I am trying to mock a public class BuildInfo but Mockito complains that it cannot. I have java 11 JDK installed. The code under test is part of a Jenkins shared library.
Here is what my test class looks like
import org.jfrog.hudson.pipeline.common.types.ArtifactoryServer
import org.jfrog.hudson.pipeline.common.types.buildInfo.BuildInfo
import org.junit.Test
import static org.mockito.Mockito.*
import org.jfrog.hudson.pipeline.scripted.dsl.ArtifactoryPipelineGlobal
class ArtifactoryLib extends BaseTest {
@Override
void setUp() throws Exception {
super.setUp()
ArtifactoryPipelineGlobal artifactory = mock(ArtifactoryPipelineGlobal.class)
when(artifactory.newServer(anyMap())).thenReturn(mock(ArtifactoryServer.class))
when(artifactory.newBuildInfo()).thenReturn(mock(BuildInfo.class))
binding.setVariable("Artifactory", artifactory)
}
@Test
void someTest() {
def server = Artifactory.newServer url:url, credentialsId: credentialsId
binding.getVariable("artifactorylib").doSomething("abc")
}
}
My code under test is doing something like the following:
void upload(String spec, int retention, def server) {
// Artifactory here is of type ArtifactoryPipelineGlobal
def buildInfo = Artifactory.newBuildInfo()
buildInfo.retention([:])
}
void doSomething(String project) {
// Artifactory here is of type ArtifactoryPipelineGlobal
def server = Artifactory.newServer(url:"URL_HERE")
upload("abc", 123, server)
}
My build.gradle looks like following:
import org.gradle.api.tasks.testing.logging.TestExceptionFormat
import org.gradle.api.tasks.testing.logging.TestLogEvent
group 'jenkins-shared-library'
version '1.0-SNAPSHOT'

}
When running the command ./gradlew clean test, I get the following error
Mockito cannot mock this class: class org.jfrog.hudson.pipeline.common.types.buildInfo.BuildInfo.
Mockito can only mock non-private & non-final classes.

Note that mocking both the following mocks work mock(ArtifactoryPipelineGlobal.class) and mock(ArtifactoryServer.class) but not mock(BuildInfo.class)
Turns out I was using the JCenter site for fetching the artifactory dependencies. Once I switched to the JFrog site, all worked well.
