Introduction
TestComplete, developed by SmartBear, is a comprehensive test automation tool designed to cater to a wide array of testing needs, including functional, GUI, unit, regression, and most importantly, API testing. TestComplete is well-regarded in the testing community for its ease of use and flexibility, making it a popular choice among testers and QA professionals.
While primarily known for its GUI testing capabilities, TestComplete has gained recognition for its ability to automate API tests, a critical component in today’s software ecosystem. APIs are the backbone of modern applications, and ensuring they function correctly is vital for seamless software operations. TestComplete provides a user-friendly interface along with advanced features for creating, running, and managing API tests, which makes it an ideal tool for both novice and experienced testers.
Features
TestComplete offers a robust set of features that make it suitable for diverse API testing scenarios. Here’s an overview of its key functionalities:
a) Cross-Technology API Testing
TestComplete supports testing of both REST and SOAP APIs. This flexibility is essential in environments where different technologies coexist, making it a versatile tool for API testing. It allows you to validate the functionality, performance, and security of APIs, ensuring that the responses are correct, consistent, and adhere to the expected behavior.
b) Keyword-Driven Testing
One of TestComplete’s hallmark features is its keyword-driven testing approach. This method allows testers to create automated tests by simply selecting actions from a list of predefined keywords, making API testing accessible even for individuals who are not proficient in scripting. This can significantly speed up the development of automated tests and reduce the learning curve for new team members.
c) Scripted Testing
For more advanced testers or developers, TestComplete offers the flexibility of scripted testing using multiple languages like Python, JavaScript, VBScript, and JScript. This scripting capability allows users to create more complex API tests and perform sophisticated validation scenarios, including handling dynamic data, response validation, and more.
d) Automated Test Management
TestComplete provides features for managing and maintaining large API test suites with ease. It allows you to reuse tests, group them logically, and run tests in batches. The tool also offers version control integration to keep track of changes and maintain test history, making it ideal for teams working in agile environments.
e) Data-Driven Testing
TestComplete supports data-driven testing, allowing testers to input data from various sources like Excel, CSV, or databases and use that data to perform comprehensive API testing. This helps in validating APIs against a wide range of input scenarios, ensuring they behave as expected in all conditions.
f) CI/CD Integration
In modern software development, integrating testing tools into Continuous Integration/Continuous Deployment (CI/CD) pipelines is essential. TestComplete supports integration with popular CI/CD tools such as Jenkins, Azure DevOps, and Bamboo. This ensures that API tests can be executed as part of automated builds and deployments, facilitating continuous testing and quicker feedback loops.
g) Visual API Tests
TestComplete provides a visual environment to create and execute API tests without writing any code. This feature is particularly useful for testers who are more comfortable working in a graphical interface rather than a code-based environment. It simplifies the process of creating API tests by using a drag-and-drop interface, thus reducing the complexity of test creation.
h) Reporting and Analytics
The tool provides detailed test reports and logs that help identify issues quickly. TestComplete also includes analytics tools that give insight into the overall quality of the API under test. These reports and dashboards can be customized and shared with team members, making it easier to communicate test results and track the progress of the testing effort.
Pros
a) Easy to Use
TestComplete’s combination of keyword-driven testing and its visual interface makes it a great tool for both novice and advanced testers. Beginners can start with its intuitive interface, while experienced users can take advantage of the advanced scripting capabilities.
b) Multi-Technology Support
One of TestComplete’s significant advantages is its support for a wide range of technologies and platforms, including APIs, desktop applications, web applications, and mobile apps. This makes it an all-in-one solution for teams working on diverse projects.
c) Seamless Integration with CI/CD Tools
TestComplete’s ability to integrate with leading CI/CD tools like Jenkins and Azure DevOps makes it an excellent option for teams practicing continuous testing. It allows for the automation of API tests as part of the build and deployment process, ensuring quicker releases with fewer bugs.
d) Cross-Browser Testing
In addition to API testing, TestComplete offers cross-browser testing capabilities. This is especially useful for teams working on web applications, allowing them to verify API behavior across multiple browsers.
e) Reusability of Test Scripts
The tool offers excellent reusability features, allowing testers to reuse scripts and objects across different tests. This can significantly reduce test development time and ensure consistency across various tests.
f) Excellent Community and Support
Being part of the SmartBear family, TestComplete benefits from a robust community and extensive support options. This includes forums, tutorials, documentation, and customer support, making it easier to resolve issues and learn best practices.
Cons
a) Steep Learning Curve for Advanced Features
While the keyword-driven testing feature makes it accessible for beginners, more advanced features, such as scripting and managing complex tests, can have a steep learning curve. Testers may need significant time to master the tool’s advanced functionalities.
b) Expensive Licensing Model
TestComplete’s pricing can be prohibitive, especially for small teams or startups. While the tool offers extensive capabilities, its cost might not be justifiable for teams only needing basic API testing features.
c) Performance Issues with Large Projects
In environments where the tool is used for large-scale projects, some users have reported performance degradation. TestComplete can slow down when dealing with extensive test suites, which may impact overall productivity.
d) Limited API-Specific Features
While TestComplete provides API testing capabilities, it lacks some of the advanced API-specific features offered by dedicated API testing tools like Postman or SoapUI. For example, its API documentation generation and mocking features are not as robust.
Usage and Links
a) Basic Usage Example
To create a simple API test in TestComplete, you can follow these steps:
- Open TestComplete and create a new project.
- Add an API test item by navigating to Add New Item and selecting Web Service.
- Specify the API endpoint (either REST or SOAP).
- Use the visual editor to build requests and specify the parameters for the API.
- Define assertions to validate the response, such as status code, headers, or body content.
You can run this test as part of a larger test suite and integrate it into your CI/CD pipeline for continuous testing.

Pricing
TestComplete operates under a commercial license, and its pricing is tiered based on the features and number of users. It offers two primary plans:
a) TestComplete Base
This package includes essential testing capabilities for desktop, mobile, and web applications. It starts at approximately $6,095 per year, making it a relatively expensive solution for small teams.
b) TestComplete Pro
The Pro version offers more advanced features, including support for multiple platforms and environments, along with enhanced reporting, parallel execution, and integration capabilities. The price for this plan can go up significantly based on the number of users and add-ons.
