How to set up sonar to work with jest

pre-requisites:

• node & npm
• java
• cmder or powershell or git bash or equivalent terminal

Download sonarqube server

https://www.sonarqube.org/downloads/

• sonarqube 7.1

Run StartSonar.bat to load server

C:\baps\sonar\sonarqube-7.1\bin\windows-x86-32\StartSonar.bat

Troubleshoot cant find server/

go to java dir:

C:\Program Files (x86)\Java\jre1.8.0_45\bin

• duplicate client/ as server/

open window browser

localhost:9000

login:

• user: admin
• pwd: admin

add token

experiment

select -

• other js
• windows

add project

experiment

copy properties needed from command line

sonar-scanner.bat -Dsonar.projectKey=experiment -Dsonar.sources=. -Dsonar.host.url=http://localhost:9000 -Dsonar.login=b31e38900133da2fabf9d06861cca8965ce1ee6b

create sonar-project.properties local to your project:

sonar.projectKey=experiment
sonar.host.url=http://localhost:9000
sonar.login=b31e38900133da2fabf9d06861cca8965ce1ee6b
sonar.projectName=experiment

sonar.tests=./specs/
sonar.sources=./src/
sonar.testExecutionReportPaths=./reports/test-reporter.xml
sonar.javascript.lcov.reportPaths=./coverage/lcov.info

add this project now into a git repo, otherwise sonarqube scanner will give blame error messages and may not work

$ git init
$ git add .
$ git commit -m"my updated sonar-project.properties file and other stuff"

run npm dependencies

$ npm install

run tests

$ npm run test

Allow firewall and antivirus to let sonar-scanner run

note: it will depend on your sonar-project.properties to work

open sonarqube server in browser

localhost:9000 make sure you can see visible unit tests and coverage with a percentage greater than zero.

troubleshoot coverage not showing anything?

• make sure you have spelt sonar-project.properties paths exactly correct. One letter out and it won't tell give useful debug error messages.

sonar.tests=./specs/
sonar.sources=./src/
sonar.testExecutionReportPaths=./reports/test-reporter.xml
sonar.javascript.lcov.reportPaths=./coverage/lcov.info

note:

• sonar.testExecutionReportPath will not work (You could spend days and hours scratching your head if you miss this)
• sonar.testExecutionReportPaths will work
