Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
jasmine-marbles
Advanced tools
The jasmine-marbles package is a library for testing RxJS observables using marble diagrams in Jasmine. It allows developers to create and test complex asynchronous code in a more readable and maintainable way by using marble syntax to represent the behavior of observables over time.
Testing Observable Streams
This feature allows you to test the behavior of cold observables by using marble diagrams. The `cold` function creates a cold observable, and `expectObservable` is used to assert that the observable behaves as expected.
const { cold, hot, expectObservable, expectSubscriptions } = require('jasmine-marbles');
it('should test cold observable', () => {
const source = cold('--a--b--c|');
const expected = '--a--b--c|';
expectObservable(source).toBe(expected);
});
Testing Hot Observables
This feature allows you to test the behavior of hot observables. The `hot` function creates a hot observable, and `expectObservable` is used to assert that the observable behaves as expected.
const { cold, hot, expectObservable, expectSubscriptions } = require('jasmine-marbles');
it('should test hot observable', () => {
const source = hot('-a-^--b--c|');
const expected = '---b--c|';
expectObservable(source).toBe(expected);
});
Testing Subscriptions
This feature allows you to test the subscription behavior of observables. The `expectSubscriptions` function is used to assert that the observable's subscriptions match the expected subscription pattern.
const { cold, hot, expectObservable, expectSubscriptions } = require('jasmine-marbles');
it('should test subscriptions', () => {
const source = cold('--a--b--c|');
const subs = '^-------!';
expectSubscriptions(source.subscriptions).toBe(subs);
});
rxjs-marbles is another library for testing RxJS observables using marble diagrams. It provides similar functionality to jasmine-marbles but is designed to work with various testing frameworks like Jest, Mocha, and Jasmine. It offers a more flexible API and better integration with different testing environments.
jest-marbles is a library specifically designed for testing RxJS observables using marble diagrams in Jest. It provides a similar API to jasmine-marbles but is tailored for use with the Jest testing framework, offering better integration and more idiomatic Jest syntax.
