Execute and analyze API tests

Zoho QEngine lets users check the components of API requests to test for the functionality, security, and reliability of their applications and websites.

Customization and execution of API requests

For API testing, multiple API requests can be created and managed in a single window, to be executed at the click of a button. There are five different HTTP methods, namely GET, POST, PUT, PATCH, and DELETE, to perform actions via requests. Each request can have further customizable elements—parameters, authentication, header, and body.

Checking authentications via API testing

Connections to third-party services extend the functionality of existing applications or websites. Zoho QEngine enables users to connect securely with other Zoho or third-party services via different API authentication methods—API key, Basic, OAuth1, and OAuth2.


Assertions to validate API requests

Assertions form an integral part of API testing, by comparing API responses against reference values for the corresponding queries, to check if user-defined conditions are met. Zoho QEngine has the functionality to validate parts of responses in different formats, like JSON or XML. Any API request can have multiple assertions, all of which need to be true for the test to pass.

Continuous API testing with variables

Variables can be used to store specific values from responses, to be referenced in-body or passed as parameters for continuous testing of API requests. Zoho QEngine has a variables repository to store variables with a global scope—global variables and environment variables, which store different values for the environment.

Smart analysis of API tests

After execution, each API request in Zoho QEngine returns a detailed response comprising test results, status code, response time, response body, response header, and request details. Analyzing these responses provides valuable insights on the stability and reliability of the application or website.

Scheduled API testing

Automation eliminates the need for a QA engineer to execute test cases manually, especially outside office hours. API requests inside Zoho QEngine's test suites can be automated to execute at a set time, and can be run sequentially or simultaneously, based on the availability of parallel tests.

Frequently asked questions

1. What is API testing?

Application programming interfaces (APIs) enable communication and data exchange between various services and applications. API testing checks whether the application or website can communicate with the server and other services effectively.

2. What are the different types of API testing?

Validation testing, functional testing, UI testing, load testing, runtime/error detection, security testing, penetration testing, fuzz testing, and interoperability and WS compliance testing are all types of API testing.

3. What are the best API testing practices?

Always test APIs for conditions emulating real-world scenarios, and ensure that records are maintained for API requests and responses. Automate API tests which can't be done using unit or integration tests. Using a comprehensive testing tool like Zoho QEngine, which manages every aspect of API testing, makes this process much easier.
