TestNG is launched by Cedric Beust. It is automation testing framework during which NG stands for “Next Generation”.

It gives an in depth report which gives details about handed, failed and skipped check case particulars.

This framework impressed from JUnit framework. This framework is healthier than JUnit framework.


  • TestNG helps parallel execution.
  • TestNG permits us to create dependent checks, prioritize checks and permits us to group the checks.
  • With the assistance of @DataProvider annotation, knowledge pushed strategy may be achieved via TestNG framework.


  • TestNG helps solely Java.


JMeter is an open supply testing software program which can be utilized to carry out load and efficiency testing for net companies, cellular and API.

This software program can conduct load and efficiency check for a lot of server varieties similar to Web, database and mail.


  • JMeter helps Record and Playback characteristic.
  • JMeter run on a number of platforms since it’s a pure Java desktop utility.
  • JMeter check outcomes may be visualized utilizing chart, desk, log file and tree. Performance of varied companies may be analysed and measured utilizing this software program.


  • JMeter doesn’t suites for desktop purposes.


Robotium was launched and developed by Renas Reda. It is an Android check automation framework which gives full help for native and hybrid purposes.

Test scripts may be written utilizing Java. It can be utilized to write down useful, system and consumer acceptance check circumstances.


  • It has easy API, so much less time is required to write down check circumstances.
  • It may be simply built-in with Maven and ANT.


  • Robotium can’t check flash parts.

Robot framework

Robot framework was launched and developed by Pekka Klarck. It is a generic automation testing framework for consumer acceptance testing and acceptance check pushed growth. It follows key phrase pushed strategy.


  • Robot framework is utility and working system impartial.
  • Robot framework check case may be written utilizing pure language itself. A check report will get generated as soon as the execution is full. Reports can be found as a HTML/XML format.


  • Robot framework doesn’t help parallel execution immediately.


Cucumber is testing framework primarily based on Behaviour Driven Development (BDD). It makes use of a easy grammar outlined by a language known as “Gherkin” to outline utility behaviour. This framework is written utilizing Ruby.

It writes its checks eventualities in Given/When/Then format. This situation file known as characteristic file which is the entry level for any cucumber checks.


  • Cucumber helps scripting languages like Java, Perl, PHP, Python and DotNet.
  • Cucumber is on the market as a plugin in eclipse software program.


  • Cucumber framework helps solely net purposes.


Espresso is a testing framework for android to write down dependable check circumstances for cellular utility consumer interfaces.

This framework is usually suites for white field automation check circumstances the place the check can immediately work together with the appliance below check implementation code. It has main three parts.

  • ViewMatchers
  • ViewActions
  • ViewAssertions


The Grinder was initially developed by Paco Gómez and Peter Zadrozny. It is a Java-based load testing framework. Default scripting language for Grinder is Jython (Java implementation of python).

It additionally helps Java and Clojure scripting languages. This framework can be utilized for distributed load testing. It has two most important parts:
