Jasmine vs QUnit: What are the differences?


This Markdown code presents the key differences between Jasmine and QUnit, two popular JavaScript testing frameworks.

  1. Syntax: Jasmine uses a behavior-driven development (BDD) syntax, which makes tests more readable and understandable to non-technical stakeholders. On the other hand, QUnit follows a more traditional, assertion-based syntax that is familiar to developers experienced with unit testing frameworks like JUnit.

  2. Matchers: Jasmine provides a rich set of built-in matchers, allowing for expressive and flexible expectations when writing tests. QUnit, on the other hand, has a limited set of built-in matchers but allows for custom assertion methods to be created for more complex scenarios.

  3. Asynchronous Testing Support: Jasmine includes built-in support for asynchronous testing through the use of the done function, making it easier to handle asynchronous operations and assertions. In QUnit, asynchronous testing support is achieved by using the async module, which requires additional setup and teardown code.

  4. Test Organization: Jasmine allows tests to be organized into suites and specs, providing a hierarchical structure for organizing test cases and increasing readability. QUnit, on the other hand, follows a flat structure where tests are defined as functions, without a built-in mechanism for hierarchical organization.

  5. Integration: Jasmine provides built-in support for integration with popular JavaScript frameworks and libraries like AngularJS and jQuery. This allows for seamless integration with existing projects and simplifies the setup process. QUnit does not have the same level of built-in integration with other frameworks, requiring additional setup and configuration.

  6. Test Runner: Jasmine includes its own test runner, which provides a simple and intuitive interface for running tests, viewing test results, and generating test reports. QUnit, on the other hand, does not include a built-in test runner, requiring a separate test runner or custom setup for execution.

In summary, Jasmine and QUnit have key differences in their syntax, matcher capabilities, asynchronous testing support, test organization, integration with other frameworks, and test runner availability.

Decisions about Jasmine and QUnit

We use Mocha for our FDA verification testing. It's integrated into Meteor, our upstream web application framework. We like how battle tested it is, its' syntax, its' options of reporters, and countless other features. Most everybody can agree on mocha, and that gets us half-way through our FDA verification and validation (V&V) testing strategy.
