#270 Study replacements for TET

[Joseph Koshy]

It is unclear whether TET is really open-source.

While the TET website claims that it is opensource under an "Artistic" license, the actual license that is present in the released version of the TET toolkit appears to be a restrictive one.

One option for us would be to create an alternative, BSD-licensed, test harness that is good enough for our own needs.

Selected ATF as the replacement for TET. The test/libtest hierarchy will be removed shortly.

2018/12/25
An API for writing tests is being implemented under test/libtest.

2010/08/09
The current (v3.8) TET source distribution appears to have been updated to include a copy of the "Artistic" license.

Possible alternatives:

• Kyua, the successor of NetBSD's ATF.
• wvtest.
• BATS for shell based tests.
• greatest
• theft - property based testing for C.

I like the Kyua suggestion -- it's in use for the FreeBSD base system test cases now.

Correct a link.

Another alternative is LLVM's test infrastructure. I find it to be very developer-friendly.

@emaste Thanks for your suggestions.

I am inclined to go with ATF/Kyua because (a) it is available out of the box in many *BSD OSes today and (b) it also suffices for our testing needs.

Converting our current TET-based test suites to use ATF's APIs appears to be a SMOP (a Simple Matter of Programming), i.e. slightly tedious, but feasible.
