What is TestNG, and how is it different from JUnit?
TestNG is a testing framework inspired by JUnit, but it offers additional features like parallel test execution, flexible test grouping, and better reporting.
How do you annotate a method as a TestNG test method?
Use the @Test annotation, like this:
@Test
public void myTestMethod() {
// Test code here
}
What is the purpose of the @BeforeTest and @AfterTest annotations?
@BeforeTest is used to run setup code before any test method in the test class, and @AfterTest is used to run cleanup code after all test methods in the class.
How do you perform parameterized testing in TestNG?
Use the @DataProvider annotation to supply data to a test method, like this:
java
@DataProvider(name = "myData")
public Object[][] testData() {
return new Object[][] { { 1, 2 }, { 3, 4 } };
}
@Test(dataProvider = "myData")
public void myTestMethod(int a, int b) {
// Test code here using a and b
}
Explain how to enable parallel test execution in TestNG.
Use the parallel attribute in the <suite> tag of your testng.xml file or annotate your test class with @Listeners({ParallelListener.class}) to enable parallel execution.
What is the purpose of the dependsOnMethods attribute in the @Test annotation?
It specifies that a test method depends on the successful execution of one or more other test methods before it can run.
How can you prioritize test methods in TestNG?
Use the priority attribute in the @Test annotation to specify the execution order, where lower values execute first.
What is the purpose of the @Parameters annotation?
@Parameters is used to specify parameters for a test method, and you can define these parameters in your testng.xml file.
How do you perform group testing in TestNG?
Use the groups attribute in the @Test annotation to assign a test method to one or more groups, then include or exclude groups in your testng.xml file.
How can you configure TestNG to run tests in a specific order?
You can use the preserveOrder attribute in the <suite> tag of your testng.xml file to specify that test methods should run in their declared order.
Explain the purpose of the @Listeners annotation in TestNG.
@Listeners is used to add custom listeners to your test class, which can perform actions before or after test methods.
What is Soft Assert in TestNG? Provide an example.
Soft Assert allows you to continue executing test steps even after an assertion fails. Here's an example:
java
SoftAssert softAssert = new SoftAssert();
softAssert.assertEquals(actual, expected);
// Continue with test steps
softAssert.assertAll(); // This will report all failures at the end
Explain TestNG listeners and provide an example of a custom listener.
TestNG listeners are interfaces that allow you to customize test execution. Here's an example of a custom listener:
java
public class MyListener implements ITestListener {
// Override listener methods like onTestStart, onTestSuccess, etc.
}
How can you skip a test method in TestNG?
Use the @Test(enabled = false) annotation or the @Test annotation with enabled = true or false to skip or execute a test method.
What is the purpose of the @DataProvider and @Factory annotations?
@DataProvider supplies data to test methods, while @Factory creates instances of test classes, allowing dynamic test creation.
Explain TestNG's reporting capabilities and how to generate test reports.
TestNG provides built-in HTML reports. You can also integrate it with tools like ExtentReports or TestNG's IReporter interface for custom reporting.
How can you set up TestNG in a Maven project?
Add the TestNG dependency in your pom.xml, and then configure your test classes and suites in a testng.xml file.
What is the purpose of the @BeforeSuite and @AfterSuite annotations?
@BeforeSuite runs setup code before all test methods in a suite, and @AfterSuite runs cleanup code after all test methods.
Explain how to pass parameters to a TestNG test using the testng.xml file.
Define parameters in the <parameter> tag inside <test> or <suite> tags in testng.xml, and reference them using @Parameters in your test class.
How can you run TestNG tests from the command line?
Use the java -cp command with the org.testng.TestNG class and specify the testng.xml file as an argument.
Execute test cases from class payment?//payment is class name
<suite name="API Automation Smoke Suite">
<test name="Automation Test Cases">
<classes>
<class name="<nameofthepackage>.payment"/>
</classes>
</test>
</suite>
Execute multiple classes from a package using testng xml suite?
<suite name="API Automation Smoke Suite">
<test name="Automation Test Cases">
<classes>
<class name="apiautomationeleven.test"/>
<class name="apiautomationeleven.registration"/>
<class name="apiautomationeleven.payment"/>
</classes>
</test>
</suite>
Explain testNG annotation in sequence with real time scenario?example of @After@Before in TestNG?selenium interview qus/testng
Execute all classes from a package using testng.xml suite?
<suite name="API Automation Smoke Suite">
<test name="Automation Test Cases">
<packages>
<package name="apiAutomationeleven" />
</packages>
</test>
</suite>
How to run automation suites with groups?
<suite name="API Automation Smoke Suite">
<test name="Automation Test Cases">
<groups>
<run>
<exclude name="brokenTests" />
<include name="SmokeSuite" />
</run>
</groups>
</test>
</suite>
How to use dependsOnGroups?
@Test(description="B_Users:Validate 200 status code for /users GET API",dependsOnGroups="Auth_OAUTH")
How you can specify your group dependencies in the testng.xml file. You use the <dependencies> tag to achieve this
<suite name="API Automation Smoke Suite">
<test name="Automation Test Cases">
<dependencies>
<group name="B_User" depends-on="Auth_Oauth" />
</dependencies>
</test>
</suite>
How to use @Parameters in TestNG?
@Parameters({ "first-name" })
@Test
public void testSingleString(String firstName) {
System.out.println("Invoked testString " + firstName);
assert "Cedric".equals(firstName);
}
SCENARIO BASED REAL TIME
Question: Explain how you can achieve parallel test execution in TestNG, and what are the key attributes for parallel configuration?
Answer: Parallel execution in TestNG can be achieved using the parallel attribute at the suite, test, or method level. Key attributes include methods, tests, instances, and classes.
Question: How can you implement data-driven testing in TestNG, and what annotations or attributes are involved?
Answer: Data-driven testing is achieved using the @DataProvider annotation and associating it with the dataProvider attribute in the @Test annotation.
Question: Describe how you handle test dependencies in TestNG, and what annotations are used for this purpose.
Answer: TestNG allows dependency management using the dependsOnMethods and dependsOnGroups attributes within the @Test annotation.
Question: How do you group tests in TestNG, and what mechanisms are available to control the execution of specific groups?
Answer: Tests can be grouped using the @Test(groups = "group_name") annotation. Execution control involves including or excluding specific groups in the XML suite file.
Question: Explain the role of listeners in TestNG, and how you can generate detailed test reports using listeners.
Answer: Listeners like IInvokedMethodListener and ITestListener allow you to customize test behavior and generate detailed reports. Utilize tools like Extent Reports for enhanced reporting.
Question: How can you parameterize your tests in TestNG, and what is the significance of the @Parameters annotation?
Answer: Test parameterization is achieved using the @Parameters annotation in conjunction with the parameter attribute in the @Test annotation.
Question: What is a TestNG suite, and how can you configure and run multiple test classes using XML configuration?
Answer: A TestNG suite is a collection of test classes. Configuration is done using the XML suite file where you define test classes, groups, and parameters.
Question: How can you handle expected exceptions in TestNG, and what annotations are involved?
Answer: Use the @Test(expectedExceptions = Exception.class) annotation to handle expected exceptions during test execution.
Question: Explain the concept of soft assertions in TestNG and how they differ from traditional assertions.
Answer: Soft assertions, provided by the SoftAssert class, allow the execution of subsequent test steps even if an assertion fails, providing a comprehensive test report.
Question: Discuss how you integrate TestNG with Selenium for automated testing, and what are the benefits of this integration.
Answer: TestNG and Selenium integration involves creating test scripts using TestNG annotations, allowing better test organization, parallel execution, and reporting.
