Add callbacks to be run after and before each test

[esdrasbeleza]

I need to store and analyse data about my tests: suite names, test names, and test duration. Since I can't do that directly using go test, I modified testify for that.

The following sample suite

type TestifySuite struct {
    suite.Suite

    debugFile *os.File
}

func (t *TestifySuite) SetupSuite() {
    t.debugFile, _ = os.Create("debug.log")
}

func (t *TestifySuite) TearDownSuite() {
    t.debugFile.Close()
}

func (t *TestifySuite) BeforeTest(suiteName, testName string, when time.Time) {
    data := fmt.Sprintf("%s - %s - Started at %s\n", suiteName, testName, when.Format(time.RFC1123))
    t.debugFile.WriteString(data)
}

func (t *TestifySuite) AfterTest(suiteName, testName string, when time.Time) {
    data := fmt.Sprintf("%s - %s - Finished at %s, passed: %t\n", suiteName, testName, when.Format(time.RFC1123), !t.T().Failed())
    t.debugFile.WriteString(data)
}

func (t *TestifySuite) Test_Something_OK() {
    assert.Equal(t.T(), 2, 1+1)
}

func (t *TestifySuite) Test_Something_Fail() {
    assert.Equal(t.T(), 2, 3)
}

func Test(t *testing.T) {
    testify := &TestifySuite{}
    suite.Run(t, testify)
}

will produce this log file:

TestifySuite - Test_Something_Fail - Started at Sun, 26 Jun 2016 18:14:33 BRT
TestifySuite - Test_Something_Fail - Finished at Sun, 26 Jun 2016 18:14:33 BRT, passed: false
TestifySuite - Test_Something_OK - Started at Sun, 26 Jun 2016 18:14:33 BRT
TestifySuite - Test_Something_OK - Finished at Sun, 26 Jun 2016 18:14:33 BRT, passed: true

We can use these functions to store test results in database, generate files for continuous integration etc.

Hi @esdrasbeleza, sorry it took so long to reply. I've been very busy.

I would rather do this without sending the times. You can call time.Now() within the callback.

@ernesto-jimenez, I removed the when from callback signatures.

@esdrasbeleza 👍 thanks!
