如何使用酶在反应最终形式中测试“提交”？

Question

我使用 react-final-form 库。我用酶+笑话测试它。如何测试 submitting 条件？我不明白如何用酶改变这个值。

const MyForm = (formProps) => {

  return (
    <Form
      mutators={{
      {...formProps}
      render={(renderProps) => {
        const {
          handleSubmit,
          submitting,
        } = renderProps;

        return submitting ? ( // I want to test this condition
          <Spinner />
        ) : (
          <form onSubmit={handleSubmit} className='edit-ukd-form'>
            <div>
              <label>First Name</label>
              <Field
                name="firstName"
                component="input"
                type="text"
                placeholder="First Name"
              />
            </div>
          </form>
        );
      }}
    />
  );
}
