Running Tests

From the project root:

# Run all tests
python test_all.py

# Or use the test runner directly
python tests/run_tests.py

Test Runner Options

python tests/run_tests.py [options]

Options:
  --verbose, -v       Show detailed output
  --skip-lang LANG    Skip a language (c, cpp, py, ts, js, csharp, gql)
  --only-generate     Generate code only, skip tests
  --check-tools       Check tool availability only
  --clean             Clean generated and compiled files

Examples:

# Skip TypeScript tests
python tests/run_tests.py --skip-lang ts

# Only check if compilers are installed
python tests/run_tests.py --check-tools

# Generate code without running tests
python tests/run_tests.py --only-generate

Test Prerequisites

Python 3.8+ with:

pip install proto-schema-parser

C tests: GCC

# Ubuntu/Debian
sudo apt install gcc

# macOS
xcode-select --install

C++ tests: G++ with C++14 support

# Ubuntu/Debian
sudo apt install g++

# macOS
xcode-select --install

TypeScript/JavaScript tests: Node.js + npm

# Ubuntu/Debian
sudo apt install nodejs npm

# macOS
brew install node

# Then install dependencies
cd tests/ts && npm install

C# tests: .NET SDK 8.0+

# Ubuntu/Debian
sudo apt install dotnet-sdk-8.0

# macOS
brew install dotnet-sdk

Test Types

Basic Types Test

Validates serialization of primitive types (integers, floats, booleans, strings).

Array Operations Test

Validates array serialization (fixed arrays, bounded arrays, nested arrays).

Cross-Platform Compatibility

Tests interoperability between languages. Produces a compatibility matrix showing which language pairs can exchange data.

Adding a New Test

Add test to tests/test_suites.json
Create test files in tests/<lang>/
Follow test output format:
- Print [TEST START] <Language> <Test Name>
- Print [TEST END] <Language> <Test Name>: PASS or FAIL
- Exit with code 0 on success, 1 on failure

CI Integration

GitHub Actions runs tests on every push to main and every pull request. Artifacts are available for download for 5 days after each run.
