Enhance PHP vs Concordion comparison of testing frameworks
What are the differences between Enhance PHP and Concordion?

	Enhance PHP http://www.enhance-php.com/	Concordion https://concordion.org/
Programming language	PHP	Java
Category	Unit Testing
General info	Enhance PHP is a lightweight Open Source PHP unit testing framework It has support for mocks and stubs and runs in the browser, or via the command line	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.
xUnit Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.	No	No
Client-side Allows testing code execution on the client, such as a web browser	Yes It tests front-end functionality and can run in the browser	Yes You can specify tests for front-end components and functionality with concordion
Server-side Allows testing the bahovior of a server-side code	N/A	Yes You can test server-side components and functionality with concordion.
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes One is able to write fixtures in Enhance PHP	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
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 is able to write group fixtures in Enhance PHP	Yes One can group fixtures in concordion
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	N/A
Licence Licence type governing the use and redistribution of the software	Apache License 2.0	Apache License 2.0
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 Enhance PHP has built-in support for mocks and stubs. You can set up expectations and supply predictable return values	Yes By use of third party libraries like mockito
Grouping Allows organizing tests in groups	Yes You can group tests into suites with Enhance PHP	Yes One can group tests into suites
