How to print the number of failures for every test case using SoftAssert in TestNG - testing

Question

I have a test case that performs the following:
#Test
public void testNumber() {
SoftAssert softAssert = new SoftAssert();
List<Integer> nums = Arrays.asList(1,2,3,4,5,6,7,8,9,10);
for (Integer num : nums){
softAssert.assertTrue(num%2==0, String.format("\n Old num : %d", num);
}
softAssert.assertAll();
}
The above test will fail for numbers 1,3,5,7,9
Five statements will be printed in the test report.
If I run the test for a larger data set, I find it difficult to get the count of test data that failed the test case.
Is there any easier way to get the number of test data that failed for a test case using softAssert itself ?

Answer 1

Easy way to find count of test data that failed the test case in SoftAssert itself is not possible.
Alternatively you can think of extending Assertion class. Below is the sample that gives count of test data that failed the test case and prints each failure in new line.
package yourpackage;
import java.util.Map;
import org.testng.asserts.Assertion;
import org.testng.asserts.IAssert;
import org.testng.collections.Maps;
public class AssertionExtn extends Assertion {
private final Map<AssertionError, IAssert> m_errors;
public AssertionExtn(){
this.m_errors = Maps.newLinkedHashMap();
}
protected void doAssert(IAssert a) {
onBeforeAssert(a);
try {
a.doAssert();
onAssertSuccess(a);
} catch (AssertionError ex) {
onAssertFailure(a, ex);
this.m_errors.put(ex, a);
} finally {
onAfterAssert(a);
}
}
public void assertAll() {
if (!(this.m_errors.isEmpty())) {
StringBuilder sb = new StringBuilder("Total assertion failed: "+m_errors.size());
sb.append("\n\t");
sb.append("The following asserts failed:");
boolean first = true;
for (Map.Entry ae : this.m_errors.entrySet()) {
if (first)
first = false;
else {
sb.append(",");
}
sb.append("\n\t");
sb.append(((AssertionError)ae.getKey()).getMessage());
}
throw new AssertionError(sb.toString());
}
}
}
You can use this as:
#Test
public void test()
{
AssertionExtn asert=new AssertionExtn();
asert.assertEquals(false, true,"failed");
asert.assertEquals(false, false,"passed");
asert.assertEquals(0, 1,"brokedown");
asert.assertAll();
}
