Unit Test - testing an individual unit, such as a method (function) in a class, with all dependencies mocked up. 

Functional Test - AKA Integration Test, testing a slice of functionality in a system. This will test many methods and may interact with dependencies like Databases or Web Services.

blocks|key|1263359|text|“功能测试”并不意味着您正在测试代码中的函数(方法)。这通常意味着您正在测试系统功能--当我在命令行运行foo+file.txt时，file.txt中的行可能会颠倒过来。相比之下，单个单元测试通常涵盖单个方法的单个用例--+length("hello")应返回5，length("hi")应返回2。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1263360|另请参见IBM's+take+on+the+line+between+unit+testing+and+functional+testing。|1263361|entityMap|0|LINK|mutability|MUTABLE|url|http://www.ibm.com/developerworks/library/j-test.html#h4^0|1G|C|1U|8|34|F|3O|C|0|4|1U|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]|$9|S|A|T|B|C]|$9|U|A|V|B|C]|$9|W|A|X|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Y|8|@]|D|@$9|Z|A|10|1|11]]|E|$]]|$1|H|3|-4|5|6|7|12|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

"Functional test" does not mean you are testing a function (method) in your code. It means, generally, that you are testing system functionality -- when I run <code>foo file.txt</code> at the command line, the lines in <code>file.txt</code> become reversed, perhaps. In contrast, a single unit test generally covers a single case of a single method -- <code>length("hello")</code> should return 5, and <code>length("hi")</code> should return 2.

blocks|key|1048797|text|我的想法是这样的:单元测试确定代码执行您希望代码执行的操作(例如，您想要添加参数a和b，实际上是将它们相加，而不是减去它们)，功能测试确定所有代码协同工作以获得正确的结果，因此您希望代码执行的操作实际上会在系统中获得正确的结果。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1048798|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The way I think of it is like this: A unit test establishes that the code does what you intended the code to do (e.g. you wanted to add parameter a and b, you in fact add them, and don't subtract them), functional tests test that all of the code works together to get a correct result, so that what you intended the code to do in fact gets the right result in the system.

blocks|key|1263513|text|在Rails中，单元文件夹用来保存模型的测试，功能文件夹用来保存控制器的测试，集成文件夹用来保存涉及任意数量的控制器交互的测试。Fixtures是一种组织测试数据的方法；它们驻留在fixtures文件夹中。test_helper.rb文件保存测试的默认配置。你可以访问this。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1263514|entityMap|0|LINK|mutability|MUTABLE|url|http://guides.rubyonrails.org/testing.html^0|3Q|4|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

In Rails, the unit folder is meant to hold tests for your models, the functional folder is meant to hold tests for your controllers, and the integration folder is meant to hold tests that involve any number of controllers interacting. Fixtures are a way of organizing test data; they reside in the fixtures folder. The test_helper.rb file holds the default configuration for your tests.
