Golang is a lightweight, new open-source language which has several features that make automated and manual testing easier. Due to feature-rich standard library support, it provides a desirable environment for running and writing tests.
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:
3. 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.
4. 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.
5. 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.
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.
