Testing

Unit Tests

cargo test --workspace

Unit tests are embedded in source modules (mod tests { }).

Integration Tests

The workspace includes viva-fake-gige, an in-process GigE Vision camera simulator. All integration tests run automatically with cargo test – no external tools or hardware required.

# Run all tests (unit + integration)
cargo test --workspace

# Run integration tests specifically
cargo test -p viva-genicam --test fake_camera

# Run viva-service end-to-end tests (Zenoh bridge)
cargo test -p viva-service --test fake_camera_e2e

The fake camera supports:

• GVCP discovery on UDP (loopback)
• GenCP register read/write with an embedded GenApi XML
• GVSP streaming with synthetic image frames and real timestamps
• Chunk data (timestamp, exposure time) when ChunkModeActive is enabled
• Timestamp features (GevTimestampTickFrequency, GevTimestampValue, TimestampLatch)

Demo

Run the self-contained demo to see the full workflow without hardware:

cargo run -p viva-genicam --example demo_fake_camera

This starts a fake camera, discovers it, reads/writes features, and streams frames – all on localhost with zero setup.

Manual / Interactive Testing

For interactive testing or E2E testing with genicam-studio, start the fake camera as a standalone server:

# Stays alive until Ctrl+C
cargo run -p viva-fake-gige
cargo run -p viva-fake-gige -- --width 512 --height 512 --fps 15

Then use viva-camctl or viva-service to interact with it. See the Testing without hardware tutorial for details.
