Jest vs TeamCity: What are the differences?

Introduction: This markdown code will outline the key differences between Jest and TeamCity.

Testing Framework vs. CI/CD Tool: Jest is primarily a testing framework used for unit testing JavaScript code, offering features like test runners, assertion libraries, and mocks. On the other hand, TeamCity is a continuous integration and delivery tool that focuses on automating the build, test, and deployment processes of software projects.
Scope of Functionality: Jest is specifically designed for writing and running tests for JavaScript code, making it ideal for frontend and backend developers working on JavaScript projects. In contrast, TeamCity offers a broader range of functions beyond testing, including build automation, version control system integration, and deployment management, catering to the needs of DevOps teams.
User Interface: Jest provides a user-friendly interface for writing and executing tests, with colorful and informative output to quickly identify test results. While TeamCity also offers a user interface for monitoring and managing CI/CD pipelines, it focuses more on displaying build and deployment statuses, logs, and statistics rather than test results.
Community Support: Jest has a large and active community of developers contributing to its development, providing a wealth of resources, plugins, and tutorials for users. TeamCity, as a proprietary tool developed by JetBrains, offers professional support and documentation but may have a smaller community compared to Jest.
Integration Capabilities: Jest integrates seamlessly with popular tools and libraries in the JavaScript ecosystem, such as npm, Babel, and ESLint, enhancing its functionality and compatibility with modern JavaScript projects. TeamCity, on the other hand, supports integration with various version control systems like Git and Mercurial, as well as popular build tools and artifact repositories for streamlined CI/CD workflows.
Pricing Model: Jest is an open-source testing framework released under the MIT license, making it free to use and redistribute for commercial and non-commercial purposes. In contrast, TeamCity offers a proprietary licensing model with different pricing tiers based on the number of build agents and additional features required, making it a commercial product with associated costs for organizations.

In Summary, Jest and TeamCity differ in their focus on testing vs. CI/CD, functionality scope, user interface, community support, integration capabilities, and pricing model.

Advice on Jest, TeamCity

Cypress

Jest

As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.

Postman will be used to do integration testing with the backend API we create. It offers a clean interface to create many requests, and you can even organize these requests into collections. It helps to test the backend API first to make sure it's working before using it in the front-end. Jest can also be used for testing and is already embedded into React. Not only does it offer unit testing support in javascript, it can also do snapshot testing for the front-end to make sure components are rendering correctly. Enzyme is complementary to Jest and offers more functions such as shallow rendering. UnitTest will be used for Python testing as it is simple, has a lot of functionality and already built in with python. Sentry will be used for keeping track of errors as it is also easily integratable with Heroku because they offer it as an add-on. LogDNA will be used for tracking logs which are not errors and is also a Heroku add-on. Its good to have a separate service to record logs, monitor, track and even fix errors in real-time so our application can run more smoothly.

Detailed Comparison

Jest	TeamCity
Jest provides you with multiple layers on top of Jasmine.	TeamCity is a user-friendly continuous integration (CI) server for professional developers, build engineers, and DevOps. It is trivial to setup and absolutely free for small teams and open source projects.
Familiar Approach: Built on top of the Jasmine test framework, using familiar expect(value).toBe(other) assertions;Mock by Default: Automatically mocks CommonJS modules returned by require(), making most existing code testable;Short Feedback Loop: DOM APIs are mocked and tests run in parallel via a small node.js command line utility	Automate code analyzing, compiling, and testing processes, with having instant feedback on build progress, problems, and test failures, all in a simple, intuitive web-interface; Simplified setup: create projects from just a VCS repository URL;Run multiple builds and tests under different configurations and platforms simultaneously; Make sure your team sustains an uninterrupted workflow with the help of Pretested commits and Personal builds; Have build history insight with customizable statistics on build duration, success rate, code quality, and custom metrics; Enable cost-effective on-demand build infrastructure scaling thanks to tight integration with Amazon EC2; Easily extend TeamCity functionality and add new integrations using Java API; Great visual project representation. Track any changes made by any user in the system, filter projects and choose style of visual change status representation;
