Premium questions with real-world problems
The React online test assesses candidates' knowledge of programming using the React/ReactJS library and their ability to leverage commonly used programming patterns.
It's an ideal test for pre-employment screening. A good React developer needs to be able to solve problems using the React library and also know how to solve problems in the React way.
This test asks candidates to solve coding problems in React and find and fix bugs in React programs.
TestDome is trusted by businesses large and small

Free Sample Questions for React Test
Our sample questions are free for companies to use on a trial plan. See more about our premium questions for paid plans below.
Toggle Message
The Message component contains an anchor element and a paragraph below the anchor. Rendering of the paragraph should be toggled by clicking on the anchor element using the following logic:
- At the start, the paragraph should not be rendered.
- After a click, the paragraph should be rendered.
- After another click, the paragraph should not be rendered.
Finish the Message component by implementing this logic.
Focus
The TextInput component renders an input element in the DOM and accepts a ref that is forwarded to that input element. Finish the FocusableInput component:
- The component should accept a focused prop.
- When the focused prop is changed from false to true, and the input is not focused, it should receive the focus.
- If on mounting the focused prop is true, the input should receive the focus.
Todo List
Write a TodoList component that expects an items prop which is a list of objects, each with text and done properties.
TodoList also accepts an onItemClick function prop, which should be called when a user clicks an item in the list, if the item is not marked as done. Otherwise, the onItemClick should not be called and the click event itself should not be propagated further. The function should be called with the item object from the items list as the first parameter and the event as the second parameter.

Pass/fail grouping
Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.
Full customization
We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.
Cheating protection
Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.
Candidate reporting
Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
