Golang Testing

1
Benefits of testing in Golang
2
Introduction

• Go is a modern open-source language that has
  several features which make manual as well as
  automated testing easier.
• Go Test tool conducts writing tests at
  development time.
• Golang provides code coverage analysis,
  displaying exact lines exercised by tests.
• Following are some of the advantageous features
  Golang brings to testing environment

Logrus

• Logrus is a feature-rich structured logger for
  Golang. We can write logs asynchronously to avoid
  extra overhead on the system.
• Benefits
•  Due to asynchronous logging important resources
  can be saved for other priority tasks.
•  Service Hooks such as Airbrake help in quick bug
  fixing and superior test code quality while Redis
  features in-memory data set.
•  Efficiently track and write logs that result in
  neat and well-written code.

Golang Benchcmp

• The benchcmp command displays performance changes
  between benchmarks. Benchcmp parses the output of
  two 'go test' benchmark runs, correlates the
  results per benchmark, and displays the deltas.
• By setting benchmarks we can easily compare
  system calls by understanding which piece/version
  of code performs better.
• Benefits
• Implement superior quality code which is free of
  any performance bottlenecks.

Uber Go-Torch

• Uber Go-Torch is a tool for stochastically
  profiling Go programs. It collects stack traces
  from Golangs built-in pprof library and
  synthesizes this information into a flame graph.
  The flame graph generates data sets about Time
  consumption, Memory Consumption, CPU Usage and
  more.
• Benefits
• With so many inputs at their disposal, Uber
  Go-Torch helps developers to understand and
  optimize the code to improve system performance
  to the function level.
• The resulting code is optimized for speed, CPU
  usage, memory usage, performance and time.

6
Golang Pprof

• Golang Pprof is Golangs built-in Library. It
  continually generates data. By utilizing the
  Pprof tool we are able to perform CPU profiling
  of the system. It helps us analyze the CPU dump
  and then generate reports on performance in the
  CPU by generating a flame graph.
• Benefits
• When used in collaboration with Uber Go-Torch,
  Golang Pprof helps develop code that performs at
  an optimized level.
