testing

Overview ¶

Package testing is a test suit for recorders. They should provide an object that implements the Constructor interface then run:

import rt "github.com/arsham/expipe/recorder/testing"
....
type Construct struct {
    *rt.BaseConstruct
    testServer *httptest.Server
}

func (c *Construct) TestServer() *httptest.Server {
    return /* a test server */
}

func (c *Construct) Object() (recorder.DataRecorder, error) {
    return expvar.New(c.Setters()...)
}

func TestMyRecorder(t *testing.T) {
    rt.TestSuites(t, func() (rt.Constructor, func()) {
        c := &Construct{
            testServer:    getTestServer(),
            BaseConstruct: rt.NewBaseConstruct(),
        }
        return c, func() { c.testServer.Close() }
    })
}

The test suit will pick it up and does all the tests.

Important Note ¶

You need to write the edge cases if they are not covered in this section. The test suite might close and request the test server multiple times during its work. Make sure you return a brand new instance every time the TestServer method is been called. All tests are ran in isolation and they are set to be run as parallel. Make sure your code doesn't have any race conditions.
