py.test：在命令行中指定python_files

Question

I want to set the argument python_files in pytest. The documentation says you need to put it in a configuration file, but I want to include it in the command line as part of the call to py.test , so I won't have to add that configuration file. Is that possible?

Answer 1

It is not possible with pytest out of the box as it is now (2.8). The pytest parser knows about command-line options ( addoption/getoption ) and config file values ( addini/getini ) but they are quite separate.

It is probably possible to write a plugin to add python_files (or any other ini value) as a command-line option. But just adding a conftest file is certainly the simpler option.
