What are some popular libraries for testing asynchronous actions?
Some popular libraries for testing asynchronous actions include Jest, Mocha, and Cypress. They provide great support for async testing.
Can you explain how to use Jest for testing async functions?
Sure! In Jest, you can test async functions using 'async/await' or by returning a promise. Just make sure to use 'test' or 'it' blocks.
What about error handling in async tests?
For error handling, you can use 'try/catch' blocks within your async functions or use Jest's 'rejects' matcher to assert promise rejections.
Are there any best practices for testing async code?
Yes, some best practices include keeping tests isolated, using mock functions, and ensuring that your tests run quickly to avoid timeouts.
