Can you import a function from a react component into a test file?

Question

Is there a way to import a function from a react component into a test file?

for example:

component:

const funcToExport = () => {
      let a = 1;
      let b = 2;
      let value = a + b;
      return value
}

test file:

import funcToExport from './component';

can this be done, so you can use the function in the test file?

Answer 1

First of all you have to declare your function globally then add the keyword "export" so you can import it in other files.

export const funcToExport = () => {
      let a = 1;
      let b = 2;
      let value = a + b;
      return value
}
