Introduction to Codecov

Codecov is a popular code coverage tool that helps developers ensure their codebase is thoroughly tested by providing insightful coverage reports. This introduction will guide you through the basics of Codecov and demonstrate various APIs complete with code snippets, followed by a sample app implementation.

Getting Started

Codecov can be easily integrated with numerous CI/CD services, offers detailed reports, and ensures that your code quality is maintained to the highest standards. Below are some useful API examples that showcase how to efficiently utilize Codecov.

API Examples

1. Upload Reports

This API allows you to upload coverage reports to Codecov.

curl --request POST \
  --url https://codecov.io/upload/v4 \
  --header 'Content-Type: application/json' \
  --data '{
    "token": "your_repo_token",
    "commit": "commit_sha",
    "reports": "base64_encoded_coverage_report"
  }'

2. Get Repository Coverage

This API retrieves the coverage data for a specified repository.

curl --request GET \
  --url https://codecov.io/api/v2/github/{owner}/{repo} \
  --header 'Authorization: Bearer your_access_token'

3. S3 Upload

An example of uploading coverage data directly to an S3 bucket.

curl --request PUT \
  --url https://s3_bucket_url \
  --header 'Content-Type: text/plain' \
  --data '@/path/to/coverage.txt'

Sample App Using Codecov APIs

Here is a simple application demonstrating the usage of the above APIs to automate the upload and retrieval of coverage reports.

import requests

def upload_coverage():
  url = 'https://codecov.io/upload/v4'
  headers = {'Content-Type': 'application/json'}
  data = {
    "token": "your_repo_token",
    "commit": "commit_sha",
    "reports": "base64_encoded_coverage_report"
  }
  response = requests.post(url, headers=headers, json=data)
  if response.status_code == 200:
      print("Coverage report uploaded successfully")
  else:
      print("Failed to upload coverage report")

def get_coverage():
  url = 'https://codecov.io/api/v2/github/{owner}/{repo}'
  headers = {'Authorization: Bearer your_access_token'}
  response = requests.get(url, headers=headers)
  if response.status_code == 200:
      print("Repository coverage data: ", response.json())
  else:
      print("Failed to retrieve coverage data")

if __name__ == "__main__":
  upload_coverage()
  get_coverage()

The application uses the requests library in Python to interact with the Codecov APIs, simplifying the process of managing code coverage data.

By integrating Codecov into your project, you ensure that your code quality remains high, as continuous monitoring provides real-time feedback on the extent of code coverage.
