testing: Assert(...error)

[lukescott]

I have some helper functions that do certain tests and return helpful output as en
error. To preserve helpful line numbers I have to do this every time:

if e := test.Equals(obtained, expected); e != nil {
    t.Fatal(e)
}

Something like this would be helpful:

t.Assert(test.Equals(obtained, expected))

Could look something like this:

func (c *common) Assert(err ...error) {
    args := make([]error, 0, len(errs))
    for _, e := range err {
        if e != nil {
            args = append(args, e)
        }
    }
    if len(args) > 0 {
        c.log(fmt.Sprintln(args...))
        c.FailNow()
    }
}

Or even this:

func (c *common) Assert(err error) {
    if err != nil {
        c.log(err.Error())
        c.FailNow()
    }
}
