Jest's test match does not pick my test files

Hey I can't get testMatch to pick up my test file. Here's my config:

module.exports = {
    preset: 'jest-puppeteer',
    testMatch: [
        '**/tests/**/?(*.)+spec.js'
    ]
};

My directory layout:

- Automation
    -  jest.config.js
    - tests
        - single-property
            - index.spec.js

Output:

No tests found, exiting with code 1
Run with `--passWithNoTests` to exit with code 0
In C:\Users\<user_name>\WebstormProjects\Automation
  4 files checked.
  testMatch: **/tests/**/?(*.)+spec.js - 0 matches
  testPathIgnorePatterns: \\node_modules\\ - 4 matches
  testRegex:  - 0 matches
Pattern:  - 0 matches
