🔧 Step-by-Step Guide: Creating API Tests in TestRigor

1. Create a New Test Suite

1. Log in to your TestRigor dashboard.
2. Click on "Create Test Suite".
3. Choose the type: API Testing.
4. Enter your API base URL (e.g., https://api.yourdomain.com) and save.

2. Write Your First API Test in Plain English

make a GET request to "/flights"
check that response status code is 200
check that response body contains "flightNumber"

Example 2: POST Request with Headers and JSON Body

make a POST request to "/login" with headers "Content-Type: application/json" and request body:
{
  "email": "user@example.com",
  "password": "secret123"
}
check that response status code is 200
check that response body contains "token"

💡 Tip: You can chain multiple validations in a single test.

🔁 Parameterization in API Tests

Want to reuse dynamic inputs or pull data from earlier steps? You can store and reference variables easily:

generate random email and save as "newEmail"
generate random password and save as "newPass"
make a POST request to "/signup" with body:
{
  "email": "{newEmail}",
  "password": "{newPass}"
}
check that response status code is 201

📂 Organizing Tests and Reusability

• Test Suites: Organize API tests into suites like Authentication, Booking, or Payments.
• Reusable Rules: Use the Rules section to define reusable logic blocks.
• Variables & Conditions: Use if, else, and saved values to create logic flows.

---

🔍 Advanced: API Testing with Authentication

make a POST request to "/auth" with body:
{
  "username": "admin",
  "password": "admin123"
}
save value of response JSON path "$.token" as "authToken"
make a GET request to "/user/data" with headers "Authorization: Bearer {authToken}"
check that response status code is 200
