  • 04-Nov-2024, ELF, KAB, and others: notes on existing integtests

"integtests" are intended to be automated integration and/or system tests that make use of the "pytest" framework to validate the operation of the DAQ system in various scenarios.

Here is a sample command for invoking a test (feel free to keep or drop the options in brackets, as you prefer):

pytest -s minimal_system_quick_test.py [--nanorc-option log-level debug]  # this nanorc option is still useful even when using drunc

The "-k" pytest option can be used ro selectively run a subset of the configurations in one of our integtest files. For example:

pytest -s -k TPG 3ru_3df_multirun_test.py

For reference, here are the ideas behind the tests that currently exist in this repository:

  • minimal_system_quick_test.py - verify that a small emulator system works and successfully writes data in a short run

  • readout_type_scan.py - verify that we can write different types of data (WIBEth, PDS, TPG, etc.)

  • 3ru_3df_multirun_test.py - verify that a system with multiple RUs and multiple DF Apps works as expected, including TPG

  • small_footprint_quick_test.py - like minimal_system_quick_test, but using even fewer computer resources

  • fake_data_producer_test.py - verify that the FakeDataProdModule DAQModule works as expected

  • long_window_readout_test.py - verify that readout windows that require TriggerRecords to be split into multiple sequences works as expected

  • 3ru_1df_multirun_test.py - verify that we don't get empty fragments at end run

  • this test is also useful in looking into high-CPU-usage scenarios because it uses 3 data producers in 3 RUs

  • tpstream_writing_test.py - verify that TPSets are written to the TP-stream file(s)

  • example_system_test.py - verify that the example configurations in example-configs.data.xml work as expected
