Tests Checker

To install this bot to your Open Sourced project:



You can configure bot by adding .github/tests_checker.yml file to the repository and override any of the settings listed below.

Default values are:

comment: 'Could you please add tests to make sure this change works as expected?',
fileExtensions: ['.php', '.ts', '.js', '.c', '.cs', '.cpp', '.rb', '.java']
testDir: 'tests'


  • comment - a text that bot will post when it won't find tests in the PR
  • fileExtensions - extensions of the files that should be treated as a source code. Bot will do nothing if you just updating README.md because usually no tests are required to cover such change.
  • testDir - folder, where tests are located. Make sure to set it correctly, otherwise bot will not be able to understand whether the test file was added or not.

If you want to change only directory where the tests are placed, just add .github/tests_checker.yml:

testDir: app-tests

If you don't want to change anything, you can skip creating this file.


This is needed if you want to deploy this bot to your server or want to contribute to it. Please note, that tests-checker is ready to use. You just need to install Github Application as mentioned in above.

# Install dependencies

npm run build

# for development
