# Test TODO
This file is the current backlog for building out the MATLAB test suite.
It should reflect the repository state now, not the original plan.
## Current Status
Fast profile status:
- `run_all_tests('profile','fast')`
- latest verified result: `Passed: 59 | Failed: 0 | Incomplete: 0`
- explicit placeholder tests remaining: `70`
Mandatory workflow for every future test-writing session:
1. Read the target class implementation in `Classes/...` before writing or changing tests.
2. Read the current placeholder or existing test in `Tests/...`.
3. Replace or extend the existing test. Do not create duplicate test files.
4. Use the existing `matlab.unittest` framework and extend `IMDDTestCase`.
5. Tag new tests with `TestTags`.
6. Run the relevant test entrypoint after implementation.
7. Do not consider the task complete until the test run result is checked.
## Completed Base Tests
These are already implemented and verified in the fast profile:
- `Classes/00_signals/Signal.m` -> `Tests/00_signals/Signal_test.m`
- `Classes/00_signals/Informationsignal.m` -> `Tests/00_signals/Informationsignal_test.m`
- `Classes/00_signals/Electricalsignal.m` -> `Tests/00_signals/Electricalsignal_test.m`
- `Classes/01_transmit/PAMmapper.m` -> `Tests/01_transmit/PAMmapper_test.m`
- `Classes/01_transmit/PAMsource.m` -> `Tests/01_transmit/PAMsource_test.m`
- `Classes/01_transmit/Pulseformer.m` -> `Tests/01_transmit/Pulseformer_test.m`
- `Classes/02_optical/Fiber.m` -> `Tests/02_optical/Fiber_test.m`
- `Classes/03_receive/Photodiode.m` -> `Tests/03_receive/Photodiode_test.m`
- `Classes/03_receive/Scope.m` -> `Tests/03_receive/Scope_test.m`
- `Classes/04_DSP/TransmissionPerformance.m` -> `Tests/04_DSP/TransmissionPerformance_test.m`
- `Classes/04_DSP/Equalizer/FFE.m` -> `Tests/04_DSP/Equalizer/FFE_test.m`
- `Classes/04_DSP/Sequence Detection/MLSE.m` -> `Tests/04_DSP/Sequence Detection/MLSE_test.m`
- `Classes/04_DSP/Timing Recovery/Timing_Recovery.m` -> `Tests/04_DSP/Timing Recovery/T_04_DSP_Timing_Recovery_Timing_Recovery_test.m`
Notes:
- `Opticalsignal_test.m` still appears to be a placeholder and should be treated as unfinished.
- There are multiple `Timing_Recovery` class names in the repo, so the implemented base-class test currently uses the disambiguated file name:
`Tests/04_DSP/Timing Recovery/T_04_DSP_Timing_Recovery_Timing_Recovery_test.m`
## Next Priority Tests
Highest-value unfinished tests to implement next:
1. `Classes/00_signals/Opticalsignal.m`
`Tests/00_signals/Opticalsignal_test.m`
Focus:
- constructor metadata wiring
- `delay`
- `cspr`
- interaction with inherited signal behavior
2. `Classes/01_transmit/Signalgenerator.m`
`Tests/01_transmit/Signalgenerator_test.m`
Focus:
- constructor/config defaults
- deterministic generation path
- output type and shape
3. `Classes/02_etc/Filter.m`
`Tests/02_etc/Filter_test.m`
Focus:
- deterministic filter construction
- `process` behavior on small signals
- output rate/length invariants
4. `Classes/02_etc/Amplifier.m`
`Tests/02_etc/Amplifier_test.m`
Focus:
- gain behavior
- noise-free baseline
- output class and metadata behavior
5. `Classes/02_optical/EML.m`
`Tests/02_optical/EML_test.m`
Focus:
- deterministic modulation path
- output class and metadata
- small synthetic fixture only
6. `Classes/02_optical/Optical_Multiplex.m`
`Tests/02_optical/Optical_Multiplex_test.m`
Focus:
- combining channels
- output dimensions
- metadata handling
7. `Classes/02_optical/Optical_Demultiplex.m`
`Tests/02_optical/Optical_Demultiplex_test.m`
Focus:
- deterministic channel extraction
- output dimensions
- basic round-trip expectations with multiplexing if practical
8. `Classes/02_optical/Polarization_Controller.m`
`Tests/02_optical/Polarization_Controller_test.m`
Focus:
- deterministic transform behavior
- shape preservation
9. `Classes/02_optical/DP_Fiber.m`
`Tests/02_optical/DP_Fiber_test.m`
Focus:
- very small deterministic sanity checks only
- avoid long or GPU-heavy runs
## Next DSP Layer
After the items above, continue with these:
- `Classes/04_DSP/Coding/Duobinary.m`
`Tests/04_DSP/Coding/Duobinary_test.m`
- `Classes/04_DSP/Coding/MRDS_coding.m`
`Tests/04_DSP/Coding/MRDS_coding_test.m`
- `Classes/04_DSP/Sequence Detection/MLSE_viterbi.m`
`Tests/04_DSP/Sequence Detection/MLSE_viterbi_test.m`
- `Classes/04_DSP/Sequence Detection/MLSE_new.m`
`Tests/04_DSP/Sequence Detection/MLSE_new_test.m`
- `Classes/04_DSP/Timing Recovery/Time_Shifter.m`
`Tests/04_DSP/Timing Recovery/Time_Shifter_test.m`
- `Classes/04_DSP/Timing Recovery/Godard_Timing_Recovery.m`
`Tests/04_DSP/Timing Recovery/Godard_Timing_Recovery_test.m`
- `Classes/04_DSP/Timing Recovery/MaxVar_Timing_Recovery.m`
`Tests/04_DSP/Timing Recovery/MaxVar_Timing_Recovery_test.m`
Then move on to the remaining equalizer variants:
- `EQ.m`
- `EQ_copy.m`
- `EQ_silas*.m`
- `FFE_*`
- `ML_MLSE*.m`
- `Postfilter.m`
- `VNLE.m`
## Lower Priority Areas
Leave these for later unless a current task depends on them:
- `Classes/Warehouse_class/*`
- `Classes/DataBaseHandler/*`
- template/example classes like `class_template`
## Excluded From Automated Testing
Do not create or run automated tests for lab device classes in this repository.
Excluded area:
- `Classes/05_Lab/*`
Reason:
- the device IPs are reachable in this environment
- executing these classes can change instrument set points
- this can interfere with external or ongoing experiments
Rule for future sessions:
- do not implement `Tests/05_Lab/*`
- do not run files that communicate with lab devices
- do not add these classes back into the active TODO backlog unless explicitly requested by the user for a controlled setup
## Session Prompt Checklist
Every future agent prompt should include these requirements:
- read the class implementation first
- read the current test file second
- implement the test in the existing file
- prefer deterministic synthetic fixtures
- avoid plotting and hardware unless required
- never run or implement `05_Lab` tests in normal agent sessions
- run `run_all_tests('profile','fast')` after implementation
- report the changed files and the verification result
