Unit Testing

General info

go test is an inbuilt tool/command for conducting automated tests in Golang while testing is the inbuilt testing library

Testing is the package that is shipped with go and combines with the go test command to provide a minimal but complete testing experience

Unittest2 is a newer version on the inbuilt unit testing framework unittest

To use o use unittest2 instead of unittest, simply replace 'import unittest' with 'import unittest2'. It has many new features such as: - addCleanups for better resource management; -many new assert methods; - assertRaises as context manager, with access to the exception afterwards; - test discovery and new command line options (including failfast and better handling of ctrl-C during test runs); - class and module level fixtures: setUpClass, tearDownClass, setUpModule, tearDownModule; -test skipping and expected failures and many more improvements on the API and bug fixes
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

No

However there are Plugins such as https://github.com/tebeka/go2xunitto convert the output of Go testing library into xUnit format

Yes

unittest2 is a newer version of unittest which is an xUnit style framework for Python.
Client-side
Allows testing code execution on the client, such as a web browser

Yes

Yes it can be used effectively for front-end testing

Yes

Front-end functionality and behaviour can be tested by unittest2. function by function
Server-side
Allows testing the bahovior of a server-side code

Yes

Yes, it is used by developers for end-to-end testing so the back-end can be tested easily as well

Yes

We can write tests with unittest2 to test each function for server-side behaviour
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Yes it's straightforward in that first when you run 'go test' for packages in the scope the test will be executed with its working directory set to the source directory of the package being tested. Second the 'go test' tool will ignore any directory in your $GOPATH that starts with the word 'testdata' , starts with a period or an underscore

Yes

By use of the 'setUp()' function which is called to prepare the test fixture
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

Group fixtures can be done following a similar procedure as a single fixture

Yes

unittest2 allows you to group your initialization code buy use of the 'setUp()' function and clean up code with a 'tearDown()' function
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.

Yes

They are available by importing a package called 'gotests' (https://github.com/cweill/gotests)

Yes

unittest2 contains generator methods in the module 'unittest.TestCase'

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 a third party library GoMock which intergrates well with the testing library

Yes

Mocks are available from the library unittest.mock which allows you to replace parts of your system under test with mock objects
Grouping
Allows organizing tests in groups

Yes

The short answer is yes, by use of table tests which are a great way of performing multiple I/O tests on a function or behaviour with minimal code

Yes

One can build suites either manually or use test discovery to build the suite automatically by scanning a directory
