Name of the report is not saving as expected (even though 'reportFilename' in cypress.json file is changed)

i am using mochawesome for my cypress tests.

This is my cypress.json file

{
  "viewportWidth": 1440,
  "viewportHeight": 800,
  "defaultCommandTimeout": 8000,
  "reporter": "mochawesome",
  "reporterOptions": {
      "reportDir": "cypress/reports/mochawesome-report",
      "reportFilename": "sample",
      "overwrite": false,
      "html": true,
      "json": true  
   },
  "env": {
    "environment": "Stagging"
  },
  "screenshotsFolder": "cypress/reports/mochawesome-report/assets",
}

when I ran my tests, the reports are generated with name ‘sample.html’ which is expected as I have defined my report title as sample in cypress.json file.

now I wanted to have unique name for each report generated based on the test suite name.

so I have used the cypress event ‘test:before:run’ and set the reportFilename in cypress.json to the test suite name before the execution of each test, the sample code is down below

Cypress.on("test:before:run", (test, runnable) => {
    console.log(Cypress.config("reporterOptions").reportFilename);
    const suiteTitle = runnable.parent.title;
    Cypress.config({
        "reporterOptions":{
            "reportFilename": suiteTitle
        }
    });
    const reportFileName = Cypress.config("reporterOptions").reportFilename;
    console.log(reportFileName);
});

I see the reportFilename is successfully changed to Tests suite name

But my report is still saved as ‘sample.html’

Why my report is still saving as sample.html , instead of my test suite name?

can you help me to resolve this @adamgruber ?

Looking into this a bit, adding the feature is pretty straightforward but to work with Cypress will require https://github.com/cypress-io/cypress/issues/1495 to be complete.

This will not work because the reporter has already been created with the initial options and no longer references the Cypress config. There is currently no way to have custom filenames for each test.
