TestNG Framework: Complete Beginner to Advanced (Hands-On)

Install and configure TestNG with Maven in Eclipse by adding the dependencies, selecting a suitable version, and installing the plugin via the Eclipse Marketplace.

Learn to set up a TestNG Java project in Eclipse, create and run simple test methods, view reports, and understand annotations and configuration for stable test execution.

Unlock the basics of TestNG annotations as metadata backed by implementations, and master the execution order—before suite, before test, before class, before method, and their corresponding after counterparts.

Compare tests with and without TestNG, using a simple main method versus a TestNG annotated test to verify a web page title and review test reports.

Learn to run multiple test classes in TestNG by configuring parallel execution and class-level selection. Explore labeling and organizing classes to execute the desired tests in a single run.

Discover how to perform multi-class executions in TestNG, observe all test methods run across selected classes, and extend coverage by adding more classes to the run.

Log test steps to the report using Reporter.log and verify that console messages appear in the report, including steps like launching the browser, getting the title, and verification results.

Explore how to use TestNG's invocationCount to run a single test method multiple times, illustrated with a login scenario of multiple incorrect attempts, unlock, and subsequent login.

Learn how TestNG orders test cases by default alphabetical method name, and how to control execution with priority, using examples that set priority values like 1, 2, and 3.

Explore prioritising test cases in TestNG with real-time examples, assigning priority values (including negative and default zero), and observing execution order from lowest to highest, with alphabetical tie-breaks.

Discover how to skip TestNG test cases in real time using enable flags and skip exceptions, and control reporting with an escape action plan.

Explore how to enforce test execution order in TestNG using dependsOnMethods, creating real-time dependencies such as open browser, sign in, and log out, and pass data between tests.

Learn how to group test cases in TestNG, create groups like smoke, regression, and sanity, and run targeted sets to speed up real-time testing and validation.

Group test methods in TestNG, run specific groups with include and exclude rules, and manage group setup to execute sanity tests and targeted test suites.

See real-time grouping of test cases in TestNg, create separate smoke and sanity files, configure group runs, and exclude tests to target essential groups.

Learn how assertions verify test conditions and decide pass or fail, using hard and soft assertions and exception handling to guide test outcomes.

Compare soft assertion and hard assertion in TestNG with practical examples, showing how soft assertions collect failures and use assertAll to mark the test as failed only at the end.

Discover how TestNG enables parallel testing and parallel execution using multi-threading to run multiple Selenium tests simultaneously, reducing overall execution time.

Explore real-time parallel execution of two Selenium tests across Safari and Chrome, using multi-threading and thread count to run tests simultaneously and resolve browser conflicts.

Explore data driven testing and parameterization by testing a login form with multiple input datasets at runtime, validating valid and invalid credentials and error messages.

Learn how to implement data-driven testing in TestNG by using parameterization and data providers to run the same test with multiple inputs, reducing hard-coded data and code complexity.

Explore parameterized testing in testng, using data providers to run login tests with multiple username and password sets, avoiding hard-coded data and enabling data-driven test design.

Explore how TestNG handles parameter levels, comparing test level data with suite-wide data, and learn to feed multiple datasets using data providers across tests.

Learn how to use data provider for data driven testing by feeding multiple data sets into a test method using a two-dimensional object array, with username and password examples.

Learn to invoke a data provider from a different class using an Excel-backed data provider, enabling login and sign-up tests across classes.

Learn to implement a real-time data provider in selenium tests by driving a Facebook login with multiple datasets, validating username display for successful logins and handling invalid credentials.

Learn how TestNG listeners modify default behavior by listening to test execution, logging starts, skips, successes, and failures, with practical examples and common listeners like ITestListener.

Explore how to implement the TestNG ITestListener to log test start, success, failure, and skip events, and apply it to capture and report test execution in a project.

Use a generic test listener in TestNG via ITestListener to apply across multiple test classes, capturing test names and taking screenshots on failure.

Explore how to implement and use the ITestResult listener in TestNG to capture test pass or fail statuses, access test names, and apply results across tests using after methods.

Implement the IInvokedMethodListener in TestNG to monitor method invocations, override before and after invocation methods, and capture test names and statuses for logging and reports.

Learn how to implement the TestNG ISuiteListener to track suite-level information, initialize resources before a suite starts, and close connections after it finishes.

Consolidate the three TestNG listeners into a single class and implement them to enable test-level and suite-level logging.

Identify why test cases fail—network issues, script issues, or application bugs—analyze failures with developers, and re-run only the failed test cases using filters to isolate issues.

Learn how to run selective test cases and suites in TestNg using filters, view detailed failure reports, and isolate failing tests via the test output and index reports.

demonstrates a real-time approach to running failed test cases in the TestNG framework, showing automatic re-execution, minimal intervention, and selective suite execution to validate results.

Demonstrate a real-time example of running failed test cases in TestNG, showing how multiple classes and test methods fail or pass, and how to interpret suite output.
