From 949a5a655bb76e28df4ed0819d50069c72f2b9c5 Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Sun, 19 Apr 2026 01:18:18 +0000 Subject: [PATCH 1/7] refactor(cli): unify error handling and user feedback across CLI commands - Create centralized CLIOutputManager class for consistent error handling - Implement unified error display with debug flag support - Add display helpers for success, warning, info, panels, and tables - Support all output formats (rich, color, table, plain, json, yaml) - Stack traces only shown when --debug flag is enabled - Add comprehensive BDD tests for error handling scenarios - Ensure consistent styling and iconography across all CLI commands --- features/cli/error_handling.feature | 88 ++++ features/sandbox_manager_concurrency.feature | 12 +

Python silently uses the package, leaving output.py permanently unreachable and at 0% coverage, which dragged the project total below the 96.5% threshold. Additionally, the json/yaml/plain format branches in `_cli_output_manager.py` had no BDD test coverage. The existing table scenarios also set the output format after calling display_table(), so the non-rich branches were never exercised. Fixes: - Delete src/cleveragents/cli/output.py (unreachable stale module) - Add 18 BDD scenarios covering json/yaml/plain format branches for all display functions: success, warning, info, error panel, success panel, table, handle_exception - Add step defs for CLIOutputManager instance method calls - Fix scenario ordering: output format set before display calls ISSUES CLOSED: #10655 --- features/cli/error_handling.feature | 93 +++++ features/steps/cli_error_handling_steps.py | 22 ++ src/cleveragents/cli/output.py | 391 --------------------- 3 files changed, 115 insertions(+), 391 deletions(-) delete mode 100644 src/cleveragents/cli/output.py diff --git a/features/cli/error_handling.feature b/features/cli/error_handling.feature index 8dd415246..c76f70178 100644 --- a/features/cli/error_handling.feature +++ b/features/cli/error_handling.feature @@ -86,3 +86,96 @@ Feature: Unified CLI Error Handling and User Feedback When a success message is displayed Then the message should be written to stdout And not to stderr + + Scenario: Display success message with JSON format + When the output format is "json" + And I display a success message "JSON success message" + Then JSON output should be displayed + And the CLI output should be valid JSON + + Scenario: Display success message with plain format + When the output format is "plain" + And I display a success message "Plain success message" + Then the message should contain a checkmark symbol + + Scenario: Display warning message with JSON format + When the output format is "json" + And I display a warning message "JSON warning message" + Then JSON output should be displayed + + Scenario: Display warning message with plain format + When the output format is "plain" + And I display a warning message "Plain warning message" + Then the message should contain a warning indicator + + Scenario: Display info message with JSON format + When the output format is "json" + And I display an info message "JSON info message" + Then JSON output should be displayed + + Scenario: Display info message with plain format + When the output format is "plain" + And I display an info message "Plain info message" + Then the message should be displayed + + Scenario: Display error panel with JSON format + When the output format is "json" + And I display an error panel with title "JSON Error" and content "Error details" + Then the error should be written to stderr + + Scenario: Display error panel with plain format + When the output format is "plain" + And I display an error panel with title "Plain Error" and content "Error details" + Then the error should be written to stderr + + Scenario: Display success panel with JSON format + When the output format is "json" + And I display a success panel with title "JSON Done" and content "All good" + Then JSON output should be displayed + + Scenario: Display success panel with plain format + When the output format is "plain" + And I display a success panel with title "Plain Done" and content "All good" + Then the message should be written to stdout + + Scenario: Display table with JSON format using correct step order + When the output format is "json" + And I display a table with columns "Name, Status" + And the table contains 2 rows of data + Then JSON output should be displayed + And the CLI output should be valid JSON + + Scenario: Display table with YAML format using correct step order + When the output format is "yaml" + And I display a table with columns "Name, Status" + And the table contains 2 rows of data + Then YAML output should be displayed + + Scenario: Display table with plain format + When the output format is "plain" + And I display a table with columns "Name, Status" + And the table contains 2 rows of data + Then a formatted table should be displayed + + Scenario: Handle exception with JSON format + When the output format is "json" + And an error is displayed + Then the error should be written to stderr + + Scenario: Handle exception with plain format + When the output format is "plain" + And an error is displayed + Then the error should be written to stderr + + Scenario: Display error with debug mode enabled before display + Given debug mode is enabled + When an error is displayed + Then the error should be written to stderr + + Scenario: Display success via manager instance method + When I display success via the manager method "Manager success" + Then the message should be written to stdout + + Scenario: Display warning via manager instance method + When I display warning via the manager method "Manager warning" + Then the message should be written to stdout diff --git a/features/steps/cli_error_handling_steps.py b/features/steps/cli_error_handling_steps.py index ea6dde885..2a684804a 100644 --- a/features/steps/cli_error_handling_steps.py +++ b/features/steps/cli_error_handling_steps.py @@ -386,3 +386,25 @@ def step_check_not_to_stderr(context: Any) -> None: output = context.stderr_capture.getvalue() #
