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.

Test-Rummer	Plugin	Description	Deprecated
WDIO	wdio-coverage-service	not needed if you don't care about baseline
Uiveri5		TO MY KNOWLEDGE NOT EXISTING	⚠️
Karma	karma-coverage	Test runner used by OPA	⚠️

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/]
			}
		}]
	],
