- They are being performed on matched elements.Expect verifies if a certain value is as expected to be.As we can see detox covers a lot of possible user interactions that can be automated.Make our tests moreÂ readableTo be honest, we can do much better.First letâs get rid of the duplication for matchers…
- Automate the process and land on the moonÂ đOnce we reached a certain amount of tests, we thought it could be nice to automate the process and think in terms of âcontinuous testingâ.
- Thatâs why we decided to run the end-to-end test on our build server.Every new pull request that comes in, triggers unit tests with Jest on CircleCI and now also our end-to-end tests on Bitrise (our build server).
- This is mostly due to the Detox build scripts.AlternativesWe also considered others libraries such as:Appium which is a cross platform test library where tests can be written in many languages (node, ruby, java,Â âŚ ).
- Hence, our choice of using Detox.ConclusionIn this article we saw how to handle Detox and its API, how to automate everything with Bitrise (or any CI that can runs an IOS Simulator).
When we started writing our React-Native app at Home, testing was something we took seriously from day one. While it was easy to setup a proper unit-tests workflow with Jest and Typescript, we figure…

- Testing can help identify bugs introduced during the development phase of the app and addressing these bugs before release means that your users will always get to use a reliable product.What kind of tests can weÂ use?Unit tests are used to test small modular pieces of code (aka units) independently.Integration tests…
- One of my favorite things about Jest is a feature called Snapshot testing.Snapshot tests are a very useful tool whenever you want to make sure the UI for a component or the object from an redux action or reducer does not change unexpectedly.Hereâs a good explanation of what a snapshot…

- Hereâs how we handle them in Detox:LoginHereâs a simple example of what a detox test for logging into the app might look like:DemoAnd finally, hereâs a part of our E2E test suite in action.
- Also, automating the tests on Bitrise CI has helped us streamline our release pipeline by preceding every release with the tests workflow.Hopefully, this post details how easy it is to test a React Native app and automate the testing process as well.
At Pillow, we release an update to our Pillow Pro app (iOS & Android) every 2 weeks or so. Most releases are over-the-air (OTA) updates that are done using CodePush, and are fully automated with…
