In a scenario where API endpoints change frequently, how can Postman assist in maintaining test accuracy?
- Change the test scripts each time
- Rely on manual testing
- Update the documentation only
- Use variables and environments
Postman allows the use of variables and environments, helping maintain test accuracy even when API endpoints change frequently.
What is the primary objective of performance testing in web services?

When performing integration testing, what is typically the first step?
- Check the user interface for consistency
- Integrate the components and test their interaction
- Test the individual units in isolation
- Validate the overall functionality of the web service
The typical first step in integration testing is to test the individual units in isolation before validating their interaction as a whole.
