Question

我已经从该站点的material-ui测试页面中举了一个例子。我已经使用create-react-app制作了该应用，并将酶导入了我的项目。

import { createMount } from '@material-ui/core/test-utils';
import MyComponent from './src/MyComponent';

describe('<MyComponent />', () => {
  let mount;

 before(() => {
   mount = createMount();
});

after(() => {
   mount.cleanUp();
});

it('should work', () => {
   const wrapper = mount(<MyComponent />);
 });
});

我所有的测试均无法运行并引发以下错误 ReferenceError: before is not defined

我读过的任何地方都不需要配置玩笑，因为它与create-react-app开箱即用。下面是我的package.json，我应该如何配置我的应用程序以便可以运行这些测试？

您需要先更改为beforeAll，然后再更改为afterAll

更改

import networkx
import pandas as pd

d = {'Col1': {'row1': 'A1',
  'row2': 'A2',
  'row3': 'A2',
  'row4': 'A3',
  'row5': 'B1',
  'row6': 'B2'},
 'Col2': {'row1': 'A2',
  'row2': 'A3',
  'row3': 'A4',
  'row4': 'A5',
  'row5': 'B2',
  'row6': 'A3'}}

df = pd.DataFrame(d)


G = nx.from_pandas_edgelist(df, 'Col1', 'Col2', create_using=nx.DiGraph())

master = [n for n in G.nodes if nx.ancestors(G, n)==set()]
descendants = [list(nx.descendants(G,m)) for m in master]

pd.DataFrame({'col1':master,'col2':descendants})

  col1              col2
0   A1  [A3, A5, A4, A2]
1   B1      [A5, A3, B2]
