30 to 60 minutes) to provide quick feedback on the build’s stability.
Regular Updates and Maintenance:
Regularly update test cases to reflect changes in the application. Remove outdated tests and add new ones as required to ensure relevance.
Detailed Logging:
Maintain comprehensive logs for all test executions. This helps in diagnosing failures and understanding test outcomes for more effective debugging.
Include High-Risk Areas:
Allocate more test cases to high-risk areas to thoroughly verify and mitigate potential risks, ensuring that the most vulnerable parts of the application are stable.
Integrate with CI/CD:
Integrate BVT into your CI/CD pipeline to automate the testing process and ensure continuous feedback on build stability.
Monitor and Analyze Results:
Regularly monitor test results and examine failures to identify recurring issues. This helps in improving the overall quality of the build by addressing the root causes of defects.
