Choosing a Continuous API Testing Solution: A Guide for Developers, QA and DevOps

API Testing

With APIs becoming a core component of modern applications, - DevOps, QA, developers and API architects need to ensure their reliability. However, testing and monitoring APIs requires overcoming complex integrations, coverage issues, security risks, scalability challenges, and more. In this blog post, we propose a solution to these challenges. 

Read on to learn API testing practices and how BlazeMeter’s continuous API testing platform ensures improved code quality while empowering customers and teams.

What is API Testing?

API testing is a type of software testing for verifying and validating APIs. This is done by sending calls to the API, getting the output, and assessing the system's response against various outcomes. Outcomes could include data accuracy, HTTP status codes, error codes when API returns a fault, and response times. With API testing, engineers can ensure that the APIs meet expectations for functionality, reliability, performance, and security.

What is API Monitoring?

API monitoring is the observance of production APIs’ performance. This practice helps identify issues like increased latency, reduced throughput, and unexpected downtime in APIs that can affect the end-user experience. With API monitoring, engineers can ensure APIs are available, functional, and performing within expected parameters.

The Role of API Testing and Monitoring in the Digital Landscape

Over 90% of developers use APIs and 61% of IT leaders say that APIs help build better digital experiences and products. This makes APIs integral to modern applications. Effective testing and monitoring lead to:

  • High functioning and performing APIs under all conditions
  • A better user experience
  • Faster time-to-market
  • Improved security posture
  • Reduced costs
  • Lower risk of failure

These are vital to the success of these applications.

Top Challenges with API Testing and Monitoring

Despite the importance of API testing and monitoring, many organizations are still finding it challenging to evaluate APIs and ensure they can support development and business needs. The main challenges include:

  • Complex Integrations - Complex and varied systems make it difficult to ensure accurate, comprehensible and reliable testing 
  • Comprehensive Coverage - Ensuring complete test coverage that validates all aspects of API functionality and error handling.
  • Evolving APIs - Keeping test suites updated with frequent API changes and versioning.
  • Performance Under Load - Guaranteeing API performance under high traffic and various use case scenarios.
  • Security Risks - Addressing and mitigating security vulnerabilities to prevent unauthorized access and data breaches.
  • Real-time Detection - Identifying and resolving production issues with APIs in real time.
  • Third-Party Dependencies - Managing the added complexity of third-party APIs and their impact on system performance.
  • Scalability - Scaling monitoring strategies to keep pace with the increasing number and usage of APIs.

BlazeMeter’s Continuous API Testing and Monitoring Capabilities

BlazeMeter offers continuous API testing and monitoring services as part of the complete BlazeMeter Continuous Testing Platform. With thousands of brands using BlazeMeter, more than 19 million API uptime and data validation checks are run per day.

BlazeMeter’s continuous API testing capabilities include:

Real-Time API Performance Monitoring

BlazeMeter enables teams to understand their API behavior in real time. By integrating with open-source and third-party tools like JenkinsPagerDuty, and Slack, BlazeMeter provides timely notifications about API issues​​. These issues are monitored throughout the entire SDLC, from early development through production, API. 

Data Validation and Complex Workflow Testing

BlazeMeter offers robust data validation capabilities. Users can verify that APIs return the correct data and chain API requests to create tests for complex workflows. This functionality includes checking for specific status codes, HTTP headers, and JSON or XML properties, or creating custom validation rules using a built-in JavaScript script engine​​.

"Our API has become a vital part of the business. BlazeMeter’s API Monitoring allows us to set up complicated API monitors that include our OAuth layer with just a few clicks." Jim Naylor, Director of Product Management, Edmunds.com

Continuous API Testing Platform

BlazeMeter provides a single platform to test all APIs, from development to production, without switching between multiple tools. It supports the reuse of functional tests for performance, load, and API monitoring, and facilitates team collaboration with shareable monitor links​​.

"Since we began using BlazeMeter’s API Monitoring, our average support time is a fraction of what it used to be. When a partner reports a bug, we can fix it immediately." Troy Miller, API Product Manager, uShip

Global API Performance Monitoring

BlazeMeter enables global API performance monitoring from 19 different locations, ensuring a high-quality API experience for users and customers worldwide. This helps identify potential issues or slowdowns over time​​.

*The fact that BlazeMeter’s API Monitoring has multiple locations across the globe from which you can monitor is very valuable so that we can proactively solve even the most under-the-radar issues." Chris Knowles, Technology Director, Omnifone

Enhanced Application Quality with Shift-Right Approach

BlazeMeter supports a shift-right approach to API testing, which means APIs are monitored across the entire development life cycle. This approach helps increase API resiliency, find and fix bugs faster, and is a complementary strategy to continuous testing, especially when combined with load and performance testing​​.

"Uptime and performance are vital to us. BlazeMeter’s API Monitoring reduces development time and ensures optimal performance of our API at all times." Sara Cowie, Head of Customer Acquisition, Syncano
