Test Automation Framework: How to Choose the Right One

March 17, 2021

Test automation framework

Innovation sits at the heart of software automation.

Automation and its various applications have revolutionized the software industry by reducing the burden of the manual testing effort and making systems more efficient. Test automation software, in particular, has sped up the deployment of new software products in the market.

Test automation software is backed with test automation frameworks for a streamlined execution. Automation frameworks can be best described as a tried and true recipe for the software testing process, which can be reused as many times as wanted on a particular set of applications or products.

What is a test automation framework?

A test automation framework is an amalgamated platform of tools, compilers, and programs that aid automated test scripts.

Take for instance, a mobile phone. It comes with a user manual that tells us to keep a check on the temperature around the device, how to set up a security code, or how to use your fingerprint scanner. You can say these are guidelines you need to follow if you want to use your phone in the best way possible.

A framework, similarly,  can be defined as a set of rules that need to be followed by an application to produce optimized results. A test automation framework does that for automated test software. It provides a set of internal libraries and reusable code snippets that help in running automated test scripts. It also helps in setting up secure methods for automated tests to run and provides a uniform test code syntax for the entire project or application.

Types of test automation frameworks

Creating test automation frameworks involves building a detailed set of instructions for automating test suites for a number of applications or code snippets. The exact requirement of this set of instructions differs along with the type of programs that need to be tested. 

Linear scripting framework

Linear scripting frameworks, also known as record and playback frameworks, create test scripts for individual test cases or small snippets of code. This is useful in testing smaller applications and can be employed to create test scripts in very little time. They are generally used for a sequential manner of scripting test scripts and running them on simple applications. 

Advantage: It is easily compatible with existing test automation tools since most of them already support the record and playback feature.

Disadvantage: Scripts developed using this network aren’t reusable and are hard to maintain.

Modular-driven framework

In a modular-driven test framework, testers disintegrate larger test cases into smaller modules for individual testing. The individual test scripts can also be clubbed together to create master test scenarios. It also ensures the reusability of test scripts.

Advantage: Because of its modular nature, the entire framework needn’t be altered each time a change is required.

Disadvantage: Programming expertise is mandatory to create and use this framework.

Behavior-driven framework

Also known as the behavior-driven development (BDD) framework, the behavior-driven test framework is an agile testing framework that designs test suites to validate application specifications provided to the user. In other words, if an application promises a particular specification to the end-user, the BDD framework ensures the application testing results confirm the expected outcome.

Advantage: It creates easily readable test scripts and helps non-technical decision makers make changes in the framework as needed.

Disadvantage: It involves a lot of back and forth between the end user and the software testers and is impractical to be used for short term projects.

Data-driven framework

For multiple application test suites that need to use the same set of data as input for their tests, data-driven testing frameworks help maintain separate sources for data and test scripts. Multiple data sources can be accessed to be used for different test scenarios, reducing the need to create multiple test scripts.

Advantage: It is very time-efficient since tests can be framed using multiple data sets.

Disadvantage: Programming expertise is needed since multiple sources of data need to be verified before integration.

Keyword-driven framework

Also known as table-driven testing, this particular testing framework uses action-based keywords such as click, login, verify link, etc. The keyword-driven testing framework maps the keyword repository to test data and creates scripts based on the application requirements.

Advantage: Test scripts are reusable and can be developed independent of the application.

Disadvantage: It is not a very scalable framework since keywords need to be defined during the initial set up.

Hybrid framework

Hybrid test automation frameworks are created by combining one or more of the frameworks mentioned above, mitigating their weaknesses, and combining their strengths. Hybrid frameworks are very useful in today’s agile software development environment since they provide enough flexibility to adapt to new features and technologies.

How to create a test automation framework

Building a robust test automation framework is crucial for an organization to focus on efficient test-driven development and build functional tests for a variety of web applications. Testers need to keep in mind the following steps while writing an efficient test automation framework.

Organizing your assets

Planning the test suites and cases to be included in the test automation framework is essential. It helps organizations to revisit the test suites for any altercation or update when necessary. It also assists developers in reusing the test suites as necessary.

Understanding your applications

A detailed understanding of your business applications is necessary before setting up a test automation framework. If developers understand the internal architecture and basic functionalities of an application under test, they can create better frameworks designed to test them.

Gathering relevant data

Understanding how the testing environment works and how you can set up your tests to run efficiently in any of those environments is a necessary step to undertake while creating a test automation framework. Additionally, your test data needs to be stored in a separate repository from your test suites to access them independently for any project.

Creating smoke tests

A smoke test is defined as a preliminary test done over an application or a user-interface to check if the basic functionalities are in place. Creating smoke test suites is important when building a test automation framework since they are the first line of defense for any bugs or build issues your applications might encounter.

Setting up error logging

For every failure or issue encountered in a test suite appropriate logging and recording of error messages, process logs, and actions taken should be a priority. Automated reporting can be a major help in case a test fails unexpectedly.

Benefits of test automation framework

It’s a world of machine intelligence and supervised learning. Test automation frameworks leverage the power of technology to improve software production and quality. Let’s take a deep dive into the most common benefits that they provide and how they help organizations.

Efficiency

Test automation frameworks ensure an efficient way of creating, managing, and running test suites by automating the test scripts. They help improve the test effectiveness by reducing their runtime, increasing scalability, and detecting issues faster.

Consistency

With strict test design and code standards in place, test automation frameworks ensure consistency in coding standards throughout the organization. This helps in implementing code reusability for multiple projects once a particular snippet of code is approved by the system.

Lesser manual efforts

Automation frameworks ensure lesser manual efforts and in turn, give lesser chances to human errors. Any discrepancies related to different coding standards or time constraints can be resolved by using a test automation framework since it doesn’t require much human intervention.

Reporting

Test automation frameworks have reporting modules that assist them in creating comprehensive error reports. This gives developers a precise view of what applications went wrong and where the issue is detected.

Challenges of test automation framework

Building a test automation framework comes with its own set of challenges that software developers and testers need to keep in mind. This is essential to ensure that the decision to onboard an automation framework is justified in terms of business ROI and resource handling. 

Let’s take a look at the most common challenges posed for test automation frameworks.

Error handling

For ever-changing test data, multiple errors might pop up at any point in the software development stage. Though test automation frameworks are trained to take care of commonly occurring errors, complex test scenarios may involve errors spanning multiple applications and can cause faulty automation scenarios for our framework.

Cost of automation

Test automation frameworks are intricate software. It’s expensive to build them from scratch, which is often the case. Businesses need to take into consideration the developer cost, infrastructure changes, and regular maintenance overhead.

Scalability

Test automation frameworks need to be scalable with changing test environments and your company’s IT infrastructure. They need to be programmed to support a variety of applications and allow testers to use them for a multitude of test scripts.

Choosing the right test automation framework

There is no wrong testing framework, there is just one that works the best for you and your organization. Each business has its own tailored needs and the test automation framework they are adopting needs to fit in smoothly with them.

Understand project requirements

Project specifications such as team bandwidth, possible environments on which the project needs to run, and future scope of the project are important parameters to consider while choosing a test automation framework.

Understanding your project requirements thoroughly helps you determine the type of framework you need for an application and whether you should go for a combination of frameworks if needed.

Conduct market research

Creating a test automation framework is a crucial decision for any business and adequate market intelligence is necessary to settle on the right one. The right mix of open-source frameworks such as Selenium or Appium and commercial frameworks such as TestComplete is the way to go for most organizations. 

Take inputs from all stakeholders

A test automation framework is a set of common testing tools and libraries that are supposed to be used across teams. Taking inputs from all stakeholders is important while settling on one framework for the organization. Teams that are going to use and reap the advantages of a test automation framework need to communicate their priorities and basic application necessities.

Align with business goals

The ultimate goal of a test automation framework is to make software development easier for better business. Aligning the test automation framework strategy with the business objectives of an organization is important. The framework strategy should be complementing the software development timelines of the organization and be beneficial financially in the long run.
