Instructions in CONTRIBUTING.md don't seem to work out of the box

[vergilfromadyen]

What is your Scenario?

When trying to contribute to TestCafe, I'm following the instructions from CONTRIBUTING.md. Namely, I do npm install, then npx gulp build. This is enough to test a modified version of TestCafe against my project via npm link, but I was more interested in running the test suite. Using a freshly git pulled version of TestCafe.

What is the Current behavior?

1. npm install without --legacy-peer-deps fails
   

   vagrant@vagrant:~/workspace$ cat /home/vagrant/.npm/eresolve-report.txt
   # npm resolution error report
   
   2022-05-13T12:42:36.300Z
   
   While resolving: @typescript-eslint/eslint-plugin@1.13.0
   Found: @typescript-eslint/parser@3.10.1
   node_modules/@typescript-eslint/parser
     dev @typescript-eslint/parser@"^3.10.1" from the root project
   
   Could not resolve dependency:
   peer @typescript-eslint/parser@"^1.9.0" from @typescript-eslint/eslint-plugin@1.13.0
   node_modules/@typescript-eslint/eslint-plugin
     dev @typescript-eslint/eslint-plugin@"1.13.0" from the root project
   
   Conflicting peer dependency: @typescript-eslint/parser@1.13.0
   node_modules/@typescript-eslint/parser

     node_modules/@typescript-eslint/eslint-plugin
       dev @typescript-eslint/eslint-plugin@"1.13.0" from the root project
   
   Fix the upstream dependency conflict, or retry
   this command with --force, or --legacy-peer-deps
   to accept an incorrect (and potentially broken) dependency resolution.

2. There is no information about what software I need to have installed. The test suite assumes I have all the browsers that TestCafe supports, or at least Chrome and IE.

3. Running a single functional test suite, e.g. gulp test-functional-local-headless-firefox, doesn't pass out of the box.
   

What is the Expected behavior?

• There should ideally be some more instructions about what to install
• Running npm install shouldn't require the --legacy-peer-deps flag
• Functional test suites should work out of the box

What is your public website URL? (or attach your complete example)

What is your TestCafe test code?

I run this on Linux, in Vagrant, with Parallels Desktop (although VirtualBox should produce similar results). Below is my Vagrantfile:

Vagrant.configure("2") do |config|
    config.vm.provider "parallels" do |v|
      v.memory = "4096"
      v.cpus = 4
    end
    config.vm.box = "mpasternak/focal64-arm"

    config.vm.provision "shell", inline: "echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p"
    config.vm.provision "shell", inline: "curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash -"
    config.vm.provision "shell", inline: "sudo apt-get update"

    # Install node and browsers
    config.vm.provision "shell", inline: "sudo apt-get install nodejs chromium-browser firefox -y"

    # Install TestCafe dependencies as close as I could match the ones listed in the Dockerfile
    config.vm.provision "shell", inline: "sudo apt-get install libevent-dev x11-utils xvfb dbus fluxbox procps tzdata udev fonts-freefont-ttf -y"

    config.vm.synced_folder '.', '/home/vagrant/workspace'
end

The Vagrantfile, as it's currently written, should go in the root folder of TestCafe, then TestCafe will end up in ~/workspace once you vagrant up && vagrant ssh.
