OPA Test Coverage to SonarCloud Format

Example code to transform the OPA test coverage JSON report to the SonarCloud coverage report format.

Why?

SonarCloud allows collecting test coverage data to generate rich reports. Integration can be done using generic test data format.

Example

1. generate json format coverage result with --coverage and pipe it into a file
2. call python opa_coverage_to_sonarcloud.py <input json> <output xml> to generate xml format coverage report

$ opa test --coverage example > coverage.json
$ python opa_coverage_to_sonarcloud.py coverage.json coverage.xml

Output

<?xml version='1.0' encoding='utf-8'?>
<coverage version="1">
  <file path="policy.rego">
    <lineToCover lineNumber="3" covered="true" />
    <lineToCover lineNumber="4" covered="true" />
    <lineToCover lineNumber="7" covered="false" />
    <lineToCover lineNumber="8" covered="false" />
  </file>
  <file path="policy_test.rego">
    <lineToCover lineNumber="3" covered="true" />
    <lineToCover lineNumber="4" covered="true" />
  </file>
</coverage>
