Stratify OS (SOS) Test Suite

The Stratify OS Test Suite includes Stratify OS applications that test each aspect of the Stratify API using three types of tests:

• API: Tests to see that the functions perform as described in the documentation
• Performance: Executes a deterministic test that can be compared across platforms and between API versions to monitor improvements
• Stress: Executes random use cases over a large number of iterations in order to find bugs in Stratify OS or the Stratify API

The Tests

Stratify API Tests

The API tests are broken down by namespace (one application for each namespace). For example, api-sys-test tests the sys namespace.

Additional Tests

Posix Test

This directly tests the POSIX implementation on Stratify OS.

Math Test

This tests the underlying math operations which allows a comparison between using libgcc or clang's compiler RT implementation of math functions.

The Results

The output is in JSON format that can be easily parsed.

Building and Running the Tests

All tests can be built for the Stratify OS embedded applications using the following commands (api-inet-test as an example):

cd api-inet-test
mkdir cmake_arm
cd cmake_arm
cmake ..
cmake --build . --target all -- -j 8

The test can be run using Stratify Link on a target board running Stratify OS.

Some tests support building for the Link target. The Link target allows you to run the tests on a desktop computer. The api-inet-test supports the link target as well. From within the sostest repository, you can build using the following commands:

cd api-inet-test
mkdir cmake_link
cd cmake_link
cmake ..
cmake --build . --target all -- -j 8

The output can be run using the following command (in the cmake_link directory).

../build_release_link/api-inet-test

Building on Windows

When building on Windows, use the PowerShell program rather than the command prompt. The cmake .. line above needs to be cmake -G "MinGW Makefiles" ...
