General info

Mocha is a widely used JavaScript test framework for Node.js

Mocha is a simple, flexible and the one of the widely adopted JS test framework. Mocha usually runs tests serially which enables the accurate reporting. Also it's useful for asynchronous testing, and provides various king of test reports. Spec is default test reporter for mocha, there are many test reports like Nyan, Dot matrix, Tap, Landing strip, List and Progress. Mocha is being used with many other test frameworks like Selenium WebDriver, Webdriver.io, wd and Cypress

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
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

It has an XUnit reporter available which outputs an XUnit-compatible XML document, often applicable in CI servers.

No

However there are Plugins such as https://github.com/tebeka/go2xunitto convert the output of Go testing library into xUnit format
Client-side
Allows testing code execution on the client, such as a web browser

Yes

Mocha Runs in the browser and is used widely to test front-end components and functionality. It can test various DOM elements, front-end functions and so on.

Yes

Yes it can be used effectively for front-end testing
Server-side
Allows testing the bahovior of a server-side code

Yes

Mocha provides convenient ways of testing the Node server.It works well with Chai (an assertion library) where it provides the environment for writing server-side tests while we write the tests with Chai

Yes

Yes, it is used by developers for end-to-end testing so the back-end can be tested easily as well
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Mocha provides the hooks before(), after(), beforeEach(), and afterEach() to set up preconditions and clean up after your tests

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
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.

N/A

Mocha allows grouping of fixtures

Yes

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

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)

Provides Mocking capabilities through third party libraries like sinon.js, simple-mock and nock

Yes

By use of a third party library GoMock which intergrates well with the testing library
Grouping
Allows organizing tests in groups

Yes

Grouping is supported and is accomplished by the using a nested 'describe()'

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
