Instrumentada

Instrumentada is a term used in the field of software testing to describe a process where the software under test is modified to facilitate testing. This modification typically involves adding code to the software that allows for better control, observation, and measurement of its behavior. The primary goal of instrumenting software is to improve the effectiveness and efficiency of testing, enabling testers to identify and fix defects more quickly and accurately.

Instrumentation can take various forms, including adding logging statements to track the flow of execution, inserting probes to monitor performance metrics, or incorporating hooks to intercept and manipulate function calls. These modifications are usually temporary and are removed once the testing is complete, ensuring that the production version of the software remains unaltered.

The process of instrumenting software can be automated to some extent, using tools that analyze the code and automatically insert the necessary instrumentation points. However, manual intervention is often required to ensure that the instrumentation is correctly placed and does not interfere with the normal operation of the software.

Instrumentada is particularly useful in scenarios where the software's internal state is difficult to observe or control, such as in embedded systems, distributed systems, or applications with complex user interfaces. By providing a clearer view of the software's behavior, instrumentation can help testers identify issues that might otherwise go undetected, leading to more robust and reliable software.
