I have the following react-native-form:
ANSWER
Answered 2020-Dec-04 at 18:24I think the reason why it returns undefined for you is that you are trying to test asynchronous behaviour in a sync way. I would suggest using Promises in your onSubmit method to wait for the firebase auth call to finish.
Something like this could work
QUESTION
I am new to the world of testing.
I have react-native-formly npm library written entirely in javascript but have a component or two which are dependent on native libraries like react-native-image-picker.
Recently, I updated all my dependencies thinking it won't cause any breaking changes but it turned out it actually did.
My primary goal here is to write test cases for the component which require native implementation (test case as simple as app doesn't crash on initialising my component).
...ANSWER
Answered 2020-May-11 at 01:43Covering Testing Native components:
As React Native components are written in js and can be tested with jest (as your choice of testing suite), we can still test "native" components since those components are wrapped with the js component.
Note: All native components are wrapped native-bridge docs such that JS -> communicates with native component.
Therefore, you can still test native components as you would expect from a TDD level.
However, as jest or other suites will be unable to render correctly say, the camera module within the js runtime, you will at times have to mock those functions.
This can be done with jest.fn()
A good reference for testing the react-native-camera.js can be found in the react-native-community docs
e.g.
QUESTION
I have never written test cases so I am totally not sure on how to achieve this (and have never worked with travis as well).
I have react-native-formly npm library written entirely in javascript.
Every time dependent bot creates a request, before merging, I want it run test cases and only merge if the app loads and does not crashes. I have seen other open source repo have travis.yml which they used to achieve this but it is still vague to me on how I could achieve it.
Can someone guide me on how to achieve this? what kind of test cases/library I should use. I know there are libraries like jest for snapshot testing but I don't care much if the UI renders differently.
...ANSWER
Answered 2020-May-07 at 07:42You need some kind of end-to-end test if you want to run the app, and ensure it doesn't crash.
Have a look at Cypress (http://cypress.io) or webdriverio (http://webdriver.io)
Cypress has docs on setting up with CI/CD https://docs.cypress.io/guides/guides/continuous-integration.html#Setting-up-CI
Edit... Sorry I missed the react-native part. The above would work for web apps, have a look at something like Detox for React Native (https://github.com/wix/Detox)

QUESTION
I am new to react-native. I am trying to validate a text field on click of Submit button. But I always get the error -
TypeError: undefined is not an object (evaluating 'props.deviceLocale') on my emulator.
(I am using an Android emulator).
However I am nowhere using 'deviceLocale' in my code. I am not aware if it is required for anything I have in my code.
This is my code:
...ANSWER
Answered 2019-Mar-26 at 14:54You are getting the error even before loading of the component then, do bind your _onPressButton correctly, then atleast your component will get mounted properly, then then your upcoming errors will follow like the use of this.validate is somewhat ambiguous to me as I cannot see validate function in the component.
To bind your _onPressed, declare it like below:
QUESTION
I feel crazy asking this question here, but I can't find any good tutorials for how to submit a form and capture the data for RN. Everything I do find is someone pushing a library "just npm install react-native-form-genie-magic-box and call it in your project"...

...ANSWER
Answered 2019-Feb-16 at 23:18Your code seems correct.
Only possible issue may be setTimeout that runs this.setState in different scope as I see in error screen which shows backtrace with timers.
I recommend You to use async/await and handle all throwables using try...catch construction.
For timers You can use such method:
