我有一個反應的項目,我試圖建立一些測試設置玩笑和酶,以測試陣營15找不到模塊反應/ lib目錄/ ReactTestUtils
由於以下安裝指南/問題:
- https://github.com/facebook/jest/issues/1353,
- https://github.com/facebook/react/issues/7386,
- http://facebook.github.io/jest/docs/tutorial-react.html#content,
- http://airbnb.io/enzyme/
我已經安裝了下列相關性:
- 反應-插件 - 測試 - utils的15.3.2
- 反應15.4.0-rc.4
- 反應-DOM 15.4.0-RC -4
- 開玩笑16.0.2
- 巴貝爾-開玩笑16.0.0
- 巴別預置-ES2015 6.18.0
- 巴貝爾-PR ESET-ES2015寬鬆7.0.0
- 巴別預置反應的6.16.0
我的package.json包含以下玩笑配置:
"jest": {
"bail": false,
"collectCoverage": true,
"collectCoverageFrom": [
"<rootDir>/src/**/*.js",
"!<rootDir>/node_modules/**"
],
"coverageDirectory": "coverage",
"coveragePathIgnorePatterns": [
"<rootDir>/node_modules"
],
"coverageThreshold": {
"global": {
"branches": 50,
"functions": 50,
"lines": 50,
"statements": 50
}
},
"globals": {
"SOURCEMAP": true
},
"modulePaths": [
"<rootDir>/src",
"<rootDir>/sass",
"<rootDir>/public",
"<rootDir>/node_modules"
],
"resetModules": true,
"testPathDirs": [
"<rootDir>/test"
],
"testRegex": "(/test/.*|\\.(test|spec))\\.(js|jsx)$",
"verbose": true
}
我有組分(GenericButton)放置在<rootDir>/components/buttons/GenericButton.js
和我的<rootDir>/test/componnets/buttons/GenericButtonTest.js
測試與內容如下:
import React from 'react';
import GenericButton from 'components/buttons/GenericButton';
import { shallow } from 'enzyme';
import { shallowToJson } from 'enzyme-to-json';
import ReactTestUtils from 'react-addons-test-utils'
describe('Generic Button',() => {
test('Button action called when clicked',() => {
var clicked = false;
const component = shallow(
<GenericButton action={() => {
clicked = true;
}}/>
);
console.log("Clicking the button!");
ReactTestUtils.Simulate.click(component);
expect(clicked).toBeTruthy();
});
})
我babelrc文件如下:
{
"presets": [
"es2015-loose",
"react",
"stage-0"
],
"plugins": [
"babel-root-slash-import",
"transform-decorators-legacy",
"react-hot-loader/babel",
"transform-runtime"
],
"compact": true,
"ignore": [
"/node_modules/(?!react-number-input)"
]
}
但是當我跑我的測試,我得到以下錯誤:
> [email protected] test C:\path\to\project
> jest
FAIL test\components\buttons\GenericButtonTest.js

我能做些什麼,使這個簡單的測試通過了嗎?
編輯:文件反應/ LIB /起反應-插件 - 測試 - utils的正在請求是不是在node_modules ReactTestUtils /反應/ lib文件夾。
這是固定通過升級反應 - 插件 - 測試 - utils的到15.4.0,rc.3但後來我:

我的答案中有一個錯字。 –
錯誤解決。現在: 方法「道具」只能在單個節點上運行。 0代替。在ShallowWrapper.props(node_modules \ enzyme \ build \ ShallowWrapper.js:791:21)上ShallowWrapper.single(node_modules \ enzyme \ build \ ShallowWrapper.js:1401:17) ----- ShallowWrapper.prop(node_modules \ enzyme \ build \ ShallowWrapper.js:997:21) -----在ShallowWrapper.simulate(node_modules \ enzyme \ build \ ShallowWrapper.js:762:28) -----在對象。(test \ components \ buttons \ GenericButtonTest.js:17:33) ----- at process._tickCallback(internal \ process \ next_tick.js:103:7) –
