+# How to test
+
+This document describes how to set up and run the tests for the Committee Service.
+The point is to avoid "it worked on my machine" scenarios.

+## Prerequisites
+* CentOS 7 - (AWS us-east-1 ami-02eac2c0129f6376b)
+
+The below commands will install the listed dependencies on CentOS 7. If you use Ubuntu, or
+another different release, take the list and find the commands to get the dependencies.
+### Build prerequisites
+* cmake3 (from EPEL) (CentOS defaults to v2)
+* gcc, c++ compiler, git
+
+Commands that build/install these: (run as root)
+```bash
+yum install -y epel-release
+yum install -y git cmake3 gcc gcc-c++
+alternatives --install /usr/local/bin/cmake cmake /usr/bin/cmake3 20 \
+--slave /usr/local/bin/ctest ctest /usr/bin/ctest3 \
+--slave /usr/local/bin/cpack cpack /usr/bin/cpack3 \
+--slave /usr/local/bin/ccmake ccmake /usr/bin/ccmake3 \
+--family cmake
+```
+(Note that this will allow regular users to run the `cmake` command but not the root user.)
+
+### Python prerequisites
+* python 3.7 (CentOS defaults to 2.7 and 3.6)
+
+Commands that build/install these: (run as root)
+```bash
+yum install -y openssl-devel bzip2-devel libffi-devel wget
+wget -O /usr/src/Python-3.7.6.tgz https://www.python.org/ftp/python/3.7.6/Python-3.7.6.tgz
+tar xzf /usr/src/Python-3.7.6.tgz -C /usr/src
+cd /usr/src/Python-3.7.6
+./configure --enable-optimizations
+make altinstall
+alternatives --install /usr/local/bin/python python /usr/local/bin/python3.7m 5 --family python
+alternatives --set python /usr/local/bin/python3.7m
+```
+(Note: as before, this will make Python 3.7.6 default for regular users. Not for root.)
+
+### Docker prerequisites
+* Docker (make it available for regular users - the pre v19.03 way)
+
+Commands that build/install these: (run as root)
+```bash
+yum install -y docker
+groupadd docker
+gpasswd -a centos docker
+systemctl enable docker
+systemctl start docker
+```
+Make sure you exit from the user session and re-login so you get access to docker as the `centos` user.
+
+### Source code prerequisites
+* Access to git (probably an SSH key set up)
+* Get the source code
+
+Commands that build/install these: (run as a regular user, like `centos`)
+```bash
+git clone git@github.com:starkware-libs/starkex-resources
+cd starkex-resources
+```
+All future commands will be run from this directory unless otherwise specified.
+
+### Testing dependencies
+If you want to run `./presubmit.sh` that also does integration testing and reporting on errors,
+you need to install additional dependencies.
+
+* Docker-compose for the container setup
+* gmp.h header file for one of the pip3 packages
+* Temporarily disable SELinux (for this session only)
+* Specific version of `marshmallow-dataclass` Python package (7.1.0)
+* New version of NPM (CentOS defaults to a very old version)
+
+Commands that build/install these: (run as root)
+```bash
+yum install -y gmp-devel docker-compose
+pip3 install tox marshmallow-dataclass==7.1.0
+setenforce 0
+curl -sL https://rpm.nodesource.com/setup_13.x | sudo bash -
+yum install -y nodejs
+```
+
+## Build
+After installing the above dependencies, as a regular user, build with the command:
+```bash
+./build.sh
+```
+Optionally, add a 'flavor' input parameter to build into a different directory. (Default flavor is 'Release'.)
+
+## Build and test
+After installing the above dependencies (including dependencies for testing), as a regular user (with docker access),
+build and test with the command:
+```bash
+./presubmit.sh
+```
+Optionally, add a 'flavor' input parameter to use with a different directory. (Default flavor is 'Release'.)
