How to use Retry rule along with Errorcollector rule in junit - junit4

Question

I am using Error collector rule in my application( selenium web driver). I am able to thrown exception and continue next line of code with help of error collector rule. But right now i want to re run failed test again ( 3 times) to ensure they are really failed. hence i am using Retry rule. But this rule when applied individually it get executed ( Retry rule with Assert command) `but when written with error collector is doesn't get executed any reason....
Please help me with sample code.
TestBase.java:
public class TestBase {
#Rule
public ErrorCollector collector = new ErrorCollector();
private boolean fatal;
public TestBase() {
fatal=true;
}
public void assertEquals( String msg, Object expected, Object actual) {
if(getFatal()) {
Assert.assertEquals(msg,expected, actual);
} else {
collector.checkThat(msg, actual, CoreMatchers.is(expected));
}
}
public void setFatal(boolean fatalFlag) {
fatal = fatalFlag;
}
public boolean getFatal() {
return fatal;
}
}
BFMNew.java
public class BFMNew extends TestBase {
#Rule
public Retry retry = new Retry(3);
#Rule
public ErrorCollector errocol = new ErrorCollector();
#Before
public void setUp() throws Exception {
System.out.println(" in before");
}
// ===========Re run fail test custom====
public class Retry implements TestRule {
private int retryCount;
public Retry(int retryCount) {
this.retryCount = retryCount;
}
public Statement apply(Statement base, Description description) {
return statement(base, description);
}
private Statement statement(final Statement base,
final Description description) {
return new Statement() {
#Override
public void evaluate() throws Throwable {
Throwable caughtThrowable = null;
// implement retry logic here
for (int i = 0; i < retryCount; i++) {
try {
base.evaluate();
return;
} catch (Throwable t) {
caughtThrowable = t;
System.err.println(description.getDisplayName()
+ ": run " + (i + 1) + " failed");
}
}
System.err.println(description.getDisplayName()
+ ": giving up after " + retryCount + " failures");
throw caughtThrowable;
}
};
}
}
#Test
public void one() {
setFatal(false);
Boolean IsLogin = true; //Here function will come for login
Boolean IsPost = null;
Boolean IsStnComment = null;
Boolean IsPhotoUpload = false;
if( IsLogin ) {
IsPost = false;
assertEquals("Failed to Insert Post", true, IsPost);
}
System.out.println(" After Post ");
assertEquals("Failed to upload photo", true, IsPhotoUpload);
if( IsPost ) {
IsStnComment = false;
//assertEquals("Failed to Insert Comment", true, IsStnComment);
}
System.out.println("After comment");
}

The problem is with rules ordering. You should make ErrorCollector to be outer rule and Retry inner rule. Starting from junit 4.10 use this
class YourTest {
private ErrorCollector collector = new ErrorCollector();
private Retry retry = Retry(3);
#Rule
public TestRule chain= RuleChain
.outerRule(collector)
.around(retry);
// tests using collector go here
}
