# Unit and Functional Tests
|
|
|
|
A unit test is about testing a single function/method in isolation with all of its possible outputs.
|
|
|
|
A functional test is about testing a single functionality, which can span multiple methods and a controller.
|
|
|
|
Other common terms in Rails are "model tests," "controller tests," and others.
|
|
|
|
You can find model tests in `spec/models`, controller tests in `spec/controllers` and additional functional tests in various directories within the `spec` directory.
|
|
|
|
You can run all models tests, for example, with:
|
|
|
|
```shell
|
|
bundle exec rspec spec/models
|
|
```
|
|
|
|
To run an individual file you can use, for example:
|
|
|
|
```shell
|
|
bundle exec rspec spec/models/user_spec.rb
|
|
```
|
|
|
|
To run a specific test case you can use, for example:
|
|
|
|
```shell
|
|
bundle exec rspec spec/models/user_spec.rb:10
|
|
```
|
|
|
|
where `10` is the line number of the test case that you want to execute.
