creating a brand new serverless project. In this post, I’d like to share with you my serverless-specific IDE setup, and how it can massively accelerate your serverless workflow. And I recently thought to myself, “Oh, I bet lots of other serverless devs out there might find this useful!” Over the past few years, I’ve been fortunate enough to work exclusively on serverless tooling.ĭuring that time, I put together a certain workflow that integrates quite nicely with my IDE of choice: WebStorm. At first, when the vision of an application is not clear, unit testing might slow down development, but once a vision is established and real users will be interacting with the application, unit tests (and other types of automated tests) are absolutely essential to ensure the codebase is maintainable and scalable.If you build serverless applications, here’s a serverless-specific IDE setup that will help you streamline your workflow. Unit testing is an important part of any serious application. More information about testing Vue components can be found in Testing Vue.js Applications by core team member Edd Yerburgh. These usually run pre-deploy, to ensure each part of the system is working together correctly. Higher level tests, such as end to end tests, run much slower. WEBSTORM DEBUG JEST HOW TO
Unit tests are most useful during development, either to help a developer think about how to design a component, or refactor an existing component, and are often run every time code is changed. These are slower to run than unit tests or snapshot tests.
WEBSTORM DEBUG JEST UPDATE
Some examples might be testing if a user can sign up, log in, and update their username. If something changes, the developer is notified, and can decide if the change was intentional (the component was updated) or accidental (the component is behaving incorrectly).Įnd to end tests ensure a number of components interact well together. Snapshot tests save the markup of your Vue component, and compare to the new one generated each time the test runs. Unit tests are the smallest and most simple of tests - they make assertions on the smallest units of work, isolating each part of a single component. Some other types of tests include e2e (end to end) tests, and snapshot tests. Unit tests are only one part of the testing pyramid, though. Vue Test Utils and the enormous JavaScript ecosystem provides plenty of tooling to facilitate almost 100% test coverage. There are more complete examples showing such tests in the Vue Test Utils guides.
committing or dispatching mutations or actions with a Vuex store. The above test is fairly simple, but in practice Vue components often have other behaviors you want to test, such as: Another great benefit to this is when more complex components with a method or computed property you might want to mock or stub in every test, you only need to declare it once. This way, we don’t need to duplicate const wrapper = shallowMount(Foo) in every test. toBeFalsy()Īt the top, we declare the factory function which merges the values object into data and returns a new wrapper instance. This simple example tests whether some text is rendered: This lets you develop new features with confidence you are not breaking existing ones, and helps other developers understand what your component does. Vue’s single-file components make it straight forward to write unit tests for components in isolation. 
Unit tests execute the smallest units of code in isolation, in order to increase ease of adding new features and track down bugs.
