What is execution tracing?
Tracing collects information about what is happening in your program and displays it. If a program arrives at a breakpoint created with a trace command, the program halts and an event-specific trace information line is emitted, then the program continues.
What is execution trace in software testing?
The execution traces present the order of the statements that are touched during the execution of the test cases. The execution logs present the output of each test case, i.e., whether it passed or failed.
How do I trace a program in C++?
To define tracing functions in C++ programs, use the extern “C” linkage directive before your function definition. The function calls are only inserted into the function definition, and if a function is inlined, no tracing is done within the inlined code.
How can I trace the execution of an application?
You can also trace code execution in an installed application, using methods of the Trace class. By placing Trace Switches in your code, you can control whether tracing occurs and how extensive it is. This lets you monitor the status of your application in a production environment.

When to use WPP Software tracing and Event Tracing for Windows?
For a comparison of the two approaches to instrumenting your code, see When to Use WPP Software Tracing and Event Tracing for Windows (ETW). The tools also can access reserved trace sessions that are built into Windows, such as the Global Logger trace session / NT Kernel Logger trace session.
Are there any tools that support software tracing?
The tools support a variety of trace providers, including user-mode applications and kernel-mode drivers, which are instrumented for software tracing by using WPP software tracing or ( Event Tracing for Windows (ETW).
