Thus, component from hocdirectory was present in widgets component that’s why I already know where and with which purpose this directory and its component are used. How do you define which one should be tested first? I take the directory from which components have already been used in tested components. They are hoc directory and fieldsfrom forms folder. The most complex for testing components are left in the end.It is modals directory in our case these components will be explained in detail below. Further, analyze the rest of the directories and define more complex components, which can be used independently or in conjunction with other components.They will be the third item in the queue for test coverage. From our structure, it is widget little components with simple functionality. The next step is to define which components can be used independently too.They are frequently reusable and help with repeated actions. Components in this folder are not complicated, but very important. Next, I need to define auxiliary components that are often used in inputs components but should be tested apart from them.It contains input components to redux-forms, such as TextInput, SelectInput, CheckboxInput, DateInput, etc. From the structure above, it is input directory in forms folder. Analyze each directory and define which components are independent - namely, their rendering doesn’t depend on the other components they are self-completed and can be used separately as a single unit. Always follow the rule from simple to complex.

As well, there is no guarantee it will notify you if something has been changed. Even more, 100% test coverage does not always ensure that the component is fully tested. We will find out why and what should be left out of tests. Why? Because you shouldn’t test all code. Information about installation and configuration can be easily found on the web or official websites.Īssume the following case: You need to cover the project codebase with tests, so what should you start with and what should you get at the end of testing? 100% test coverage? It is the indicator to which you should aspire, but in most situations, you won’t get it. The article requires that the reader already has knowledge about Jest and Enzyme setup.

Define what to test in the component and in which order.

Identify the necessity of Snapshot Testing.

Find what to omit in test coverage (what not to test).

Define the correct order of components’ testing based on project structure.

If you are interested in actual logic, please refer the code.During the reading, I’ll cover the next topics: withStyles HOC returns component with classes attribute and link your styles object to component. The magic happens in the last line withStyles. Index.tsx ReactDOM.render(, document.getElementById('root'), ) Īnd each child component looks like below. To use it, normally you provide theme in your root component which used React context API. With MUI, you can define your own theme and write CSS in JS.

Snapshots of Material UI styled component with React Testing Library and TypeScript.

How to Write Tests with React Testing Library and TypeScript: Implement the basic AAA testing pattern today.

The Practical Guide to Start React Testing Library with TypeScript.

If you would like to know other topics of React Testing Library, please refer the articles below. So this article explains how to setup React Testing Library for Material UI styled component with TypeScript. However, because Material UI (MUI) styled component use HOC (Higher Order Component), setup is bit complicated. When it comes to frontend, React Testing Library is becoming popular because it’s easier to test React hooks compared with enzyme. It enables us to change codes more speedy with less bugs.
