CONTRIBUTING to eslint-plugin-jsdoc
Testing changes locally
You might try a TDD approach and add tests within the test directory,
to try different configs, you may find it easier to try out changes in
a separate local directory.
You can run npm link for this purpose,
pointing from your project to this project. For example, while in your project
root and with eslint-plugin-jsdoc as a sibling, run:
npm link ../eslint-plugin-jsdoc
Building the project
After running npm install to get the latest dependencies and devDependencies,
you can run the following command to update the dist files, with dist/index.js
being the main entrance point from package.json:
npm run build
Coding standards
The project follows ESLint rules from canonical
and testing follows its subconfig, canonical/mocha.
Testing
Tests are expected. Each rule file should be in CamelCase (despite the rule names themselves being hyphenated) and should be added within test/assertions and then imported/required by
test/rules/index.js.
Each rule file should be an ESM default export of an object which has valid and invalid array properties containing the tests. Tests of each type should be provided.
parserOptions will be ecmaVersion: 6 by default, but tests can override parserOptions
with their own.
See ESLint's RuleTester
for more on the allowable properties (e.g., code, errors (for invalid rules),
options, settings, etc.).
Note that besides npm test, there is npm run test-cov which shows more
detailed information on coverage. Coverage should be maintained at 100%, and
if there are a few guards in place for future use, the code block in question
can be ignored by being preceded by /* istanbul ignore next */ (including
for warnings where the block is never passed over (i.e., the block is always
entered)). If you want to test without coverage at all, you can use
npm run test-no-cov. To only test rules rather than other files, you
can use npm run test-index.
To test specific rules, you can supply a comma-separated list with the --rule
flag passed to test-index, e.g., for check-examples and require-example:
npm run --rule=check-examples,require-example test-index.
You can further limit this by providing --invalid and/or --valid flags
with a comma-separated list of 0-based indexes that you wish to include (also
accepts negative offsets from the end, e.g., -1 for the last item). For
example, to check the first and third invalid tests of check-examples
alon with the second valid test, you can run:
npm run --rule=check-examples --invalid=0,2 --valid=1 test-index.
Requirements for PRs
PRs should be mergeable, rebasing
first against the latest master.
The number of commits will ideally be limited in number, unless extra commits can better show a progression of features.
Commit messages should be worded clearly and the reason for any PR made clear by linking to an issue or giving a full description of what it achieves.
Merging
We use semantic-release
for preparing releases, so the commit messages (or at least the merge that
brings them into master) must follow the
AngularJS commit guidelines with a special format such as feat: describe new feature
in order for the releasing to occur and for the described items to be added
to the release notes.
