How to Implement Placeholder Tests in Go: Skip or Dummy Functions?

Writing Placeholder Tests in Go

Many testing frameworks, such as Mocha.js, support the concept of pending tests, which mark a test as incomplete or not yet implemented. This can be useful for tracking progress on a project or indicating that certain functionality has not yet been tested.

In Go, there is no native support for pending tests. However, there are several ways to achieve similar functionality. One option is to use the testing.T.Skip method, as suggested in the solution provided:

<code class="go">import "testing"

func TestTimeConsuming(t *testing.T) {
    if testing.Short() {
        t.Skip("skipping test in short mode.")
    }

    // Test implementation...
}</code>

When the above test is run using the go test -v -short command, the skip message will be printed:

=== RUN   TestTimeConsuming
--- SKIP   TestTimeConsuming (0.00s)
        TestTimeConsuming.go:9: skipping test in short mode.

This method allows you to mark tests as pending with a custom message, which can be useful for indicating the reason for the skip.

Another approach is to create a dummy test function that simply returns:

<code class="go">func TestPlaceholder(t *testing.T) {}</code>

This test will pass if it is called, but it provides no actual functionality. Its purpose is solely to serve as a placeholder for a future test implementation.

Which method you choose depends on your specific needs and preferences. Both approaches provide a way to mark tests as incomplete or pending in Go.
