Jasmine vs pytest: What are the differences?
- Feature Support: Jasmine is primarily focused on behavior-driven development (BDD) and primarily used for testing JavaScript code, while pytest is more versatile and can be used for testing Python code as well. This difference in primary focus reflects in the features each testing framework supports.
- Language Compatibility: Jasmine is mainly designed for JavaScript, whereas pytest is specifically for Python. This difference makes it easier for developers to choose between the two frameworks based on their language preferences and project requirements.
- Fixture Management: In pytest, fixture management is more flexible and versatile compared to Jasmine. Pytest allows developers to define fixtures at various scopes and reuse them efficiently throughout the test suite, providing greater control and customization options.
- Parameterized Testing: Pytest has built-in support for parameterized testing, allowing developers to run the same test with different inputs. This feature simplifies testing multiple scenarios and enhances test coverage, which is not as straightforward in Jasmine.
- Code Organization: Pytest follows a more modular approach to test organization, allowing developers to structure tests in a more intuitive and scalable manner. On the other hand, Jasmine tends to have a more rigid structure, which may not be as flexible for larger test suites or complex projects.
- Mocking Capabilities: Pytest provides more advanced mocking capabilities compared to Jasmine, enabling developers to create mock objects and simulate complex behaviors easily. This difference can be crucial for testing scenarios where external dependencies need to be mocked for isolated testing.
In Summary, Jasmine and pytest differ in terms of their feature support, language compatibility, fixture management, parameterized testing, code organization, and mocking capabilities, making them suitable for specific use cases based on developers' preferences and project requirements.
Decisions about Jasmine and pytest
Abigail Watson
We use Mocha for our FDA verification testing. It's integrated into Meteor, our upstream web application framework. We like how battle tested it is, its' syntax, its' options of reporters, and countless other features. Most everybody can agree on mocha, and that gets us half-way through our FDA verification and validation (V&V) testing strategy.

What is Jasmine?
Jasmine is a Behavior Driven Development testing framework for JavaScript. It does not rely on browsers, DOM, or any JavaScript framework. Thus it's suited for websites, Node.js projects, or anywhere that JavaScript can run.
What is pytest?
A framework makes it easy to write small tests, yet scales to support complex functional testing for applications and libraries. It is a mature full-featured Python testing tool.

What are some alternatives to Jasmine and pytest?
Mocha
Mocha is a feature-rich JavaScript test framework running on node.js and the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.
Jest
Jest provides you with multiple layers on top of Jasmine.
Karma
Karma is not a testing framework, nor an assertion library. Karma just launches a HTTP server, and generates the test runner HTML file you probably already know from your favourite testing framework. So for testing purposes you can use pretty much anything you like.
Chai
It is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework. It has several interfaces that allow the developer to choose the most comfortable. The chain-capable BDD styles provide an expressive language & readable style, while the TDD assert style provides a more classical feel.
Cypress
Cypress is a front end automated testing application created for the modern web. Cypress is built on a new architecture and runs in the same run-loop as the application being tested. As a result Cypress provides better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.
