Root Cause

`--cov-context=test` was passed but the coverage config does not enable dynamic contexts, or the coverage version does not support the requested context mode.

generic

中文

传入了 `--cov-context=test`，但 coverage 配置未启用动态上下文，或 coverage 版本不支持所请求的上下文模式。

Workarounds

  1. 90% success 
    Enable dynamic contexts in coverage config:
# pyproject.toml
[tool.coverage.run]
dynamic_context = "test_function"
# then run:
pytest --cov=myapp --cov-context=test
  2. 85% success 
    Or set the env var before running:
COVERAGE_DYNAMIC_CONTEXT=test_function pytest --cov=myapp --cov-context=test

Dead Ends

Common approaches that don't work:

  1. 85% fail

    Only affects the failure threshold; contexts still not measured.

  2. 60% fail

    Hides the warning but loses per-test coverage reporting that was the goal.
