How to run tests from a test-jar in gradle? - java

I have a multi project build in gradle. In project gradle-playground-a I'm creating a test-jar with some junit tests:
plugins {
id 'java'
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.12'
}
repositories {
mavenCentral()
}
test.enabled = false
configurations {
testArtifacts.extendsFrom testRuntime
}
task testJar(type: Jar) {
classifier "test"
from sourceSets.test.output
}
artifacts {
testArtifacts testJar
}
Now I would like to run the tests of the test-jar within another project gradle-playground-b. Therefore I have:
plugins {
id 'java'
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.12'
testRuntimeOnly project (path: ":gradle-playground-a", configuration: 'testArtifacts')
}
repositories {
mavenCentral()
}
However the tests from the test-jar are not run. When I look at gradles debug output I see that the test-jar is included in the classpath for the test execution of gradle-playground-b.
What I'm trying to do is to have an equivalent of mavens surefire depednenciesToScan functionality.
How do I execute the tests from the test-jar when testing gradle-playground-b?

I just use a "button" in netbeans on the first project to activate the second project. That's the only way I really know how to do it because I have done sortof limited projects I am pretty sure you could do this in VB with Visual STudio but since your in Java use netbeans and it's free.

Migrate maven dependencies to gradle

I start with software testing - using Cucumber, Java, gradle.
I try to learn this with the book "The Cucumber for Java Book"
But I try to do I with gradle instead of maven... But now I have some problems...
I stick on page 149. I have to give so dependecies:
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-webapp</artifactId>
<version>${jetty.version}</version>
</dependency>
I try to "translate" this to gradle
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.12'
testCompile 'io.cucumber:cucumber-java:2.4.0'
testCompile 'io.cucumber:cucumber-junit:2.4.0'
testCompile group: 'info.cukes', name: 'cucumber-picocontainer', version: '1.2.5'
compile group: 'org.eclipse.jetty', name: 'jetty-webapp', version: '9.4.12.v20180830'
}
Is this right?
compile group: 'org.eclipse.jetty', name: 'jetty-webapp', version: '9.4.12.v20180830'
After that I have to run:
mvn exec:java -Dexec.mainClass="nicebank.AtmServer"
But how can I do this with gradle?
I hope someone can help me :)
Your dependency looks good. Just one note: consider using implementation over compile as it improves the performance. Read about compile deprecation here.
You can also put your properties in gradle.properties file and reference them in the build script:
gradle.properties:
jettyVersion=9.4.12.v20180830
build.gradle:
implementation group: 'org.eclipse.jetty', name: 'jetty-webapp', version: jettyVersion
Jetty team also published BOMs: — org.eclipse.jetty:jetty-bom:9.4.12.v20180830 in your case. If you use multiple projects of the same version you can import the BOM and skip the version completely:
dependencies {
implementation 'org.eclipse.jetty:jetty-bom:9.4.12.v20180830'
implementation 'org.eclipse.jetty:jetty-webapp'
implementation 'org.eclipse.jetty:jetty-runner'
}
As for the "exec" task: if you have only one main class in your project, like nicebank.AtmServer, consider using Gradle's Application Plugin:
plugins {
id 'application'
}
mainClassName = 'nicebank.AtmServer'
This way you don't need to create "exec" task manually, you'll get one (run) from the plugin. As a bonus you'll get two "distribution" tasks that will create a ready-for-distribution archive with your app: distZip and distTar.
As I said in my comment, the dependency for jetty-webapp seems OK but you should use implementation instead of compile ( compile has been deprecated, see Java dependency configurations):
implementation group: 'org.eclipse.jetty', name: 'jetty-webapp', version: '9.4.12.v20180830'
or
implementation "org.eclipse.jetty:jetty-webapp:9.4.12.v20180830"
For the equivalent of "maven exec:java" in Gradle , you could use the Gradle JavaExec task type: try to define a task in your build as follows:
task runApp(type: JavaExec) {
classpath = sourceSets.main.runtimeClasspath
main = 'nicebank.AtmServer'
}
(not tested, you migth have to adapt it) , and run it with
gradle runApp
You could alternatively use Gretty plugin to run your webapp (no need to define your own JavaExec task in this case), as documented here and here:
plugins{
// your existing plugins
id "org.gretty" version "2.2.0"
}
You can then run the application with:
gradle appRun

How to use jUnit 5 with Gradle

Running the IDEA IDE I want to add a gradle dependency for the jUnit v5.
Here is my build.gradle file, I used this answer as a guide.
apply plugin: 'java'
sourceCompatibility = 1.8
repositories { mavenCentral() }
apply plugin: 'org.junit.platform.gradle.plugin'
dependencies {
testCompile 'junit:junit:4.12'
compile 'junit:junit:4.12'
testRuntime("org.junit.vintage:junit-vintage-engine:4.12.0-M4")
testCompile("org.junit.jupiter:junit-jupiter-api:5.0.0-M4")
testRuntime("org.junit.jupiter:junit-jupiter-engine:5.0.0-M4")
// Enable use of the JUnitPlatform Runner within the IDE
testCompile("org.junit.platform:junit-platform-runner:1.0.0-M4")
compile ("org.junit.jupiter:junit-jupiter-api:5.0.0-M4")
}
sourceSets {
main {
java {
srcDir 'src'
}
}
}
junitPlatform {
details 'tree'
}
The problem here is that the jUnit4 annotations are resolved by import but all the v5 annotations are not resolved.
One example:
#ParameterizedTest
public void testExample() {
// My annotations is not resolved
}
What is the right way to add a jUnit5 dependency using gradle?
EDIT
I started a new gradle java project from scratch to get to the bottom of this.
Here is my current build.gradle.
group 'com.iay0361'
version '1.0-SNAPSHOT'
apply plugin: 'java'
sourceCompatibility = 1.8
repositories { mavenCentral() }
apply plugin: 'org.junit.platform.gradle.plugin'
dependencies {
testCompile group: 'org.junit.vintage', name: 'junit-vintage-engine', version: '4.12.0-RC3'
testCompile group: 'org.junit.jupiter', name: 'junit-jupiter-api', version: '5.0.0-RC3'
testCompile group: 'org.junit.jupiter', name: 'junit-jupiter-engine', version: '5.0.0-RC3'
compile group: 'org.junit.jupiter', name: 'junit-jupiter-params', version: '5.0.0-RC3'
testCompile group: 'org.junit.platform', name: 'junit-platform-runner', version: '1.0.0-RC3'
}
sourceSets {
main {
java {
srcDir 'src'
}
}
}
junitPlatform {
details 'tree'
}
I wrote the #Test annotation in a new class file under test after which it asked me to "add the 'jUnit5' to classpath
which I did and this time selected the Copy 'jUnit5' libraries to... instead of using the IDEA distributor.
Now it added these files in module:
The file is still RC2 but in build.gradle it is RC3.
There are also no jUnit jars in "External Library" directory
What am I missing, the problem is still that the IDE cannot resolve some jUnit5 annotations like #ParamiterizedTest.
Here is a quick sample on how to configure gradle with junit5. In your dependencies, remove the compile statement for the junit:4.12 artifact verison.
// If you also want to support JUnit 3 and JUnit 4 tests
testCompile("junit:junit:4.12")
In the buildscript() method, include these:
buildscript {
repositories { mavenCentral() }
dependencies { classpath 'org.junit.platform:junit-platform-gradle-plugin:1.0.0-RC3' }
}

Gradle can't find package in dependent test project

I'm trying to run ./gradlew build for a nested multi project structure and I'm running into issues that only seem to appear for projects with test source roots. Being new to both java and gradle I'm sure I'm breaking more than one convention, but I still think this should be working.
Essentially, all the dependencies seem to be added fine, but when I have one project that only has a Test srcDir that depends on another project that has a Test srcDir, it doesn't recognize packages/symbols in that root project. However, projects with regular srcDirs (not test) don't seem to have a problem.
My project has more going on than this, but here is the simplest setup I've tried that illustrates the problem.
My project structure:
qatests
/Applications
/AppGroupName
/AppBasePageObjects
/src
/AppBaseTests
/src
/BasePageObjects
/src
/BaseTests
/src
My settings.gradle in qatests:
rootProject.name = 'QaTests'
include 'BasePageObjects'
include 'BaseTests'
include 'Applications:AppGroupName'
include 'Applications:AppGroupName:AppBasePageObjects'
include 'Applications:AppGroupName:AppBaseTests'
My build.gradle in qatests:
version '1.0-SNAPSHOT'
allprojects {
repositories {
mavenCentral()
}
}
subprojects{
if(project.name.contains("Tests")){
apply plugin: 'java'
sourceCompatibility = 1.8
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.11'
compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '2.+'
}
if(project.name != "BaseTests")
{
println "$project.name depends on BaseTests"
dependencies {
testCompile project(':BaseTests')
}
}
sourceSets {
test {
java {
srcDir 'src'
}
}
}
}
if(project.name.contains("PageObjects")){
apply plugin: 'java'
sourceCompatibility = 1.8
dependencies {
compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '2.+'
}
if(project.name !="BasePageObjects")
{
dependencies {
compile project(':BasePageObjects')
}
}
sourceSets {
main {
java {
srcDir 'src'
}
}
}
}
}
I won't include my build.grade for the BaseTest project since that seems to compile fine during the gradlew build, but here is my build.gradle for AppBaseTests:
version '1.0-SNAPSHOT'
dependencies {
compile 'org.apache.commons:commons-lang3:3.4'
compile project(':Applications:AppGroupName:AppBasePageObjects')
}
When I run ./gradlew build in the qatests root, the BaseTests, BasePageObjects, and AppBasePageObjects projects seem to compile fine and AppBasePageObjects successfully uses packages and symbols from BasePageObjects. For some reason however, AppBaseTests can't seem to recognize packages and symbols in BaseTests.
If I clone this project from scratch, IntelliJ runs the gradle scripts scripts automatically and everything seems to work out of the box just fine with the dependencies, so this just confuses me even more.
I've tried adding compile and testcompile for all the project dependencies since that's the only real difference between AppBasePageObjects which works and AppBaseTests which doesn't work. I've also tried adding compileJava.dependsOn(':BaseTests:build') to the AppBaseTests build.gradle file. And a few other rabbit holes, but nothing seems to have any effect on this dependency issue.
For what it's worth, here is the first error I see in the actual build:
error: package Tests does not exist import Tests.BaseTest;
Any help or suggestions are greatly appreciated. If you would like to distribute some harsh insults I'll take those as well. Thank you.
I believe I found an answer while reading another solution here:
Multi-project test dependencies with gradle
It seems I needed to use testCompile project(':BaseTests').sourceSets.test.output for command line builds as well as testCompile project(':BaseTests') for IDE functionality in my root build.gradle file. This only seems to be required for the test projects.
Here are the actual changes in my root build.gradle file:
if(project.name != "BaseTests")
{
println "$project.name depends on BaseTests"
dependencies {
testCompile project(':BaseTests')
testCompile project(':BaseTests').sourceSets.test.output
}
}
This seems a bit hacky but works, if somebody has a more thorough and intelligent answer please post!

How to get gradle and cucumber working together?

Getting gradle to work with cucumber cleanly is something of a challenge. I want to get gradle build to compile and run the tests, but so far I've had no success.
build.gradle
plugins {
id "com.github.samueltbrown.cucumber" version "0.9"
}
apply plugin: 'java'
apply plugin: 'idea'
def JAVA_WEBSOCKET_VERSION = '1.2.1'
def CUCUMBER_VERSION = '1.2.4'
jar {
manifest {
attributes 'Implementation-Title': 'Java-WebSocket',
'Implementation-Version': JAVA_WEBSOCKET_VERSION
}
}
repositories {
jcenter()
}
dependencies {
testCompile "info.cukes:cucumber-java:$CUCUMBER_VERSION"
testCompile "info.cukes:cucumber-junit:$CUCUMBER_VERSION"
testCompile 'junit:junit:4.+'
}
task wrapper(type: Wrapper) {
gradleVersion = '2.9'
}
Currently I get many errors about the annotations (#Given, #Then, #After) that cucumber uses. What I want is to build the project cleanly without using JavaExec. Is this possible or is there a specific limitation to either gradle or cucumber that prevents this?
dependencies {
testCompile 'info.cukes:cucumber-jvm:1+'
testCompile 'info.cukes:cucumber-jvm-deps:1+'
testCompile 'info.cukes:cucumber-java:1+'
testCompile 'info.cukes:cucumber-junit:1+'
testCompile 'info.cukes:cucumber-core:1+'
}
I created another function to execute test
test {
ignoreFailures = true
// show standard out and standard error of the test JVM(s) on the console
testLogging.showStandardStreams = true
// set heap size for the test JVM(s)
minHeapSize = "128m"
maxHeapSize = "512m"
// set JVM arguments for the test JVM(s)
jvmArgs '-XX:MaxPermSize=256m'
// listen to events in the test execution lifecycle
beforeTest { descriptor ->
logger.lifecycle("Running test: " + descriptor)
}
// explicitly include or exclude tests( Add Package directly)
exclude "com/**/***/rest/junit**"
exclude "com/**/***/db/junit**"
reports.junitXml.enabled = false
reports.html.enabled = false
}
now Call this function from command line for test execution
task "forceTest" {
dependsOn "clean", "cleanTest", "test"
}
Please use the below gradle cucumber plugin in your build.gradle file
plugins {
id 'java'
id "com.github.samueltbrown.cucumber" version "0.9"
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.11'
compile 'org.codehaus.groovy:groovy:2.4.7'
cucumberCompile 'info.cukes:cucumber-groovy:1.2.2'
}
Running gradle cucumber in the terminal will get you started

How do you build a .jar that contains external .jar dependencies?

I'm using the Microsoft JDBC Driver 4.1 to connect to SQL Server. In Eclipse I have added the .jar file to the class path of my project ( C:\Program Files\Microsoft JDBC Driver 4.1 for SQL Server\sqljdbc_4.1\enu\sqljdbc41.jar).
I've added this .jar to a folder called lib in my project and am trying to have this .jar added as part of my .jar:
repositories {
mavenCentral()
}
dependencies {
compile files('lib/sqljdbc41.jar')
testCompile group: 'junit', name: 'junit', version: '4.+'
}
However, sqljdbc41.jar is not included in my .jar. Am I missing something?
You have to create a (application) distribution to package your libraries and application jar in a folder: http://gradle.org/docs/current/userguide/application_plugin.html
Alternatively you can use a plugin like https://github.com/johnrengelman/shadow to create a self-contained uberjar.
Thanks chromanoid. I was able to solve the problem two ways. First I placed the sqljdbc41.jar in a new folder called lib in my project. Solution 1 was to create an application distribution:
apply plugin:'application'
apply plugin: 'java'
mainClassName = "main.java.application.Main"
repositories {
mavenCentral()
}
dependencies {
runtime files('lib/sqljdbc41.jar')
testCompile group: 'junit', name: 'junit', version: '4.+'
}
You can then create a distribution using the distZip task. Solution 2 was to create a fat jar.
apply plugin: 'java'
repositories {
mavenCentral()
}
configurations {
provided
compile.extendsFrom provided
}
dependencies {
runtime files('lib/sqljdbc41.jar')
testCompile group: 'junit', name: 'junit', version: '4.+'
}
jar {
dependsOn configurations.runtime
from {
(configurations.runtime - configurations.provided).collect {
it.isDirectory() ? it : zipTree(it)
}
} {
exclude "META-INF/*.SF"
exclude "META-INF/*.DSA"
exclude "META-INF/*.RSA"
}
}
and use the build task.
