How to query by text string which contains html tags 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?

Unit Testing in Node.js and TypeScript: A Comprehensive Guide with Jest Integration
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:
-
Express API Testing
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.
-
Alternative to AWS Mock
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.

Unit testing: What to use, and how?

Can AI help me write tests on legacy code?
🤖 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.

Unit testing with React and Cypress
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.

When to use DI?
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.
