✗ from crashtest import Inspector

Demonstrates how to use the `Inspector` class to extract detailed information from a caught exception, including its type, message, and the full stack trace with code context.

import sys from crashtest import Inspector def might_fail(): a = 1 b = 0 return a / b try: might_fail() except Exception as e: inspector = Inspector(e) print(f"Exception type: {inspector.type}") print(f"Exception message: {inspector.message}") print("Stack Trace:") for frame in inspector.frames: print(f" File: {frame.file}, Line: {frame.lineno}, Function: {frame.name}") print(f" Code: {frame.line.strip() if frame.line else 'N/A'}")

Debug

Known issues

breakingCrashtest versions 0.4.0 and newer require Python 3.7 or higher. Users on Python 3.6 or older will encounter compatibility issues when upgrading.

fix

Upgrade your Python environment to 3.7 or newer, or pin `crashtest` to a version older than 0.4.0 (e.g., `<0.4.0`).

affects: >=0.4.0

gotchaVersion 0.4.0 introduced stricter type hinting. A 'too narrow type' in the `Inspector` class was fixed in 0.4.1, suggesting that `0.4.0` might have introduced new type-related errors if existing code passed unexpected types.

fix

Update to `crashtest` 0.4.1 or later to benefit from the corrected type definitions and avoid potential type-related runtime errors.

affects: 0.4.0

gotchaPrior to version 0.4.0, `crashtest` could encounter decoding errors when opening files due to the lack of explicit 'utf-8' encoding.

fix

Upgrade to `crashtest` 0.4.0 or later to ensure proper handling of file encodings.

affects: <0.4.0

gotchaIn versions prior to 0.3.1, there was an error when attempting to retrieve the line of a frame if it had no context.

fix

Upgrade to `crashtest` 0.3.1 or later to fix issues with context-less frame line retrieval.

affects: <0.3.1

breakingThe `Inspector` class was moved from being directly available under the `crashtest` package to `crashtest.inspector` in version 0.4.0. Attempts to import it directly via `from crashtest import Inspector` will result in an `ImportError` in versions 0.4.0 and newer.

fix

Update import statements from `from crashtest import Inspector` to `from crashtest.inspector import Inspector` to correctly import the class.

affects: >=0.4.0
