DevOps can be defined as the philosophy of efficient development, deployment, and operation using the highest of all possible software available as on the day. Having said that, let us take a look at all possible DevOps tools available for consumption by Organizations with no further delay. This listing of DevOps tools will be based upon implied subscriptions for usage, hence a careful study is required on the way each of these DevOps tools works towards achieving an Organization’s goals. We will try to present each of these tools, explain their features, and also provide you with the reasons why you should be choosing (if you are willing to choose it).
With the understanding that we have on DevOps as such and also with the basic understanding of what is required for your organization (that is, the requirement for your organization via DevOps), we can now take a quick look at all the possible Testing DevOps options available as on today to pick that best suits your needs. Let us not delay this any further and get going with the listing of the products.
The tool QF-Test is a cross-platform software for the GUI test automation that specializes on Java/Swing, SWT, Eclipse plug-ins and RCP applications, Java applets, Java Web Start, ULC. Alongside all these, it also specializes in cross-browser test automation of static and dynamic web-based applications (HTML and AJAX frameworks like ExtJS, GWT, GXT, RAP, Qooxdoo, Vaadin, PrimeFaces, ICEfaces and ZK). The latest versions of the software too, Version 4.0 added Windows support for the Web browser Chrome, support for JavaFX and the AJAX frameworks jQuery UI and jQueryEasyUI were added.
Following are some of the advantages of using QF-Test, let us now take a look at each and every one of them:
The next tool that we are going to discuss is SpecFlow that allows a Quality Assurance engineer to define, manage, and also automatically execute all the human-readable acceptance tests in the varied .NET projects. To have functional test cases and to have the perfect understanding of the product and to test against these functionalities is one of the cornerstones of the Business-Driven Development (BDD) paradigm.
SpecFlow that comes with a BSD license, is part of the Cucumber family that uses the Gherkin parser to support the .NET Framework and Xamarin. SpecFlow can easily be integrated into the Visual Studio IDE and at the same time, it can be used from the command line as well for the integration with a build server, for example. SpecFlow+ provides much more features like Visual Studio Test Explorer integration, dedicated Test runner with much more advanced test execution options.
Following are some of the advantages of using SpecFlow, let us now take a look at each and every one of them:

Selenium is a portable software testing framework that is directly targeted towards testing web applications. It is a popular freeware, open-source tool that caters to the very need of functional testing of web applications with immense benefits. One of the most important benefits that it provides is the record and playback feature for testing the web applications, which can be done in multiple runs on various varieties of browsers. Selenium community provides a promising roadmap with its future releases and it is expected to cater to much more diverse business segments going further. All that spoken, let us take a look at the benefits that it provides:
Cucumber is yet another software testing tool that computer programmers use for testing other software providing its support to Behavior Driven Development (BDD). It runs automated acceptance tests written in a behavior-driven development manner of testing. To be more precise, it can be introduced as a test framework that is driven by the plain English text. The test suite in itself can serve the purpose of Product documentation, Development aid, and finally as Automated Test Cases as well.
Cucumber reads the code written in plain English text using a language named ‘Gherkin’ from the feature file. It carefully finds the exact match of each of the steps from the steps definition (code file). Then the piece of code to be executed might be from different software test frameworks like Selenium, Ruby on Rails, etc. Not every BDD framework tool provides is support to other tools and hence the reason Cucumber stands tall amongst its competitors as like JBehave, JDave, and Easyb, etc. Cucumber supports different sets of software platforms like Ruby on Rails, Selenium, PicoContainer, Spring, Watir.
JUnit is a unit testing framework specifically for the Java programming language. JUnit has been important in the development of test-driven development and is one of the best-suited choices to perform the unit testing of the application code. JUnit provides a complete text-based command line, also AWT / Swing-based graphical test reporting mechanisms as well.
JUnit is the most commonly adopted choice by organizations around the world for unit testing in the Java programming language. It has become a standard pre-requisite for a Java developer to ensure that the code is written as well tested with a supporting set of unit test cases. JUnit is supported by most of the IDE’s and by far is an efficient testing process that comes with a plugin in Eclipse.
One of the most simple frameworks to write your Java automated test cases to verify your own code at the developer level itself.
Provides support for test assertions.
Comes in combination with dummy mocking tools as like Mockito.
Provides an ability to generate test reports and at the same time provides support to create and tests in the form of Test Suites.

TestNG is yet another testing framework for the Java programming language inspired by the already existing test frameworks as like the JUnit and NUnit. The design goal of TestNG is to cover a wider range of tests than is covered by the frameworks like JUnit. TestNG, the name itself suggests that this test framework is going to provide a next-generation level of testing capabilities than the traditional JUnit or NUnit test frameworks. TestNG is designed to be way better than JUnit, especially when the integration scenarios are to be tested.
TestNG test framework eliminates most of the limitations of the older framework and gives the developer the ability to write more flexible and powerful tests with help of easy annotations, grouping, sequencing & parametrizing. Most of the above features are either limited for use on JUnit or they are not completely achievable all by themselves. Having said that, let us now take a look at some of the features that are provided by the framework itself.

Gauntlt is an automated security testing framework that provides various hooks to security tools and helps them stay within the reach of its security. It is also one of the most common CI security frameworks that extend providing support for over a range of frequently used security testing tools. It facilitates from simple port scans to the more cumbersome and intrusive tests as like the SQL injections.
To be very precise, Gauntlt can be termed as an attack framework which enables us to run a variety of attacks and as a result helps us parse these outputs in a CI (Continuous Integration) friendly way - this allows our CI servers to take necessary actions based on the response (whether to proceed with the build, create an issue or to notify someone will all be dependent on this CI configuration.)
There is a wide range of native support provided by Gauntlt (at the time of this writing) are as follows:
Sahi, an automation testing tool that works pretty well for web applications and does come in two flavors - open-source and proprietary versions. It can be mentioned as an open-source record and playback web application regression testing tool that is independent of the browser, operating system which you run it on. This very specifically means that you need to write the test scripts once for a browser and then this can be run against multiple operating systems and multiple browsers with almost no setbacks.
Sahi has been introduced into the market to aid the testers to test complex web applications. One of the best features that it comes with is that it is not limited to a single browser as like Selenium IDE. Sahi is the perfect choice of regression testing for the non-programming set of testers or the manual testers.
FitNesse is a multi-faceted DevOps software tool that fits in various places of the DevOps strategy - as a Web Server, as a Wiki and also as an Automated Testing tool for software. Based on the framework provided by Ward Cunningham for integration testing, it is specifically designed to support acceptance testing than rather just depending upon unit testing. In the context above, it facilitates as THE resource for all readable description of the system functions.
FitNesse allows users of a software system to provide specific formatted inputs, based on the interpretation of which - tests are generated automatically. These tests are executed and the output is shared with the users, which provides them quicker / faster feedback to them. The application developers need to provide details (as like the classes that are quoted "fixtures" based on certain conventions).
FitNesse was earlier written in Java for Java, but then multiple versions for several other languages have been added overall to the software tool itself. Now there is a support for more than 7 languages and the list is still growing (C++, Python, Ruby, Delphi, C# and the like). One of the best points is that the FitNesse documentation can never go out of date and hence, your tests will be passing. Since the documentation itself is your set of tests, and hence it is impossible that it lies.

Appium is yet another Opensource test automation framework that comes handy for usage with native, hybrid, and mobile web applications. Appium actually translates Selenium based commands to iOS or Android-based commands, which means the learning curve in gaining knowledge is directly dependent on the knowledge that you have on Selenium.
The communication happens via JSON over HTTP protocol, hence this enables the server and also the devices, your test scripts can all be run on totally different systems/machines. The same APIs be put to use, to write automation tests against iOS or Android platforms. This also ensures that the code can be re-used efficiently between the test suites. Even though this feature is provided by the Appium test framework, the final test scripts will still be different as the UI elements are all different for both iOS and Android.
Pytest is a mature full-featured testing tool for Python programming language, and not just that but also helps you write better Python code. Pytest can be assumed to be the run-anything, no-boilerplate and no-required-APIs test framework for Python, which makes testing real fun. It is more advantageous to use as a test framework because of its simplicity, automatic test discovery, and modular fixtures and also because of its intelligent error output.
Gatling, an open-source load testing framework that is based on technologies like Scala, Akka and Netty are basically designed to perform load tests and analyze, measure the performance of the variety of services. The major focus of this application is to perform load tests on web applications. In the simplest of terms, Gatling is framed in such a way that your performance tests are treated as your Production code. Hence the maintenance and the automation are damn easier. Gatling provides excellent support, out of the box for the HTTP protocol – hence making it an ideal choice for load testing any HTTP server. Having said that, Gatling also ships JMS support. Gatling’s architecture is asynchronous as the underlying protocol is HTTP and can be implemented in a non-blocking way.
