Pytest ยังไม่หาการทดสอบเมื่อ structlog คือปรับแต่ง

Question 1

ฉันมีปลั๊กอินสำหรับไพธอนโครงการที่ฉันใช้ pytest สำหรับหน่วยของฉันการทดสอบ.

ปกติแล้วถ้าผมทำตามคำสั่งจากของฉันทดสอบโฟลเดอร์:

pytest --collect-only

ฉันจะไปเอาของฉันการทดสอบ:

...
40 tests collected
...

ตอนนี้เรามาพูดว่าฉันกำหนดห้องเรียนใหม่ structlogconf.py (จากเรื่องนี้ ตัวอย่าง)

import logging
import logging.config
import structlog


def configure() -> None:
    timestamper = structlog.processors.TimeStamper(fmt="%Y-%m-%d %H:%M:%S")
    pre_chain = [
        # Add the log level and a timestamp to the event_dict if the log entry
        # is not from structlog.
        structlog.stdlib.add_log_level,
        timestamper,
    ]

    logging.config.dictConfig(
        {
            "version": 1,
            "disable_existing_loggers": False,
            "formatters": {
                "plain": {
                    "()": structlog.stdlib.ProcessorFormatter,
                    "processor": structlog.dev.ConsoleRenderer(colors=False),
                    "foreign_pre_chain": pre_chain,
                },
                "colored": {
                    "()": structlog.stdlib.ProcessorFormatter,
                    "processor": structlog.dev.ConsoleRenderer(colors=True),
                    "foreign_pre_chain": pre_chain,
                },
            },
            "handlers": {
                "default": {
                    "level": "DEBUG",
                    "class": "logging.StreamHandler",
                    "formatter": "colored",
                },
                "file": {
                    "level": "DEBUG",
                    "class": "logging.handlers.WatchedFileHandler",
                    "filename": "test.log",
                    "formatter": "plain",
                },
            },
            "loggers": {
                "": {
                    "handlers": ["default", "file"],
                    "level": "DEBUG",
                    "propagate": True,
                },
            },
        }
    )
    structlog.configure(
        processors=[
            structlog.stdlib.add_log_level,
            structlog.stdlib.PositionalArgumentsFormatter(),
            timestamper,
            structlog.processors.StackInfoRenderer(),
            structlog.processors.format_exc_info,
            structlog.stdlib.ProcessorFormatter.wrap_for_formatter,
        ],
        logger_factory=structlog.stdlib.LoggerFactory(),
        wrapper_class=structlog.stdlib.BoundLogger,
        cache_logger_on_first_use=True,
    )

ถ้าตอนนี้ผมวิ่งไปที่ pytest รับคำสั่งอีกครั้ง pytest จะไม่ฟื้นคืนทุกการทดสอบห้องซึ่งนำเข้าตรงหรือ indirectly ร ปรับแต่ง() จากฟังก์ชัน structlogconf.py. ดังนั้นฉันตอนนี้เอา someting อย่าง:

...
5 tests collected
...

มีใครอยู่ซึ่งก็รู้ว่าต้องการใช้ struct ปูมบันทึก conf อยู่ในทางนั้นจะไม่มีผลกับฉัน pytest การทดสอบ dicscovery?

FYI:นี่คือ stacktrace ตอนที่วิ่งที่เก็บอยู่ใน problematic สถานการณ์:

... 
my remaining 5 tests which does not indirectly import my configure() function are showing here
