I'm having an actual class like this
my-file.js
const methodA = () => { return 'output-from-methodA'; }
const methodB = () => { const b = methodA(); b.c = "out-put bind"; return b; }
module.exports = {
methodB
}
my-file.test.js
const { methodA, methodB } = require('./my-file.js');
describe('methodB testing', () => {
it('should call methodA', () => {
methodB();
expect(methodA).toHaveBeenCalled()
}
});
here methodA is private method, so it is not explicit to the test file, then how i ensure it is called or not in the test files
There is no way to test the private function, only the alternative way found is to test the outputs like
const { methodA, methodB } = require('./my-file.js');
describe('methodB testing', () => {
it('should call methodA', () => {
const result = methodB();
expect(result.b.c).toBe("out-put bind")
}
});
