The document discusses Parasoft's tools for preventing Java software defects through automated analysis techniques including static code analysis, runtime error detection, and automated unit test generation. It outlines specific features such as application tracing, data flow analysis, and regression testing, aimed at identifying and resolving various coding issues. Additionally, it highlights the importance of capturing current code behavior and adjusting unit tests accordingly to enhance software quality.

- 4. The Problem Report Similar Items not Aggregating in Shopping Cart Add one item to the cart Add the same item again Expected: a single line item with quantity 2 Found: 2 line items each with quantity 1 Parasoft Proprietary and Confidential
- 5. Application Tracing for Unit Tests Record internal method calls inside the running application when the problem occurs Replicate the problem in a JUnit test Alter the JUnit test to assert the correct behavior Now possible solutions can be tested quickly without redeploying the web application Parasoft Proprietary and Confidential
- 6. Pattern-Based Static Analysis Quick scan to list possible problems Fixing violations prevents certain classes of errors Each source file is analyzed separately Static analysis categories include: Logical Errors API Misuse Typographical Errors Security Threads and Synchronization Performance and Optimization Parasoft Proprietary and Confidential
- 7. Runtime Error Detection Check for anti-patterns at runtime in the application Violations are presented in the context of real- world data values to stress their importance Runtime error categories include: Threads and Synchronization Performance and Optimization Application Crashes Functional Errors Security Parasoft Proprietary and Confidential
- 8. Automated Unit Test Generation Test code branches not covered by the application-level test Combine these unit tests with runtime error detection to check the new execution paths Build a baseline regression test suite Parasoft Proprietary and Confidential
- 9. Data Flow Analysis Simulate hypothetical execution paths Detect possible errors along those paths Data flow analysis error categories include: Exceptions Optimization Resource Leaks API misuse Security Parasoft Proprietary and Confidential
- 10. Regression Testing Capture current behavior of covered code paths Whether the current behavior is right or wrong Alert when code modifications cause a change in behavior Developers can then mark JUnit assertions as correct behavior to increase the severity if those assertions fail in the future Parasoft Proprietary and Confidential
