idea: helper for auto cleanup of tempfile

[Seth Hoenig]

There is t.TempDir which creates a tmp directory and cleans itself up at the end of the test. It would be nice if there was something similar for a single file.

var filename string
must.TmpFile(t, "content", &filename) 

[Seth Hoenig]

I still want this but not like in the example above. The problem is I never want test.* or must.* assertions to return a value. They should either fail the testing.T or not. But at the same time creating a variable for the filename and passing it to be set by reference like in the example above is too messy.

So perhaps we could have a testhelp package (name TBD) with helper functions that [may] return values.

filename := testhelp.TmpFile(t, "content")
