In today’s world of the digital industry, increasing the speed of entry into the market plays a key role in the success and competitiveness of companies and corporations.

As a result, many IT specialists, namely the developers, try to completely decrease the time for testing the product in development. Since it’s not a secret that regression testing takes too much time and sometimes the date of a final release is shifted for an indefinite period.

Test Automation

The sooner a process of testing starts, the sooner a product will be delivered to a client who will, in his turn, implement it in the environment of potentially interested users. That’s why in the process of testing, it’s better to use modern capabilities of automation of this product (no matter what you are testing – a web product or a mobile utility).

And such frameworks as Junit and TestNG help specialists of QA department in this way.

Description of TestNG

TestNG is quite a popular automation framework, completely built on Java programming language and which took some things from JUnit. It is simple to use, has numerous available functions and is also efficient in test suite design in order to automate different web products.

Functions of TestNG:

• Complete annotation of performed operations;
• Has XML for complete configuration of designed tests;
• Works with data-driven tests;
• Using the methods of checking server utilities;
• Complete technical support of Hudson, Ant, IDEA and Eclipse;
• The multi-flow function of testing the program code;
• Intuitive interface.

And with the help of TestNG tool, you can easily cover any type of tests: functional, end-to-end, integration and unit tests. For this purpose, we advise using JDK (a special Java Development Tool 5).

TestNG allows us to reach a complete parameterization of information.

In the process of working with this framework, the process of designing test suites consists of the following parts :

• Development of future logic of test;
• The process of implementing the TestNG annotations into a program code;
• Start of TestNG work.

You can also add additional parameters to existed annotation. Since all annotations are standard, a compilator will quickly find an error and will show a tester where to search for a bug.

It means that the process of testing of /software products with the help of special TestNG tool is a correct way to completely decrease the time for testing of a product before a final release.

Description of JUnit

There are some developers who always criticize JUnit module testing library, apparently pointing out that such web tools are overrated since we can create a similar product by ourselves just in a few minutes.

It’s true to some extent but even such statements don’t decrease their brilliance and easiness in usage.

The technological efficiency of Junit tools depends completely on the clients. Only a user, in our case – a tester, decides what tools and library collections to use in each case.

Usually, JUnit is used for the following aims:

• Processes of automating the functional testing and also its separate parts and groups;
• Organization and sorting of tests according to their functionality;
• Organization of typical data and similar files and materials.

Right with the help of these simple but really useful operations/actions, testers can perform complex testing of software in development, check/test mobile utilities and also permanently improve their skills and make the process of testing quicker and more productive/efficient.

How to Create a Simple Test in JUnit

Let’s analyze how to create the simplest test in JUnit. All operations should be performed in a random order of Test Case.

For such a purpose, we can use a classical master for test creation or a specialized utility of Test suite:

• Firstly open a wizard (files – JUnit test suite);
• Choose the “JUnit test creation”;

• Then you should add a particular method of testing which will show a system error. For this, you can use a template which is called “test”.

In order to run the tests, you should use a special key which is placed in the shortcut menu. The test you have created should be run as JUnit Test.

All available results can be viewed in developer tools of JUnit.

Additionally, you can also view current data on test execution.

Besides creating and running the tests, you can also do the following:

• Run all available tests which are in one package one after another;
• Perform testing, using one established method of testing;
• Repeat performed test suite.

To conclude, we’d like to admit that application testing services always rely on the big choice of functional and technological capabilities which are always operated by the QA department together with the team of developers.

JUnit and TestNG frameworks are useful web tools which allow you to completely differentiate the process of automation both in the process of working with web product and in the process of developing a particular mobile application or utility.

You can compare them according to numerous criteria or search for advantages in the race with each other, but still, the more functional advantages QA specialist uses, the better is for the whole development department!
