Testing and Debugging

Unit Tests

• Purpose: The unit tests verify the functionality of individual components of the project.

• Location: The unit tests are located in the tests directory. For example, tests for the docker command can be found in tests/docker_test.go.

• Execution:

  • To run all unit tests: go test ./...
  • To run tests for a specific package: go test ./tests/docker
  • To run tests for a specific file: go test ./tests/docker/docker_test.go

• Example:

  // docker_test.go
            package docker
            
            import (
                "testing"
            )
            
            func TestDockerRun(t *testing.T) {
                // ... test code ...
            }
            

Debugging

• Tools:

  • Go Debugger: The Go debugger (dlv) provides a powerful way to inspect the execution of your code.
  • Print Statements: Adding fmt.Println statements to your code can be a simple way to debug.

• Example:

  # Start a debugging session
            dlv debug ./main.go
            
            # Set a breakpoint at a specific line
            break main.go:15
            
            # Continue execution
            continue
            
            # Inspect variables
            print variable
            

• Debugging in Docker:

  • Attach to a running container: docker exec -it container-id bash
  • Use gdb or other debuggers within the container.
