This is happening because of React's Strict Mode.React's Strict Mode double invokes certain function in order to identify any unwanted side-effects in your app. You can read more about it here : React Strict Mode

Now, if you go to the index.js file of your app you will see that the App is wrapped by Strict Mode. Similar is the case of index.js file in codesandbox.

You need to use await before you call the deleteArticle method as it is an async call. Function will return nothin until it finished the execution of await deleteArticleById(articleId); so you need to wait until it gets executed.

Okay, so after much tinkering & googling, I found an answer to my problem, thankfully it's relatively straightforward! 😃 - The short answer being the use of waitFor.

I made a couple of other modifications, i.e. assigned the timeout delay to a variable called timeout, but nothing major.

How to test for useEffect inside a custom hook?

Asked 2021-Jan-14 at 08:42

So I'm pretty new to testing with react. I have a custom hook that I am calling inside a component. I am using the renderHook methods from react-hook-testing-library.

I need to test if the methods inside useEffect inside the custom hook are called. I cant seem to figure this out.

In another case, I need to figure out if trackPdpGtm is not called.

Note: The hook does not return any data. This is mainly for sending analytics information.

Current Approach:

usePdpGtm.js

...

ANSWER

Answered 2021-Jan-14 at 08:42

You forget to clear the mock.calls and mock.instances properties of trackPdpGtm function mock. That's why your second test case fails. You can use jest.clearAllMocks() to clear it in afterEach hook.

E.g.

usePdpGtm.ts:

Should I compile my react hook library, or publish only the ES6 code?

Asked 2020-Jan-09 at 00:00

I have a very simple hook that I want to publish to npm, and I'm struggling to see why I should compile my hook at all. Let me first provide some context.

My hook depends only upon React.useState and React.useEffect. The purpose of this hook is to be used with my existing library: https://npmjs.com/package/simple-shared-state. As you can see, there's very little to this hook:

ANSWER

Answered 2020-Jan-09 at 00:00

You can publish ES6 code.

The current js spec is ES2020. All runtimes should support all features from this spec. Thus you need compile own code to latest standard. If user want to use your code on older runtimes(e.g. IE11) he can transpile all code in his build process.

Testing custom hook with react-hooks-testing-library throws an error

Asked 2019-May-13 at 13:14

I am trying to test a simple hook that fetches some data using axios. However the test is throwing a TypeError: "Cannot read property 'fetchCompanies' of undefined". Here's my custom hook (the full repo is here):

ANSWER

Answered 2019-May-13 at 13:14

The

TypeError: "Cannot read property 'fetchCompanies' of undefined"

is caused by the way you define the CompanyService service. In the code, you are exporting an object CompanyService with all the service methods. But in your test, you are mocking the CompanyService to return an object with the methods.

So, the mock should return a CompanyService object that is an object with all the methods:

ANSWER

Answered 2019-Mar-26 at 16:45

You have to render Parent since it contains the logic to update DateSelect. This makes for a better test because you're testing that the integration among components works.
