Ich versuche einen Knopfklick mit Enzym zu simulieren. Ich bin in der Lage, einfache Tests zu schreiben, wenn ein Element rendert, aber die Spaßtests, wie Knopfklicks usw., sind nicht ausreichend.Die Taste zum Simulieren der Klick-Taste kann nicht gefunden werden. - Unit Testing Reagieren mit Mocha, Chai, Enzym
In diesem Beispiel wird der Fehler im Terminal ist:
1) Front End @Profile Component clicks a button :
Error: This method is only meant to be run on single node. 0 found instead.
at ShallowWrapper.single (node_modules/enzyme/build/ShallowWrapper.js:1093:17)
at ShallowWrapper.props (node_modules/enzyme/build/ShallowWrapper.js:532:21)

at ShallowWrapper.simulate (node_modules/enzyme/build/ShallowWrapper.js:505:28)
at Context.<anonymous> (cmpnt-profile.spec.js:36:32)
der Unit-Test ist:
describe('Front End @Profile Component',() => {
const wrapper = shallow(<Profile/>);
...(other tests here)...
it('clicks a button ',() => {
wrapper.find('button').simulate('click');
expect(onButtonClick.calledOnce).to.equal(true);
})
});

Irgendwelche Vorschläge geschätzt. Ich würde gerne einige erstaunliche Unit Tests machen!
Ich habe versucht, Standard von Klasse Profil, sowie die Redux-Form zu entfernen, und es führte zu einigen Fehlern. Hier ist eine davon, den Export aus der Klasse zu entfernen. –
'bei Parser.pp.raise (/../fairshare/divvy/node_modules/babylon/index.js:1378:13) bei Parser.pp.unexpected' –
ps. um es zu verdeutlichen, habe ich versucht, sie nacheinander zu entfernen, nicht beide gleichzeitig. –
