# TestRail API credentials
url = 'https://your_testrail_instance/index.php?/api/v2/add_case/1'  # Replace '1' with your test suite ID
username = 'your_username'
password = 'your_password'

# New test case data
data = {
    'title': 'New Test Case',
    'template_id': 1,
    'type_id': 1,
    'priority_id': 2,
    'estimate': '1m',
    'refs': 'RF-1, RF-2'
}

# Make the API request
response = requests.post(url, auth=(username, password), headers={'Content-Type': 'application/json'}, data=json.dumps(data))

# Check the response
if response.status_code == 200:
    print('Test case added successfully.')
else:
    print('Failed to add test case:', response.content)

5. Write a script to update the status of a test run based on external test results using the TestRail API.

To update the status of a test run in TestRail based on external test results, interact with the TestRail API. This involves making HTTP requests to the appropriate endpoints, typically using a library like requests in Python. The key steps include authenticating with the API, sending the request to update the test run, and handling the response.

Example:

import requests

def update_test_run_status(base_url, username, api_key, run_id, status_id):
    url = f"{base_url}/index.php?/api/v2/update_run/{run_id}"
    headers = {
        "Content-Type": "application/json"
    }
    data = {
        "status_id": status_id
    }
    response = requests.post(url, headers=headers, json=data, auth=(username, api_key))
    
    if response.status_code == 200:
        print("Test run status updated successfully.")
    else:
        print(f"Failed to update test run status: {response.status_code}")

# Example usage
base_url = "https://your_testrail_instance"
username = "your_username"
api_key = "your_api_key"
run_id = 123
status_id = 1  # Status ID for 'Passed'

update_test_run_status(base_url, username, api_key, run_id, status_id)

6. Write a script to generate a custom report from TestRail data.

To generate a custom report from TestRail data, use the TestRail API to fetch the necessary data and then process it according to your requirements. Below is an example using Python.

First, install the requests library if you haven’t already:

pip install requests

Here is a simple script to fetch test case data from TestRail and generate a custom report:

import requests
import json

# TestRail API credentials
url = 'https://your_testrail_instance/index.php?/api/v2/get_cases/1'
headers = {
    'Content-Type': 'application/json'
}
auth = ('your_username', 'your_api_key')

# Fetch data from TestRail
response = requests.get(url, headers=headers, auth=auth)
test_cases = response.json()

# Generate custom report
report = []
for case in test_cases:
    report.append({
        'id': case['id'],
        'title': case['title'],
        'status': case['status_id']
    })

# Print or save the report
print(json.dumps(report, indent=4))

In this script, authenticate with the TestRail API, fetch test case data, and generate a custom report by extracting relevant fields.

7. How would you integrate automated tests with TestRail?

Integrating automated tests with TestRail involves using TestRail’s API to programmatically update test results. This allows for seamless integration of test automation frameworks with TestRail, ensuring that test results are automatically recorded and tracked.

To integrate automated tests with TestRail, follow these steps:

• Use TestRail’s API to create and manage test cases and test runs.
• Execute your automated tests using your preferred test automation framework.
• After test execution, use the API to update the test results in TestRail.

Here is a concise example using Python to demonstrate how to update test results in TestRail:

import requests

class TestRailAPI:
    def __init__(self, base_url, username, password):
        self.base_url = base_url
        self.auth = (username, password)

    def add_result_for_case(self, run_id, case_id, status_id, comment):
        url = f"{self.base_url}/index.php?/api/v2/add_result_for_case/{run_id}/{case_id}"
        data = {
            "status_id": status_id,
            "comment": comment
        }
        response = requests.post(url, json=data, auth=self.auth)
        return response.json()

# Example usage
testrail = TestRailAPI('https://your_testrail_instance', 'username', 'password')
result = testrail.add_result_for_case(run_id=1, case_id=1, status_id=1, comment='Test passed')
print(result)

In this example, the TestRailAPI class is used to interact with TestRail’s API. The add_result_for_case method updates the test result for a specific test case within a test run.

8. What strategies would you use to optimize TestRail performance for large-scale projects?

10. What are the API rate limits in TestRail, and what are some best practices for using the API efficiently?

API rate limits are restrictions set by an API provider to control the number of requests a client can make to the server within a specified time frame. These limits ensure fair usage and prevent abuse that could degrade performance.

In TestRail, the API rate limits are designed to keep the system responsive and stable for all users. As of the latest information, TestRail imposes a rate limit of 180 API requests per minute per user. Exceeding this limit will result in the API returning a 429 Too Many Requests status code, and the client will need to wait before making additional requests.

To use the TestRail API efficiently, consider these best practices:

• Batch Requests: Whenever possible, batch multiple operations into a single request to reduce the number of API calls.
• Rate Limiting: Implement client-side rate limiting to ensure your application does not exceed the allowed number of requests per minute.
• Retry Logic: Implement retry logic with exponential backoff to handle 429 status codes gracefully.
• Efficient Data Handling: Fetch only the necessary data by using filters and pagination to minimize data transfer.
• Cache Responses: Cache responses for frequently requested data to reduce the number of API calls.
