// GOPATH mode, so they previously used relative imports. However, relative

// imports do not work in module mode. In order to make the test work in both

// run the tests as a subprocess.

// If and when we no longer support these tests in GOPATH mode, we can remove
|
|
// this shim and move the tests currently located in testdata back into the
|

// parent directory.
