ui5-middleware-code-coverage-advanced

A code instrumenter middleware for ui5-server, enabling code coverage on the fly.

• support inline source maps
  • you can debug the instrumented code
• support clean
  • clears .nyc_output on startup
• support baseline
  • creates file in .nyc_output/baseline.json
  • your coverage report contains all js files, not just the one loaded during test

Inspired by ui5-middleware-code-coverage.

Component-preload.js

Component-preload has up to today no source maps. Therefore this plugin supports currently only apps server from the standard folder webapp.

There is no way to map the coverage back the the original source.

Install

npm install ui5-middleware-code-coverage-advanced --save-dev

Usage - UI5-Tooling

1. Define the dependency in $yourApp/package.json:

    "devDependencies": {
        "ui5-middleware-code-coverage-advanced": "*"
    },
    "ui5": {
      "dependencies": [
        "ui5-middleware-code-coverage-advanced"
      ]
    }

2. configure it in $yourApp/ui5.yaml:

    server:
      customMiddleware:
      - name: ui5-middleware-code-coverage-advanced
        afterMiddleware: compression
        mountPath: /
        configuration:
          enabled: true

   Usage - Test-Runner

   Extract the window.__coverage__ during test run with your test-runner.

WDIO

This works now native, no need for any middleware or plugins(but no baseline support), simply do:

services: [
        ["devtools", {
            coverageReporter: {
                enable: true,
                type: "lcov",
                logDir: __dirname + "/coverage",
                exclude: [/resources/]
            }
        }]
    ],
