+# Retesteth - bor
+
+These integration tests are included in the bor repo via using the git submodule  
+
+```
+[submodule "tests/testdata"]
+	path = tests/testdata
+	url = https://github.com/ethereum/tests.git
+```
+
+The version used is the last stable release, tagged as v10.4 from branch develop in ethereum/tests    
+Details on release code can be found here https://github.com/ethereum/tests/commit/a380655e5ffab1a5ea0f4d860224bdb19013f06a  
+
+To run the tests, we hava a `make` command:  
+``` 
+make test-integration
+```
+which is also integrated into the CI pipeline on GitHub  
+
+
+## Retesteth - bor on remote machine
+
+To explore and test the `retesteth` package, the following steps were executed.  
+This is only for educational purposes.  
+For future usage, there is no need to go through this section, the only thing needed is to have 'green' integration tests.  
+
+- `ssh` into a VM running bor 
+- Change configs by replacing geth with bor inside the docker container  
+```
+mkdir ~/retestethBuild
+cd ~/retestethBuild
+wget https://raw.githubusercontent.com/ethereum/retesteth/develop/dretesteth.sh
+chmod +x dretesteth.sh
+wget https://raw.githubusercontent.com/ethereum/retesteth/develop/Dockerfile
+```
+
+Modify the RUN git clone line in the Dockerfile for repo “retesteth” to change branch -b from master to develop. Do not modify repo branches for “winsvega/solidity” [LLLC opcode support] and “go-ethereum”.
+Modify the Dockerfile so that the eth client points to bor  
+e.g. : `https://github.com/ethereum/retesteth/blob/master/Dockerfile#L41`
+from `RUN git clone --depth 1 -b master https://github.com/ethereum/go-ethereum.git /geth`
+to: `RUN git clone --depth 1 -b master https://github.com/maticnetwork/bor.git /geth`
+
+- build docker image
+`sudo ./dretesteth.sh build`
+
+- clone repo
+``` 
+git clone --branch develop https://github.com/ethereum/tests.git
+```
+this step is eventually replaced by adding the git submodule directly into bor repo with   
+``` 
+git submodule add --depth 1 https://github.com/ethereum/tests.git tests/testdata
+```
+- Let's move to the restestethBuild folder
+```
+cd /home/ubuntu/retestethBuild
+```
+Now we have the tests repo here  
+```
+ls
+> Dockerfile  dretesteth.sh  tests
+```
+- Run test example    
+```
+./dretesteth.sh -t GeneralStateTests/stExample --  --testpath /home/ubuntu/retestethBuild/tests --datadir /tests/config
+```
+This will create the config files for the different clients in ~/tests/config
+Eventually. these config needs to be adapted according to the following doc  
+https://ethereum-tests.readthedocs.io/en/latest/retesteth-tutorial.html
+Specifically:  
+``` 
+f you look inside ~/tests/config, you’ll see a directory for each configured client. Typically this directory has these files:
+
+config, which contains the configuration for the client:
+The communication protocol to use with the client (typically TCP)
+The address(es) to use with that protocol
+The forks the client supports
+The exceptions the client can throw, and how retesteth should interpret them. This is particularly important when testing the client’s behavior when given invalid blocks.
+start.sh, which starts the client inside the docker image
+stop.sh, which stops the client instance(s)
+genesis, a directory which includes the genesis blocks for various forks the client supports. If this directory does not exist for a client, it uses the genesis blocks for the default client.
+```
+
+We replaced geth inside docker by using https://ethereum-tests.readthedocs.io/en/latest/retesteth-tutorial.html#replace-geth-inside-the-docker  
+Theoretically, we would not need any additional config change  
+
+- Run test suites    
+``` 
+./dretesteth.sh -t <TestSuiteName> --  --testpath /home/ubuntu/retestethBuild/tests --datadir /tests/config
+```
+Where `TestSuiteName` is one of the maintained test suites, reported here https://github.com/ethereum/tests  
+```
+BasicTests
+BlockchainTests
+GeneralStateTests
+TransactionTests
+RLPTest
+src
+```
+
+If you want to run retestheth against a bor client on localhost:8545 (using 8 threads), instead of isolating it into a docker image, run  
+`sudo ./dretesteth.sh -t GeneralStateTests -- --testpath ~/tests --datadir /tests/config --clients t8ntool --nodes 127.0.0.1:8545 -j 8`
