The different types of Test Automation Frameworks

 

 

 Testing remains a critical component of any software development process. This is because it ensures the identification and removal of all bugs in the code, the delivery of superior customer experiences, greater adoption of the software in the market, and increased profitability for the enterprise. The process of testing has undergone considerable improvements in the last few years with the automated testing approach being adopted for its slew of benefits. As opposed to manual testing, a test automation strategy automates the testing of software applications to speed up the development process and make the software application glitch-free, efficient, and reliable. However, to implement test automation, enterprises need to utilize test automation frameworks to drive faster releases of quality products.

What is a test automation framework?

To begin with, a framework is a structure of protocols, rules, and guidelines, which can help an enterprise to derive the optimum benefits for a concept or idea. In the same vein, the structure called a test automation framework helps to execute and generate test results. The key components of such a framework are test tools, equipment, test scripts, automation engineers, and procedures. The framework determines if the test results are in alignment with the expected results. Being independent of the software application, a framework can be expanded according to the testing needs of any application and helps to improve test coverage and the quality of products. 

What are the benefits of a test automation framework?

Using such a framework in executing QA automation testing garners the following benefits for the team.

• ·        Better test efficiency
• ·         Better speed and reliability
• ·         Optimization of resources
• ·         Remote testing
• ·         Reduced manual intervention
• ·         Parallel testing
• ·         Bug fixing at an early stage
• ·         Enhanced test coverage
• ·         Code reusability
• ·         Less maintenance cost
• ·         Increased ROI

What are the different types of automated frameworks?

Automated testing services use different types of frameworks to derive the best test outcomes. However, it is important to select the right type for testing the software application under consideration.

# Linear automation framework: The simplest of all frameworks is also known as a record-and-playback framework. Here, the testers need not write the custom test codes and the test process is mentioned in sequential order. It is mainly used for introductory level testing and converts medium or small-sized manual scripts into their corresponding automation scripts. However, on the flip side, the scripts cannot be reused as the data is hardwired into them.

Advantages

·         The tester does not need to be an expert in test automation as there is no need to write any custom code.

·         The testing process takes less time

·         The test workflow is simple to understand as the scripts are written in a sequential order

·         Arguably the best framework to start with automated software testing thanks to its record-and-playback features.

# Module-based framework: Based on Object-Oriented Programming or OOPs, the framework uses abstraction as its concept. According to this, the application under test is divided into various modules wherein each module comprises individual test scripts. Since the modules are separated using the abstraction layer, any changes made to the individual modules do not impact others. The flip side of this framework is that it requires the knowledge of programming language to set up.

Advantages

·         Since the framework comprises of several modules or sections, the cost and ease of maintenance are less.

·         Easy to create new driver scripts.

·         Can be scaled easily and should any defect be found the rest of the overarching module does not need to be touched.

# Library architecture testing framework: Here, tasks with similarities to the test script are identified followed by the testers executing the function-based grouping of similar tasks. Thereafter, the library stores the sorted functions that can be called by the test scripts upon requirement. The framework needs more time and technical expertise to be set up.

Advantages

·         Better reusability of codes compared to the ‘record and playback’ model

·         High level of modularization leading to easy maintenance and scalability of test scripts

# Data-driven framework: In this type of automated testing approach, the inputs and expected results are stored in separate files. Also, a single driver test can perform all test cases with various data sets. The framework entails the segregation of test data and test script logic facilitating code reusability.

Advantages

·         Test executable using multiple data sets

·         Any changes made to the test script do not impact the test data

·         Any number of scenarios can be tested by changing the data sets

# Keyword-driven testing framework: This application-independent framework separates test data and script logic followed by storing the data and keywords externally in a different location. It is more suitable for automated web testing and needs the selection of keywords and data tables.

Advantages

·         Does not require deep knowledge of scripting

·         Reusability of code as a keyword can be used across test scripts

·         Test scripts can be developed independently of the software application being tested

Conclusion

To facilitate faster release of quality software applications under the Agile and DevOps methodologies, choosing the right test automation framework is critical. The criteria to choose any test framework may include the reusability of test scripts, minimum human intervention, and quick identification of glitches, among others.

How Test Automation helps Agile to be successful?

To meet the stringent quality requirements of complex applications, the Software Development Life Cycle has changed. If earlier, the waterfall was the preferred model with testing done at the end of development, it has given way to Agile today. This is because the waterfall model suffered from a lot of inconsistencies and did not deliver the right results. Also, it increased the cost of software development and testing for businesses. The need for Agile was felt due to the growing complexity of software applications. As the new software applications come with endpoints that interface with third-party databases, servers, or sites, the quantum of vulnerabilities has increased. If not plugged in time, once these applications are out in the market, they can be exploited by hackers leading to severe consequences for the users.

With Agile, it has become easy to detect glitches and vulnerabilities early on in the software development pipeline. Also, to keep pace with shorter release cycles, enterprises are adopting Agile test automation. This is to ensure the software conforms to the exacting standards of quality. Further, with plenty of features being added to the software in every sprint, developers need to ensure they do not affect the existing functionalities. Also, as the sprint is of a shorter duration, it is not possible to test and execute the entire software suite every time a feature is added. This is where Agile test automation can help by running the codes iteratively.

Why Agile development needs automation?

The Agile model entails the development, testing, and delivery of glitch-free software products within fast turnarounds. Since the process can involve repeated changes, a robust test automation strategy should be put in place. For Agile testers, there are several challenges to be addressed with Agile test automation.

Challenges for Agile testing

Even though adopting an Agile testing framework delivers a string of positive outcomes, it can entail some challenges too. These include

Inadequate test coverage: During the later sprints when a number of features are added to the build, the testers get lesser time to test them and analyze their impact. In such conditions, a few user stories are left untested with the hope that they would not affect the release. However, by automating the Agile application testing process, the build can be put through a regression testing exercise to achieve assured quality.

Frequent build leading to cracked code: In Agile, there can be instances of frequent code changes due to the addition of features to the build. These changes can lead to cracked codes, especially during the integration phase. Further, to implement a continuous integration and deployment pipeline (CI/CD), the Agile testing experts ought to implement test automation.

Performance issues: It can often be the case when improving the functionality of an app can end up complicating it further. Since every change can lead to an increase in the volume of codes, the performance of the app can take a hit. However, conducting Agile performance testing using automation tools can identify the performance issues.

Compatibility issues: Any software of the day should be checked for its compatibility across devices, operating platforms, browsers, and networks. Ideally, testers should ensure the seamless run of software across devices. An automated test run can check for glitches or vulnerabilities in the endpoints and APIs, and make sure the compatibility issues are sorted.

API testing: A web or mobile app involves the implementation of complex APIs, the quality of which is often overlooked. Automation testing tools such as LambdaTest can help Agile testers to overcome such issues.

Things to automate in Agile

When it comes to introducing automation in testing, areas like regression testing or smoke testing take the cake. However, these are just the top layers of the build, which can be insufficient as far as ensuring the quality of the software is concerned. The other areas where test automation can be implemented are

·         Builds and deployments

·         Unit tests

·         Non-functional testing

·         API testing

·         GUI testing

·         Repetitive tasks like data comparisons

Benefits of test automation

Agile development can be benefited from automated testing in a number of ways related to performance, portability, versioning, reliability, usability, and speed, among others. The benefits include

·         Enhanced quality

·         Quick turnaround

·         Repeat execution

·         Seamless performance

·         Better collaboration

Conclusion

The Agile testing approach can lead enterprises to create a better software development pipeline. Its success is underpinned on the level of implementing test automation. The automation-led Agile methodology combined with DevOps has the potential to improve the quality of software and deliver great user experiences.

The use of Automated Testing in a CI/CD Pipeline?

The rigors of the market and changing user preferences have focused on the need for developing quality applications. Since quality can be a relative term changing across processes and based on numerous in-situ parameters, methodologies like Continuous Improvement or Continuous Delivery (CI/CD) become important. In other words, any software needs to be upgraded continually based on user feedback and market trends. Enterprises are increasingly embracing Agile and DevOps to build new products and services within short turnarounds. However, such speedy development cycles can lead to the release of bug-infested software. This is due to the fact that both developers and testers get less time to validate all the quality parameters. Moreover, it is often observed that developers and testers focus on activities/elements like code repository management, integration, and CI servers. Surprisingly, automated testing services are often not on the list of developers notwithstanding the demand for quick release cycles and increasing complexity of software.

What is automated testing?

It involves the testing of software codes using scripts, frameworks, and tools. Here, preconfigured tests are executed to validate the features and functionalities of software against a given set of parameters. At the end of testing, the automated testing framework prepares a detailed report of the test including the glitches found.

Let us understand what benefits automated application testing brings to the table vis-a-vis the CI/CD pipeline.

Why the CI/CD pipeline needs automated testing services?

A software needs periodic upgrades to remain aligned with the market needs and technology changes. A robust continuous integration and testing mechanism can ensure quick feedback on the changes. It helps to identify glitches quickly before the product hits the market. To enable the same, automated testing solutions should be harnessed. These can provide stakeholders with accurate information on the inherent risks thereby helping them to take informed decisions. By implementing a robust test automation strategy wherein various tests are run continually, the resultant product turns out to be glitch-free and delivering superior user experience.

Benefits of using an automated testing strategy in CI/CD pipeline

With the complexity of software applications increasing and delivery schedules reducing, it has become imperative to validate their functionalities across devices, operating platforms, browsers, and networks. This is where an automated testing strategy can help in the following ways -

• Quicker tests: Since CI/CD pipeline requires speed and a minimum turnaround time, automation testing can validate various aspects of the software quickly than say, manual testing. Also, automated tests can be run for any number of times and not let glitches go undetected.
• Faster regression tests: The CI/CD process involves receiving speedy feedback from the users. The impact of changes made in the software can be validated better by using automated testing. Also, such testing can run in parallel, thereby shortening the execution time.
• Consistency: No software should have anomalies, especially during the execution of continuous integration. Automated testing can identify the glitches or anomalies present in the software and ensure a consistent performance. Also, it ensures expectations are met until the product is finally released. 
• Efficient release of software updates: Frequent software updates can face challenges in removing bugs in a continuous delivery pipeline. Thus, the risk of bug infested build can increase thereby impacting the end-user experience. Automated testing can take care of such occurrences and streamline the delivery process.
• Agility: In a continuous integration and delivery pipeline, the technology, frameworks, and configurations should be amenable to changes based on the business requirements. In the absence of an automated testing framework, it would be virtually impossible to implement and validate such builds in the expected time frame. Also, it would amount to being inefficient if the QA team must wait to rewrite or reconfigure the test suites. Since test automation can reconfigure the test suites automatically, crucial build time can be saved.
• Better product visibility: Tests such as interface or unit testing can deliver greater visibility about the product at any given point in time. Test automation can provide instant feedback for developers in the CI/CD pipeline so that the latter can administer a quick-fix to the build later.

Conclusion

Software developers and testers can start small when it comes to implementing the CI/CD pipeline. As you gain experience in writing test suites and automation, the challenges that come with the job can be used as a learning phase. The benefits will soon become apparent as they go about following the best technical approach and using the right framework. In a fast-growing digital landscape, automated testing services shall be your best bet in ensuring faster release of glitch-free products.
