console error only print {}, without effect message. about cypress-terminal-report HOT 6 CLOSED

Are you sure this is not coming from your app or custom cypress code ? This plugin does not use any .split on anything. I would need more details on this. Maybe the error object format would be a starting point. Don't forget the it might seem that the error is coming from this plugin as it will show up in the stack since we are intercepting (overriding) the original console.error function in the browser.

This message should be a catched error from app, maybe like this code:

var a = 1;
try {
  a.split(",");
} catch (e) {
  // cypress-terminal-report print error line in terminal, but show "cons:error ✘  {}"
  // in browser console, I can get "TypeError: a.split is not a function
  console.error(e); 
}
a.split(","); // make cypress run failed when "uncaught:exception" return true

looks like console.error(error) will print {}, use string is ok.

I tried to reproduce the issue you have with the same code but I couldnt. The issue is that for some reason on your code the error that is thrown is not instance of window.Error. Another possibility is that the error doesnt have the stack property but I doubt that. I have an idea for a possible fix, I will release next week in a patch so we can try if it resolves it for you.

In the meantime:

• what browser do you use?
• do you have any polyfills that might change the error object?
• can you check in the catch whether error instanceof window.Error ?

Browser: Electron 80

Yes

You create a react app to reproduce this issue:

import React, { Component } from "react";
import { Button } from "antd";
import "antd/dist/antd.css";

class App extends Component {
  makeTypeError = () => {
    var a = 1;
    try {
      a.split(",");
    } catch (e) {
      console.error(e);
      console.info(e instanceof window.Error);
    }
    a.split(",");
  };

  render() {
    return (
      <div>
        <Button id="error" onClick={this.makeTypeError}>
          Make Type Error
        </Button>
      </div>
    );
  }
}

export default App;

test code:

describe("foobar", () => {
  it("foobar", () => {
    cy.visit("http://localhost:3000/");

    cy.get("#error").click();
  });
});

Terminal:

      cy:command ✔  visit       http://localhost:3000/
      cy:command ✔  get #error
      cy:command ✘  click
          cy:xhr ⓘ  GET http://localhost:3000/sockjs-node/info?t=1598261034294
      cons:error ✘  {}
