General info

Cedar is a BDD-style testing for swift using Objective-C

Cedar is a BDD-style Objective-C/Swift testing framework that has an expressive matcher DSL and convenient test doubles (mocks). It provides better organizational facilities than the tools provided by XCTest/OCUnit In environments where C++ is available, it provides powerful built-in matchers, test doubles and fakes

Cucumber-JVM is a pure Java implementation of Cucumber

The specifications are written in plain texts, which allows them to be easily understandable by all stakeholders.
xUnit
Set of frameworks originating from SUnit (Smalltalk's testing framework). They share similar structure and functionality.

Yes

Cedar is an xUnit style framework

No

Client-side
Allows testing code execution on the client, such as a web browser

Yes

You can test front-end components and behaviour with Cedar, its language is biased towards describing the behavior of your objects.

Yes

You can test the front-end part like the GUI using cucumber with serenity, they integrate well to test your front-end.
Server-side
Allows testing the bahovior of a server-side code

Yes

You can test back-end components with a bias towards their expected behaviour. Cedar specs also allow you to nest contexts so that it is easier to understand how your object behaves in different scenarios

Yes

You can test back-end components such as API's using rest&soap clients, and databases
Fixtures
Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test

Yes

Cedar has beforeEach and afterEach class methods which Cedar will look for on every class it loads. You can add these onto any class you compile into your specs and Cedar will run them

Yes

Using the cucumber extension aruba you can create fixures in two steps: 1.Create a fixtures-directory; 2.Create fixture files in this directory
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

Yes

You can group your fixtures inside your fixtures directories
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.

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

Cedar contains inbuilt mock/test double functionality

Yes

By using all of RSpec’s supported mocking frameworks (RSpec, Mocha, RR, Flexmock)
Grouping
Allows organizing tests in groups

Yes

Cedar supports shared example groups. You can declare them in one of two ways: either inline with your spec declarations, or separately.

Yes

Cucumber allows the use of tag Cucumber feature files or individual tests to group tests. Then, you can pass a Cucumber tagged expression at test execution that specifies the tag (grouped) tests to run. https://www.toolsqa.com/cucumber/cucumber-tags/
