我正在使用涉及登录的karma + jasmine对React Components进行单元测试。测试总是抛出错误
? LoginForm test > ValidatedInput test > should validate password

LoginForm.js呈现组件
<ValidatedInput
name={'userId'}

title={'User ID'}

placeholder={'Enter User ID'}
onChange={this.handleUserIdChange}
onComponentMounted={this.handleRegisterFormFields}

isRequired={true}
/>

handleUserIdChange(value) { …
