HTML标签的反应/酶测试值?

<label id="userInfo"><b>Logged in as: </b>{principal.emailAddress}, <b>Role: </b>{userRole}</label>

这是我的测试,目前不起作用:

describe("Testing User Info displaying correctly", () =>{
  it("when provided principal data, it should correctly combine the username and role", () => {
    expect(wrapper.find('[data-test-id="userInfo"]').text()).to.equal("Logged in as: jdoe@foo.bar, Role: Subscriber");
    });
});

当前测试失败,并显示以下消息:

"Method “text” is only meant to be run on a single node. 0 found instead."
