# Why this change is necessary and useful
Auto-inserting namespace imports in C# is broken because the `ReplaceChunk()` call is missing an argument
[cont]: https://github.com/Valloric/YouCompleteMe/blob/master/CONTRIBUTING.md
[code]: https://github.com/Valloric/YouCompleteMe/blob/master/CODE_OF_CONDUCT.md
ReplaceChunk must have changed to require the buffer at some point
No test is included because it's a one-line change; the method is theoretically covered, so I'm not sure why the missing argument error was not caught (not familiar with these tests). Happy to add one if needed (and I can get pointed in the right direction).

[READY] Add Gitter badge and encourage users to ask questions on Gitter
This may help reduce the number of issues opened for questions or misconfigurations. This is also an alternative to the Google group for users that can't access it because of country regulations.

[READY] Enable coverage on AppVeyor
I forgot to do that when adding coverage.
Also, the `cover` folder is created at the project root, not in the `python` folder.

[READY] Move client tests to the main tests folder
This makes it possible to configure all tests at a package level by implementing the `setUpPackage` and `tearDownPackage` functions in `python/ycm/tests/__init__.py` file.

Implement ycm_quiet_messages options (See #2021)

# Why this change is necessary and useful
See issue #2021. This is a partial implementation based on the syntastic option referenced, supporting the `!` flag and filters of type `regex` and `level`. Also supports filetype specific filters using `ycm_<ft>_quiet_messages`, but I couldn't think of a great way to fall back to syntastic configs for this one.
In terms of usefulness: I've been playing with C# recently, which has a bunch of style warnings that I don't want to follow, and prefer to only have the gutter showing if there are actually errors, or warnings that I *do* want to follow.

<!-- Reviewable:end -->
We eagerly compile all the filters up front, then gather the
compiled filters into a DiagnosticFilter lazily, caching the
result to avoid garbage lists.
[READY] Move test_utils.py file to tests folder
We don't want `test_utils.py` to appear in the coverage reports. Instead of blacklisting it in `.coveragerc`, we move it to the tests folder.
This will decrease coverage.

[READY] Refactor tests using a YouCompleteMe instance
This PR adds a decorator function, similar to the `IsolatedYcmd` and `SharedYcmd` decorators from ycmd, that passes a YouCompleteMe object to tests. Its options can be customized with the parameter of the decorator. I need this to write new tests.
There is one thing annoying with this change is that Vim does not highlight a decorator function with no character between the parentheses so `@YouCompleteMeInstance()` will not be highlighted. I've contacted the maintainer of the Python syntax file about this bug. Anyway, that's not a good reason to not make this change.

[READY] Add coverage support
There should not have anything to configure on codecov website.
I updated the `run_tests` script to behave exactly like the one in ycmd repository: when passing tests as arguments, you need to specify the path from the root project, not the `python` folder. For instance:
```
./run_tests.py --skip-build -- python/ycm/tests/event_notification_test.py
```
instead of
```
./run_tests.py --skip-build -- ycm/tests/event_notification_test.py
```
This way, you can now complete the path to the test.
