So. I am trying to get my head around why this isn't working.
I am writing source and test TypeScript code in files in the src and tests directory. These are *.ts and *.spec.ts files.
I use npx tsc to transpile both the source and test files to the directory build. So this directory now contains *.js., *.spec.js, *.js.map and *.spec.js.map file types.
How do I setup mocha and nyc to work with this now?
I have the following set.
.nycrc.json
{
"extends": "@istanbuljs/nyc-config-typescript",
"all": true,
"branches": 0,
"lines": 0,
"functions": 0,
"statements": 0,
"check-coverage": true,
"exclude": [".ignore", "coverage"],
"report-dir": "./coverage/",
"cache": false,
"source-map": true,
"produce-source-map": true
}
tsconfig.json:
{
"compilerOptions": {
"allowJs": true,
"noImplicitAny": false,
"strictNullChecks": true,
"noImplicitThis": true,
"alwaysStrict": true,
"module": "commonjs",
"target": "es2016",
"lib": ["es2016"],
"moduleResolution": "node",
"types": ["mocha", "node"],
"typeRoots": ["node_modules/@types"],
"sourceMap": true,
"outDir": "./build/",
"skipLibCheck": true,
"removeComments": false
},
"include": ["./**/*.ts", "./**/*.js"]
}
Error:
karl@karl-Dell-Precision-M3800:~/dev/escd$ NODE_ENV=test npx nyc --reporter=html --reporter=text mocha "./build/tests/**/*.js"
mappedCoverage.addStatement is not a function
However if I set all to false in the .nycrc.json file, then it doesn't complain. What's up?
I do not wish to use ts-node or anything similar, I have already transpiled the files.
