How can a specific set of test scenarios be executed?

In Go, to execute a specific set of test scenarios, you can use the testing package and run tests with the go test command filtered by the test name.

For example, if you have several tests:

func TestAdd(t *testing.T) {
    // test for the Add function
}

func TestSubtract(t *testing.T) {
    // test for the Subtract function
}

To run only the tests whose names contain Add, use:

go test -run Add

You can also create test files with different sets of tests and run them separately or use build tags to group tests.
