Cypress v11 cypress run crashes when assertion in test fails

[niklasvieth]

Current behavior

If an assertion in a test fails by running cypress run --browser chrome the whole process fails instead of showing the result of one failing test in the console as report.
Fails with following error:

u(...).generateDiff is not a function
TypeError: u(...).generateDiff is not a function
    at T.getTestcaseData (<embedded>:1144:21700)
    at T.<anonymous> (<embedded>:1144:19702)

    at process.processTicksAndRejections (node:internal/process/task_queues:78:11)

Desired behavior

Show the failing test result in the report table same as in v10.11

Test code to reproduce

it("Faulty test", () => {
   expect(3).to.equal(4);
}

Same issue here. And I have a strange message at the start:

Couldn't determine Mocha version

[fabian-froehlich]

I am experiencing the same issue when running tests in cli. The cypress GUI runner works as before.

import {defineConfig} from "cypress"

export default defineConfig({
  e2e: {
    baseUrl: "http://localhost:3001"
  },
  reporter: "junit",
  reporterOptions: {
    mochaFile: "cypress/results/junit-report-[hash].xml",
    testCaseSwitchClassnameAndName: true
  },
  video: false,
  viewportHeight: 1080,
  viewportWidth: 1920
})

We experience the same issue, also using "junit" reporter with "mochaFile" option.

Same here, "junit" with "mochaFile"

[cypress-bot]

The code for this is done in cypress-io/cypress#24677, but has yet to be released.
We'll update this issue and reference the changelog when it's released.

Released in 11.1.0.
