Furthermore you can include and/or exclude multiple categories.

Although it extends `WildcardPatternSuite` you are not forced to use a wildcard pattern, you can also list the children class using the `@SuiteClasses` annotation known from JUnit.

In contrast to the `Enclosed` runner provided by JUnit it detects if an inner class is actually a test class and ignores all other inner classes.

If this system property is not set, there will be as many worker threads as the number of processors available to the JVM.

+ * New runner `ParallelInnerTestClassesSuite` which runs all inner test classes of the class annotated with `@RunWith(ParallelInnerTestClassesSuite.class)`. In contrast to the `Enclosed` runner provided by JUnit, it detects if an inner class is actually a test class and ignores all other inner classes. In contrast to `InnerTestClassesSuite` it executes its children classes concurrently using several worker threads. run Example:
+```
+@RunWith(InnerTestClassesSuite.class)
+public class LoginBeanTests {

+    public static class UnitTests {
+        @Test
+        public void test1() { ... }

 ## Version 2.4 (for Java 8) and Version 1.11 (for Java 6) ##
  * [WildcardPatternSuite](//michaeltamm.github.io/junit-toolbox/com/googlecode/junittoolbox/WildcardPatternSuite.html) can now handle wildcard patterns starting with "../" (fixes [#16](https://github.com/MichaelTamm/junit-toolbox/issues/16))
  * Fixed edge case where too many threads were created when using one of [ParallelRunner](//michaeltamm.github.io/junit-toolbox/com/googlecode/junittoolbox/ParallelRunner.html),  [ParallelParameterized](//michaeltamm.github.io/junit-toolbox/com/googlecode/junittoolbox/ParallelParameterized.html), or  [ParallelSuite](//michaeltamm.github.io/junit-toolbox/com/googlecode/junittoolbox/ParallelSuite.html) contributed by Till Klister
