Go Recipes for Developers

By: Burak Serdar

Overview of this book

With its simple syntax and sensible conventions, Go has emerged as the language of choice for developers in network programming, web services, data processing, and other settings. This practical guide helps engineers leverage Go through up-to-date recipes that solve common problems in day-to-day programming. Drawing from three decades of distributed systems engineering and technical leadership at companies like Red Hat, Burak Serdar brings battle-tested expertise in building robust, scalable applications. He starts by covering basics of code structure, describing different approaches to organizing packages for different types of projects. You’ll discover practical solutions to engineering challenges in network programming, dealing with processes, databases, data processing pipelines, and testing. Each chapter provides working solutions and production-ready code snippets that you can seamlessly incorporate into your programs while working in sequential and concurrent settings. The solutions leverage the more recent additions to the Go language, such as generics and structured logging. Most of the examples are developed using the Go standard library without any third-party packages. By the end of this book, you’ll have worked through a collection of proven recipes that will equip you accelerate your Go development journey.

Logging in tests

Often additional logging functionality is useful for tests to show the state of critical variables, especially if a failure occurs. By default, the Go test executor does not print any logging information if tests pass, but if a test fails, the logging information is also included in the output.

How to do it...

  1. Use testing.T.Log and testing.T.Logf functions to record log messages in tests:
    func TestSortTimeAscending(t *testing.T) {
      ...
      t.Logf("Input: %v",input)
      output:=SortTimes(input,true)
      t.Logf("Output: %v", output)
  2. Run the tests. If the test passes, no log information will be printed. If the test fails, logs will be printed.

    To run the tests with logs, use the -v flag:

    $ go test -v
    === RUN   TestSortTimesAscending
        sort_test.go:17: Input: [2023-02-01 12:08:37 -0700 MST 2021-05-06 09:48:11 -0600 MDT 2022-11-13 17:13:54 -0700 MST 2022-06-23 22:29:28...
