Running unit tests

Use the Go build system tools to run unit tests.

How to do it...

1. To run all unit tests in the current package, input the following:

   go test
   PASS
   ok  github.com/PacktPublishing/Go-Recipes-for-Developers/src/chp17/sorting/sort    0.001s

2. To run all unit tests in a package, input the following:

   go test <packageName>

   Or, input the following:

   go test ./<folder>

   Here is an example:

   go test github.com/PacktPublishing/Go-Recipes-for-Developers/src/chp17/sorting/sort

   Or, you can input the following:

   go test ./sorting

3. To run all unit tests in all packages of a module recursively, input the following:

   go test ./...

   Do this from the root directory of the module.

4. To run a single test in the current package, input the following:

   go test -run TestSortTimesAscending

   This form treats the test name after the -run flag as a regular expression and runs all tests that contain that string. For instance, go test -run Sort will run all tests...
