There are external packages that can be integrated with the stock testing framework.
One of them I wrote long ago, gocheck, was intended to sort that kind of use case.
With it, the test case looks like this, for example:
func (s *Suite) TestFoo(c *gocheck.C) {
// If this succeeds the world is doomed.
c.Assert("line 1\nline 2", gocheck.Equals, "line 3")
}
You'd run that as usual, with go test
, and the failure in that check would be reported as:
----------------------------------------------------------------------
FAIL: foo_test.go:34: Suite.TestFoo
all_test.go:34:
// If this succeeds the world is doomed.
c.Assert("line 1\nline 2", gocheck.Equals, "line 3")
... obtained string = "" +
... "line 1\n" +
... "line 2"
... expected string = "line 3"
Note how the comment right above the code was included in the reported failure.
There are also a number of other usual features, such as suite and test-specific set up and tear down routines, and so on. Please check out the web page for more details.
It's well maintained as I and other people use it in a number of active projects, so feel free to join on board, or follow up and check out the other similar projects that suit your taste more appropriately.
For examples of gocheck use, please have a look at packages such as mgo, goyaml, goamz, pipe, vclock, juju (massive code base), lpad, gozk, goetveld, tomb, etc. Also gocheck, manages to test itself. It was quite fun to bootstrap that.
