Overview
Open Source testing tools are being used aggressively and there are many tools over the web for Java Applications. These tools are great asset to the development teams and provides many features / services over the quality of applications under development. We can use this as the starting point and focus more efforts on the uncovered areas for better quality.
It’s very important to know the context of development and the right tools for quick benefits. However, heavy usages of these tools lead to misleading data and metrics too. So think twice on what is required for the project and which tools might provide the required data / services.
Services Offered
The following services / features are offered from most of the open source tools
- Continuous Integration for the builds
- Unit Testing
- Code Coverage
- Source Code Metrics (like size, Complexity, design, dependency)
- Static Analysis for various bug patterns
- Test Automation
- Performance Testing
List of Open Source Tools
- Functional Testing
- Unit Testing
- Performance Testing
- Test Management
- Security testing
- Bug databases
- Link Checkers
- Open Source Testing Tools from Java Source
- Web Testing Tools
Quick Benefits from Static Analysis
It’s very easy to integrate static analysis tool(s) with builds and there quick benefits. The following issues can be uncovered
- Null Pointer Exceptions
- Other un handled exceptions
- Infinite Loops
- Dead code
- Compliance with Java Coding standards
- Code Coverage data
- Trends / history on the above checks against previous builds
- Validations against Java coding guidelines from Sun
The following Metrics can be captured
- Source Code Metrics
- Coverage Metrics
- Dependencies with the Design
- Code complexity metrics
The Resources listed below helps in implementing the same.
