Not able to continue when an Assert condition fails in Selenium Webdriver

Question

I want execution to be continue till end when Assert condition is failing in Selenium WebDriver Script. In my code, when Assert condition fails, it is stopping executing the rest of the code.

Here is code what I wrote. Need help.

try
{
    Assert.assertEquals(false, status);
}
catch(Exception Ex)
{
    System.out.println("Disabled user can register for workshop : case Failed ");
}

Answer 1

Using exceptions to control the flow of logic through code is considered bad practice (you are catching the exception, writing an error message, and continuing processing).

Instead of using assertEquals, you could check the condition directly:

if (status == false) {
    System.out.println("Disabled user can register for workshop : case Failed ");
}

Also, if you still want to print additional information when a test fails (and halt further checks in the test), the Asserts usually provide an overload for optional last parameter to convey such information when the test fails:

Assert.assertEquals(false, status, 
 "Disabled user can register for workshop : case Failed ");

Answer 2

JUnit has a rule called ErrorCollector that can be used to gather progressive stats about a test and report at the end of the execution.

Don't combine Assert and ErrorCollector, you will lose ErrorCollector information if your test fails from an Assert

At the end of your test any failures will be gathered and listed collectively in the JUnit output.

        collector.checkThat(new Object(), IsNull.notNullValue());
        try {
            throw new Exception("Demonstration Exception in collector");
        } catch (Exception ex) {
            collector.addError(ex);
        }
        collector.checkThat("Status does not match!", true, Is.is(true));
        System.out.println("Done.");
    }
    
    /**
     * Test illustrating ErrorCollector behavior when an Assert Fails the Test.
     * 
     */
    @Test
    public void testErrorCollectorWithAssert() {
        collector.checkThat("These things don't match", new Object(), IsEqual.equalTo(new Object()));
        collector.checkThat(new Object(), IsNull.notNullValue());
        try {
            throw new Exception("Demonstration Exception in collector");
        } catch (Exception ex) {
            collector.addError(ex);
        }
        //Test stops here.  You won't see "done", nor will you see any of the previous ErrorCollector status'
        Assert.assertTrue(false);
        
        collector.checkThat("Status does not match!", true, Is.is(true));
        System.out.println("Done.");
    }

}

A Rule must:

• Be annotated with @Rule
• Be declared public in your test.

Proposed Solution:

In the case you list above you should remove the try/catch block and use the Is Matcher instead of org.junit.Assert.assertEquals:

@Rule
public ErrorCollector collector = new ErrorCollector();

@Test
public void testSomething() {
  boolean status = doStatusEval(); 
  collector.checkThat("Disabled user can register for workshop", false, Is.is(status));
 //Continue adding things to the collector.
}

Best of Luck!
