Set path for approved tests in code rather than config file

[nlohmann]

I have a test suite with over 64k tests from a single function in pytest. All approved tests are written to the same directory, which gets a bit crowded. I would like to create subdirectories to distribute the files.

Is there a way to set the directory of the approved tests in code? So far, I only found approvaltests_config.json, but this sets it for the whole test suite which is not sufficient for me.

I think this can be acheived with specifying a namer, example:

ApprovalTests.Python/approvaltests/commandline_interface.py

Line 27 in 71778b0

verify(received, namer=CliNamer(test_id=test_id))

the verify call can be configured with:

verify(result, options=Options().with_namer(namer))

Maybe a good start is to extend NamerBase

Thanks, I made it work!

Cool, can you share your solution?

Sure:

# parameter is a string passed by pytest
# test_suite is a string passed by each test suite to create individual folders

# we want JSON output
options = approvaltests.Options({'extension_with_dot': '.json'})

# pass the parameter and set the output directory
namer = approvaltests.ScenarioNamer(approvaltests.get_default_namer(), parameter)
namer.base_namer.get_file_name()
namer.base_namer.config = {'subdirectory': os.path.join('approved_files', test_suite)}
namer.base_namer.config_loaded = True
options = options.with_namer(namer)

# json_object is built by the test and is a dict

# actual approval and passing our options
approvaltests.verify(data=json_object, encoding='utf-8', newline="\n", options=options)
