Sanity tests

Sanity tests are a great tool for debugging the blockchain state. Running them automatically can allow to catch a problem early before it becomes too difficult to manage.

To run sanity tests locally on the gdev, use

WS_RPC_ENDPOINT=wss://gdev.trentesaux.fr:443/ws cargo sanity-gdev

(you can use a custom rpc endpoint)

Example use : https://git.duniter.org/nodes/rust/duniter-v2s/-/issues/85

We should list the coverage we want for sanity tests and implement them early in the migration process.

We have to check the consistency of the data of all the storage items of all the pallets, for the moment we check very few, if someone wants to list them, just look at all the occurrences of ::storage in our codebase and in substrate pallets that we use.

The sanity tests are played every 24 hours by a scheduled pipeline on gitlab against my RPC node, and I get an email when they fails.

You might want to:

  • connect your node to ĞDev5
  • change the default url of the sanity tests to one of the ĞDev5 nodes

Otherwise you will keep receiving emails for outdated data (example sanity_tests (#76794) · Jobs · nodes / rust / Duniter v2S · GitLab)

After batch transfer to addresses with less than existential deposit (@poka’s ĞDev5 did not include the genesis fix) I ran the sanity tests on my node, we still have one error:

I think it’s a bug, I will fix it until the end of December.

This was an easy bug (copy-paste typo), but I also have to complete the tests. See MR !146 (wip).

@tuxmain do you see a reason not to use tests with #[test] in the sanity tests and instead implement a strange .assert() method?


I added a sanity test (btw it’s the worst code I’ve seen from elois, he must have been in a hurry when he wrote this).

Assertions are for end-user runtime checks on potentially dynamic input (or for enabling compiler optimisations but not in this case), while cargo tests are for testing the code’s behaviour on determined input.

It makes sense to check blockchain state using assertions. The custom assert it just more convenient than the standard panicking assert as it enables seeing all the errors directly.

Ok, but apart from the intended use of cargo tests, it could be more convenient to use a proper test suite instead of custom one.

New test gives:

Two addresses have multiple identities. This should never happen. @ManUtopiK is the other one.


This problem was already present at the genesis:

so we have to find out whether it’s a problem of genesis parsing or genesis produced by @poka’s june-migrator.

[edit] I do not see any problem in https://g1-migrator.axiom-team.fr/genesis/gdev.json data. It could have been introduced later (for example a copy-paste error when adding session keys), or less likely a parsing issue. We should look in raw chainspecs for that, but that’s not convenient :confused:

About Manutopik, this is my fault, he was present 2 times in smiths array, removed just after here.

I thought it was ok if genesis parsing says all good, that it took only once. But I don’t know about your idtyIndex, this human error was only about ManutopiK as I know. We should check it in rawspec but I don’t know how to interpret this format yet…

We should probably add theses kind of test in genesis parsing, no ?

Yes, and also run the live tests just after starting the blockchain.

Yes, I plan to completely rewrite the genesis parsing for gtest (and keep it as it is for gdev). I’ll detail it in another post.
