Test that warning messages are logged only once when using the assertLogs context manager.
|
|
|
|
This unit test checks the behavior of the logging system when warning messages are issued
|
|
multiple times within the same context. It uses the assertLogs context manager to capture
|
|
log messages at the INFO level and verifies that warning messages are logged only once.
|
|
|
|
Example:
|
|
To use this test case, call it using a test runner like unittest:
|
|
```
|
|
python -m unittest your_test_module.TestLogging.test_warn_once
|
|
```
