I know this has been asked a lot of times, but this example one test confuses me. The test example here:
Testing Routes In ASP.NET MVC
Is this a unit or integration test? On the page it specifies it is a unit test but as I understand it, an integration test are tests that uses real dependencies. So is using the GlobalApplication.RegisterRoutes considered a dependency? So is this an integration test? I'm a bit confused to the extent of what a dependency is.
This is a unit test of a particular functionality of your application: the routes that you have defined.
So is using the GlobalApplication.RegisterRoutes considered a
dependency?
No, that's the subject under test - it's what you are testing. A dependency would be something that this subject depends on in order to work. It is this dependency that can be either mocked (in a unit test) or just using the actual object (in an integration test). For example if your routes were dependent on some database lookup operation then, if you don't mock this db call, you would be writing an integration test.

I have a concept problem, I am working on a rails project & as per my knowledge both the test & spec are used for tests. Where test refers to unit testing & spec refers to integration testing. But I want to have to have full idea about those two folders & if they both refers to test then what is the major difference between them?
Rails default testing framework gives you test folder for you rails default testing framework, if you want to use RSpec testing framework, which gives you folder called 'spec' RSPEC, it is your wish to select which option, RSPEC specs are more readable, people use both ways.
Before upgrading to rails 5.1 i test my rails app via integration tests. And 70% of my rails app is automated via integration tests. Means all of application simple and complex behaviors are automated via integration tests. Off-course rails did not provided any java-script based testing.
With Arrival of Rails 5.1 they include system tests and said that every app interact with java-script and now you can test your app end to end scenarios like a real user interacting with browser. So my manager ask me to move all integration tests to system tests. Ok good! we can test our application the way our users experience it and help us test JavaScript as well.
Definitely system test can cover almost all integration tests as well. So whats the importance of integration testing now ?
Why should someone write integration test in Rails 5.1 when he can
write same test case in System test?
Thanks in advance.
I wonder the same, but from this I get the impression that system tests will replace integration testing - however, the only drawback seems to be speed and resource usage.
Unit test don't need a database.
Integration and functional tests can have different fixtures and bootstrap data.
It would be also better to split functional tests on application itself and Selenium testing robot.
So, is there any reason to keep all tests phases in one environment?
I guess that's just a convention, since:
The setup of the unit tests configure a memory database to let you use GORM methods.
Your database will be initialized only when running integration tests.
Functional tests are treated as extension and depending on your project they're not mandated (for example: plugin projects that does not rely on UI).
Nothing stops you to define custom environments and run specific commands to them. You can also create Spring Beans and configure database access according to your env, using the Environment class.
if(Environment.current == Environment.DEVELOPMENT) {
...
}
I have a good understanding of the differences between unit and intergration tests in RoR in theory. I'm using rspec and capybara to do a lot of testing on my site. What I don't understand is how do you run different tests? If I do
bundle exec rspec
it will run all of my specs in all of my spec folders (model, controller, views, integration, etc). If I want to run an integration test, is it as simple as ?
bundle exec rspec spec/integration
I know there are some differences between these types of test behind the scenes. Specifically this problem (which I also have) has me thinking about unit vs. integration: How to test for a redirect with Rspec and Capybara
What does Rails do differently when running integration tests? The solution posted in the above problem is
Checking for redirect is not supported in rspec-rails request specs,
but is supported in Rails integration tests.
So how do I make one of my tests an integration test? Is it just a matter of putting it in the right spec folder?
As I understand it rspec is designed specifically for unit testing purposes, thus you'll need to use something else for integration testing. The message seems it imply that Rails can do integration tests as well. I don't have any experience or knowledge of testing in rails alone, but I do know of the cucumber gem that is built very well for integration tests.
It has it's own domain specific language and other quirks you'll need to get used to but it should have the capability you're looking for.
So i'm going to add some tests to my project to test my ASP.NET MVC routes. Are they a unit test or an integration test?
I feel like they are a unit test, where integration tests are against db's, 3rd party services (eg. twitter, file upload, etc) .. something I would normally mock out in a unit test.
The reason I'm asking is that I was looking at Ayende's Raccon Blog and noticed they have their route tests listed as Integration Tests.
I would consider them to be unit tests. Your just testing that an endpoint reaches a particular controller action. I think that's a pretty isolated set of functionality.
