How to drag and drop in Cypress.io

Question

I am testing Trello and trying to drag the last list and then drop it into a penultimate column, but the test is not working without ".wait". It would be really helpful if someone could advise about the potential issue here because I prefer to avoid using ".wait". There are no errors throwing, but still, the drag and drop is not happening without ".wait".

describe("Moving list", () => {
  it("Waiting For Accept list should be moved from last column to the penultimate column", () => {
    cy.get("#board")
      .children(".js-list")
      .should("have.length", 4)
      .and("be.visible");

    cy.get(":nth-child(4) > .list")
      .should("be.visible")
      .and("contain", "Waiting For Accept")

    cy.get(":nth-child(4) > .list").trigger("mousedown", {
      which: 1
    });

    cy.get("#board > div:nth-child(2) > .list")
      .trigger("mousemove");

    cy.get("#board > div:nth-child(3) > .list")
      .trigger("mousemove")
      .trigger("mouseup");

    cy.get(":nth-child(3) > .list")
      .should("contain", "Waiting For Accept");
  });
});

That doesn't work out of the box, the logged issue for that is https://github.com/cypress-io/cypress/issues/845 . But in that same ticket is also a work around available using the native drag and drop API with draggable attribute on draggable elements:

Create a custom command

Cypress.Commands.add("dragTo", { prevSubject: "element" }, (subject, targetEl) => {
    cy.wrap(subject).trigger("dragstart");
    cy.get(targetEl).trigger("drop");
  }
);

In the testscript you can use:

cy.get(".source").dragTo(".target");

You can use the Cypress drap and drop plugin

Finally I resolved this issue by using "cy.request"

https://docs.cypress.io/api/commands/request.html#Syntax

describe("Moving list", () => {
        it("Waiting For Accept list should be moved from last column to the penultimate column", () => {
            cy.request("https://trello.com/b/9lfzKIRu/trello-tests").then(response => {
                expect(response.status).to.eq(200);
            });
            cy.get("#board > div:nth-child(4) > .list").trigger("mousedown", {
                which: 1
            });
            cy.get("#board > div:nth-child(2) > .list").trigger("mousemove");
            cy.get("#board > div:nth-child(3) > .list")
                .trigger("mousemove")
                .trigger("mouseup");
            cy.get(":nth-child(3) > .list").should("contain", "Waiting For Accept");
        });
    });

最好的解决方案是使用https://github.com/4teamwork/cypress-drag-drop它也支持拖动到顶部和底部。

        cy.get('#placeholder-3').drag('#placeholder-2', {            position: 'top', })

I solved it by downgrading my drag and drop version from 2.1.0 to 1.8.0
