Jest is a good and easy to go unit testing framework **Rating:** 4.0/5.0 stars **Reviewed by:** Mohini V. | Mid-Market (51-1000 emp.) **Reviewed Date:** August 27, 2023 **What do you like best about Jest?** Jest is a testing unit framework for Java - an open source software, a very handful expeirence using its application. It majorly helps in unit testing and acceptance testing the client side's web applications, just that the source code should be available in Javacript. Also, the way things has been explained in their application is commendable, makes it very clear and explainable at once. Lastly, the documentation available on their application is appreciable, highly helpful. **What do you dislike about Jest?** Jest application needs to gear up when it comes to load a bigger code, because it sometimes hang in between or takes a longer time, which makes it difficult to continue further. **What problems is Jest solving and how is that benefiting you?** Jest gives you a better expeience, because it merges with React js. It provides an easier experience in testing the frameworks. Also, the DOM testing promises fruitful testing results data. Also, if you are stuck anywhere and just by opening their applicaton or the documentation, the things are so much self explanatory that you may not need any other assistance further. ### 2. Perfect JavaScript testing framework for unit testing **Rating:** 4.5/5.0 stars **Reviewed by:** Prateek A. | Senior Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** August 25, 2023 **What do you like best about Jest?** In Jest it easy to write clear and expressive test assertions.

I like so much the "expect" function, the assertion methods and the watch mode. I used Jest with the arrange-act-assert pattern, it was great. **What do you dislike about Jest?** I had issues dealing with mocking when I worked with Jest. I am not sure if it is complicated or if I particularly struggled with this. I also dislike the default configuration for typescript. **What problems is Jest solving and how is that benefiting you?** Jest is helping developers to build tests for their code base, it allows them to test in an automated way if there is some change breaking the code or not getting the expected results. ### 11. Best Javascript Testing framework **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** July 14, 2022 **What do you like best about Jest?** Jest easy to set up with all react and react native project and comes as a default testing framework for "create-react-app". Its light and fast as its does parallellization and caching while running tests. It's one stop shop that comes with lot built in "expect" functionalities and flavours of "jasmine" makes ease writing test without imports Mocking is the heart beat of writing unit tests and jest makes it easier by providing module level mocks features and libraries. It's an interactive mode with lot of shortcuts makes easy to run specific test or test file and its allows to test only latest commit changes with git interaction watch mode The ide called Vscode has jest plugin which makes testing even more faster. **What do you dislike about Jest?** Due to its young age. It has less tooling and library support and its somewhat difficult to use across the boards of different test framework. Even though, snapshot testing it provides has lot of benefits, but that generated snapshot file size for each tests should be minimal to avoid complaiances from formatter plugin like eslint. **What problems is Jest solving and how is that benefiting you?** Jest comes with coverage in handy The coverage report is well organised and also it can handle coverage criteria restrictions and notify accordingly Shortcuts like 'press a to run all test' makes developer life easier. No need to write any configuration for including test files. Just naming file with spec.js makes jest to catch and run it. ### 12.

The feature about this tool i like the most is its ability to test multiple classes at once and even a single test can be run through it. **What do you dislike about Jest?** Overall jest is very good tool to have however there is a chance of improvement in its running speed. Its slow when it uses auto mocking feature.so that can be made better **What problems is Jest solving and how is that benefiting you?** I am using for almost 1.5 years to test my code written in js. The benefit i have realised is it helps to test the code unit wise. Every bit of code can be tested with the help of jest ### 13.
