Simple UI Testing using TestNG

TestNG is an open-source test automation framework for Java. You can perform various kinds of tests such as unit test, end to end test, integration test, etc. using TestNG.

TestNG - Welcome

Here are some steps to create a TestNG test script:

1. Create Java Project and name it with SampleTestNG

create java project

2. Add some libraries:

a. Add TestNG Library, with step: Click Right on Your Project then Choose Build Path → Choose Add Libraries…

b. Add Selenium Library, with step: Click Right on Your Project then Choose Build Path → Choose Configure Build Path → choose Libraries → choose Add External JARs… → click Apply and Close

selenium library list

• Selenium JAR file (https://www.selenium.dev/downloads/)
• Selenium Standalone server (https://www.selenium.dev/downloads/)

Add Library

Add TestNG Library

3. Add Package com.first.sample under src folder

Create package

4. Create TestNG test script, with step: in com.first.sample package → right click then choose New → choose Other.. → choose TestNG Class → create Class name “search” → click Finish

create TestNG class

create TestNG class

fill Cass name

5. Write test search.java like below.

//search.java
package com.first.sample;
import org.testng.Assert;
import org.testng.annotations.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class search {
public String baseUrl = "https://google.com";
String driverPath = "C:\\webdriver\\chromedriver.exe";
public WebDriver driver ;
@Test
public void searching() {
// launch the chrome browser and open baseUrl
System.out.println("launching chrome browser");
System.setProperty("webdriver.chrome.driver", driverPath);
driver = new ChromeDriver();
driver.get(baseUrl);
// maximize the browser window
driver.manage().window().maximize();
// verify the web title
String expectedTitle = "Google";
String actualTitle = driver.getTitle();
Assert.assertEquals(actualTitle, expectedTitle);
// search cheese
driver.findElement(By.name("q")).sendKeys("cheese" + Keys.ENTER);
// close the web browser
driver.close();
}
}

6. Run Test, with step: Run As → TestNG Test

After running a TestNG project, a test-output folder automatically created in the project structure.

For test report, you can open index.html in test-ouput folder

TestNG report

7. Run All test

To run all your test scripts, you can create testng.xml file in your project, with step: select your project then right click → choose New → choose File and name it with testng.xml

You can runall test scripts based on package like below

<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd" >

<suite name="example suite" verbose="1" >
<test name="Regression suite" >
<packages>
<package name="com.first.sample" />
</packages>
</test>
</suite>

or you can runall test scripts based on class name like below.

<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd" >
<suite name="example suite" verbose="1" >
<test name="Regression suite" >
<classes>
<class name="com.first.example.search"/>
<class name="com.first.example.regexTest"/>
</classes>
</test>
</suite>

testng.xml test result

Note! Eclipse versions for TestNG: 2018–09 (4.9), Photon (4.8), Oxygen (4.7), Neon (4.6), Mars (4.5), Luna (4.4), Kepler (4.3), Juno (4.2, 3.8), Previous to Juno (<=4.1)
