I'm new to app testing and have started delving into this topic since yesterday. I wanted to write tests for my React Native app and tried to install React Native Testing Library with this command:

npm install --save-dev @testing-library/react-native @testing-library/jest-native

Then I ran into the following problem:

I tried to find a solution to this problem in Google, but I did not succeed. As far as I understand, the problem lies in the dependencies? Please tell me what can I do in this case?

P.S. I tried to create a completely clean project with expo init, tried to install the library but got exactly the same error

Hit the same issue and didn't want to update everything at the moment so I solved the issue by running a suggestion on the npm error output:

npm install --save-dev @testing-library/react-native --legacy-peer-deps

It worked for me

it looks like you are running into a conflict with your react version dependencies. Please check the named modules for required packages they depend on. Please have a look with: npm outdated and then maybe try to update your settings via npm update

also take a look here if you want: updating npm dependencies

you need to update react version after updating just install the latest version of testing-library
