fastlane vs Jest: What are the differences?
What is fastlane? Connect all iOS deployment tools into one streamlined workflow. fastlane lets you define and run your deployment pipelines for different environments. It helps you unify your app’s release process and automate the whole process. fastlane connects all fastlane tools and third party tools, like CocoaPods.
What is Jest? Painless JavaScript Unit Testing. Jest provides you with multiple layers on top of Jasmine.
fastlane and Jest are primarily classified as "Mobile Continuous Integration" and "Javascript Testing Framework" tools respectively.
Some of the features offered by fastlane are:
- Connect all build tools together
- Define multiple lanes for different needs
- Jenkins Integration
On the other hand, Jest provides the following key features:
- Familiar Approach: Built on top of the Jasmine test framework, using familiar expect(value).toBe(other) assertions
- Mock by Default: Automatically mocks CommonJS modules returned by require(), making most existing code testable
- Short Feedback Loop: DOM APIs are mocked and tests run in parallel via a small node.js command line utility
"Easy to use" is the primary reason why developers consider fastlane over the competitors, whereas "Open source" was stated as the key factor in picking Jest.
fastlane and Jest are both open source tools. Jest with 26.4K GitHub stars and 3.57K forks on GitHub appears to be more popular than fastlane with 26K GitHub stars and 3.97K GitHub forks.
Airbnb, Facebook, and Instagram are some of the popular companies that use Jest, whereas fastlane is used by Intuit, Zola, and Rydite. Jest has a broader approval, being mentioned in 272 company stacks & 161 developers stacks; compared to fastlane, which is listed in 93 company stacks and 22 developer stacks.
