react-testing-library VS Sinon.JS

I'm currently testing an input using Jest & react-testing-library. I'm trying to test whether the onChange function fires whenever my input's field changes. Here's an example of my code:

I am trying to test the onChange event of a Select component using react-testing-library.

Reactjs Current Working Solution Using this html: Name: Bob (special guest) I can use the React Testing Library getByTestId method to find the textContent: expect(getByTestId('foo').textContent).toEqual('Name: Bob (special guest)') Is there a better way? I would like to simply use this html: Name: Bob (special guest) And use React Testing Library's getByText method like this: expect(getByText('Name: Bob (special guest)')).toBeTruthy() But this does not work. So, the question… Is there a simpler way to use React Testing Library to find strings of text content with the tags striped out?

I am new to react-testing-library / jest and attempting to write a test to see if the navigation of routes (using react-router-dom) is performed correctly. So far I have been following the README and this tutorial on how to use.

I'm using react-testing-libarary to test my react application. For some reason, I need to be able to find the element by id and not data-testid. There is no way to achieve this in the documentation.

If you are using a mocking library, such as sinon, jest-mock, or ts-mockito, make sure that it is compatible with Jest. You may need to install additional packages or configure them in your configuration file. For example, to use sinon with Jest, you can install the sinon-jest package and add the following to your configuration file:

Mocha is a test runner, Chai is an assertion library, Sinon is a mocking library, this normally the combination you would need to use if you choose mocha, but there are others.

Instead, use pure functions + dependency inject your stubs (e.g. parameter to function). Also note, no need for Sinon or some other test double library. JavaScript is so good nowadays to easily make objects/classes/functions or any combination thereof on the fly that are terse.

I've had some good experiences with Ava + Sinon. I've personally disliked Jest because it seemed to do some weird trickery in the background that prevented me from using ES modules.

🤖 You can use the Mocha testing framework with the Chai assertion library to write tests for your Express controller. You can also use the Sinon library to mock the database calls. This will allow you to test the controller without actually making a call to the database. You can also use the SuperTest library to make HTTP requests to the controller and test the response.

You can use sinon js to create a mock version of your http library (axios) that responds with the data you’re expecting.

Assertions are the checkpoints of our test block that confirm if an automated test has passed or failed. Cypress bundles the Chai, jQuery, and Sinon.JS libraries for assertions. They check the desired, expected application in which the test is running. A complete listing of assertions can be found in the documentation here.

ES module is basically a "class" that you inject dependencies into through imports. And for tests you just use something like sinon to swap module dependencies for mocks.

You can use a tool like sinon to pass in your own function instead of the real moment library. From there you can write tests that ensure moment was invoked appropriately.

Let's configure tests with mocha, chai and sinon on Typescript in a few steps.
