5 Ways Automated Integration Testing Can Boost Your Development Velocity

5 Ways Automated Integration Testing Can Boost Your Development Velocity

Key Highlights

In this blog, we cover the following highlights:

  1. Integration testing is the best way to test service-level modules, aka microservices.

  2. Integration testing combines with automation can achieve higher velocity, and deliver more reliable software faster.

  3. It also achieve makes the development teams respond more swiftly to market demands or changes.

  4. Tools like HyperTest simplifies microservices testing through its RECORD and REPLAY modes, alongside its ability to test stateful applications.

This guide is your optimal solution for mitigating any such obstacle and building a robust test suite for your microservices.

Integration testing is crucial when it comes to microservices. The division of one entity into smaller components or modules and checking them if they all work together in sync as intended is the purpose of integration tests.

Situated at the middle layer of the testing pyramid, integration testing focuses on validating the flow of data and functionality between various services. It primarily examines the input provided to a service and the corresponding output it generates, verifying that each component functions correctly when integrated with others.

The integration of automation into the realm of integration testing significantly enhances its effectiveness. Automated integration tests offer numerous advantages, including improved code coverage and reduced effort in creating and maintaining test cases. This integration testing automation promises enhanced return on investment (ROI) by ensuring thorough testing with minimal manual intervention.

This article is your go-to guide in case you are unaware of this combination and the enormous benefits that it brings along. Let’s dive right in:

1️⃣ Increased Test Coverage and Reliability

Automation allows for a broader range of tests to be executed more frequently, covering more code and use cases without additional time or effort from developers. This comprehensive coverage ensures more reliable software, as it reduces the likelihood of untested code paths leading to bugs in production.

💡 With a more robust test suite, developers can make changes knowing they are less likely to cause disruptions.

✅ Achieve Up To 90% Test Coverage With HyperTest

HyperTest can help you achieve high >90% of code coverage autonomously and at scale. It’s record-and-replay capabilities can reduce your testing efforts of 365 days to less than a few hours.

HyperTest seamlessly integrates with microservices through an SDK, automatically capturing both inbound requests to a service and its outbound calls to external services or databases. This process generates comprehensive test cases that include all aspects of a service's interactions.

2️⃣ Reduced Time In Writing and Maintaining Test Cases

Furthermore, the efficiency brought by automation greatly reduces the time and effort required in writing and maintaining test cases.

💡 Modern testing tools and frameworks offer features that streamline test creation, such as reusable scripts and record-and-playback capabilities, while also simplifying maintenance through modular test designs.

This not only accelerates the development cycle but also allows for rapid adaptation to changes in application code or user requirements.

No need to write a single line of code with HyperTest

When 39% of companies are interested in using codeless test automation tools, then why to still pursue tools that doesn’t gives you the freedom of codeless automation really.

HyperTest is a simple to setup tool, requiring only 4 lines of code to be added to your codebase, and viola, HyperTest’s SDK is already working!

3️⃣ Improved Speed to Run Test Cases

The speed at which automated tests can be run is another critical advantage. Automated integration tests execute much faster than manual counterparts and can be run in parallel across different environments, significantly cutting down the time needed for comprehensive testing.

This swift execution enables more frequent testing cycles, facilitating a faster feedback loop and quicker iterations in the development process.

✅ Autonomous Test generation in HyperTest paces up the whole process

By eliminating the need to interact with actual third-party services, which can be slow or rate-limited, HyperTest significantly speeds up the testing process. Tests can run as quickly as the local environment allows, without being throttled by any external factors, which is the case in E2E tests.

4️⃣ Improved Collaboration and Reduced Silos

Enhanced collaboration and reduced silos are also notable benefits of adopting automated integration testing. It promotes a DevOps culture, fostering cross-functional teamwork among development, operations, and quality assurance. With automation tools providing real-time insights into testing progress and outcomes, all team members stay informed, enhancing communication and collaborative decision-making.

✅ HyperTest instantly notifies you whenever a services gets updated

HyperTest autonomously identifies relationships between different services and catches integration issues before they hit production. Through a comprehensive dependency graph, teams can effortlessly collaborate on one-to-one or one-to-many consumer-provider relationships.

And whenever there’s a disruption in any service, HyperTest lets the developer of a service know in advance when the contract between his and other services has changed, enabling quick awareness and immediate corrective action.

5️⃣ Facilitates Continuous Integration and Deployment (CI/CD)

Lastly, automated integration testing is pivotal for facilitating continuous integration and deployment (CI/CD) practices. It seamlessly integrates testing into the CI/CD pipeline, ensuring that code changes are automatically built, tested, and prepared for deployment. This capability allows for new changes to be rapidly and safely deployed, enabling organizations to swiftly respond to market demands and user feedback with high-quality software releases.

✅ Easy Integration of HyperTest with over 20+ CI/CD Tools

HyperTest offers effortless integration with a wide range of Continuous Integration and Continuous Deployment (CI/CD) tools, including popular options like Jenkins, GitLab CI/CD, Travis CI, CircleCI, and many more. This seamless integration simplifies the incorporation of automated testing into the existing development workflow, ensuring that testing is seamlessly integrated into the deployment pipeline.

By incorporating automated integration testing into their workflows, development teams can achieve higher velocity, deliver more reliable software faster, and respond more swiftly to market demands or changes.

HyperTest can accelerate and help you achieve your goal of higher coverage with minimal test case maintenance, click here for a walk-through of HyperTest or contact us to learn more about its working approach.
