+In order to run the tests **on NodeJS**, do as follows:
+
+```
+npm run tests-unit
+npm run tests-devnet
+npm run tests-testnet

+#### In the browser
+
+Make sure you have the package `http-server` installed globally.
 
 ```
-npm run test
-npm run test-local-testnet
-npm run test-testnet
-npm run test-mainnet
+npm install --global http-server
 ```
 
-For the `local-testnet` tests, make sure you have a Testnet running locally. A local Testnet can be started from the Elrond IDE or from [erdpy](https://docs.elrond.com/developers/setup-a-local-testnet-erdpy).
