Smoke Test

Before releasing a new version of the extension, please run the following smoke test to make sure that all features are working.

Set up

First, clone golang.org/x/example. At the time of writing (June 2020), this repository has not changed since 2017. If it has changed since, these steps may not be exactly reproducible and should be adjusted.

For now, we smoke test the extension only in GOPATH mode.

If it does not already exist:

mkdir $GOPATH/src/github.com/golang

Then,

cd $GOPATH/src/github.com/golang
git clone https://github.com/golang/example
cd example

Next, build and sideload the modified Go extension and open the example/hello directory. Open hello.go.

Test code navigation

  1. Go to definition on fmt.Println.
  2. Go to definition on stringutil.Reverse.
  3. Find all references of fmt.Println.
  4. Find all references of stringutil.Reverse.
  5. Hover over fmt.Println.
  6. Hover over stringutil.Reverse.

Test autocompletion

  1. Trigger autocompletion (Ctrl+Space) after fmt..
  2. Trigger autocompletion (Ctrl+Space) after stringutil..
  3. Enter a newline in the main function and type fmt..
  4. Enter a newline in the main function and type parser.. Expect suggestions from the unimported standard library go/parser package.
  5. Enter a newline in the main function and type fmt.. Select the fmt.Println completion and observe the outcome. Toggle the go.useCodeSnippetsOnFunctionSuggest setting to ensure that placeholders are provided.
  6. Test signature help by manually triggering it (Ctrl+Shift+Space) while completing fmt.Println.
  7. Test signature help by manually triggering it (Ctrl+Shift+Space) while completing stringutil.Reverse.

Test diagnostics

Enable go.buildOnSave, go.vetOnSave, and go.lintOnSave.

  1. Add var x int to the main function and expect a build diagnostic.

  2. Add fmt.Printf("hi", 1) and expect a vet diagnostic.

  3. Add the following function to the bottom of the file and expect a lint diagnostic.

    // Hello is hi.
func Hi() {}

You can also try toggling the "package" and "workspace" configurations for these settings.

Test formatting and import organization

  1. Hit enter 3 times in the main function and save. Expect formatting to remove all but one line.
  2. Remove the "fmt" import. Save and expect it to return.
  3. Remove the "github.com/golang/example/stringutil" import. Save and expect it to return.
  4. Confirm that the Go: Add Import command works (add "archive/tar").

Test renaming

  1. Add the following to the main function, then rename x to y.

    var x int
fmt.Println(x)

  2. Rename stringutil.Reverse. reverse.go and reverse_test.go should be dirtied.
