Ignore Assertion failure in a testcase (JUnit)

Currently, I am writing the automation testing using java and selenium rc.

I would like to verify all the contents present on the user interface, the function is ie below:

public String UITest() throws IOException {

    String result="Test Start<br />";

    try {
        openfile(1);
        for (String url : uiMaps.keySet()) {
            selenium.open(url);
            for (String item : uiMaps.get(url)) {                   
                assertEquals(url+" check: " + item, true,selenium.isTextPresent(item));
                result+=url+" check: " + item+" : OK<br />";
            }
        }
    } catch (AssertionError e) {
        result+=e.getMessage();
    }
    result+="Test finished<br />";
    return result;
}

The function is supposed to return a String containing information about the testing. However, the function stopped once an assertion error happened.

Is there a way to ignore the failure and keep executing all the assertion verifications?

Answer

You could use a JUnit 4 error collector rule:

The ErrorCollector rule allows execution of a test to continue after the first problem is found (for example, to collect all the incorrect rows in a table, and report them all at once)

For example you can write a test like this.

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

  @Test
  public void example() {
    String x = [..]
    collector.checkThat(x, not(containsString("a")));
    collector.checkThat(y, containsString("b"));             
  }
}

The error collector uses hamcrest Matchers. Depending on your preferences this is positive or not.
