#Example of measure code coverage of java app by external manual or automated tests

##Application is simple calculator web-service

###Endpoints

• GET http://hostname:8080/plus?first=1&second=1
• GET http://hostname:8080/minus?first=1&second=1
• GET http://hostname:8080/multiply?first=1&second=1
• GET http://hostname:8080/divide?first=1&second=1
• GET http://hostname:8080/pow?first=1&second=1

##How to measure ###1. Build project in debug mode

bash gradlew clean build -DDEBUG=true

###2. Run java application with attached agent

java -javaagent:build/libs/jacocoagent.jar=destfile=build/jacoco/jacoco.exec,append=false -jar build/libs/coverage-metrics-1.0.jar

###3. Execute some endpoints just opening urls in browser

• http://localhost:8080/plus?first=1&second=1
• http://localhost:8080/minus?first=1&second=1

###4. Stop application

###5. Run gradle task to build report

bash gradlew jacocoTestReport

###6. See report in build/reports/jcc/html/index.html
