What are the main methods of analyzing problems that arise during testing?

Stack Trace Analysis. Allows determining the sequence of function calls that led to an error.

Log Analysis. Viewing system, server, and client logs to identify anomalies, errors, and warnings.

Comparison with expected behavior. Matching the actual test execution result with predefined expectations.

Deduction and induction. Using logical reasoning to localize the cause of the problem.

Problem Isolation. Narrowing down the search area by sequentially excluding factors.

Step-by-Step Execution. Reproducing the scenario with detailed observation of each step.

Database Data Analysis. Checking the state of data in the database related to the reproducible bug.

Using Debuggers. Connecting to the application to step through the code, view variable values, and function calls.

Network Traffic Analysis. Checking requests and responses between client and server using tools like Wireshark or Fiddler.

Using Performance Metrics. Analyzing system load indicators during bug reproduction.

Memory Dump Analysis. Using specialized tools to examine memory contents at the time of failure.

Version Comparison. Checking the behavior of functionality across different application versions or environments.
