# Java gradle project with Junit and JaCoCo example
*Pre-requisite: gradle and java is installed on your machine.*
1. Create a gradle project (I used Eclipse IDE)
2. Inside the project you will see two folders **main** and **test** under src folder. Under main you write your development code and under test you write your unit (Junit) tests and integration tests.
3. Add the below lines of code to your **build.gradle** file present in the root directory.
```java
apply plugin: "jacoco"
```
```java
jacocoTestReport{
reports {
xml.enabled false
csv.enabled false
html.destination "${buildDir}/jacocoHtml"
}
}
```
If Junit dependency is not present then add it:
```java
dependencies {
testCompile 'junit:junit:4.12'
}
```
3. Create a **Example.java** class under main folder.
```java
public class Example {
public long someRandomMethod(int a, int b) {
if (a > 10 && b > 10){
return a+b;
}
else{
return a-b;
}
}
}
```
4. To verify this method, we will be writing Junit test under test folder with name **ExampleTest.java**
*@Test* annontation tells Junit that it is a test method to execute.
```java
public class ExampleTest {
@Test
public void verifySomeRandomMethod() {
Example junitTest = new Example();
junitTest.someRandomMethod(11, 12);
}
}
```
5. Go to the root directory of your project. And execute the below command to execute Junit test.
```java
gradle clean test
```
6. Junit results report will be generated /JunitJacocoExample/build/reports/tests/test/classes/ExampleTest.html
7. To generate code coverage report, execute the below command.
```java
gradle jacocoTestReport
```
8. Code coverage report will be generated /JunitJacocoExample/build/jacocoHtml/index.html
Code coverage at class level can be verified by navigating to **Example.java**
