I absolutely love this. Keep updated! If software quality drops between two consecutive iterations of the component, runtime analysis data makes it very easy to find the responsible feature or code change. Runtime analysis for program understanding Sometimes runtime analysis isn't about correctness or quality at all. For example, runtime analysis can help with program understanding. Quantify, in particular, can show a call graph that reveals how the pieces of a program fit together, or it can reveal surprising paths that can explain unexpected performance degradations or interactions.
As noted above, PurifyPlus has three major components: Purify for memory analysis, Quantify for performance analysis, and PureCoverage for code coverage analysis. All of these are software quality issues that can lurk in a program even if its tests all pass. Problems like this can cause expensive failures in production after you release the product. For Java and Microsoft. Net programs "managed programs" , Purify tracks memory usage and memory references so you can see where your memory bottlenecks are, see where you are holding memory you ought to release, and compare before-and-after images to detect unintended increases in memory usage "leaks" in the program.
Quantify tracks program performance and calling behavior, so you can see execution flow and identify bottlenecks.
Quantify highlights code paths that take the longest, using the River of Time tm feature. In addition, Quantify lets you visualize thread execution behavior in your program. PureCoverage tracks code coverage, so you can identify gaps in your testing and areas of your program that the runtime analysis tools are not seeing.
Since Purify and Quantify only see the code that actually runs, the code coverage metrics provided by PureCoverage are critical to knowing that you are verifying and improving quality across your whole project. PurifyPlus for Windows: A dynamic software analysis toolset for Windows application development. The following information lists the basic software requirements for using PurifyPlus for Windows.
The major goals of debugging are to find the root cause of defects and understand application behavior. This particular view shows the source file of the examined application; the color of the line indicates the line's status after the executed test case: hit, missed, dead, or partially hit.
The code fragment in Figure 1 shows the exact path the application took when executing the switch statement on line This particular line is marked as partially hit because line hasn't been executed. Figure 1: PurifyPlus display of annotated source for the C. NET application in Visual Studio. A runtime analysis tool such as Quantify included in PurifyPlus provides thread visualization, which can assist in detecting multithreading problems by marking the state of each of the threads while debugging.
As Figure 2 shows, this allows you to examine the status of threads visually, while debugging. Figure 2: Quantify thread analysis view in Visual Studio 6. Runtime analysis tools can also detect and display performance bottlenecks. The big advantage of this approach, compared to traditional methods, is that you can get an excellent overview of the execution path as well as precise information about the number of calls to the methods involved in the scenario.
As Figures 3A and 3B show, the Call Graph in Quantify highlights a chain of calls in the most time-consuming execution path; that is the performance hotspot. The thickness of the line connecting methods is proportional to the ratio between the time or memory if you are using Purify spent in this chain of calls and the rest of the application. Figure 3A: Quantify call graph of a mixed VB. NET and C. The first step in handling memory leaks is to detect them. One very intuitive way to do this is to visualize overall memory usage and take snapshots of memory in the program under test PUT.
This lets you see potential memory leaks in the running application. This feature is available in Purify for Java and. NET managed applications. For example, if snapshots of memory usage for the component running on the server show that overall memory usage increases after each client session, then it is very likely that this component leaks memory see Figure 4.
Figure 4: Overview of thread status and memory usage in Purify for Windows. Visual error detection is just the first stage of runtime analysis. We also need to understand exactly what happens during the run.
For that purpose, runtime analysis should be based on exact measurements of parameters vital for the application's execution:. Function List View is a typical runtime analysis view that can be generated with a specialized Runtime analysis tool such as Quantify see Figure 5. This view provides exact information about the number of calls to methods, time spent in methods only, time spent and memory accumulated in selected methods and all their descendants, and so on.
A runtime analysis tool such as Quantify can also extend the information in Measurement Example 1 to include information about the distribution of measured data between calling methods and descendants. This is shown in the Function Detail View Figure 6.
