-----------------------------------
Summary: Override default jUnit tests runner so as not to create a
new instance for each executed test method
Key: SSHD-764
URL: https://issues.apache.org/jira/browse/SSHD-764
Project: MINA SSHD
Issue Type: Improvement
Affects Versions: 1.7.0
Reporter: Goldstein Lyor
Assignee: Goldstein Lyor
The default tests runner (if not specified) is {{BlockJUnit4ClassRunner}} its
default behavior is to create a new instance of the test class for *each
executed test method*. This can be changed by deriving an
{{ExtendedBlockJUnit4ClassRunner}} and overriding its _createTest_ method:
{code:java}
public class ExtendedBlockJUnit4ClassRunner {
private final AtomicReference<Pair<Class<?>, Object>> testHolder = new
AtomicReference<>();
protected Object createTest() throws Exception {
Pair<Class<?>, Object> lastTest = testHolder.get();
Class<?> lastTestClass = (lastTest == null) ? null : lastTest.getLeft();
TestClass curTest = getTestClass():
Class<?> curTestClass = curTest.getJavaClass():
if (curTestClass == lastTestClass) {
return lastTest.getRight();
}
Object instance = curTest.getOnlyConstructor().newInstance();
testHolder.set(Pair.of(curTestClass, instance));
return instance;
}
{code}
