Testing in Golang
                     Benefits of testing in Golang
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 Golang’s 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.
 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.
