Looking to verify responsiveness in Material-UI?
Here is an example:
import React from "react";
import Hidden from "@material-ui/core/Hidden";
const HideOnMobile = (props) => {
return <Hidden xsDown>{props.children}</Hidden>;
};
Check out these test scenarios:
describe(HideOnMobile, () => {
describe("when screensize is sm", () => {
it("shows children", () => {});
});
describe("when screensize is xs", () => {
it("hides children", () => {});
});
});
MUI Version 5
Unfortunately, the solution that worked for MUI version 4 does not work for version 5.
MUI Version 4
As mentioned here, you can use theme props to set size properties for Material-UI:
import { createMuiTheme, MuiThemeProvider } from "@material-ui/core/styles";
const SizeWrapper = (props) => {
const theme = createMuiTheme({
props: { MuiWithWidth: { initialWidth: "sm" } },
});
return <MuiThemeProvider theme={theme}>{props.children}</MuiThemeProvider>;
};
For example, when using React Testing Library:
describe(HideOnMobile, () => {
describe("when screensize is sm", () => {
it("shows children", () => {
const testMessage = "Test Message";
render(<HideOnMobile>{testMessage}</HideOnMobile>, { wrapper: SizeWrapper });
expect(screen.getByText(testMessage)).toBeInTheDocument();
});
});
});
