| content.faq | `[{"answer":"Gatling enables teams to design complex load tests, manage testing infrastructure globally, and transform test results into actionable insights. Tests are written as code in multiple languages, integrated directly into CI/CD pipelines, and monitored through real-time dashboards. It is indexed under Testing Tools.","source":"https://gatling.io/pricing","question":"What is Gatling?","confidence":0.6},{"answer":"Gatling offers a free tier, so you can start without paying. Paid plans start at €89 per month. Prices are published openly on the vendor's own pricing page. Pricing changes often, so verify at source before relying on it.","source":"https://gatling.io/pricing","question":"Is Gatling free?","confidence":0.6},{"answer":"Gatling supports the web and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.","source":"https://gatling.io/pricing","question":"What platforms does Gatling support?","confidence":0.6},{"answer":"Yes. Gatling can be deployed cloud / SaaS, hybrid and self-hosted, so it does not have to run on the vendor's infrastructure.","source":"https://gatling.io/pricing","question":"Can Gatling be self-hosted?","confidence":0.6},{"answer":"We have confirmed 20 integrations for Gatling, including Maven, Gradle, npm, sbt, Terraform, Helm, AWS CloudFormation and AWS CDK, plus 12 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.","source":"https://gatling.io/pricing","question":"What does Gatling integrate with?","confidence":0.6},{"answer":"We have independently confirmed SOC 2 and GDPR for Gatling. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Gatling not holding them. Always confirm compliance directly before you rely on it.","source":"https://gatling.io/security","question":"What security certifications does Gatling have?","confidence":0.7}]` | `[{"answer":"pytest is a testing framework for Python that enables developers to write simple, readable tests using plain assert statements. It supports everything from basic unit testing to complex functional testing and can automatically discover test files throughout a project directory.","source":"https://docs.pytest.org/en/stable/","question":"What is pytest and what is it primarily used for?","confidence":0.95},{"answer":"pytest is designed exclusively for Python and requires Python 3.10 or later, or PyPy 3. It does not provide testing support for other programming languages.","source":"https://docs.pytest.org/en/stable/","question":"What programming languages does pytest support?","confidence":0.95},{"answer":"pytest is open source software distributed under the MIT license and is completely free to use, modify, and distribute. There is no commercial version or paid tier.","source":"https://github.com/pytest-dev/pytest","question":"What is the license and cost model for pytest?","confidence":0.95},{"answer":"Fixtures are reusable test components that set up preconditions and provide test data through a dependency injection mechanism. They eliminate boilerplate setup and teardown code, improve test clarity by using explicit function parameters, and can be easily parametrized to run tests with multiple data sets.","source":"https://docs.pytest.org/en/stable/fixture.html","question":"What are pytest fixtures and why are they important?","confidence":0.95},{"answer":"pytest uses plain Python assert statements instead of unittest's specialized assertion methods like assertEqual(), provides more detailed introspection into failing assertions, and requires less boilerplate code. Both frameworks can coexist in a project, as pytest can run unittest test suites directly.","source":"https://docs.pytest.org/en/stable/","question":"How does pytest compare to Python's built-in unittest framework?","confidence":0.93},{"answer":"Yes, pytest can execute unittest and trial test suites natively without requiring any code changes. This allows teams to adopt pytest incrementally while maintaining compatibility with existing test code.","source":"https://docs.pytest.org/en/stable/","question":"Can pytest run existing unittest test suites without modification?","confidence":0.94},{"answer":"pytest features a robust plugin system with over 1,300 external plugins available that extend its functionality for CI/CD integration, coverage reporting, parallel execution, and other specialized testing needs. This makes pytest highly customizable for different project requirements.","source":"https://docs.pytest.org/en/stable/","question":"What is pytest's plugin architecture and how extensible is it?","confidence":0.92},{"answer":"pytest follows standard Python naming conventions, automatically locating and running test files named test_*.py or *_test.py, and test functions beginning with test_. This automatic discovery eliminates the need for manual test registration or configuration in most cases.","source":"https://docs.pytest.org/en/stable/","question":"How does pytest automatically discover and run tests?","confidence":0.94}]` |
