For Developers of TEN framework

The TEN framework includes three types of test suites:

• Unit Tests

• Smoke Tests

• Integration Tests

The TEN framework uses gtest as the testing framework for unit tests and smoke tests, and pytest as the testing framework for integration tests.

Unit Tests

The source directory for unit tests is tests/ten_runtime/unit. If you need to add new unit test cases, please place them in the tests/ten_runtime/unit directory.

For C++ projects, after successful compilation, you can navigate to the output directory (e.g., out/linux/x64/tests/standalone/, depending on the target OS and CPU) and execute the following command:

./ten_runtime_unit_test

Smoke Tests

The source directory for smoke tests is tests/ten_runtime/smoke. If you need to add new smoke test cases, please place them in the tests/ten_runtime/smoke directory.

Navigate to the output directory (e.g., out/linux/x64/tests/standalone, depending on the target OS and CPU) and execute the following command:

./ten_runtime_smoke_test

Loop Testing

You can perform multiple rounds of testing using the following commands.

To run only unit tests:

failed=0; for i in {1..100}; do if [ ${failed} != 0 ]; then echo "error occurred:" ${failed}; break; fi; ./ten_runtime_unit_test; failed=$?; done;

To run only smoke tests:

failed=0; for i in {1..100}; do if [ ${failed} != 0 ]; then echo "error occurred:" ${failed}; break; fi; ./ten_runtime_smoke_test; failed=$?; done;

To run both unit tests and smoke tests:

failed=0; for i in {1..100}; do if [ ${failed} != 0 ]; then echo "error occurred:" ${failed}; break; fi; ./ten_runtime_unit_test; failed=$?; if [ ${failed} != 0 ]; then echo "error occurred:" ${failed}; break; fi; ./ten_runtime_smoke_test; failed=$?; done;

Integration Tests

Integration tests are black-box tests for the TEN framework. The source directory for integration tests is tests/ten_runtime/integration. These tests are used to validate real-world execution scenarios.

The file structure for integration tests is as follows:

tests/ten_runtime/integration/
  ├── test_1/
  │    ├── test_case.py
  │    └── ...
  ├── test_2/
  │    ├── test_case.py
  │    └── ...
  └── ...

To execute the integration tests, use the following command:

cd path/to/out/
pytest tests/ten_runtime/integration/

Testing Tricks

Linux

On Linux, you can use the following technique to slow down the execution of TEN, which can help in triggering timing-related bugs.

sudo apt install util-linux
cpulimit -f -l 50 -- taskset 0x3 ...

• taskset 0x1: Use only 1 CPU core to run the program.

• taskset 0x3: Use only 2 CPU cores to run the program.
