How to run junit tests on a non java project - java

I have a project folder but it is not a java project. It is a maven project. I have written a junit test and it runs perfectly when running in the eclipse IDE but when I run the maven command mvn install, it seems to skip my junit tests. I have included the test file in src/test/java/ (the name of my test is AppTest.java) and the main .java file (with the main method) is in src/main/java/. I have noticed that the project I am currently working on is a maven project and not a maven java project. I have included a screen of my current folder structure:
folder structure
Maven test output <- should not build as I have a deliberate test that should fail
This is the POM. I have deleted/commented out some sensitive parts so the pom file may be syntactically wrong but the main plugins I use are there; tap4j, junit and surefire.

The problem is the packaging of your project which is pom
You can't execute Surefire on this kind of project.

Try adding surefire plugin. When i have tests in my app i always include it (works for junit as well as testng). Based on your logs i can see that you dont have it declared.

Can I use PowerMockito in Quarkus with JUnit5?

Im am currently building a Quarkus application and for unit testing I am using JUnit5. Currently I have no other option then using PowerMockito to mock my static functions but I cant seem to find the dependencies for it in my Quarkus project.
Does anyone know what the best set of dependecies should be used in a Quarkus app for PowerMockito with JUnit5?
I guess you don't need PowerMockito, just the capability to mock static methods. Since 2.7.x (released in 2017) Mockito community made an experimental library called mockito-inline for mocking static methods or final classes. Some features (e.g. static method mocking) have already merged into mockito-core.
Additionally Quarkus has extension for Mockito.
Here is a working example

Cucable Plugin not running Scenarios in parallel

I'm trying to run Scenario's in parallel using Trivago's Cucable Plugin. To test it before implementing it my project I download this project.
https://github.com/trivago/cucable-plugin/tree/master/example-project
I tried, mvn clean verify and it created *IT.java files in target folder, but I noticed these are not running in parallel.
How do I know? I added sleep in each statement. Largest sleep is 15 seconds, so the total build should be approx 16 seconds, but it is showing 30 (sum of all sleeps of all scenarios 2+5+15+8) seconds.
cucable.template
import cucumber.api.CucumberOptions;
import org.junit.runner.RunWith;
#RunWith(Cucumber.class)
#CucumberOptions(
glue = "steps",
features = {"target/parallel/features/[CUCABLE:FEATURE].feature"},
plugin = {"json:target/cucumber-report/[CUCABLE:RUNNER].json"}
)

Key Point :
We shall not mix direct & transitive dependencies specially their versions! Doing so can cause unpredictable outcome.
We would need to use Cucumber-JVM v4.x.x specially to implement parallel execution without using cucumber-jvm-parallel or cucable plugin
We would be considering v4.2.6 for the implementation
Cucumber Parallel Execution via JUnit
First - Update POM.xml with correct set of io.cucumber dependencies.
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-junit</artifactId>
<version>4.2.6</version>
</dependency>
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-picocontainer</artifactId>
<version>4.2.6</version>
</dependency>
Point To Note Down - There could be an issue like everything is ok but still tests do not execute in parallel and could be if your pom.xml is having direct/transitive dependency of testng. As testNG causes Surefire to ignore JUnit wrapper class. If you had testng dependency so remove the TestNG dependency or you can take a call to 2 define 2 execution - For TestNG & JUnit and disable one as per your need.
Second - Customize Runner class as per your framework need
package com.jacksparrow.automation.suite.runner;
import org.junit.runner.RunWith;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
#RunWith(Cucumber.class)
#CucumberOptions(features = "classpath:features/functional/",
glue = {"com.jacksparrow.automation.steps_definitions.functional" },
plugin = { "pretty","json:target/cucumber-json/cucumber.json",
"junit:target/cucumber-reports/Cucumber.xml", "html:target/cucumber-reports"},
tags = { "#BAMS_Submitted_State_Guest_User" },
junit ={ "--step-notifications"},
strict = false,
dryRun = false,
monochrome = true)
public class RunCukeTest {
}
Third - Implementing maven surefire plugin which would actually run tests in parallel
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M3</version>
<configuration>
<parallel>methods</parallel>
<threadCount>2</threadCount>
<reuserForks>false</reuserForks>
<testFailureIgnore>true</testFailureIgnore>
<includes>
<include>**/*RunCukeTest.java</include>
</includes>
</configuration>
</plugin>
Fourth - Implement Hooks.java
import cucumber.api.Scenario;
import cucumber.api.java.Before;
import cucumber.api.java.After;
public class Hooks {
#Before
public void setUpScenario(String browser){
//BaseSteps.getInstance().getBrowserInstantiation(browser); your browser setup method
}
#After
public void afterScenario(Scenario scenario){
// more code goes here
}
}
Cucumber Parallel Execution via TestNG
Note : In below implementation, we would be reading browser parameter from TestNG.xml file
First - Update POM.xml with correct set of io.cucumber dependencies.
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-picocontainer</artifactId>
<version>4.2.6</version>
</dependency>
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-testng</artifactId>
<version>4.2.6</version>
</dependency>
Second - Customize TestNGRunner class as per your framework need
package com.jacksparrow.automation.suite.runner;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Parameters;
import com.jacksparrow.automation.steps_definitions.functional.BaseSteps;
import cucumber.api.CucumberOptions;
import cucumber.api.testng.AbstractTestNGCucumberTests;
#CucumberOptions(features = "classpath:features/functional/",
glue = {"com.jacksparrow.automation.steps_definitions.functional" },
plugin = { "pretty","json:target/cucumber-json/cucumber.json",
"junit:target/cucumber-reports/Cucumber.xml", "html:target/cucumber-reports"},
tags = { "#BAMS_Submitted_State_Guest_User" },
junit ={ "--step-notifications"},
strict = false,
dryRun = false,
monochrome = true)
public class RunCukeTest extends Hooks {
}
Third - Implement Hooks.java
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Parameters;
import cucumber.api.testng.AbstractTestNGCucumberTests;
public class Hooks extends AbstractTestNGCucumberTests {
#Parameters({ "browser" })
#BeforeTest
public void setUpScenario(String browser){
//BaseSteps.getInstance().getBrowserInstantiation(browser); your browser setup method
}
}
Fourth - Update TestNG.xml under /src/test/resources/ as per your TestNGRunner Class and framework need.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Testng Cucumber Suite" parallel="tests" thread-count="2">
<test name="SmokeTest">
<parameter name="browser" value="chrome" />
<classes>
<class name="com.cvs.runner.TestSuiteRunner" />
</classes>
</test>
</suite>
Fifth - You shall be all set to run automation suite using TestNG in any of the following ways
- Run TestNG.xml directly from IDE
- From CMD - mvn test -Dsurefire.suiteXmlFiles=src/test/resources/testng.xml
- From POM.xml - Using Surefire Plugin

using POM to skip mvn integration tests in Eclipse

I have created Tests and IntegrationTests (IT) defined in the POM and classNames which I run from the commandline; I now wish them to run them from Eclipse. Here is the skeleton:
test:
package org.xmlcml.it;
import org.junit.Assert;
import org.junit.Test;
public class SimpleTest {
#Test
public void simpleTest() {
Assert.assertTrue("simpleTest", true);
System.out.println("RAN simpleTest");
}
}
run with:
mvn clean test
and the integration tests:
package org.xmlcml.it;
import org.junit.Test;
import junit.framework.Assert;
public class SimpleIT {
#Test
public void integrationTest() {
Assert.assertTrue("integrationTest", true);
System.out.println("RAN integrationTest");
}
}
run with
mvn clean integration-test
My POM is:

When I run this from Eclipse (4.5.2) the IT tests are run. How can I alter the POM so they are skipped by default (and how can I switch them back on)?
NOTE: I have used
http://maven.apache.org/surefire/maven-failsafe-plugin/usage.html
for guidance but still have problems with the multiple ways of switching tests on and off (#Test, *Test.java, method public void testFoo(), ${skipTests} ...) and some of the SO answers are labelled as obsolete. I am not clear which take precedence - is there an up-to-date cheat sheet?

Unable to run testng annotations in Eclipse

I was trying to understand the working of testng framework by implementing a simple program in Eclipse editor(in ubuntu os). My source code and pom xml are defined as follows:
TestExample.java

import org.testng.annotations.Test;
#Test(suiteName = "test suite for annotation")
public class TestExample {
#BeforeSuite
public void setup() {
System.out.println("before test");
}
#AfterSuite
public void finish() {
System.out.println("After test");
}
#Test(description = "Test to save student", priority = 0)
public void testSaveStudent() {
System.out.println();
System.out.println("Testing.....");
System.out.println();
}
}

Problems testing services created with maven-scr-plugin when using pax-exam

I've set up a very simple "HelloWorld" service to demonstrate my problem. It uses the maven-scr-plugin to generate a service descriptor and has a pax-exam unit test. But when I try to run 'mvn clean test' it blocks for a while before giving me this error:
org.ops4j.pax.swissbox.tracker.ServiceLookupException: gave up waiting for service com.liveops.examples.osgi.helloworld.HelloWorldService
If I run 'mvn -DskipTests=true package' and then run 'mvn test' (without clean)
it works. The difference seems to be the addition of this line in my META-INF/M
ANIFEST.MF file:
Service-Component: OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml
Does anyone know if there is a way to make sure this line is added earlier in the build process so that 'mvn clean test' will pass? Or is there something else I might be doing wrong?
For reference, here is the pom.xml, the service, and the unit test.

HelloWorld Implementation class
package com.liveops.examples.osgi.helloworld.internal;
import com.liveops.examples.osgi.helloworld.HelloWorldService;
import org.apache.felix.scr.annotations.Service;
import org.apache.felix.scr.annotations.Component;
#Component
#Service(HelloWorldService.class)
public class HelloImpl implements HelloWorldService
{
public String helloWorld(String personalization)
{
return "Hello " + personalization + "!";
}
}
The unit test
package com.liveops.examples.osgi.helloworld.internal;
import com.liveops.examples.osgi.helloworld.HelloWorldService;
import junit.framework.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.ops4j.pax.exam.Option;
import org.ops4j.pax.exam.Configuration;
import org.ops4j.pax.exam.junit.PaxExam;
import org.ops4j.pax.exam.util.PathUtils;
import javax.inject.Inject;
import static org.ops4j.pax.exam.CoreOptions.*;
#RunWith(PaxExam.class)
public class HelloImplTest
{
#Inject
HelloWorldService hws;
#Configuration
public static Option[] configuration() throws Exception{
return options(
systemProperty("org.ops4j.pax.logging.DefaultServiceLog.level").value("WARN"),
mavenBundle("org.apache.felix", "org.apache.felix.scr", "1.6.2"),
bundle("reference:file:" + PathUtils.getBaseDir() + "/target/classes"),
junitBundles());
}
#Test
public void testInjection()
{
Assert.assertNotNull(hws);
}
#Test
public void testHelloWorld() throws Exception
{
Assert.assertNotNull(hws);
Assert.assertEquals("Hello UnitTest!", hws.helloWorld("UnitTest"));
}
}
Use the ProbeBuilder to enhance your tested bundle:
#ProbeBuilder
public TestProbeBuilder probeConfiguration(TestProbeBuilder probe) {
probe.setHeader("Service-Component", "OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml");
return probe;
}
This most likely is all that's missing.
EDIT:
just in case you're trying to use pax-exam in the same bundle you need to take certain actions in your configuration method:
streamBundle(bundle()
.add(SomceClass.class).add("OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml", new File("src/main/resources/OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml")
.toURL())
.set("Service-Component", "OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml")
.build()).start()
a complete sample can be found at here
I may have a fix for this, though it seems a bit in-elegant. I can explicitly add the Service-Component to the maven-bundle-plugin section of the pom file.
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.3.7</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.name}</Bundle-SymbolicName>
<Bundle-Version>${project.version}</Bundle-Version>
<Export-Package>!${namespace}.internal.*,${namespace}.*;version="${project.version}"</Export-Package>
<Private-Package>${namespace}.internal.*</Private-Package>
<!--Explicitly add the components no that they can be found in the test phase -->
<Service-Component>OSGI-INF/com.liveops.examples.osgi.helloworld.internal.HelloImpl.xml</Service-Component>
</instructions>
</configuration>
<executions>
<execution>
<id>generate-manifest</id>
<phase>process-classes</phase>
<goals>
<goal>manifest</goal>
</goals>
</execution>
</executions>
</plugin>
Please let me know if anyone can think of a better way.
The Maven SCR Plugin only generates the service component descriptors but it does not include them in the manifest automatically.
So there's nothing inelegant about including a <Service-Component> instruction in the Maven Bundle Plugin configuration, that's just the documented usage.
Since the manifest header is missing, SCR does not register any services on behalf of your bundle, and that's why Pax Exam can't find the required service.
