Setup test local use

1. Setup path to sync between test and code

• Setup path for source: tsconfig.json

Add this setting to the file to use @src instead of src (the real path)

    "paths": {
      "@src/*": ["src/*"]
    },

full content:

{
  "compilerOptions": {
    "module": "commonjs",
    "declaration": true,
    "removeComments": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "allowSyntheticDefaultImports": true,
    "target": "ES2021",
    "sourceMap": true,
    "outDir": "./dist",
    "baseUrl": "./",
    "paths": {
      "@src/*": ["src/*"]
    },
    "incremental": true,
    "skipLibCheck": true,
    "strictNullChecks": false,
    "noImplicitAny": false,
    "strictBindCallApply": false,
    "forceConsistentCasingInFileNames": false,
    "noFallthroughCasesInSwitch": false
  }
}

• Setup path for test package.json

add this setting to jest configs

    "moduleNameMapper": {
      "^@src/(.*)$": "<rootDir>/$1"
    }

full content:

  "jest": {
    "moduleFileExtensions": [
      "js",
      "json",
      "ts"
    ],
    "rootDir": "src",
    "testRegex": ".*\\.spec\\.ts$",
    "transform": {
      "^.+\\.(t|j)s$": "ts-jest"
    },
    "collectCoverage": true,
    "collectCoverageFrom": [
      "**/*.(t|j)s",
      "!**/*.dto.ts",
      "!**/*.entity.ts",
      "!**/*.mock.ts",
      "!**/*.module.ts",
      "!**/*.repository.ts",
      "!**/*.task.ts",
      "!**/*.old.ts",
      "!**/*.schema.ts",
      "!**/*main.ts"
    ],
    "coverageDirectory": "../coverage",
    "coverageReporters": [
      "json",
      "html"
    ],
    "testEnvironment": "node",
    "moduleNameMapper": {
      "^@src/(.*)$": "<rootDir>/$1"
    }
  }

2. Generate report

• install jest-html-reporter to generate report (seems no need)

• add reporters to jest settings

    "coverageReporters": [
      "json",
      "html"
    ],
