How can I set value to state or props

[MaxnzWZ]

We can obtain value of props or state through getReact(). Can we have some function to set the value to props or state, like setProps and setState in Enzyme?

Hi @MaxnzWZ,
 
There are no such functions in this plugin. Enzyme and TestCafe are different tools and they serve different purposes. Enzyme is a tool for unit testing, so it sees React components as isolated units and allows you to manipulate their props and state (i.e. inputs) and then check a render tree (i.e. output).
TestCafe, in contrast, is a tool for end-to-end testing. Its main idea is to model the entire process of user-application interaction as near to the real life as possible. A user cannot manipulate a component's props and state directly, so TestCafe is also not supposed to do this. Instead, you can emulate a user action that should lead to intended props/state modification and then check how it affects a page state after re-render.
 
Also, direct modification of React component props in the real environment in the middle of the React lifecycle can cause unexpected side-effects, make a test unstable and lead to hard-to-locate bugs.
