|
4 | | -The logs module provides centralized logging configuration and management for the ibind |
5 | | -library. It handles console logging, file-based logging with daily rotation, and |
6 | | -project-specific logger creation. The module supports environment-based configuration |
7 | | -and ensures proper log formatting across all components. |
8 | | -
|
9 | | -Core Functionality Tested: |
10 | | -========================== |
11 | | -
|
12 | | -1. **Project Logger Creation**: |
13 | | - - Logger naming based on file paths |
14 | | - - Default logger instantiation |
15 | | - - Logger hierarchy and namespace management |
16 | | -
|
17 | | -2. **Logging System Initialization**: |
18 | | - - Console output configuration |
19 | | - - File-based logging setup |
20 | | - - Log level and format configuration |
21 | | - - Initialization state management and idempotency |
22 | | -
|
23 | | -3. **Daily Rotating File Handler**: |
24 | | - - Automatic daily file rotation based on timestamps |
25 | | - - File path generation with date suffixes |
26 | | - - Directory creation for log files |
27 | | - - Stream management and file handle lifecycle |
28 | | -
|
29 | | -4. **Configuration Management**: |
30 | | - - Environment variable integration |
31 | | - - Default value handling |
32 | | - - Runtime configuration override |
33 | | - - Logging behavior control flags |
34 | | -
|
35 | | -Key Components: |
36 | | -=============== |
37 | | -
|
38 | | -- **project_logger()**: Creates project-specific logger instances with proper naming |
39 | | -- **ibind_logs_initialize()**: Configures the entire logging system with handlers and formatters |
40 | | -- **new_daily_rotating_file_handler()**: Sets up file-based logging with daily rotation |
41 | | -- **DailyRotatingFileHandler**: Custom logging handler for automatic daily file rotation |
42 | | -
|
43 | | -Test Coverage: |
44 | | -============== |
45 | | -
|
46 | | -This test suite provides comprehensive coverage of logging functionality including: |
47 | | -
|
48 | | -- **Logger Creation**: All project logger naming patterns and configurations |
49 | | -- **Initialization Logic**: Complete system setup with various parameter combinations |
50 | | -- **File Handling**: Daily rotation mechanics, file creation, and cleanup |
51 | | -- **Error Conditions**: Invalid configurations, file system errors, and edge cases |
52 | | -- **State Management**: Initialization tracking, global state handling, and reset scenarios |
53 | | -
|
54 | | -The tests use extensive mocking to isolate logging components while maintaining |
55 | | -realistic interaction patterns with the Python logging framework. |
56 | | -
|
57 | | -Logging Behavior: |
58 | | -================= |
59 | | -
|
60 | | -The logging system supports multiple output modes: |
61 | | -- Console-only logging for development |
62 | | -- File-only logging for production |
63 | | -- Combined console and file logging |
64 | | -- Disabled logging for testing environments |
65 | | -
|
66 | | -File logs use daily rotation with timestamps in filenames (e.g., `app__2024-01-15.txt`) |
67 | | -and automatic directory creation for log storage locations. |
68 | | -
|
69 | | -Security Considerations: |
70 | | -======================== |
71 | | -
|
72 | | -Logging systems handle potentially sensitive information and file system access. |
73 | | -Tests ensure proper handling of file permissions, directory traversal prevention, |
74 | | -and safe handling of user-provided log file paths without exposing system internals. |
