README

Package tools provides common methods and utilities for Go(lang) based development tools that cover:

  • integration tests (primarily, ais/test/*),
  • benchmarks (under bench/),
  • aisloader.

This package and its sub-packages (listed below) should not be linked into production code. Unlike, say, cmn package (that also contains common functions) devtools is solely intended for usage with development tools.

Package devtools itself contains a spectrum of general-purpose sources and is further sub-divided into packages that group closely related functions:

Folder Intended for
archive Create, list, and read from archives
readers Provides io.Reader and related primitives based on: random source, file, scatter-gather list
tassert Testing asserts - CheckFatal, Errorf, Fatalf, and other convenient assertions
tetl Common functions used for (and by) ETL tests
tlog Uniform logging for integrations tests
