Disclamer: clearly this could (and should) be done in a unit-test, but it’s created as a minimum example, as I’m struggling with the complete basics of how to reference a class from an integration test. The example in the plugin tutorials simply references the boilerplate test already present, and event the part about adding a “traditional integration test” simply does a println and an bogus assert.
To create the minimum example, I’ve created a new plugin with atlas-create-jira-plugin.
I have this basic class: HelperClass containing:
package com.nicolaj.cat.impl;
public class HelperClass {
private String name;
public HelperClass(String name) {
this.name = name;
}
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
}
I would like to write a test for this that sets a state, reads it, changes the state and validates that the state has been changed. HelperClassTest contains:
package it.com.nicolaj.cat;
import com.atlassian.plugins.osgi.test.AtlassianPluginsTestRunner;
import com.nicolaj.cat.impl.HelperClass;
import org.junit.Test;
import org.junit.runner.RunWith;
import static org.junit.Assert.assertFalse;
@RunWith(AtlassianPluginsTestRunner.class)
public class HelperClassTest {
@Test
public void someTest()
{
// Arrange
HelperClass hc = new HelperClass("somestring");
String before = hc.getName();
// Act
hc.setName("newstring");
String after = hc.getName();
// Assert
assertFalse("The name hasn't changed!", before.equals(after));
}
}
If I just run atlas-integration-test, I get an error NoClassDefFoundError for HelperClass. On Google I found the article: NoClassDefFoundError. It says to “make sure the class and package name are correct and that the class is declared as a component in its atlassian-plugin.xml .”
- The class and package name is correct. The class is called
HelperClassand it’s in the packagecom.nicolaj.cat.implwhich is imported withimport com.nicolaj.cat.impl.HelperClass;. - When I add it as a component in
atlassian-plugin.xmllike below: (fullatlassian-plugin.xml-file in the bottom)
...
<component key="helperClass" class="com.nicolaj.cat.impl.HelperClass" />
...
however, I get another error:
...
No tests found in class [it.com.nicolaj.cat.HelperClassTest]: No tests found in class [it.com.nicolaj.cat.HelperClassTest]

With the stack trace:

My atlassian-plugin.xml-file looks like this:
<atlassian-plugin key="${project.groupId}.${project.artifactId}-tests" name="${project.name}" plugins-version="2">
<plugin-info>
<description>${project.description}</description>
<version>${project.version}</version>
<vendor name="${project.organization.name}" url="${project.organization.url}" />
</plugin-info>
<!-- from our base plugin -->
<component-import key="myComponent" interface="com.nicolaj.cat.api.MyPluginComponent"/>
<!-- from the product container -->
<component-import key="applicationProperties" interface="com.atlassian.sal.api.ApplicationProperties" />
<component key="helperClass" class="com.nicolaj.cat.impl.HelperClass" />
</atlassian-plugin>
And my project structure looks like this:
Any advice would be helpful.
PS: I know that the above test should just be a unit-test, but it’s created as a minimum example of “an integration test that is not being picked up by junit.”
