Continuing test execution in junit4 even when one of the asserts fails

java junit4

I have my existing framework built up using Jfunc which provides a facility to continue exection even when one of the asserts in the test case fails. Jfunc uses junit 3.x framework. But now we are migrating to junit4 so I can't use Jfunc anymore and have replaced it with junit 4.10 jar.
Now the problem is since we have extensively used jfunc in our framework, and with junit 4 we want to make our code continue the execution even when one of the asserts fails in a test case.
Does anyone has any suggestion/idea for this, i know in junit the tests needs to be more atomic i.e. one assert per test case but we can't do that in our framework for some reason.

You can do this using an ErrorCollector rule.

To use it, first add the rule as a field in your test class:

public class MyTest {
    @Rule
    public ErrorCollector collector = new ErrorCollector();

    //...tests...
}

Then replace your asserts with calls to collector.checkThat(...).

e.g.

@Test
public void myTest() {
    collector.checkThat("a", equalTo("b"));
    collector.checkThat(1, equalTo(2));
}
