ecu.test (local, multi-version)

Use local ecu.test files as the source of truth. Prefer RST (*_sources/*.rst.txt) when shipped (<=2025.1), otherwise use the Sphinx HTML docs (>=2025.2). Always confirm exact Python signatures in Templates\ApiClient\ApiClient.py / Templates\ApiClient\ApiClient.xml.

Base path / environment

• .env (next to this file) defines installed ecu.test roots, e.g.:
  • ECU_TEST_2024_3_HOME=C:\Program Files\ecu.test 2024.3
  • ECU_TEST_2025_4_HOME=C:\Program Files\ecu.test 2025.4
• Optional override: ECU_TEST_HOME=... (forces a single version without passing --version)

Version selection (important)

• If the user specifies a version (e.g. 2025.4), use ECU_TEST_2025_4_HOME as the install root.
• If the user does NOT specify a version:
  • use ECU_TEST_HOME if set, otherwise
  • use the latest ECU_TEST_<version>_HOME found in .env.
• If the version matters (API changed) and the user did not specify it, ask which ecu.test version to target.
