Basic Testing for Discojs #697
base: develop
Are you sure you want to change the base?
Conversation
… equals are useless boilerplate for a short function (a variable should only be declared if it is used at least twice, except in very few exceptions that need excplicit justification

thanks for the contribution! some stuff to iron out, I hope that the remarks will help.
you didn't explicitly ask for a review but your PR wasn't in draft so I though I'll take a look
also, the CI failed with some lint error, you might want to look into it.
btw, the branch name is not following our guidelines, its format is $issue-$description-in-very-few-workd-$username

yeah, no need to test for that, aggregator would need to be redone at some point and avoiding to have any reference to the task or the model will be the first thing

thank you. It's the first time I work on GitHub with PRs that are not made by cloning for a PR. Should I make a new branch from this branch for the PR?

I'm not sure that I follow you: this is already a PR, you can added changes by pushing new commits to the same branch ("test_components") and it'll show up here.

hum, discojs is still using mocha/chai but if we want new features not present in theses, we will rather move to vitest (already used in the webapp & discojs-node) which provides mocking, parallel testing, good typescript support, …
that said, after the other comments, I don't think you'll even need "ts-mockito" anymore

that's not needed (and is being shown as very red in my git diff
).
we don't enforce a formatter yet but I'm all for slowly moving to prettier (that is, when you add changes, prettify it around, but not the whole file if you only changed a line). I'm hopeful that the transition will be smoother this way.

double negation are hard on my brain. it also feels as a duplicate of the previous one. you can merge the two and check that it didn't advance with only two clients contributions but does with three.

reads more nicely. also, you can keep the test itself smaller by not having three clients but only one. less code == faster to understand => less bug.

the root package.json is hardly ever changed, especially for dev deps used in a single package. I use it for syncing version of dependencies that are needed across many packages.
please modify discojs/package.json if you want to add a package for discojs. (which you probably don't need as stated previously)

this is a bench test, you can simplify it by using a Set(…).forEach((op) => …)
while at it, should it fail? an addition without value can be zero, a multiplication can be one; why is this test needed?
