How do I handle errors in async/await with Jest?
You can handle errors in async/await by using try/catch blocks in your tests. Would you like an example?
Yes, please provide an example of that.
Sure! Here's a simple example:
test('fetches data successfully', async () => {
try {
const data = await fetchData();
expect(data).toBeDefined();
} catch (error) {
fail('fetchData failed: ' + error);
}
});
What if the promise is rejected?
In that case, you can assert that the error is thrown using expect.assertions(1) and await expect(fetchData()).rejects.toThrow(). Would you like to see that?
