Functional Testing in SOAP UI :
- Focus: Verifies that the API behaves as expected under normal conditions. It checks if the API performs its intended functions correctly.
- Scope: Tests individual functionalities, such as:
- Correctness of data processing
- Proper handling of different input scenarios
- Validation of responses (status codes, data format, etc.)
- Authentication and authorization mechanisms
- Techniques:
- Creating TestCases with TestSteps (Request, Response, Assertions)
- Data-driven testing using Data Sources
- Verifying expected outcomes using Assertions (XPath Match, Script Assertions)
- Goal: Identify bugs, defects, and unexpected behavior in the API's functionality.
-
Load Testing in SOAP UI :
- Focus: Evaluates the performance of the API under heavy load. It determines how the API behaves when multiple users access it concurrently.
- Scope: Tests the API's ability to handle a large number of requests simultaneously. It assesses:
- Response times under different load levels
- System stability and resource utilization
- Potential bottlenecks and performance degradation
- Techniques:
- Creating LoadTests from existing TestCases
- Simulating multiple virtual users
- Monitoring key performance indicators (KPIs) like response times, throughput, and error rates
- Goal: Identify performance bottlenecks, ensure scalability, and optimize the API for high traffic.
