TestNG Introduction

TestNG is a testing framework designed to simplify a broad range of testing needs, from unit testing to integration testing, which is inspired by Junit and Nunit, but TestNG has more number of annotations than other frameworks.

TestNG is designed to cover all categories of tests:  unit, functional, end-to-end, integration, etc...

It is a Three Step Process

• Write the business logic of your test and insert TestNG annotations in your code.
• Add the information about your test (e.g. the class name, the groups you wish to run, etc...) in  a atestng.xml  file or in build.xml.
• Run TestNG

New Functionalities in TestNG

• Run your tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc...).

·         Annotations.

• Test that your code is multithread safe.
• Flexible test configuration.
• Support for data-driven testing (with @DataProvider).
• Support for parameters.
• Powerful execution model (no more TestSuite).
• Supported by a variety of tools and plug-ins (Eclipse, IDEA, Maven, etc...).
• Embeds BeanShell for further flexibility.
• Default JDK functions for runtime and logging (no dependencies).
• Dependent methods for application server testing.
