Pricilla Bilavendran's session at the Testμ Conference 2022 emphasized the critical importance of API testing in the context of modern software development, particularly following the digital transformation accelerated by the pandemic. She discussed the "API revolution" and highlighted that API testing is now a necessity, especially for applications built on microservices architecture. Pricilla detailed various types of API testing, including validation, functional, and security testing, and stressed the significance of addressing API vulnerabilities like broken authentication and data exposure. She advocated for continuous monitoring and integrating security test cases into routine testing to enhance API security. Additionally, Pricilla underscored the role of performance testing in ensuring application efficiency and customer satisfaction, while also highlighting the growing need for API automation and integration with CI/CD pipelines. The session concluded with a Q&A where Pricilla addressed the influence of cloud infrastructure on API performance and security, the differences in testing standard versus custom APIs, and the potential impact of AI and ML on managing API security threats.
