This commit updates GEMINI.md to include instructions for building and
running Nexus tests. Nexus is a test framework that enables faster and
more scalable network simulations within a single process.
The updated documentation provides:
- A brief overview of the Nexus test framework.
- The command to build Nexus tests using 'tests/nexus/build.sh'.
- Commands to run all Nexus tests or a specific test using
'tests/nexus/run_nexus_tests.sh'.
- A reference to 'tests/nexus/README.md' for further details.
This commit updates 'tests/nexus/README.md' to provide detailed
instructions on how to build and run the Nexus tests, including
the recently added automated testing and packet verification
scripts.
Changes:
- Added instructions for building TREL tests using 'build.sh trel'.
- Added a section on automated testing and packet verification
using the 'run_nexus_tests.sh' script.
- Explained how to run individual C++ tests and Python verification
scripts manually.
- Clarified the usage of topology names and JSON output filenames
as arguments for Nexus C++ tests.
This commit introduces a new test framework named Nexus. The
framework includes the Nexus platform implementation that emulates
platform behavior, allowing multiple nodes running the OpenThread
core stack to be simulated and interact with each other within the
same process.
Unlike the simulation platform, where nodes run in separate processes
and interact via POSIX sockets, Nexus nodes are simulated within a
single process. Nexus tests can interact directly with the C++ or C
OT core APIs, providing more control than the simulation platform's
CLI-based interactions. The flow of time in Nexus tests is directly
controlled by the test itself, allowing for quick time interval
advancement.
This model allows for faster and more scalable simulations, enabling
quick simulation of larger networks for longer durations.
This commit introduces the basic platform implementation, including:
- `nexus_alarm`, `nexus_radio`, and `nexus_settings` modules.
- Logging support, allowing logs to be distinguished per emulated
node.
