When this test fails, the error looks like this:
> FAIL: docker_api_attach_test.go:98: DockerSuite.TestPostContainersAttach
> docker_api_attach_test.go:211:
> c.Assert(actualStdout.Bytes(), checker.DeepEquals, []byte("hello\nsuccess"), check.Commentf("Attach didn't return the expected data from stdout"))
> ... obtained []uint8 = []byte{0x73, 0x75, 0x63, 0x63, 0x65, 0x73, 0x73}
> ... expected []uint8 = []byte{0x68, 0x65, 0x6c, 0x6c, 0x6f, 0xa, 0x73, 0x75, 0x63, 0x63, 0x65, 0x73, 0x73}
> ... Attach didn't return the expected data from stdout
Let's use strings for comparisons to make the output more readable.
While at it,
- get the container's stderr as well, and make sure it's empty;
- check that stdcopy.StdCopy() did not return an error, except for
the timeout which is expected;
- move/remove comments, simplify var names.
