@johnny603 & @madisontran16 I'm assuming you will remove the Draft/WIP from this PR when it is ready for review. If you want me to look at it without doing that then please put in a comment. I just wanted to be clear that I'm not looking at the work at this point. If you need anything then please let me know.

Hi, the LR18 changes are now ready for review, so we’ll be removing the Draft/WIP status from the PR shortly.

This update ended up being a bit different from LR1–LR7 because LR18 validates unit conversion behavior in addition to aggregation behavior. Instead of only testing kWh → kWh responses, LR18 required seeding custom conversion fixtures and validating output in kg CO₂.

Main updates made:

• Added custom unit fixtures for Electric_Utility, kg, and kg CO₂

• Added conversion fixtures for:

  • Electric_Utility → kg CO₂
  • kg CO₂ → kg

• Updated the test to request the converted graphic unit instead of the source unit

• Added/validated the expected CSV for the converted range output

• Verified the test independently with Mocha before pushing

A few questions while reviewing:

1. Does the custom fixture setup for LR18 look consistent with the intended testing pattern for conversion-based range tests?
2. Would you prefer these CO₂ conversion fixtures to stay local to LR18, or should they be abstracted into shared test utilities similar to the kWh helpers?
3. Since LR18 introduces conversion-specific setup beyond LR1–LR7, would you recommend matching the existing naming/comments more closely with L18 in readingsLineMeterQuantity.js for consistency?

Thanks!

@johnny603 & @madisontran16 Thank you for this contribution to OED. Review and testing found it works as expected. I made one small comment within the code to consider. Also, I could not easily comment in this file so I am putting this comment here:

The directory (I think) OED is showing as a change in this PR. I'm not sure what this file is for but I think it should be removed from the PR.

As for your questions, this test does need different units/conversions than the other tests in the file. This is done in many of these test files and it is done the way you did it so your setup is fine. Specifically, the names in other tests may vary and that is fine. Also, since these tests are not as common, OED chose not to abstract the unit/conversion/meter definitions into a central. This was also done because they are often different between the tests.

Please let me know if anything is not clear or you have thoughts/questions.

I'm not sure why the eslint-disable was added. I removed it and did not see any compile issues. Given this, I think these two new lines should be removed unless you feel otherwise.

@johnny603 I see you gave this a thumbs up and resolved this comment. However, I don't see a change for this. Am I missing something? Do you think it should stay? I unresolved this comment for now.

I verified with

git diff origin/development...HEAD --stat

Should be removed now, thanks for pointing that out
