Hands-On Software Engineering with Golang

Setting up a test suite for the graph implementation

Before we conclude our tour of the in-memory graph implementation, we need to spend some time authoring a test suite that will execute the shared verification suite against the store implementation we just created. This can be achieved with only a handful of lines, as follows:

var _ = gc.Suite(new(InMemoryGraphTestSuite))

type InMemoryGraphTestSuite struct {
    graphtest.SuiteBase
}

func (s *InMemoryGraphTestSuite) SetUpTest(c *gc.C) {
    s.SetGraph(NewInMemoryGraph())
}

// Register our test-suite with go test.
func Test(t *testing.T) { gc.TestingT(t) }

Since we are working with a pure, in-memory implementation, we can cheat and recreate the graph before running each test by providing a SetUpTest ...
