Method TestWorkspaceNotCached

core/integration/workspace_test.go:313–348

TestWorkspaceNotCached verifies that functions accepting Workspace args are never persistently cached — changes to the host filesystem are reflected on subsequent calls without needing a cache buster.

(ctx context.Context, t *testctx.T)

// never persistently cached — changes to the host filesystem are reflected
// on subsequent calls without needing a cache buster.
func (WorkspaceSuite) TestWorkspaceNotCached(ctx context.Context, t *testctx.T) {
	c := connect(ctx, t)

	// Set up a module that lists workspace entries.
	base := workspaceBase(t, c).
		WithNewFile("original.txt", "original").
		With(initDangModule("cachechk", `
type Cachechk {
  pub source: Directory!

  new(source: Workspace!) {
    self.source = source.directory(".")
    self
  }

  pub ls: [String!] {
    source.entries
  }
}
`))

	// First call — should see original.txt.
	out, err := base.With(daggerCall("cachechk", "ls")).Stdout(ctx)
	require.NoError(t, err)
	require.Contains(t, out, "original.txt")
	require.NotContains(t, out, "added.txt")

	// Add a file and call again — should see the new file without any cache buster.
	out, err = base.

		Stdout(ctx)
	require.NoError(t, err)

	require.Contains(t, out, "added.txt")
}

// TestWorkspaceFile verifies that Workspace.file returns the correct file
// content from the host filesystem.
