TestNG is one of the popular automation frameworks in the software development lifecycle (SDLC). The intro of this framework has brought a number of benefits for test engineers, especially in speeding up the testing practice, achieving accurate results, etc.

Along with these,Guest Posting there are even many exceptional features, which make TestNG even more effective such as support for data-driven testing, assurance for better reporting, support for parameterization, etc. However, to make software testing practice more efficient with the TestNG framework, it is essential for the teams to have complete knowledge of the TestNG framework and their features.

Automation frameworks have crucial importance in the software testing lifecycle. They help in determining how an automation project can be organized for achieving greater results. With the usage of frameworks, testing teams can achieve several benefits such as an increase in the testing speed, accuracy in the test results, reduction in the maintenance costs, etc. There are many great automation frameworks, and TestNG is one of the top automation frameworks, that has gained huge popularity because of its efficient performance and features.

 

What is TestNG?

TestNG is an automation framework that was built by considering the JUnit framework as an inspiration. In this TestNG framework, NG stands for “Next Generation”. The introduction of this framework is successfully helping several teams in overcoming the drawbacks and challenges that are caused by the Junit framework. This framework became a popular framework at a lesser time because of its benefits and a wide range of features.

Benefits with TestNG Framework:

  • The framework helps in generating logs
  • With this framework, it is possible to perform data parameterization
  • It allows the feature of annotations, which makes the testing practice is easier for test engineers
  • TestNG frameworks efficiently helps in performing parallel testing
  • With this framework, it is easier to group and prioritize test cases
  • It gives the option of generating HTML reports after execution

What are the top features of TestNG Framework?

  • Supports Data-driven testing: This framework provides the feature of data-driven testing for various test methods. Thus, it helps in executing test methods a number of times according to the provided data
  • Assures better reporting: With this TestNG framework, it is easier for test engineers in generating HTML and XML reports after its test execution. Also, with this feature, it is easier to do custom reports
  • Allows to Group: With this TestNG framework, it is easier to assign test methods into certain named groups. Also, with this feature, the user can include and exclude a certain group of tests.
  • Enables Parameterization: This feature of TestNG helps users in passing parameter values with the XML configuration files and then to the test methods. These can be further used for internal testing.
  • Allows API Extension: The TestNG framework provides the feature of API extension. With this feature, users can add custom extensions and plugins based on the requirement.
  • Provides before and after annotations option: Under this popular framework, there are a number of Before and After annotations to support a number of cleanup and setup options.
  • Supports various assertion types: The framework has an Assert class where multiple methods can support a number of assertion types such as the assertion of conditions related to true or false, adding value as null, etc.

Other features include:

  • Provides support for various execution models
  • Allows extendibility for using various automation tools and plugins
  • The framework provides the feature to embed BeanShell
  • The design of TestNG helps in providing support for various testing types like integration testing, unit testing, end-to-end testing, functional testing, etc.
  • The framework is efficient in providing the ability to generate test reports for both XML and HTML formats

 

Conclusion:

TestNG is playing a crucial role in determining how a software testing project should be organized by test engineers for achieving better results. The framework is inspired by the JUnit framework and it is capable of overcoming the drawbacks that are caused by the JUnit framework. With its wide range of features and eminent benefits, the framework has become a very popular automation framework for many enterprises. Leverage software testing services from leading next-gen testing services providers to make software testing projects more efficient.
