Principles and Guidelines to Use React Native App Testing Tools


Principles Behind Using The Testing Tools

Well, by googling the best react native apps testing tools, you may get plenty of names of the best testing tools. But, they are just mere names until you know the right method to use them. If you don’t know the accurate method to use the testing tool, then you will be like a clueless child who doesn’t know how to play with the new toy. Unless his parents taught him how to play with the new toy.

So, here we are going to be the parents and you guys will be the children whom we will teach how to play with the reacts app testing tools. Well, if you follow the basic principles and guidelines mentioned in the post, then you can easily adjust with any new testing tool.

You Should Test

We know if you are reading this post, then you are somehow interested in doing app testing. So, we will foremost recommend, you to perform app testing on your app. This will tell you whether your app has any broken code or is there any problem with the working of the app under different pressure points and many more facts.

If you are still thinking about the app testing, then we hope a word from Mark Zuckerberg will encourage you to take action. Mark talked about the role of app testing in the improvement of Facebook and also shares that they have invested a huge amount on the app testing. Kent Beck used to work at a facebook, so it makes sense that Facebook has managed to achieve such amazing results with their testing infrastructure working with the inventor of app testing.

Sometimes ‘UI’ Test Can Be Helpful

Guys unit tests are great. In fact, the majority of these suits are made up of unit tests out there. But, sometimes unit tests leaves you in a very ambiguous situation. Where you have a bunch of passed unit tests, but still, the major part of your app code is broken. This is a very common problem in a unit test. But, experts like Martin Fowler actually has a nice quote about what to do in cases where you’ve got failing high-level tests but no corresponding unit test warning you about the failure.

“I always argue that high-level tests are there as a second line of the rest defense. “

Di + Stubbing Can Be Useful With UI

With the automatic synch available in the detox, your UI can be still flakey. Even if your network speed is perfect, even then the end to end tests can be pretty slow because of some slow local networks. But, all these problems can be solved with the injection and stubbing.

Injection – Let’s take the example of water to better understand injection dependency. We all need water to survive, so if we are healthy then we can get our own water. But, if we are sick than we need the help of the IV to provide us with water. Similarly, in some cases, you need injection dependency on your codes for grabbing.

Stubbing – Assuming that you have already running DI in your app, you can replace it with the “stub”. It is fake implementation dependencies of your of your dependencies that return canned data to speed up and stabilize your tests. For example, whenever our app runs we’ll be injecting a ProductsService that can fetch products. But, however, to make the test run quicker and faster, you can use the stub.

So, yeah, people more important here is to understand the principles behind the testing tools rather than the testing tools.
