AVA vs Enzyme: What are the differences?
What is AVA? A refined, futuristic test runner. Even though JavaScript is single-threaded, IO in Node.js can happen in parallel due to its async nature. AVA takes advantage of this and runs your tests concurrently, which is especially beneficial for IO heavy tests. In addition, test files are run in parallel as separate processes, giving you even better performance and an isolated environment for each test file.
What is Enzyme? JavaScript Testing utilities for React, by Airbnb. Enzyme is a JavaScript Testing utility for React that makes it easier to assert, manipulate, and traverse your React Components' output.
AVA and Enzyme can be primarily classified as "Javascript Testing Framework" tools.
AVA and Enzyme are both open source tools. It seems that Enzyme with 17.5K GitHub stars and 1.93K forks on GitHub has more adoption than AVA with 16.5K GitHub stars and 1.08K GitHub forks.
According to the StackShare community, Enzyme has a broader approval, being mentioned in 52 company stacks & 32 developers stacks; compared to AVA, which is listed in 12 company stacks and 10 developer stacks.
Postman will be used to do integration testing with the backend API we create. It offers a clean interface to create many requests, and you can even organize these requests into collections. It helps to test the backend API first to make sure it's working before using it in the front-end. Jest can also be used for testing and is already embedded into React. Not only does it offer unit testing support in javascript, it can also do snapshot testing for the front-end to make sure components are rendering correctly. Enzyme is complementary to Jest and offers more functions such as shallow rendering. UnitTest will be used for Python testing as it is simple, has a lot of functionality and already built in with python. Sentry will be used for keeping track of errors as it is also easily integratable with Heroku because they offer it as an add-on. LogDNA will be used for tracking logs which are not errors and is also a Heroku add-on. Its good to have a separate service to record logs, monitor, track and even fix errors in real-time so our application can run more smoothly.
