AVA vs SinonJS: What are the differences?

# Differences between AVA and SinonJS

<Write Introduction here>

1. **Test Runner**: AVA is a test runner that runs tests concurrently, providing faster results, while SinonJS is a standalone stub/spy framework used for component testing.
2. **Scope**: AVA is more focused on providing a test runner with good performance, whereas SinonJS is focused solely on providing functionalities like stubs, spies, and mocks for testing.
3. **Parallelism**: AVA runs tests in parallel by default, allowing for quicker test execution, while SinonJS does not offer parallel test execution out of the box.
4. **Assertion Library**: AVA comes with its built-in assertion library, making it easier to write test cases, whereas SinonJS does not provide an assertion library and needs to be combined with other libraries like Chai for assertions.
5. **API Mocking**: SinonJS excels in mocking HTTP requests, timers, and other network interactions with its powerful API mocking capabilities, which AVA does not specialize in.
6. **Community Support**: AVA has a robust community and active development, frequently updating the tool with new features and improvements, while SinonJS also has good community support but may not be as actively developed as AVA.

In Summary, AVA and SinonJS serve different purposes in the testing ecosystem, with AVA being a test runner focused on performance and parallel execution, while SinonJS specializes in providing tools for stubbing, spying, and mocking in tests.
