If you want it, you'll probably have to find a +@c REALLY OLD dump tape~dots{}) +@c +@c The ~file{test/} directory is used for regression testing. +@c After you modify ~@code{_AS__}, you can get a quick go/nogo +@c confidence test by running the new ~@code{_AS__} over the source +@c files in this directory. You use a shell script ~file{test/do}. +@c +@c The tests in this suite are evolving. They are not comprehensive. +@c They have, however, caught hundreds of bugs early in the debugging +@c cycle of ~@code{_AS__}. Most test statements in this suite were naturally +@c selected: they were used to demonstrate actual ~@code{_AS__} bugs rather +@c than being written ~i{a prioi}. +@c +@c Another testing suggestion: over 30 bugs have been found simply by +@c running examples from this manual through ~@code{_AS__}. +@c Some examples in this manual are selected +@c to distinguish boundary conditions; they are good for testing ~@code{_AS__}. +@c +@c ~subsubsection Regression Testing +@c Each regression test involves assembling a file and comparing the +@c actual output of ~@code{_AS__} to ``known good'' output files. Both +@c the object file and the error/warning message file (stderr) are +@c inspected. Optionally the ~@code{_AS__} exit status may be checked. +@c Discrepencies are reported. Each discrepency means either that +@c you broke some part of ~@code{_AS__} or that the ``known good'' files +@c are now out of date and should be changed to reflect the new +@c definition of ``good''. +@c +@c Each regression test lives in its own directory, in a tree +@c rooted in the directory ~file{test/}. Each such directory +@c has a name ending in ~file{.ret}, where `ret' stands for +@c REgression Test. The ~file{.ret} ending allows ~code{find +@c (1)} to find all regression tests in the tree, without +@c needing to list them explicitly. +@c +@c Any ~file{.ret} directory must contain a file called +@c ~file{input} which is the source file to assemble.
