问题
When scaffolding a new project with the Vue.js CLI, it offers a choice of both unit-testing and E2E-testing frameworks.
Unit-testing functionality is perfectly adequate in Cypress. My question, then: is there an advantage to using a distinct unit-testing framework if I'm already using Cypress?
回答1:
There is a third-party adapter made by a Cypress contributor here called cypress-vue-unit-test(along with unit-test adapters for other popular frameworks).
You should check that out and see if it meets your needs over, say, Jest
From this tutorial about unit testing vuejs, some Jest advantages over Cypress are:
- Built in code coverage
- Snapshot testing
- Module mocking utilities
