What seldom is

Seldom extends unittest with Selenium/Appium/Requests integration, offering CLI-driven test generation, HAR/Swagger conversion, parameterized test data loading, and modern HTML report generation. It runs via command-line tools rather than IDE execution.

Quickstart

Get the seldom source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/SeldomQA/seldom.git2cd seldom3# follow the project's README for install & configuration

Best use cases

Multi-channel test automation (Web/API/App)

Single framework for coordinated UI, HTTP, and mobile app testing with unified assertion and reporting layers.

Data-driven test scenarios with external datasources

Built-in support for JSON/Excel test data files and parameterized execution, reducing test code duplication.

Rapid test project scaffolding

CLI generates project structure (test_dir, test_data, reports, config) in seconds; useful for teams standardizing test organization.

Implementation considerations

Runs via CLI (seldom -p path), not IDE plugins; requires shell/script integration for test execution.
Inheritance of unittest means Python developers familiar with unittest will recognize patterns, but Seldom-specific APIs differ.
Data-driven tests load from JSON/Excel files; ensure test data is managed separately and version-controlled.
HAR/Swagger import features reduce manual test writing for API/HTTP scenarios but require valid input format.
HTML reports are generated automatically; define reports/ directory and monitor disk usage in long-running suites.

When to avoid it — and what to weigh

Require active upstream maintenance & issue response — Latest release is marked 'none (n/a)' and 13 open issues exist; no visible release cadence. Consider if your team needs timely bug fixes or feature support.
Need out-of-the-box CI/CD integration — No mention of native Jenkins, GitHub Actions, or other CI platform support; may require custom wrappers.
Enterprise-grade reporting & analytics — XTestRunner provides HTML reports but no integration with centralized test management platforms or metrics aggregation.
Require comprehensive official English documentation — README is primarily in Chinese; English examples and docs are limited. Non-Chinese teams may face onboarding friction.

License & commercial use

Apache-2.0 permits commercial use. No proprietary or open-source restrictions on using Seldom in production test automation. However, consult your legal team if integrating third-party drivers or dependencies under different licenses.

DEV.co evaluation signals

Security considerations

No explicit security audit or vulnerability disclosure policy mentioned. Seldom wraps Selenium/Appium/Requests; inherited security depends on those libraries. Avoid embedding credentials in test code or test data files; use environment variables or secrets management. No secure logging or data masking features mentioned.

Alternatives to consider

Robot Framework

Keyword-driven, language-agnostic, mature ecosystem, strong documentation. Better for non-Python teams and complex test orchestration.

Pytest + pytest-selenium/requests

More modular, larger plugin ecosystem, stronger community support. Preferred if you need flexibility and extensive integrations.

TestNG (Java) or NUnit (C#)

Better for polyglot teams or enterprises already invested in JVM/CLR. Offer mature reporting and CI/CD integration.

seldom FAQ

Can I run Seldom tests in parallel?

Not explicitly documented. Seldom inherits unittest; unittest's default runner is serial. Parallel execution requires third-party runners (e.g., pytest-xdist) or custom integration.

Does Seldom support cloud/remote testing (BrowserStack, Sauce Labs)?

Unknown. No mention in README. Custom Selenium/Appium remote URL support is likely possible via base_url config, but official integration is not documented.

What Python versions are supported?

Badge shown: 'PyPI - Python Version'. Specific versions not listed. Check PyPI page or setup.py for python_requires.

Can I integrate Seldom with my existing unittest test suite?

Yes. Seldom extends unittest.TestCase. Existing unittest tests can adopt Seldom's APIs incrementally, or run Seldom tests alongside unittest tests.
