Performance Tests

The performance test suite measures backend latency and throughput for computationally intensive operations. Each test uses a Jest timeout as the pass/fail threshold – if the backend does not complete the operation within the configured timeout, the test fails.

All performance tests read data files from the set_QA_performance directory. Three file formats (FITS, CASA, HDF5) are tested for each operation, enabling cross-format performance comparison.

Timeout values are configured in src/test/config.json under the performance key:

{
  "performance": {
    "openFile": 20000,
    "readFile": 10000,
    "playContour": 12000,
    "playAnimator": 300000,
    "setSpectralReqTimeout": 10000,
    "momentTimeout": 400000,
    "pvTimeout": 200000
  }
}
