So far we Seen Many of my previous examples programms in TestNG Framworks,
This Time we are going to take a look on Reports and Assert in TestNG.
TestNG Reporter Logs
TestNG also gives us
the logging facility for the test. For example during the running of test case
user wants some information to be logged in the console. Information could be
any detail depends upon the purpose. Keeping this in mind that we are using
Selenium for testing, we need the information which helps the User to
understand the test steps or any failure during the test case execution. With
the help of TestNG Logs it is possible to enable logging during the Selenium
test case execution.
In selenium there are
two types of logging. High level logging and Low level logging. In low level
logging you try to produce logs for the every step you take or every action you
make in your automation script. In high level logging you just try to capture
main events of your test.
Everybody has their
own style of logging and I have mine too. I am also a big fan of Log4j logging
and that’s why I do not mix log4j logging with testng .
logging but on the same
side I make to use of both of its. I perform low level logging with log4j and
high level logging with testng reporter logs.
How to do it…
1) Write a test case
for Sign In application and implement Log4j logging on every step.
2) Insert Reporter
logs on the main events of the test.

package automationFramework;
import
java.util.concurrent.TimeUnit;
import
org.apache.log4j.Logger;
import org.apache.log4j.xml.DOMConfigurator;
import
org.openqa.selenium.By;
import
org.openqa.selenium.WebDriver;
import
org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Reporter;
import
org.testng.annotations.Test;
import utility.Log;
public class ReporterLogs {
private static WebDriver driver;
private static Logger Log =
Logger.getLogger(Log.class.getName());
@Test
public static void test() {
DOMConfigurator.configure("log4j.xml");
driver = new FirefoxDriver();
Log.info("New driver
instantiated");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Log.info("Implicit wait applied
on the driver for 10 seconds");
driver.get("https://www.facebook.com/");
Log.info("Web application
launched");
// Our first step is complete, so we
produce a main event log here for our reports.
Reporter.log("Application
Lauched successfully | ");
driver.findElement(By.id("email")).sendKeys("yourusername");
Log.info("Username entered in
the Username and email text box");
driver.findElement(By.id("pass")).sendKeys("yourpassword");
Log.info("Password entered in
the Password text box");
driver.findElement(By.id("loginbutton")).click();
Log.info("Click action performed
on Submit button");
// Here we are done with our Second
main event
Reporter.log("Sign In Successful
| " );
driver.quit();
Log.info("Browser closed");
// This is the third main event
Reporter.log("User is Logged out
and Application is closed | ");
}
}
|
3) Run the test by
right click on the test case script and select Run As > TestNG Test.
Your Log4j logging
output will look like this:
But your Reporters log
will look like this:
Log4j logging will
help you to report a bug or steps taken during the test, on the other hand
reporters log will help you to share the test status with leadership. As
leadership is just interested in the test results, not the test steps.
I also use reporter’s
logs on the verification during the test. For example
|
|
if(Text1.equals(Text2)){
Reporter.log("Verification Passed
forText");
}else{
Reporter.log("Verification Failed
for Text");
}
|
TestNG Asserts
TestNG also gives us
the power to take decisions in the middle of the test run with the help of
Asserts. With this we can put various checkpoints in the test. Asserts are the
most popular and frequently used methods while creating Selenium Scripts. In
selenium there will be many situations in the test where you just like to check
the presence of an element. All you need to do is to put an assert statement on
to it to verify its existence.
Different Asserts Statements
1) Assert.assertTrue()
& Assert.assertFalse()

package automationFramework;
import
java.util.concurrent.TimeUnit;
import
org.openqa.selenium.By;
import
org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import
org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import
org.testng.annotations.Test;
public class Asserts {
private static WebDriver driver;
@Test
public void f() {
driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("https://www.facebook.com/");
// Here driver will try to find out My
username textbox on the application
WebElement text_username = driver.findElement(By.id("email"));
//Test will only continue, if the below
statement is true
//This is to check whether the textbox
is displayed or not
Assert.assertTrue(text_username.isDisplayed());
//My username text will be type only if
the above condition is true
myAccount.sendKeys("your_username");
}
}
|
Note: Assert true
statement fails the test and stop the execution of the test, if the actual
output is false. Assert.assertFalse() works opposite of Assert.assertTrue(). It
means that if you want your test to continue only if when some certain element
is not present on the page. You will use Assert false, so it will fail the test
in case of the element present on the page.
2) Assert.assertEquals()
|
|
@Test
public void test() {
String sValue = "Ta bao Lan";
System.out.println(" What is your
full name");
Assert.assertEquals("Ta Bao
Lan", sValue);
System.out.println(sValue);
}
|
It also works the same
way like assert true and assert fail. It will also stop the execution, if the
value is not equal and carry on the execution, if the value is equal.
