Did you know that according to a report by Sauce Labs, companies that build their test automation frameworks spend an average of 51% more time on maintenance than those that use pre-built frameworks? It means that while building a custom framework may seem like a good idea in the short term, it can lead to additional costs and resources in the long term.

When choosing between building or buying a test automation framework, it's necessary to consider factors such as the project's scope, available resources, technical expertise, and long-term maintenance and support. Below, we will delve into what test automation framework is in simple terms and when it is beneficial. We will compare the framework to a custom test automation solution and figure out which one will be the best for you.

What is a test automation framework in simple terms? 

To put it simply, think of a test automation framework as a set of building blocks, similar to a LEGO set. Just as a LEGO set provides a standard set of building blocks to build various structures, a test automation framework offers a set of guidelines and tools to automate software testing in a structured way.

With LEGO blocks, you can follow instructions to build a specific model or use your imagination to create your unique designs. Similarly, with a test automation framework, you can follow a set of guidelines and coding standards to develop automated test scripts for specific scenarios or use your expertise and creativity to design your unique test cases.

A test automation framework typically consists of a combination of tools, libraries, and coding standards that allow testers to create and maintain automated test scripts in a structured way. It helps to standardize the testing process, improve test coverage, reduce testing time, and minimize the maintenance effort required to keep the test suite up to date.

There are various test automation frameworks, each with its advantages and disadvantages. Some popular frameworks include keyword-driven, data-driven, and behavior-driven frameworks. The framework choice depends on the project's specific needs and the resources available to the testing team.

When the test automation framework is game-changing?

A test automation framework is helpful in certain situations, including:

Repetitive testing

Automating tests using a framework rather than manually running them every time can be more efficient when you need to perform the same set of tests repeatedly.

Large or complex systems

When testing large or complex systems, it can be complicated and time-consuming to manually test all functionality. Test automation framework can streamline the testing process and ensure that all aspects of the system are thoroughly tested.

Regression testing

To ensure that changes in the system have not impacted existing functionality, it is necessary to perform regression testing. Automating these tests can save time and ensure that all relevant tests are executed effectively. 

Agile development

When working in an agile development environment, it is beneficial to use a test automation framework to keep up with the fast pace of development and ensure that testing is integrated into the development process.

Improved accuracy and consistency

Automated tests are more accurate and consistent than manual ones, ensuring that all relevant scenarios are tested and reducing the risk of human error.

Framework vs. Custom test automation solution

Companies take two main approaches regarding test automation solutions: framework-based or custom-built.

Framework-based automation relies on pre-built, off-the-shelf testing frameworks such as Selenium or Postman, which provide tools and functions to automate testing tasks. These frameworks offer a standardized approach and often come with documentation, support, and a community of users. 

On the other hand, custom-built automation solutions are designed from scratch to fit the organization's specific needs. This approach offers more flexibility and can be tailored to the exact requirements of the software testing. However, designing and developing require more time and resources and might require continuous maintenance and updates. 

Here are some factors that a person needs to consider when choosing between a framework and a custom test automation solution:

Requirements

The first thing to consider is the testing requirements. Does the project require a specialized approach, or can it be done using an existing framework? If a framework already exists that satisfies the requirements, then using that framework would be more efficient than building a custom solution from scratch.

Budget

The budget is critical for building or buying a test automation framework. Creating a custom framework requires significant time, resources, and expertise. Companies must consider the cost of hiring or training staff to build and maintain the framework and the potential impact on their development timeline.

On the flip side, buying an off-the-shelf solution is often more cost-effective, as it eliminates the need for in-house development and maintenance. However, companies must also consider the long-term cost of licensing fees, support, and the potential for vendor lock-in. 

Maintenance

Frameworks are often maintained by a community of developers, so updates and bug fixes are regularly released. On the other hand, a custom solution requires ongoing maintenance and support, which can be time-consuming and expensive.

Integration

Consider how the test automation solution will integrate with other tools and systems. A framework may offer better integration with other tools, while a custom solution may require more integration effort.

The ability to customize

Building a custom framework offers the most significant degree of flexibility and control, as it might be designed to fit the exact requirements of the software being tested. It can be especially important for complex or specialized software applications. 

Alternatively, pre-built frameworks may offer limited features to suit specific testing scenarios. However, some off-the-shelf solutions may offer customization options or be more easily integrated with existing tools and processes.

When deciding whether to build or buy a test automation framework, consider the organization's expertise, resources, and specific testing needs.

Control

Building a custom framework provides a high level of control, as the testing team has complete control over the framework's design, functionality, and maintenance. It can be especially important for organizations with unique or complex testing requirements or needing strict control over their testing processes.

Conversely, buying an off-the-shelf solution may provide less control over the testing process, as the organization must rely on the functionality and features provided by the vendor. Yet, pre-built solutions offer a more standardized approach and are easier to maintain and update over time.

Which option is the most suitable for your needs?

When it comes to making a decision, each option has its advantages and disadvantages. The choice will depend on a range of factors, such as the specific testing needs of the organization, the available resources and expertise, and the overall business goals. 

Nevertheless, let's go through two key concerns and provide guidance to help you choose whether to build or purchase a pre-built test automation framework.

Creating your test automation framework will be the right decision for you if your project has the following:

Unique testing requirements

If your organization has individual testing requirements that existing pre-built solutions cannot meet, building your test automation framework is a more suitable option than trying to adapt an existing framework.

Long-term cost savings

Although building your test automation framework requires an initial investment of time and resources, it can be more cost-effective over the long term than using a pre-built solution, especially if your organization has a large or complex testing environment.

Complete control

Building your test automation framework gives you complete control over the development process, allowing you to tailor the framework to your organization's specific needs and requirements.

Integration with existing systems

If your organization has a complex IT infrastructure with many interconnected systems, building your test automation framework can allow for seamless integration and ensure that your testing processes are fully aligned with your organization's overall tech strategy

Open-source flexibility

Building your test automation framework using open-source tools can provide flexibility, customization, and the ability to contribute to the community. It also allows you to avoid vendor lock-in and licensing fees and create a framework that can be extended as your needs evolve over time.

Buying a test automation framework will be the right decision for you if your project has the following:

Tight timelines

If you are facing tight deadlines for a project and need to quickly establish a test automation framework, purchasing a pre-built solution can save you time and ensure that you can meet your deadlines.

Limited budget

If your organization has limited funds for building a custom test automation framework, purchasing a pre-built solution can be more cost-effective than developing a framework from scratch.

Need for a specific feature set

If your organization requires a particular set of features in your test automation framework, purchasing a pre-built solution that includes those features can be more efficient and cost-effective than building a custom framework from scratch.

Limited in-house expertise

If your organization doesn’t have the necessary skills or resources to develop a test automation framework in-house. Purchasing a pre-built framework can help you get up and running quickly without hiring additional staff or training existing employees.

Lack of testing experience

If your organization is new to test automation or has limited experience in this area, purchasing a pre-built framework can provide you with a proven solution that has already been tested and optimized by experts in the field.

We hope that provided details above will help you comprehend what features your organization should consider before choosing a test automation framework and consequently make the right choice that will perfectly suit your business model.
