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

Pytest is the TDD 'all in one' testing framework for Python

Pytest is a powerful Python testing framework that can test all and levels of software. It is considered by many to be the best testing framework in Python with many projects on the internet having switched to it from other frameworks, including Mozilla and Dropbox. This is due to its many powerful features such as ‘assert‘ rewriting, a third-party plugin model and a powerful yet simple fixture model.
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

No

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

pytest can test any part of the stack including front-end components
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

pytest is powerful enough to test database and server components and functionality
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

Pytest has a powerful yet simple fixture model that is unmatched in any other testing framework.
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

Pytest's powerful fixture model allows grouping of fixtures
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

pytest has a hook function called pytest_generate_tests hook which is called when collecting a test function and one can use it to generate data
Licence
Licence type governing the use and redistribution of the software

MIT License

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

By either using unittest.mock or using pytest-mock a thin wrapper that provides mock functionality for pytest
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

Tests can be grouped with pytest by use of markers which are applied to various tests and one can run tests with the marker applied
