Jasmine vs Spek comparison of testing frameworks
What are the differences between Jasmine and Spek?

	Jasmine https://github.com/jasmine/jasmine	Spek https://www.spekframework.org/
Programming language	JavaScript	Kotlin
Category	Unit Testing, End-to-End Testing	Acceptance Testing, Unit Testing
General info	JS Unit test framework, BDD based for Node.JS applications used with Angular.JS web applications and also paired with 'Karma' task runner It's a BDD (Behavior Driven Development) test framework for JavaScript especially designed for manual QAs to understand the automation tests. It does not depend on the any JavaScript framework or browser. So it's very well suited for Node.js projects and websites	Spek is a specification framework for Kotlin Spek is a Kotlin-based Specification Testing framework for the JVM. It works as a JUnit 5 Test Engine meaning that we can easily plug it into any project that already uses JUnit 5 to run alongside any other tests that we might have.
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 Jasmine works well in and with browsers to test client-side components and functionality	Yes Yes you can test front-end behaviour by writing specifications to test front-end functionality. Developers can also write unit tests for individual front-end components.
Server-side Allows testing the bahovior of a server-side code	Yes Jasmine works with NodeJs to test its back-end components and behaviour	Yes You can test back-end behaviour and componets by writing specifications to test back-end functionality and unit tests for individual back-end components
Fixtures Allows defining a fixed, specific states of data (fixtures) that are test-local. This ensures specific environment for a single test	Yes By using 'jasmine-fixture' which can help write specs that interact with the DOM making it easier to injectHTML fixtures	Yes Fixtures are available in spek through functions suchas beforeEachTest() and afterEachTest()
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 spek has group fixtures available through the beforeGroup() and afterGroup() functions
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	MIT License	Modified BSD 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)	By using a a plugin called jasmine-ajax that allows ajax calls to be mocked out in tests	Yes You can use the third party library mockito-kotlin
Grouping Allows organizing tests in groups	Yes Using the describe function which is for grouping related tests, typically each test file has one at the top level.	Yes Tests are written using nested lambdas, each scope (level) can either be a group or a test
