Solano CI hook scripts for CodeClimate's coverage test-reporter supporting parallel builds

README.md

This is an example for running Code Climate Test Reporter in Solano CI (ex-TDDIUM).

This example is particular for SimpleCov and Amazon's AWS but it should still be a good template for other coverage tools and cloud storage providers.

For these scripts to work you'll need to set 3 ENV vars in Solano CI:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• CC_TEST_REPORTER_ID
