Concordion vs go test/testing comparison of testing frameworks
What are the differences between Concordion and go test/testing?

	Concordion https://concordion.org/	go test/testing https://golang.org/pkg/testing/
Programming language	Java	Go
Category		Unit Testing
General info	Concordion is a tool used to write and manage automated acceptance tests in Java based projects Concordion specifications are written in Markdown, HTML or Excel and then instrumented with special links, attributes or comments respectively. When the corresponding test fixture class is run, Concordion interprets the instrumentation to execute the test. Concordion lets you write them in normal language using paragraphs, tables and proper punctuation. This makes specification more natural to read and write, and helps everyone to understand and agree about what a feature is supposed to do.	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.	No	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 You can specify tests for front-end components and functionality with concordion	Yes Yes it can be used effectively for front-end testing
Server-side Allows testing the bahovior of a server-side code	Yes You can test server-side components and functionality with concordion.	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	Yes Concordion contains fixtures which correspond to a specific instrumentation within the code. That is when specifications are written they are instrumented with special links, attributes or comments which are then run with their corresponding fixtures	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.	Yes One can group fixtures in concordion	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.	N/A	Yes They are available by importing a package called 'gotests' (https://github.com/cweill/gotests)
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	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 third party libraries like mockito	Yes By use of a third party library GoMock which intergrates well with the testing library
Grouping Allows organizing tests in groups	Yes One can group tests into suites	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
