junit-clptr

ClassLoader per Test runner for JUnit 4.12+ based on myfaces-test "TestPerClassLoaderRunner".

Each test method will run with its very own ClassLoader which can be very useful for a variety of use cases (testing classes with static fields for example).

Maven dependency

<dependency>
  <groupId>org.bitstrings.test</groupId>
  <artifactId>junit-clptr</artifactId>
  <version>1.2.2</version>
</dependency>

Usage

import org.bitstrings.test.junit.runner.ClassLoaderPerTestRunner;

@RunWith( ClassLoaderPerTestRunner.class )
public class Test
{
  ...
}

Exclude classes using @ClptrExclude annotation

You can exclude a package or a specific class.

@RunWith( ClassLoaderPerTestRunner.class )
@ClptrExclude( "mockit." )
public class Test
{
    ...
}

@RunWith( ClassLoaderPerTestRunner.class )
@ClptrExclude( { "mockit.", "org.somethings.MyClass" } )
public class Test
{
    ...
}

You may use @ClptrExclude on classes and methods.

Globally exclude classes from isolation using file

Use the default file clptr-excludes.properties to add excluded packages or classes from isolation.

The file should be on the classpath.

You can override the excludes file location using the system property org.bitstrings.test.junit.runner.TestClassLoader.excludes.

org.bitstrings.test.junit.runner.TestClassLoader.excludes=com/company/res/clptr-excludes.properties

The file is simply a list of packages and classes (see @ClptrExclude):

jmockit.
org.apache.
com.company.test.TestClass

What's new

• @ClptrExclude annotation;
• Fix for "@Rule" annotated field and method;
• Threadsafe (Hopeful...);
• Support excludes.
