By default, code coverage is disabled in `codeception.yml` configuration file, you should uncomment needed rows to be able
to collect code coverage. You can run your tests and collect coverage with the following command:
```
#collect coverage for all tests
codecept run --coverage-html --coverage-xml
#collect coverage only for unit tests
codecept run unit --coverage-html --coverage-xml
#collect coverage for unit and functional tests
codecept run functional,unit --coverage-html --coverage-xml
```
You can see code coverage output under the `tests/_output` directory.
###Remote code coverage
When you run your tests not in the same process where code coverage is collected, then you should uncomment `remote` option and its
related options, to be able to collect code coverage correctly. To setup remote code coverage you should follow [instructions](http://codeception.com/docs/11-Codecoverage)
from codeception site.
1. install `Codeception c3` remote support `composer require "codeception/c3:*"`;
2. copy `c3.php` file under your `web` directory;
3. include `c3.php` file in your `index-test.php` file before application run, so it can catch needed requests.
Configuration options that are used by remote code coverage:
- c3_url: url pointing to entry script that includes `c3.php` file, so `Codeception` will be able to produce code coverage;
- remote: whether to enable remote code coverage or not;
- remote_config: path to the `codeception.yml` configuration file, from the directory where `c3.php` file is located. This is needed
so that `Codeception` can create itself instance and collect code coverage correctly.
By default `c3_url` and `remote_config` setup correctly, you only need to copy and include `c3.php` file in your `index-test.php`
After that you should be able to collect code coverage from tests that run through `PhpBrowser` or `WebDriver` with same command
as for other tests:
```
#collect coverage from remote
codecept run acceptance --coverage-html --coverage-xml
```
