I've started using jest but I've been having some trouble mocking specific JS functions, I've already tried various would be solutions to this but i just couldn't get it to work.
Below is my JavaScript function code
functions.js :
function test1(){
return "hello1"
}
function test2(){
return "hello2"
}
module.exports = test1;
module.exports = test2;
and this is my jest code:
function.test.js
const testfunction = require('/function');
test('tooltip Correct DOM element test', () => {
expect(testfunction.test1).toBe("hello1");
});
You are exporting the function incorrectly. You need to do:
function test1() {
return "hello1"
}
function test2() {
return "hello2"
}
module.exports = {
test1: test1,
test2: test2
};
Exporting the function in this way will enable to get testfunction.test1 inside the test file. And you need to call the function inside the test script like:
expect(testfunction.test1()).toBe("hello1");
