Allows easy testing of redux-sagas without having to mock anything.
npm install --save-dev @mt-testutils/test-saga
Let's assume we have a generator function like this:
function* mySaga() {
try {
const value1 = put(someAction);
yield value1;
} catch (e) {
yield 'ERROR';
}
}
With this helper function, we can easily test the generator, by writing one it test per yield expression:
import mySaga from './mySaga';
import testSaga from '@mt-testutils/test-saga';
testSaga(mySaga(), () => {
it('should yield a put', nextYield => {
nextYield.should.equal(put(someAction));
return 'hello world'
});
it ('should yield the return value from last yield', nextYield => {
nextYield.should.equal('hello world');
return new Error('ERROR');
});
it ('should yield the error thrown by last yield', nextYield => {
nextYield.should.equal('ERROR');
});
});
