Viewing results of junit test for gradle?

Question

So I currently have the following build.gradle file:

apply plugin: 'java'

sourceSets {
    main {
        java {
            srcDir 'src/model'
        }
    }

    test {
        srcDirs = ["tests/model"]
    }
}

dependencies {
    compile files('libs/mnist-tools.jar', 'libs/gson-2.2.4.jar')
    runtime fileTree(dir: 'libs', include: '*.jar')

    testCompile group: 'junit', name: 'junit', version: '4.+'
}  

that builds successfully when I type "gradle test" into the command line.

However I do the following error when running gradle test:

Creating properties on demand(a.k.a dynamic properties) has been deprecated.

As you can see, my junit tests are all in the folder test/model/ but I was wondering how do I see the results of if my junit tests passed?

Chingy,

I had to update a couple of things in your build.gradle:

source set for tests
added Maven repository to get JUnit library

apply plugin: 'java'

repositories {
    mavenCentral()
}

sourceSets {
    main {
        java {
            srcDir 'src/model'
        }
    }

    test {
        java {
            srcDir 'tests/model'
        }
    }
}

dependencies {
    compile files('libs/mnist-tools.jar', 'libs/gson-2.2.4.jar')
    runtime fileTree(dir: 'libs', include: '*.jar')

    testCompile group: 'junit', name: 'junit', version: '4.+'
}

Now, the results of $ gradle build:

bender:WalnutiQ demo$ gradle build
:compileJava UP-TO-DATE
:processResources UP-TO-DATE

I think you can take it from here :o)

PS: I would recommend to refactor your project structure to match Maven/Gradle structure, so you don't have to deal with source sets and it will make your build.gradle cleaner.

src/main/java   Production Java source
src/main/resources  Production resources
src/test/java   Test Java source
src/test/resources  Test resources
src/sourceSet/java  Java source for the given source set
src/sourceSet/resources Resources for the given source set

Answer 2

When you run gradle build or gradle test, there is a build directory that is created. This directory is where all the build artifacts are placed. Inside the build directory is a reports directory. This directory is where reports are placed. For example, pmd reports, junit reports, etc.

The JUnit reports are located in the tests directory. Open up the index.html file in a browser to view the report.

Answer 3

You can specify where the JUnit test results go with the following command within your test block.

test {
    reports.junitXml.destination = file('build/test-results/folder')
}
