Ah I figured some of it out. For others that may see this,

<https://github.com/pulumi/pulumi/blob/master/pkg/testing/integration/program.go>

package runs the magic here. It does a

yarn link

of the local code into a test program, the crucial step I was missing however was to

make build

the typescript into the

bin/*.js

that is actually ran. I am still having issues but seem closer

Next issue seemed to be in this part of my test:

opts := base.With(integration.ProgramTestOptions{
		Dependencies: []string{
			"@pulumi/docker",
		},
		Dir: path.Join(cwd, "hadolint"),
	})

Since I am developing on my fork, I needed to change it to

@timmyers/pulumi-docker

.
