Unit Testing with JUnit and TestNG Corporate Training
Instructor-led software testing training on unit testing with JUnit and TestNG
This instructor-led program helps your teams write reliable unit tests with JUnit 5 and TestNG. Through guided hands-on labs, participants build real test suites: assertions, mocking, data-driven tests, and CI-integrated coverage that catches defects early.

Program Overview: What is Unit Testing with JUnit and TestNG?
Unit Testing with JUnit & TestNG is Edstellar's instructor-led technical program for Java developers and QA engineers building reliable test coverage. Participants master unit testing foundations, JUnit 5, the TestNG framework, mocking and test doubles, and CI pipeline integration. The focus is craft: tests that catch real bugs and stay green for the right reasons.
Training is hands-on across 24 hours and six modules, all in code. Participants write JUnit 5 tests, configure TestNG suites, mock tricky dependencies, and wire coverage into CI pipelines, with instructor coaching at every step. Every test is reviewed with direct feedback, so developers learn the difference between a test that passes and a test that protects. The program closes with a five-hour capstone: a full enterprise test suite build on a realistic Java codebase.
Teams without unit testing discipline pay in production: regressions nobody catches, refactors everyone fears, and coverage numbers that measure files, not safety. Writing tests that actually protect requires judgment about what to test and what to mock. This program teaches your developers that judgment, with every pattern practiced in code.
The capstone hands each team a realistic Java codebase with thin, brittle tests and asks for an enterprise-grade suite: JUnit 5 and TestNG where each fits, mocks for the painful dependencies, CI wired with coverage gates. Instructors review it like a senior engineer would, hunting for tests that pass without proving anything. The team walks away with a test suite they can defend in review and a template for testing every service they build next.
The program is built for Java developers, QA engineers, and SDETs who own code quality. Concepts are taught live with production-style code examples, and every module includes guided hands-on labs where participants build real test suites: writing assertions, mocking dependencies, and wiring tests into CI pipelines. The capstone lab puts it all together with instructor review.

Unit Testing with JUnit and TestNG Course Topics and Program Outline
A 24-hour instructor-led program with guided hands-on labs across 6 modules, ending in a capstone test-suite build.
Built by Edstellar with test automation engineers
Built by test automation engineers who ship Java test suites in production CI pipelines, shaped around your stack and use cases.
We review your teams' Java stack, testing maturity, and CI setup before the first session.
JUnit 5 and TestNG concepts are taught live with production-style code examples.
Guided hands-on labs build real test suites: mocking, data providers, and CI integration.
A capstone lab produces a complete, CI-ready enterprise test suite for your stack.
From testing foundations to a capstone test suite, every technique is built in guided hands-on labs.
