As the Github Go page explains, this language was created because the developers at Google needed a language that would handle the needs of their projects. It also needed to be fast, which can be difficult when it comes to languages that come with dynamic features.. Go testing data is a library for using test data in Go tests. It can generate random, pseudo-random or pre-defined values for struct fields, variables and arrays. It is useful for benchmarking, fuzzing and test isolation.
In many cases, proper data mocking can make testing simpler and more effective than if the tests relied on real data. Here is a short list of 11 open source libraries that provide utilities for generating random test data in the Go language including gemini - Test data integrity by comparing against an Oracle running; testsql - Generate test data from SQL files; Dr Test -helps you to generate random test data that satisfy your schema definitions.
