Unifying API and UI Testing with ReadyAPI and TestComplete to Maximize Product Quality

The world is filled with products and services that power our everyday lives. As consumers, we all appreciate the benefits of a great product. But think back to the last time you used an app or website that was slow to load or failed to open. Experiences like that can leave a lasting negative impression and hurt a business’s reputation.

To deliver a great customer experience, every product must be thoroughly tested from frontend to backend. Two tools work in perfect harmony to achieve this: ReadyAPI and TestComplete. Together, they provide full-stack coverage by combining powerful API testing with robust UI automation to ensure your products perform flawlessly. Using them side by side can elevate your product quality and create lasting positive impacts for your customers.

The Tools

ReadyAPI is SmartBear’s all-in-one platform for on-premises API testing. APIs are the lifeblood of modern applications, and ensuring they behave as expected under all conditions is critical. ReadyAPI offers a suite of modules that lets you cover every aspect of API testing:

• ReadyAPI Test handles end-to-end functional testing and workflows to ensure your APIs return the right responses under the right conditions. You can also create security tests to provide consumers of your APIs with a safe and reliable experience.
• ReadyAPI Performance simulates load and stress scenarios, helping you identify bottlenecks before your users do.
• ReadyAPI Virtualization allows you to create mock services, enabling isolated testing even when dependent APIs aren’t available.

It supports an impressive range of protocols including REST, SOAP, GraphQL, JDBC, JMS, and more, making it a highly versatile tool.

TestComplete is SmartBear’s all-in-one platform for functional UI and automated testing.
User interfaces are the gateway to modern applications, and ensuring they work flawlessly across different devices, browsers, and environments is essential. TestComplete provides a comprehensive set of capabilities that let you cover every aspect of UI and functional testing:

• Cross-Platform UI Testing supports web, desktop, and mobile applications, allowing you to validate consistent functionality and user experience across all major platforms.
• Record and Replay functionality makes it easy to create automated tests without extensive coding knowledge, while still offering powerful scripting options in languages like Python, JavaScript, and VBScript for advanced workflows.
• Object Recognition Engine uses AI-powered visual recognition and property-based detection to handle dynamic and frequently changing UI elements with precision.
• Data-Driven Testing enables you to run the same test with multiple sets of input data, ensuring broad coverage and reducing repetitive work.

With support for a wide variety of technologies, including .NET, Java, HTML5, WPF, and mobile frameworks, TestComplete is a versatile solution for building, maintaining, and scaling reliable automated tests.

Tool Synergy

ReadyAPI and TestComplete enable the creation of robust API and UI tests respectively. However, the combined power of these tools using their integrations are significantly powerful in designing spectacular products.

The ReadyAPI process will look like this:

1. Create a Functional Test with a Test Suite and Test Case.
2. Import your Data Source using the built-in Data Source Test Step.
3. Create a Data-Driven Functional Test using your imported Data Source.
4. Add a TestComplete Test Step to begin testing the UI using the same data from ReadyAPI.
5. Run the Test Suite

The TestComplete process will look like this:

1. Create a Keyword Test.
2. Import your Data Source using the built-in Data Source Test Step.
3. Create a Data-Driven Keyword Test using your imported Data Source.
4. Add a ReadyAPI Test to begin testing the API using the same data from TestComplete.
5. Create an Execution Plan from the Keyword Test and ReadyAPI Test

Next Steps

With the integration between ReadyAPI and TestComplete successfully integrated, you can enhance your projects even further with other SmartBear tools:

• ReadyAPI Performance: Apply load testing to the same functional test used in the videos above to see how the API handles real-world traffic.
• ReadyAPI Virtualization: Carry out your tests on virtual APIs to remove the need for third-party API dependencies and separate release stage builds.
• TestEngine: Automate your API testing process further by running multiple projects in parallel from multiple ReadyAPI instances or CICD pipelines.
• LoadNinja: Apply load testing to the same keyword test used in the videos apply to see how the UI handles real-world traffic.
• BitBar: Emulate devices such as phones and tablets, to see how the website handles usage across different types of platforms.
• TestExecute: Automate your UI testing process further by running multiple projects in parallel from multiple TestComplete instances or CICD pipelines.

By combining ReadyAPI’s comprehensive API testing capabilities with TestComplete’s powerful UI automation, teams can achieve complete, end-to-end coverage that leaves nothing to chance. This synergy not only streamlines testing workflows but also ensures that products perform seamlessly under real-world conditions.

Delivering a flawless user experience is essential for a business’s reputation. From the reliability of your APIs to the responsiveness of your user interface, every layer of your application plays a critical role in how customers perceive your brand.

When used together, ReadyAPI and TestComplete empower teams to build higher-quality software, reduce risk, and deliver products that delight users from the first click to the last interaction creating positive, lasting impressions that drive long-term success.
