【问题讨论】：

在javascript中，只需在对象上调用.length。您能否向我们展示这些 console.log 是如何完成的：您的源代码是什么？

既然这只是一个数组，你应该断言它的长度为 42。你应该能够将它从 BODY 上拉下来。

如果长度增加，你的测试不会因此而失败吗？您能否向我们展示调用此 API 的代码或您当前的测试。我想提供帮助，但我需要更多信息。

@Kashif 你需要展示你的测试代码才能帮助你

到底是什么失败了？发生了很多事情......

【参考方案1】：

我终于成功了

describe("Partie Counts Profile Page Test", () => 
  before(function() 
    cy.SignIn();
    cy.fixture("vars.json").as("vars");
  );

  it("Partie Counts", () => 
    const profileBtn = "div.actions--left > button > img";

    ///// I want to get lenght of the parties from the url response and want check with counts in UI
    cy.wait(3000);
    cy.get(profileBtn).click();
    cy.wait(1000);

    cy.server();
    cy.route(
      method: "GET",
      url: "api/v1/room/getUserRooms/d23eef09-e4e1-455d-a74c-03dfc61bde11"
    ).as("get_jobs");
    
    cy.wait("@get_jobs").then(xhr => 
      cy.log(xhr.response.body.length);
      cy.get("div:nth-child(3) > span.quick-stat-figure").should(
        "contain",
        xhr.response.body.length
      );
    );
  );
);
