Unable to save HAR file when a `CypressError` is raised during the test

[gavinhenderson]

This spec DOES NOT generate a har file when run.

describe("Smoke", () => {
  beforeEach(() => {
    cy.recordHar();
  });

  afterEach(() => {
    cy.saveHar({ fileName: "smoke.har" });
  });

  it(["pre-deploy"], "loads the webpage without any issues", () => {
    cy.visit("https://website-that-doesnt-exist.com");
  });
});

I would expect the above spec to fail because it will get an ENOTFOUND error, however I would still like a HAR file in this case.

If you tweak it to this then it does generate a HAR file.

describe("Smoke", () => {
  beforeEach(() => {
    cy.recordHar();
  });

  afterEach(() => {
    cy.saveHar({ fileName: "smoke.har" });
  });

  it(["pre-deploy"], "loads the webpage without any issues", () => {
    cy.visit("https://google.com");
  });
});

If you make the version pointing to a valid website fail in a different way then it will still generate a HAR file. For example, this fails but will still give you a HAR.

describe("Smoke", () => {
  beforeEach(() => {
    cy.recordHar();
  });

  afterEach(() => {
    cy.saveHar({ fileName: "smoke.har" });
  });

  it(["pre-deploy"], "loads the webpage without any issues", () => {
    cy.visit("https://google.com");
    cy.get("body").should("not.exist");
  });
});

Ideally, I would like all three to still generate a HAR file to allow me to debug what is causing the CypressError.
