Decision gist · record as of 2026-08-14
Yes, if you prefer fluent assertion syntax and are comfortable with an abandoned but stable package. Surer has no dependencies, works on Python 3.6–3.11, and carries no known vulnerabilities. However, expect no active maintenance—use it only if you accept that bugs or incompatibilities with future Python versions will not be fixed by the maintainers. For new projects, consider actively maintained alternatives.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >=3.6; no system dependencies.
- Installation is frictionless with no runtime dependencies.
- However, the package is abandoned—last commit was 2023-01-08, with minimal community engagement (1 star).

{'foo': 'bar'}.should.have.key('foo')- Whether the assertion API remains stable across all supported Python versions (3.6–3.11) in practice.
- Whether the fork diverges meaningfully from the original 'sure' library beyond Python version support.
- Active maintenance status and responsiveness to bug reports or pull requests.
What it is and what it does
Surer is a fork providing fluent, chainable assertion syntax for Python tests modeled after RSpec Expectations and should.js. Instead of traditional `assert` statements, you write readable expressions like `(4).should.equal(2 + 2)` or `{'foo': 'bar'}.should.have.key('foo').which.should.equal('bar')`. It supports assertions on numbers, strings, dictionaries, and collections with a natural, English-like flow.
The package is maintained primarily to support recent Python versions (3.6, 3.7, 3.8, 3.9, 3.10, 3.11) but is no longer actively developed. It has no runtime dependencies, making installation lightweight. The last commit was 2023-01-08, and the repository shows minimal activity, so while it works for its stated purpose, you should expect no new features or rapid bug fixes.
Use it for
- Writing unit tests with more readable, fluent assertions instead of traditional assert statements.
- Testing dictionary structures and verifying nested keys and values with chainable syntax.
- Building test suites where assertion readability and developer experience are priorities.
- Migrating test code from RSpec or should.js-based projects to Python while preserving assertion style.
- Prototyping or maintaining legacy test code that already uses the 'sure' library.

More Testing packages
Pluggy provides a plugin system that lets you define hook specifications and register implementations to be called in sequence, enabling extensible Python applications without tight coupling.
Install it if you're building an extensible application or framework.
pytest is a testing framework that lets you write test functions using plain assert statements and automatically discovers and runs them, with detailed failure reporting.
virtualenv creates isolated Python environments where packages can be installed independently without affecting the system Python or other projects.
Coverage.py measures which lines of Python code are executed during test runs, reporting coverage percentages and identifying untested code paths.
Install it if you want to measure test completeness or enforce coverage thresholds in your project.
pytest-asyncio is a pytest plugin that enables writing and running async test functions using the asyncio library, allowing developers to await code directly within test cases.
Install it if you write tests for any asyncio-based code.
A pytest plugin that generates test reports in Common Test Report Format (CTRF) as JSON, compatible with pytest-xdist and pytest-playwright for distributed and browser-based testing.
Install it if you need CTRF-formatted test output for CI/CD integration or cross-tool reporting.
