How to catch test failure in Selenium Webdriver using JUnit4? - selenium

Question

I need to write the testcase Pass/Fail status in an Excel report. How do I catch the result in a simple way? In Ant XML/HTML reports status (Success/Failed) is displayed so I believe there must be some way to catch this..may be in the #After Class.
Can anyone help me out with this?
I am using Selenium Webdriver with JUnit4 and using Apache POI(oh its screwing my mind too!) for excel handling. Let me know in case you need more info.
Thanks :)
P.S: As I am asking a lot of questions it would be great if someone can change or suggest me changes to make these questions and threads helpful for others.

Answer 1

I got your problem and this is what I have do in all my test cases now -
In your test case if you want to check if 2 Strings are equal -
You might be using this code -
Assert.assertTrue(value1.equals(value2));
And if these values are not equal an AssertionError is generated.
Instead you can change your code like this -
String testCaseStatus = "";
if(value1.equals(value2)){
testCaseStatus = "success";
}
else{
testCaseStatus = "fail";
}
Now you store this result in your excel sheet by passing the testCaseStatus to your code which adds a line to your excel which you have implemented using Apache POI. You can also handle the conditions of "error" if you implement a try catch block.
For example you can catch some exception and add the status as error to your excel sheet.
Edited part of answer -
I just figured out on how to use the TestResult class -
This is some sample code I'm posting -
This is the test case class called ExampleTest -
public class ExampleTest implements junit.framework.Test {
#Before
public void setUp() throws Exception {
}
#After
public void tearDown() throws Exception {
}
#Test
public void test(TestResult result) {
try{
Assert.assertEquals("hari", "");
}catch(AssertionFailedError e){
result.addFailure(this, e);
}catch(AssertionError e){
result.addError(this, e);
}
}
#Override
public int countTestCases() {
// TODO Auto-generated method stub
return 0;
}
#Override
public void run(TestResult result) {
test(result);
}
}
I call the above test case from this code -
public class Test {
public static void main(String[] args) {
TestResult result = new TestResult();
TestSuite suite = new TestSuite();
suite.addTest(new ExampleTest());
suite.run(result);
System.out.println(result.errorCount());
}
}
You can call many test cases by just adding them to this suite and then get the entire result using the TestResult class failures() and errors() methods.
