Elliotte Rusty Harold resolved MPLUGINTESTING-45.
-------------------------------------------------
Resolution: Cannot Reproduce
> Use of MojoRule causes Guice injection error
> --------------------------------------------
>
> Key: MPLUGINTESTING-45
> URL: https://issues.apache.org/jira/browse/MPLUGINTESTING-45
> Project: Maven Plugin Testing
> Issue Type: Bug
> Reporter: Samuel James Corbett
> Priority: Major
>
> I'm trying to write some tests for a plugin. I am using:
> * Maven version 3.2.3
> * maven-plugin-testing-harness version 3.2.0
> * JUnit version 4.12
> I'm following the instructions at
> http://maven.apache.org/plugin-testing/maven-plugin-testing-harness/getting-started/index.html
> that may or may not be out of date.
> Any use of the {{MojoRule}} class causes all tests to fail with a Guice
> injection error.
> For example, this useless class:
> {code}
> package io.brooklyn.maven;
> import org.apache.maven.plugin.testing.MojoRule;
> import org.junit.Rule;
> import org.junit.Test;
> public class FakeTest {
> @Rule
> public MojoRule mojoRule = new MojoRule() {
> @Override
> protected void after() {
> super.after();
> }
> @Override
> protected void before() throws Throwable {
> super.before();
> }
> };
> @Test
> public void testNothing() {
> }
> }
> {code}
> fails with:
> {code}
> Running io.brooklyn.maven.FakeTest
> Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.04 sec <<<
> FAILURE!
> testNothing(io.brooklyn.maven.FakeTest) Time elapsed: 0.934 sec <<< ERROR!
