I think it's good to test that the fixture is correct. My point related more to the `context` and `it` descriptions. The `it` description doesn't really follow the `context` description, i.e. I would have expected something more like:

```
context "before the integration tests run" do
  it "ensures we have a valid vApp fixture" do
     [...]
  end
end
```

This would also make the test description more readable on the CLI.
