I struggle to get the code coverage working for all tests in electron, that i wanne use for the gitlab coverage.
Situation
The tests are working and for each test-script I get a nice report.
Same on GitLab pipeline, when i push a commit.
Problem
I can't get a summary coverage report for all the test-scripts I execute.
I use Electron with a frontend which is in another repo.
electron-mocha, chai, sinon for the test and istanbul/nyc for the test-coverage.
Following this Setup TypeScript code coverage for Electron applications.
Test-Scripts
I have multiple test-scripts. One for the main- and two for the renderer process
and run them all with npm test
"coverage": "npm run test && nyc report",
"test": "npm run test-main && npm run test-renderer && npm run test-update-renderer",
"test-main": "electron-mocha --require ts-node/register,babel-register.js \"test/{main,hooks}/**/*.spec.ts\"",
"test-renderer": "electron-mocha --renderer --url src/html/shell.html --require ts-node/register,babel-register.js,src/scripts/preload/shell-preload.ts \"test/{renderer,hooks}/**/*.spec.ts\"",
"test-update-renderer": "electron-mocha --renderer --url src/html/update-dialog.html --require ts-node/register,babel-register.js \"test/{update-renderer,hooks}/**/*.spec.ts\"",
I also have more test-scripts for the pipeline.
.nycrc.json
{
"all": true,
"per-file": false,
"check-coverage": true,
"lines": 70,
"skip-full": false,
"extension": [".ts"],
"include": "src/**/*.ts",
"reporter": ["html", "text", "lcov", "cobertura"]
}

---------------------|---------|----------|---------|---------|------------------------------------------------
main.ts and updater.ts coverage comes from the tests of the electron main process and updater-dialog from the renderer process, which comes from the test scripts test-main and test-update-renderer
Unfortunately in script test-renderer there are two more test-files, which gets executed with green test results, but dont show up in the report.
I tried several things for over a week now but can't get it to work.
If you need more information, please do not hesitate to ask.
