How Can I Selectively Skip Packages or Tests in Go?

Skipping Packages in Go Testing

Go testing offers the flexibility to select specific packages for testing, bypassing those you wish to exclude.

Skipping Specific Directory

To skip a particular directory from testing, you can specify the packages you want to test individually. For example, given the directory structure:

mypackage
mypackage/net
mypackage/other
mypackage/scripts

To test only mypackage, mypackage/other, and mypackage/net, use the following command:

go test import/path/to/mypackage import/path/to/mypackage/other import/path/to/mypackage/net

Using Shell Substitution

You can also use shell substitution for this purpose:

go test import/path/to/mypackage{,/other,/net}

Using go list

The go list command can be employed to generate a list of packages to test, excluding undesired directories:

go test `go list ./... | grep -v directoriesToSkip`

Skipping Tests Based on Conditions

If you wish to skip tests based on certain conditions, you can utilize the testing.Short() function within your tests. By calling t.Skip() appropriately, you can ensure that these tests are omitted.

To run tests selectively based on the presence of the testing.Short() flag, use one of the following commands:

go test -short import/path/to/mypackage/...

or

go test -short ./...

This method allows you to skip costly or time-consuming tests as needed.
