# This is work in progress, testing workflow in local/CI is gradually being transferred to tox

# Usage instructions:

# `tox` will run all "envlist" tests sequentially, `tox --parallel` same tests in parallel (much faster).
# "othertests" are advisable to run sequentially as parallel running can lead to segmentation faults and weird errors. Hence,
# the reason for their separation. `tox -m othertests` will run these tests sequentially.

# Run specific selection of tests with `tox -e pretest,<list-of-tests>,posttest,kill-servers` e.g., `tox -e pretest,test-api,test-launcher,posttest,kill-servers`
# `--parallel` flag can also be passed when running specific selections.

# For packaging, build wheels for specific platform with `tox -e build-wheel -- <platform_name>`.
# If `tox -e build-wheel` is run without passing a platform, tox will automatically build the ffl wheels based on the operating system
# on which it is executing: windows -> "win_amd64", linux -> "manylinux_2_17_x86_64", mac -> "any"

# For html documentation generation, run `tox -e doc-html`. To clean previously existing documentation before generating
# a new one, run `tox -e doc-clean,doc-html`

# Current tox configuration can automatically detect DPF server installation in these cases:
# - Unified install
# - if ANSYS_DPF_PATH is set and points to a valid DPF server installation
# Which means invoking tox with previous commands necessitate having a server available via above methods

# Understandably for development purposes, more flexibility may be desired and there are various ways of invoking tox to achieve desired effects.
# For example, to use a standalone dpf server (present in ansys_dpf_server_win_v2025.1.pre0/ directory) in editable mode in each tox environment,
# you can do something like `tox -m othertests -x testenv.deps+="-e ansys_dpf_server_win_v2025.1.pre0"`.
# The tox documentation should be consulted for a quick overview of different CLI flags that can be used to customize invocation.
