Cypress tests with mocha multi reports; not able to get aggregated results for all test spec

Question

Cypress tests with mocha multi reports don't show results from all the tests

My test structure looks like so:
cypress
 integration
  module1
   module1test1_spec.js
   module1test1_spec.js
  module2
   module2test1_spec.js
   module2test1_spec.js

I have set up Cypress to use mocha-multi-reports like in instruction provided under
https://docs.cypress.io/guides/tooling/reporters.html#Multiple-Reporters
My config.json looks exactly like here:
https://github.com/cypress-io/cypress-example-docker-circle#spec--xml-reports
When Cypress finishes testing, results.xml file shows results from last test spec ONLY; module2test1_spec.js
How to configure this to get the aggregated results from all test spec?

Answer 1

You can use [hash].xml in your path.

e.g. ./path_to_your/test-results.[hash].xml. [hash] is replaced by MD5 hash of test results XML. This enables support of parallel execution of multiple mocha-junit-reporter's writing test results in separate files.

https://www.npmjs.com/package/mocha-junit-reporter#results-report

I solved this problem with this way.

my config.json file seems like this:

"reporterEnabled": "spec,json, mocha-junit-reporter",
  "mochaJunitReporterReporterOptions": {
    "mochaFile": "multiple-results/[hash].xml",

Answer 2

Just to add to the answer above, if you would like to merge all these multiple [hash].xml created into a single mergedreport.xml report, then you can use this package junit-report-merger which is useful for running it on CI pipeline which usually looks for a single reporter with a command like the one below:

jrm ./cypress/reports/mergedreport.xml "./cypress/reports/*.xml"
