Were developer tests stored somewhere? Were the results exported somewhere?

In most projects, developers' tests are stored in the version control system along with the main code, usually in a separate directory, such as tests/. Test results are often exported to CI/CD systems like Jenkins, GitLab CI, or GitHub Actions, where they are displayed as reports with detailed information about passed and failed tests. Specialized tools for collecting code coverage metrics and analyzing results, such as Allure or ReportPortal, may also be used, allowing for convenient viewing of test history and identification of problematic areas.
