## Testing
Having a good suite of tests is very important to the stability and
-maintainability of any code base. The tests in the Rails port code are
+maintainability of any code base. The tests in the `openstreetmap-website` code are
by no means complete, but they are extensive, and must continue to be
so with any new functionality which is written. Tests are also useful
in giving others confidence in the code you've written, and can
greatly speed up the process of merging in new code.
-When hacking, you should:
+When contributing, you should:
* Write new tests to cover the new functionality you've added.
* Where appropriate, modify existing tests to reflect new or changed
You can run the existing test suite with:
```
-bundle exec rake test
+bundle exec rails test:all
```
You can view test coverage statistics by browsing the `coverage` directory.
-The tests are automatically run on Pull Requests and other commits with the
-results shown on [Travis CI](https://travis-ci.org/openstreetmap/openstreetmap-website).
+The tests are automatically run on Pull Requests and other commits via github
+actions. The results shown are within the PR display on github.

right thing.

and why it should be the way it is.

When writing commit messages please try and stick to the same style as
other commits, namely:
For simple commits the one line summary is often enough and the body
of the commit message can be left out.
-## Sending the patches
+## Pull Requests
If you have forked on GitHub then the best way to submit your patches is to
push your changes back to GitHub and then send a "pull request" on GitHub.
-Otherwise you should either push your changes to a publicly visible git repository
-and send the details to the [rails-dev](https://lists.openstreetmap.org/listinfo/rails-dev)
-list or generate patches with `git format-patch` and send them to the
-[rails-dev](https://lists.openstreetmap.org/listinfo/rails-dev) list.
+If your pull request is small, for example one or two commits each containing
+only a few lines of code, then it is easy for the maintainers to review.
+
+If you are creating a larger pull request, then please help the maintainers
+with making the reviews as straightforward as possible:
+
+* The smaller the PR, the easier it is to review. In particular if a PR is too
+ large to review in one sitting, or if changes are requested, then the
+ maintainer needs to repeatedly re-read code that has already been considered.
+* The commit history is important. This is a large codebase, developed over many
+ years by many developers. We frequently need to read the commit history (e.g.
+ using `git blame`) to figure out what is going on. So small, understandable,
+ and relevant commits are important for other developers looking back at your
+ work in future.
+
+If you are creating a large pull request then please:
+
+* Consider splitting your pull request into multiple PRs. If part of your work
+ can be considered standalone, or is a foundation for the rest of your work,
+ please submit it separately first.
+* Avoid including "fixup" commits. If you have added a fixup commit (for example
+ to fix a rubocop warning, or because you changed your own new code) please
+ combine the fixup commit into the commit that introduced the problem.
+ `git rebase -i` is very useful for this.
+* Avoid including "merge" commits. If your PR can no longer be merged cleanly
+ (for example, an unrelated change to Gemfile.lock on master now conflicts with
+ your PR) then please rebase your PR onto the latest master. This allows you to
+ fix the conflicts, while keeping the PR a straightforward list of commits. If
+ there are no conflicts, then there is no need to rebase anything.
