What are some effective testing strategies for dynamically typed languages?

In dynamically typed languages, you can use strategies like unit testing, integration testing, and property-based testing. Unit tests help ensure individual components work as expected, while integration tests check how different parts of your application interact. Property-based testing allows you to define properties that should hold true for a wide range of inputs.

Can you explain how unit testing works in these languages?

Sure! Unit testing involves writing test cases for individual functions or methods. In dynamically typed languages, you typically use frameworks like Jest for JavaScript or PyTest for Python. You write assertions to check if the output of a function matches the expected result for given inputs.

What about integration testing? How is it different?

Integration testing focuses on the interactions between different modules or services. Unlike unit tests, which test components in isolation, integration tests ensure that combined parts of your application work together correctly. This is crucial in dynamically typed languages where type errors may only surface during runtime.

Are there any tools you recommend for testing?

Yes! For JavaScript, Jest and Mocha are popular choices. For Python, you can use PyTest or Unittest. Additionally, tools like Postman can be great for API testing, and Cypress is excellent for end-to-end testing.
