Go Training 1: Getting Go

• Introduction to go
• Installing go
  • hello world
  • go run
    • go run main.go
    • runs the code without creating a binary
    • good for testing programs iteratively
  • go build
    • creates a binary
    • good for distributing programs
• using go modules
  • go mod init your.domain/path
  • this is all we will do for now with go modules
• creating another go file: math.go
  • adding numbers
  • divide by zero

Go Training 3

• Testing
  • Test math.go
• HTTP Testing
  • Testing the real production server
  • Creating a fake server
  • sending a HTTP request to that server via the make request function we made earlier
  • intentionally creating bad state
• Adding contexts
  • Add the arguments
  • Add it to the HTTP request
  • Create test case for fake server timing out a context
