PurifyPLUS > Dynamic Software Analysis

PurifyPlus software is a complete set of run-time analysis tools designed for improving application reliability and performance. The PurifyPlus software combines memory error and memory leak detection, application performance profiling, and code coverage analysis into a single, complete package. Together, these functions help developers ensure the highest reliability and performance of their software from its very first release. (Developers also have the option of using PurifyPLUS software, which can be purchased separately, for a dedicated memory error and memory leak detection tool set. The PurifyPlus solution adds performance profiling and code coverage analysis capabilities.)

Highlights

Identifies untested code
Instruments an entire application or only selected modules
Supports Microsoft Windows, UNIX and Linux environments
Supports Java, all managed Visual Studio .NET languages, Visual C/C++, Visual Basic and ANSI C/C++
Works with or without source code

PurifyPlus is a runtime analysis tool suite that monitors your program as it runs and reports on key aspects of its behavior:

How much memory does it use?
Does it leak memory?
Does it contain memory access errors?
How long does it take to run; where are the bottlenecks?
What is the thread running/sleeping behavior?
How much of the source code is actually running?

These key analysis features are all separate from the core "correctness" question: "Does it work?" and "Does it produce the right answers?" Testing can show whether your program works at all, but it takes runtime analysis tools like PurifyPlus to bring all these types of problems to light.

The major components of PurifyPlus are:

Purify for memory usage tracking and memory error detection
Quantify for performance analysis, code flow, and thread visualization
PureCoverage for source code coverage analysis
