Jasmine follows a Behavior Driven Development (BDD) testing style, providing a more expressive syntax for test cases. Ava, on the other hand, adopts a more minimalist and straightforward approach to testing.
Jasmine uses a declarative syntax with functions such as 'describe', 'it', and 'expect' to structure test suites and assertions. Ava uses ES2017 async/await syntax for writing test cases, making it easier to handle asynchronous code.
Ava is known for its concurrent test execution, which allows test cases to run in parallel by default, resulting in faster test execution times. Jasmine runs tests serially and does not have built-in support for parallel execution.
Jasmine is easy to set up and configure with minimal configuration required. Ava is also easy to configure, but it offers more customization options such as configuring test retries, environment variables, and parallel test settings.
Community and Ecosystem
Jasmine has a larger community and a well-established ecosystem with a wide range of plugins and extensions available. Ava has a smaller but growing community, and its ecosystem is expanding with new plugins being developed.
Both Ava and Jasmine have comprehensive documentation, but Jasmine's documentation is more extensive and covers a wider range of topics, making it easier to learn and troubleshoot. Ava's documentation is concise but provides enough information to get started quickly.
