TypeError:当我尝试使用 JEST 测试方法时,调度不是函数

我有一个方法接收一些值作为参数,然后分派一个动作。问题是,当我对组件进行浅层测试以测试此方法时,我有一个错误说调度不是一个函数。

测试:

test('it changes the state when submit is clicked', () => {
    const wrapper = shallow(<WizardForm store={store}/>);
    const values = {
    entrySign: 'archivoSign',
    signCertificateFile: 'file',
    signCertificate: 'text',
    entryAuth: 'notArchivoAuth',
    authCertificateFile: 'file',
    authCertificate: 'text'
}
const form = wrapper.instance();
//in this method I get the error
form.submit(values)

方法:

submit(values) {
  var authCertificate = this.checkAuth(values);
  var signCertificate = this.checkSign(values);
  let req = {
    authCertificate: authCertificate,
    signCertificate: signCertificate,
    userId: this.state.userId
  }
  const { dispatch } = this.props
  dispatch({type: 'CERTIFICATES_FETCH_REQUESTED', payload: {req}})
}

谁能帮我?我不知道我做错了什么。提前致谢!

好的,现在我有这个测试:

it('works', () => {
const values = {
  username: 'marc',
  name: 'marc',
  email: 'marc@hotmail.com',
  entrySign: 'archivoSign',
  signCertificateFile: 'file',
  signCertificate: 'text',
  entryAuth: 'notArchivoAuth',
  authCertificateFile: 'file',
  authCertificate: 'text'
} 
const mapDispatchToProps = (dispatch) => ({
  submit
});
const mockedStore = createMockStore();
const WizardFormWrapper = connect(reduxFormReducer, mapDispatchToProps)(WizardForm);
const wrapper = shallowWithStore(<WizardFormWrapper />, mockedStore);
   wrapper.props().submit();

});        
})

现在我得到的问题是: ReferenceError: submit is not defined 任何建议@RIYAJ KHAN ?
