Defining Test Automation
Different types of frameworks
The process of building and implementing the framework
Conclusion

Developing a test automation frameworks is on the minds of many software testers these days. Even executive-level clients in software development domain have fostered extensive understanding of how implementing an automation framework benefits their business & many in this space have started uttering the term ‘framework’ quite often, knowing how it can become key to the success of software automation project. But still, to many, the question remains – what exactly is a test automation framework and automation script? How does it work and what advantages can the framework bring to the testing process?

Defining Test Automation

In any industry, automation is generally interpreted as automatic handling of processes through intelligent algorithms that involve little or no human intervention. In the software industry, testing automation means performing various tests on software applications using automation tools that are either licensed versions or open-source. In technical terms, the test automation framework is a customized set of interactive components that facilitate the execution of scripted tests and the comprehensive reporting of test results.

To successfully build an automation framework, it is imperative to consider the recommendations by software QA experts who help control and monitor the entire testing process and enhance the precision of the results. A carefully mended automation framework allows testers to perform the automated tests in a practical, simplified fashion.

Different types of frameworks

Depending on how you want to approach the creation of a framework and target automation requirements, there are various possible variables you can think of such as:

Tool-centered frameworks

Both commercial and open-source automation tools have their own system infrastructure that helps with report generation, test suits, distributed test execution in its testing environment. One example is the Selenium automation framework which has the main component WebDriver that functions as a plugin for the web-based browser to control and operate the DOM model of the application within the web browser. The Selenium test automation framework also additionally has useful coding libraries and a record-playback tool.

Another significant tool-specific framework example is Serenity that is built around Selenium Web driver and is an accelerator. In this, to possibly speed up the test automation implementation process, specific components are put together within a common substance by the community.

When it comes to tool-specific frameworks like TestComplete, Ranorex HP QTP and more, it is difficult to make the firm decision since they all are prebuilt with a deployed infrastructure with actions emulators, reporting and scripting IDE.

Project-oriented frameworks

Frameworks of this class are customized to enable implementation of automation for specific application projects. Project-specific frameworks support certain target app test automation requirements and are driven by components built from open-source libraries. It creates a test-friendly environment around SUT to run some of the essential functions. These include the deployment of the developed application, running the app, test cases execution, direct test results reporting, and wrapper control for ease of coding. The frameworks focused on specific projects should also have a component to support the test run across various cloud environments on different OS and browsers.

Keyword driven frameworks

Keyword-driven frameworks are those designed to appeal to developers and testers with less coding experience. They might be tool-specific or project-focused frameworks and enable the underskilled staff to write and comprehend automation script. The keywords set (such as Login, NavigateToPage, Click, TypeText) for coding are installed as a keyword repository within a codebase. The spreadsheet where testers write scripts based on provided keyword references are passed onto the keyword interpreter, and the test is executed.

Major components of ideal test automation frameworks

If you desire to implement a highly functional and superior test automation framework, be it open-source or commercial, you must think of including certain ingredients that form its core. It is not necessary that you include all the components mentioned below in every framework. While some frameworks might have all of them, some will have only a couple.

There is always space, however, to include those not listed here. The major components of ideal test automation frameworks based on various tests are:

Testing libraries

a) Unit testing

Unit testing libraries can be used to shape an essential part of any test automation framework. You need it for:

  • Defining test methods in use via specific formal annotations like @Test or [Test]
  • Performing assertions that affect the end results of automated tests
  • Running straightforward and simplified tests

Whether you run the tests from the command line, IDE, a dedicated tool or CI (continuous integration) system – to make sure that the unit tests run straightforward manner, the unit testing libraries offer test runner.

Usually, unit testing libraries support almost every programming language. A few great examples of unit testing libraries are:

  • JUnit and TestNG for Java
  • NUnit and MSTest for .NET
  • unittest (formerly PyUnit) for Python.

b) Integration and end-to-end testing

While performing integration and end-to-end testing automation, practicing the features provided by existing test libraries is healthy and often recommended. API-level tests that are driven by the UI of an application require components that make interactions with applications under test quite easier as it eliminates the unnecessary burden of coding. Thus, you will not focus on coding efforts for:

  • Connecting to the application
  • Sending requests
  • Receiving resultant responses

Several important testing libraries of this ilk are:

  • Selenium (Available for major languages)
  • Protractor (Specific to JavaScript)
  • Karate DSL (Java-specific API-level integration tests)

c) Behavior-driven development (BDD)

Libraries dedicated to BDD target behavioral specifics, creating executable specifications in the form of executable code. Here you can convert different features and scenarios of expected behavior into code though they don’t work like test tools directly interacting with the application under test. They function as a support to BDD process to create living documentation that aligns with scope and intent of automated tests. A set of typical examples of BDD libraries would be:

  • Cucumber (supports major languages)
  • Jasmine (JavaScript)
  • SpecFlow (for .NET)

Test data management

The biggest struggle experienced during the software testing automation and tests creation process is harnessing the system of test data management. As the number of automation tests intensify, there’s always the problem of ensuring that certain test data required to perform a specific test is available or created when the tests are carried out. The challenge is that there is no surefire solution to this, which demands to adopt a solid approach for test data management to make automation efforts a success.

This is why, the automation framework you use, should be equipped enough to offer an essential remedy to enter or create and scavenge through the test data to be executed. One way to resolve this is having a proper simulation tool to make data more simplified, lucid and digestible.

Mocks, Stubs, and Virtual Assets

While exploring and working on many ideas of automated tests, you are likely to come across one the situations where:

  1. You want to isolate modules from connected components that are generally experienced in unit testing
  2. You need to deal with cumbersome and critical dependencies as commonly found in integration or end-to-end tests for modern applications

In such cases, you might feel it is essential to create mocks, stubs and virtual assets that mirror the behavioral pattern of connected components. You might find handling mocks and stubs being a big-scope, giant task; however, you will realize how crucial it is to opt for useful virtualization tools during the development of automated testing frameworks.

Common Mechanisms for Implementation Patterns

Aside from the automation framework components discussed above, there are a couple of useful mechanisms that help with the creation, use, and maintenance of automated tests such as:

  • Wrapper methods: When you use Selenium WebDriver component, creating custom wrappers makes error handling more comfortable. As custom wrappers for Selenium API calls are created, you can better handle timeouts, exception handling and fault reporting. It can then be reused by those who create automated tests so that they can steer clear from the concerns of complicated process and focus on making valuable tests.
  • Abstraction methods: The abstraction mechanism stands for increasing readability and obscuring redundant implementation details. For instance, using Page Objects while creating Selenium WebDriver tests aims to expose user input actions on a web page including entering credential or clicking somewhere on a page. The goal is to accomplish high-level test methods by transcending or bypassing the need to explore specific elements of the page. This method applies to many similar applications and automation tests.

Test results reporting

When it comes to selecting a library or mechanism for reporting of the test results into the automation framework, you should focus primarily on the target audience that will be reading or reviewing the generated reports. In this area, we can present several considerations:

  • Unit testing frameworks such as Junit and TestNG generate reports that primarily target receptive systems such as CI (continuous integration) servers that ultimately interpret it and present it in XML format consumable by other software.
  • As we seek tools that have reporting capabilities in a language most understood by humans, you may need to consider using commercial tools that are compatible with Unit testing frameworks such as UFT Pro for Junit, NUnit and TestNG.
  • Another option is making use of third-party libraries such as ExtentReports that create test result reports in formats well interpreted by humans, including visual explanations through pie charts, graphics or images.

CI platform

For a faster and consistent approach towards application testing, Continuous Integration platform can help build software and run various tests for the new build on a periodical basis. This approach gives developers and stakeholders an opportunity to draw regular feedback and faster responses regarding app quality as and when new features are developed and deployed and existing ones are updated. A few prominent examples of current CI platform could be TeamCity, CircleCI, Jenkins, Atlassian Bamboo, etc.

Source code management

Like manual testing, automation testing also involves writing and storing source code version. Every development company has a curated source and version control system to save and protect source code. Automated tests require a sound source code management system that comes handy when working on production code. Some typical examples of source code management, as any developer would give are Git, Mercurial, Subversion and TFS.

Create dependency managers

The primary intent of dependency managers is to assist in the process of gathering and managing existing dependencies and libraries used in the functioning of automation software solutions. Certain tools like Maven and Gradle simultaneously act as dependency managers and help in building tools. Build tools are meant to help you develop the automation software from source code and supporting libraries and run tests. Other dependency tools include Ant, NPM and NuGet.

The process of building and implementing the framework

There are a few ways to plan an approach for implementing an automation test solution.

  • Explore the practical suitability of automation from a customer’s Check if it looks good from all angles and test it on technology under use. It may seem a little unfeasible if, when compared, automation development endeavors outweigh expected advantages by a considerable margin.
  • It is crucial to keep an eye on the technology of the system under test to settle for the most appropriate test automation tool that perfectly emulates user actions.
  • It is advisable to go for a stage-based implementation approach where each stage has the priority of delivering an automated test script while adding framework features to achieve the expected execution of scripts.
  • Before initiating software test automation, to ensure the decision of automation is executed correctly, it is essential to first calculate and estimate the post-implementation ROI, concept proof, time to run the manual regression or smoke test and the number of run cycles per release.

The inevitable need for test automation frameworks

Describing and illustrating how software test automation framework and scripts complement your testing process does not always mean it will work successfully work for everyone who aims for automation. However, there is no denial in saying that test automation frameworks, if planned and executed diligently do bring the following perks for a software development and testing company:

  • Minimum time – maximum gains: Any viable test automation framework and automation script is built to minimize the time taken to write and run tests, which gives maximum output in a short With an excellent automation framework in place, you feel free from the usual concerns such as synchronization, error management, local configuration, report generation, and interpretation and many other challenges.
  • Reusable and readable automation code: As you use the code mentioned in existing libraries of components, you can rest assured that it remains readable and reusable for times to come and that all related tasks such as reporting, synchronization, and troubleshooting will become more accessible to achieve.
  • Resource optimization: Some companies do not benefit as much from automation implementation as they thought before starting the process. The efficiency you gain from creating automated tests depends on the flexibility of its adoption. If the automation system is flexible and compatible with different teams working on various components, it can provide enormous benefits when it comes to resource optimization and knowledge sharing.

Conclusion

In today’s fast-paced, brutal software development ecosystem, automated tests and scripts play an integral part in maintaining the speed, efficiency, and lucidity of the software testing cycle. With AI being inculcated in software testing, organizations that thinks of adopting a test automation framework must delve deeper in creating the ultimate framework design before they ever dive into this field. A well-nurtured strategy of framework design and components to be used will prepare the fundamental backbone of the final test automation frameworks.

The best way to shape the mature, sophisticated and resilient architecture of test automation framework is to start small, test and review frequently, and gradually go higher to build an expansive version. You may also find it convenient to prepare the enormous set of automated tests from early on to see the working framework in place sooner and avoid a conflicting or compromised situation later during the test automation phase.

The guidelines explained above is intended to help software testers, and companies immensely benefit from their successful execution of test automation projects.
