Use a consistent testing framework across all microfrontends. When working with microfrontends, it is important to ensure consistency in the testing approach across all the microfrontends. This can be achieved by using a common testing framework that is agreed upon by all the teams working on the microfrontends. A common testing framework ensures that all the microfrontends are tested in the same way, making it easier to maintain and update them in the future.

One example of a common testing framework is Jest. Jest is a JavaScript testing framework that is widely used in the industry. It provides a simple and easy-to-use interface for writing tests and comes with a lot of built-in features that make testing easier. By using Jest as the common testing framework across all microfrontends, teams can share knowledge and best practices, making it easier to maintain and update the microfrontends.

In conclusion, using a common testing framework across all microfrontends is a best practice that ensures consistency in the testing approach. This makes it easier to maintain and update the microfrontends in the future. Jest is an example of a common testing framework that is widely used in the industry and provides a simple and easy-to-use interface for writing tests.
