| General info |
TestNG is a testing framework for the Java programming language inspired by JUnit and NUnit TestNG is similar to JUnit and NUnit but with newer functionalities such as: annotations, test that your code is multithread safe, flexible test configuration, support for data-driven testing (with @DataProvider), support for parameters, powerful execution model (no more TestSuite) and more... It's also designed to cover all categories of tests unit, functional, end-to-end, intergration... etc |
Domain Specific Language (DSL) testing solution for Ruby code It focuses on empowering Test Driven Development (TDD). RSpec contains multiple smaller libraries, which may be independently used with other testing frameworks. |
|
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality. |
No
|
Yes Yes, but it differs from more traiditional xUnit solutions. Its tests are written in a "Tests as Specification" manner. This means that the terminology used in RSpec is adjusted to a language more fitting for specification. |
|
Client-side
Allows testing code execution on the client, such as a web browser |
Yes The scope of testing with testNg is wide and you can test various front-end functionalities and behaviours with it |
Yes RSpec is used to primarily test the behaviour of applications or individual components so it can test front-end behaviour as well - you can use capybara gem with RSpec for that. |
|
Server-side
Allows testing the bahovior of a server-side code |
Yes You can test server-side functionalities and behaviours with TestNg |
Yes You can test server-side behaviour with Rspec |
|
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test |
Yes Fixtures are inbuilt into testNG, these are the annotations which are: @BeforeSuite, @AfterSuite, @BeforeTest, @AfterTest, @BeforeGroups, @AfterGroups, @BeforeClass, @AfterClass, @BeforeMethod, @AfterMethod |
Yes RSpec does contain fixture methods |
|
Group fixtures
Allows defining a fixed, specific states of data for a group of tests (group-fixtures). This ensures specific environment for a given group of tests. |
Yes You can use various fixtures to setup environments for group tests |
Yes Group fixture methods are supported |
|
Generators
Supports data generators for tests. Data generators generate input data for test. The test is then run for each input data produced in this way. |
N/A
|
Yes RSpec contains generators for example intergration_'test_name' which will save a spec inside the spec/requests folder |

Mocks
Mocks are objects that simulate the behavior of real objects. Using mocks allows testing some part of the code in isolation (with other parts mocked when needed) |
Yes By Use of an external library like mockit which intergrates well with testNG |
Yes Available through rspec-mocks gem. |
|
Grouping
Allows organizing tests in groups |
Yes Multiple test cases can be grouped more easily by converting them into testng.xml file, in which you can make priorities which test case should be executed first |
Yes Allows declaring example groups and contexts. |
