在分子中使用testinfra作为验证器时，如何调试测试

Question

当使用分子工具测试ansible角色并使用testinfra(pytest)验证结果时，我无法打印或调试某些输出或ansible变量。

============================= test session starts ==============================

tests/test_default.py::test_Ansible_variable[ansible://instance] PASSED  [100%]

=========================== 1 passed in 3.29 seconds ===========================

有没有办法做到这一点？

在molecule.yml文件中的testinfra验证器组件下，启用“s”选项。例如：

  name: galaxy
driver:
  name: docker
