FAQ
What do you need to start testing my API?
Please provide the API base URL, endpoint documentation or Swagger/OpenAPI link, authentication details, expected behavior, and access to a test environment. Do not send production credentials.
What is considered one API endpoint?
One endpoint means one HTTP method and route combination. For example, GET /users and POST /users are counted as two separate endpoints.
Do you provide automated API tests?
Yes. The Standard and Premium packages include automated API tests using Java, RestAssured, and JUnit 5. The Basic package includes manual Postman testing.
Will I receive the test files and report?
Yes. Depending on the package, you will receive a structured test report, screenshots, a Postman collection, and/or reusable automated test code.
Do you perform performance or security testing?
No. This Gig focuses on functional REST API testing. Load testing, penetration testing, and full security audits are not included.
