aix3!wjg (Joey Gibson) asked about the trap test.

The trip test is a series of torture tests that poke at the edges
of a TeX implementation, ensuring that the things that Don Knuth
felt were absolutely necessary for a program to be capable of
are there. If a program fails the trip test, it cannot be rightly
named TeX.

The trap test is a similar selection of tortures to be inflicted on
a METAFONT wanna-be. If it doesn't pass Trap, it's not METAFONT.

When the emTeX docs claim that emTeX has passed the trip test,
they are telling you that any source file that compiles and produces
typeset output on any other Trip-certified TeX implementation will
[will == can] be expected to produce the same output. (Mind you,
you can make it appear otherwise by changing printers, but that's
not really fair!)
